Changelog
All notable changes to this project will be documented in this file.
The format is based on Keep a Changelog and this project adheres to Semantic Versioning, specifically the variant used by Rust.
[0.16.7] - 2021-02-13
Fixed
- Usage of the logging system with a GStreamer library with the logging system compiled out does not crash any longer.
- Double-free in
gst_video::VideoTimeCode
API when converting between validated and unvalidated timecodes.
Added
gst::Element::get_current_state()
andget_pending_state()
convenience APIs.gst_audio::AudioConverterConfig
for setting the configuration on e.g. theaudiomixer
element. The low-levelAudioConverter
API is still not included in the bindings.
0.16.6 - 2020-12-20
Fixed
VideoTimeCodeInterval
'sOrd
andPartialEq
implementations compare against the correct fields now.SDPMessage::medias_mut()
iterator does not crash any longer.
Added
PartialEq
andEq
implementations onVideoAlignment
.- Alignment API for
VideoMeta
andget_plane_height()
/get_plane_size()
. VideoInfo::align_full()
.
0.16.5 - 2020-11-23
Fixed
- Make sure to use
$crate
in more macros to allow them to work without anything special in scope already. - Update documentation location.
- Don't panic if C code stores invalid seqnums in events and the seqnum is
used directly or via the
Display
impl. - Fix docs build for some crates on docs.rs.
- Fix
Debug
impl forgst_video::VideoTimeCode
to print the correct type name. - Fix plugin version to be 1.18 instead of 1.17 when compiling a plugin with
v1_18
.
Added
- Event handling support in pad probes, that is returning
PadProbeReturn::Handled
for events. EventRef::get_structure_mut()
getter that allows changing the events' structures.
Changed
- Remove unnecessary
PhantomData
markers and userepr(transparent)
instead ofrepr(C)
where it is more correct.
0.16.4 - 2020-10-09
Fixed
- Correctly implement
ExactSizeIterator
on theAudioFormat
andVideoFormat
iterators. Previously they returned the overall size instead of the remaining size, and they didn't implementIterator::size_hint()
. - Don't implement
ExactSizeIterator
on the buffergst::Meta
iterator. The overall length is not known easily and the implementation would've simply panicked in the past.
Added
gst::ClockID::wait_async_stream()
for async integration for clock waiting.From
/TryFrom
impls for converting betweengst::ClockTime
andstd::time::Duration
.
0.16.3 - 2020-09-08
Fixed
- Reset vfuncs if calling
BaseTransformClass::configure()
multiple times. - Fix
gst::debug_remove_default_log_function()
to actually remove the default log function.
Added
- Some more new APIs added in 1.18.
- API for getting an owned buffer from a readable
gst_video::VideoFrame
/VideoFrameRef
.
Changed
- Updated bindings to 1.18.0. This stabilized GStreamer 1.18 support and any API behind the "v1_18" feature is considered stable now.
- Factor out some common code from
gst::Pad::ProbeInfo
code. This reduces the code generated for each pad probe considerably. - Update paste dependency to 1.0 and pretty-hex to 0.2.
0.16.2 - 2020-07-27
Fixed
- Use correct pointer for the plane data in
gst_audio::AudioBuffer
.
Added
- Add
gst::GhostPad
convenience constructors that take a target pad, similar to the ones that existed in 0.15 and before. - Add
gst::parse_bin_from_description_with_name
that allows setting a name for the created bin without having to use unsafe code in application code.
0.16.1 - 2020-07-10
Fixed
- Allow calling
gst::DebugCategory::new()
beforegst::init()
again.
0.16.0 - 2020-07-06
Added
- Updated bindings to 1.17.2, adding experimental 1.18 support. This can be opted-in via the "v1_18" feature flag but there might still be API changes in the newly added API.
gst::MemoryRef::dump()
for dumping contents of a memory.gst::Bus::stream()
instead of a custom constructor on theBusStream
.- Use more accurate types for
Seqnum
,GroupId
andMetaSeqnum
. These are now proper wrapper types instead of plain integers, which makes mis-use harder. - Provide
TryFrom
impls for conversion betweenglib::DateTime
andgst::DateTime
. - Add
get_allocator()
functions togst_base::{Aggregator, BaseTransform, BaseSrc}
, and allow overridingBaseSrc::alloc()
. - Add subclassing bindings for
gst_base::PushSrc
. - Add new
gst::BufferCursor
API that allows to handle a buffer asRead
,Write
andSeek
and accesses the underlying memories of the buffer individually without mapping them all together. - Add
gst::Plugin::get_plugin_name()
. - Support for
gst_video::VideoAFDMeta
andVideoBarMeta
. - API for getting all / iterating over all
gst_audio::AudioFormat
andgst_video::VideoFormat
. - Bindings and subclassing bindings for
gst_video::VideoSink
. gst::Pad
can be constructed via the builder pattern andgst::PadBuilder
now, which allows to safely set the pad functions and various other fields during construction. ThePadBuilder
works on anygst::Pad
subclass and also has special support forGhostPad
s by allowing to set pad functions of the proxy pad.gst::Message
,gst::Event
andgst::Query
type constructors are now on the specific target type instead of variousnew_XXX()
functions on the basic type. E.g.gst::message::Eos::new()
.- Support for overriding
gst_audio::AudioSrc/Sink::reset()
. - Support for overriding
gst_base::BaseParse::stop()
. - Support for overriding
gst::Element::post_message()
. - Added bindings for
gst::BufferList::foreach()
andforeach_mut()
. - Added bindings for
gst::Buffer::foreach_meta()
andforeach_meta_mut()
.
Fixed
- Allow using any
glib::Object
as target object for logging instead of justgst::Object
. - Remove restriction API from
gst_pbutils::EncodingContainerProfile
. They are supposed to be used only with the other encoding profiles. - Return
&'static str
for variousgst::StructureRef
functions where the string is backed by aglib::Quark
. - Fix various
gst::DateTime
functions to actually returnOption
s. - Add support for filling in a buffer passed to the
gst::Pad
getrange function, allow passing one in intoget_range()
andpull_range()
and provide the corresponding API ongst_base::BaseSrc
too. - Allocator in audio/video
Decoder
base classes is optional and can returnNone
. gst_video::ValidVideoTimeCode::add_interval()
always returns a valid timecode again.- Allow resolving a
gst::Promise
withNone
and also handle that correctly in the callback. This is allowed by the API. - Allow calling various debugging related functions before
gst::init()
. - Various enum/function versions were fixed to only show up if the corresponding version feature is enabled.
gst::Pad
function setters are marked unsafe now as changing the functions is not thread-safe.- Remove
gst::Object::set_name()
as changing the name after construction generally causes problems and is potentially unsafe. - Remove
gst::Pad::set_pad_template()
as changing the pad template after construction is generally unsafe. gst::Pad::stream_lock()
borrows the pad now instead of taking a new reference.- Unimplemented
Jitter
andBuffer
queries were removed from the bindings. These are not implemented in C and only have a type registered. - Various
LAST
,NONE
variants of enums and flags were removed as these only make sense in C. - Call the parent impl of various vfuncs that were omitted before to not require further subclasses of them to implement them but automatically call the parent ones.
Changed
- Use
NonZeroU64/U32
for various ID types to allow further optimizations. - Use
thiserror
crate for deriving error types. - Switch from
lazy_static
toonce_cell
. - Change various miniobject functions like
gst::Caps::append()
from taking the object by value to modifying it internally. This makes them easier to use and only applies to functions that are defined on the non-reference type and take ownership of the values passed in. - Use
mem::ManuallyDrop
instead ofmem::forget()
everywhere. - Replace most
mem::transmute()
calls with safer alternatives. gst:StreamCollection
API was changed to the builder pattern for construction as the collection must not be changed after construction.gst::ProxyPad
default functions are plain functions onProxyPad
now instead of trait functions to allow easier usage of them.- Use proper error types in various
TryFrom
impls. gst_video::VideoMeta::add()
returns aResult
now instead of panicking.- Various constructors were renamed from
new_with_XXX()
andnew_from_XXX()
to the more idiomaticwith_XXX()
andfrom_XXX()
. - Miniobject bindings are simplified now and there is no
gst::GstRc
type anymore, instead everything is directly implemented on the concrete types. As part of this thegst::MiniObject
trait was also removed as it was unneeded now.
0.15.7 - 2020-06-08
Fixed
- Allow multiple filter types per process with
gst::Iterator::filter()
. - Check that
VideoInfo
is valid when creating aVideoFrame
. - Don't potentially dereference a
NULL
pointer when getting the format from an invalidVideoInfo
orAudioInfo
. - Don't unmap borrowed
VideoFrameRef
s.
Added
gst::ProtectionMeta
,gst_video::VideoAffineTransformationMeta
,VideoCropMeta
andVideoRegionOfInterestMeta
bindings.- Various new
gst_rtp::RTPBuffer
methods. gst_audio::audio_buffer_truncate()
,AudioMeta
andAudioBuffer
bindings.
0.15.6 - 2020-05-28
Fixed
- Assert that the data passed to
VideoCaptionMeta::add()
is not empty. - Don't store strong references to the object in the bus, appsink and appsrc
futures
Stream
/Sink
adapters. This would keep them alive unnecessarily and would prevent theStream
/Sink
to ever "finish" on its own. - Handle receiving a
None
reply in the change function ofgst::Promise
. This is apparently valid. For backwards compatibility reasons this is currently replaced with an empty structure but in 0.16 the API will explicitly handleNone
.
Added
gst::Stream::debug()
andgst::StreamCollection::debug()
for converting into a structured string with the actual contents of each.gst::Structure::from_iter()
andgst::Caps::from_iter()
to create structures/caps from iterators.gst::Event
support for getting/setting thegst::Stream
in theStreamStart
event.gst_video::calculate_display_ratio()
and::guess_framerate()
.- Various video related
gst::CapsFeatures
ingst_video
. TryFrom
/From
impls for converting betweengst::Structure
andgst_video::VideoConverterConfig
.- Various
glib::Value
trait impls forSDPMessage
,StructureRef
,CapsFeatureRef
and all borrowed variants of miniobjects to be able to work with the borrowed, non-owned variants when handlingglib::Value
s.
0.15.5 - 2020-05-03
Fixed
- Revert: Allow logging any
glib::Object
and not justgst::Object
. This broke API in subtile ways and needs to wait until 0.16 - Replace
%
in log output with%%
to prevent accidental C formatting - Add missing manual traits to the documentation
Added
BufferRef::peek_memory_mut()
to give a mutable reference to a given memory- Different iterators for iterating over the memories of a buffer
- Support for
gst_audio::AudioClippingMeta
gst::Plugin::get_plugin_name()
was addedgst::Element::get_current_clock_time()
and `gst::Element::get_current_running_time() helper functionsgst::State
andStateChange
API for calculating next/previous state and convert from/to the components of a state change
Changed
- Use
mem::ManuallyDrop
instead ofmem::forget
everywhere
0.15.4 - 2020-03-09
Fixed
- Allow logging any
glib::Object
and not justgst::Object
- Fix floating reference handling in
RTSPMedia::take_pipeline()
- Hold
GMutex
guards for the remainder of the function and warn if they're directly dropped - Work around empty/any caps handling bugs in
Caps::fixate()
Added
- Add
BaseTransform::prepare_output_buffer()
subclassing support RTSPServer
,RTSPClient
,RTSPMedia
andRTSPMediaFactory
subclassing support- Handle panicking in
appsrc
/appsink
callbacks by posting an error message instead of killing the process
0.15.3 - 2020-02-15
Fixed
UniqueFlowCombiner::clear()
should take a mutable reference.AudioStreamAlign
doesn't require mutable references for getters anymore.- Don't use bool return value of
gst_video_info_set_format()
andgst_video_info_align()
with GStreamer < 1.11.1 as it returned void back then. We'd otherwise use some random value. - Make
VideoInfo::align()
is available since 1.8. - Fix changing/clearing of
AppSrc
,AppSink
callbacks andBus
sync handler. Before 1.16.3 this was not thread-safe and caused crashes. When running with older versions changing them causes a panic now and unsetting the bus sync handler has not effect. With newer versions it works correctly.
Added
- Add
Clone
impls forBufferPoolConfig
andPlayerConfig
. - Add
VideoConverter
bindings. - Add
Future
s variant forgst::Promise
constructor. - Add
Future
s variant forgst_video::convert_sample_async()
. - Add
submit_input_buffer()
,generate_output()
,before_transform()
,copy_metadata()
andtransform_meta()
virtual method support forBaseTransform
. - Add
AppSink
Stream
adapter andAppSrc
Sink
adapter for integrating both into Rust async contexts.
Changed
- More generic implementations of
VideoFrame
/VideoFrameRef
functions to allow usage in more generic contexts.
0.15.2 - 2020-01-30
Fixed
- Fix another race condition in the
gst::Bus
Stream
that could cause it to not wake up although a message is available.
0.15.1 - 2020-01-23
Added
- Use static inner lifetime for
VideoCodecState<Readable>
so that it can be stored safely on the heap. - Getters/setters for
BinFlags
ongst::Bin
. gst::Caps::builder_full()
for building caps with multiple structures conveniently.gst::Element::call_async_future()
for asynchronously spawning a closure and returning aFuture
for awaiting its return value.
Fixed
- Various clippy warnings.
- Getters/setters for
PadFlags
ongst::Pad
now provide the correct behaviour. - Take mutex before popping messages in the
gst::Bus
Stream
to close a small race condition that could cause it to not be woken up. gst::ChildProxy
implementers do not have to providechild_added()
andchild_removed()
functions anymore but these are optional now.- Manually implement
Debug
impls for various generic types where toDebug
impl should not depend on their type parameters also implementingDebug
.
0.15.0 - 2019-12-18
Added
StructureRef::get_optional()
for returningNone
if the field does not exist instead ofErr
- Bindings for
gstreamer-rtp
library, mostlyRTPBuffer
- Support for writing
Preset
,TagSetter
,Clock
,SystemClock
subclasses - Bindings for
Typefind::get_length()
- Bindings for
BaseSrcImpl::get_times()
- Bindings (incl. subclassing) for
AudioSink
andAudioSrc
- Missing
Send
/Sync
impl for various types
Fixed
- Cleanup of cargo features/dependencies to improve build times
- Serde serialization with optional values. Attention: This changes the format of the serialization!
VideoEncoder
/VideoDecoder
proxy_getcaps()
can't returnNone
- Use non-panicking UTF8 conversion in log handler. We don't want to panic just because some C code printed a non-UTF8 string
- Re-rexport all traits from the crate level and also ensure that all traits are actually included in the preludes
- Actually export
is_video_overlay_prepare_window_handle_message()
function - Use
FnMut
for theappsink
callbacks instead ofFn
Promise
change function returns the actual reply to the promise now instead of just passing the promise itself- Memory leak in
Iterator::filter()
BinImpl::add()
takes ownership of floating referencesDeviceImpl::create_element()
preserves floating flagBinImpl::remove()
takes a strong reference of the element now as the last reference might be owned by the bin and otherwise we would potentially have a use-after-free afterwardsBaseParseFrame
andVideoCodecFrame
take a&mut self
now for various functions that actually change the frame
Changed
- Minimum supported Rust version is 1.39
- Allow passing
None
toVideoEncoder::finish_frame()
- Various
to_string()
methods were moved into theDisplay
trait impl and for some typesto_str()
was added to return a&'static str
- .gir files were updated to 1.16.2 release
Sample
constructor uses the builder pattern nowVideoMeta::add_full()
is simplified and requires parametersBasetransformImpl::set_caps()
returns aResult
instead ofbool
- SDP data type getters for strings return an
Option
now as these can beNone
in practice although not allowed by the SDP spec - Various functions returning
Option
s were changed to returnResults
ifNone
actually signalled an error instead of just a missing value
Removed
- "subclassing" and "futures" cargo features. These are enabled by default now
[0.14.5] - 2019-09-17
Added
- Support subclassing of
gst::Device
,gst::DeviceProvider
,gst_audio::AudioDecoder
and::AudioEncoder
- Support for
Element::set_clock
and::provide_clock
virtual methods ElementClass::add_metadata
was addedgst_video::VideoDecoder
and::VideoEncoder
got support forget_caps
,negotiate
,src/sink_query/event
and thedrain
virtual methodsElement::num_pads
,::num_src_pads
and::num_sink_pads
functionsgst_video::VideoDecoder
and::VideoEncoder
gotget_allocator
bindingsgst::Iterator
implementsIntoIterator
now for providingstd::iter::Iterator<Item=<Result<T, IteratorError>>
adapter- Error macros for audio/video decoder subclasses to handle decoding errors more gracefully and only actually error out after many consecutive errors
Fixed
- Macros now also work in Rust 2018 edition without
#[macro_use]
but explicit imports - The log handler unit test runs reliable in parallel with other tests
- Manually implement
Debug
forgst::Iterator
to allow it for anyT
instead ofT: Debug
Device::create_element
has correct reference count handling now- Return
NotNegotiated
in the video codec base classes if setting the output state fails instead ofError
[0.14.4] - 2019-08-14
Added
- Bindings for adding/removing custom log functions
- Bindings for
calculate_linear_regression()
- Constants for base class custom flow returns
Fixed
- Ownership of pad in
Element::release_pad()
virtual method implementations
[0.14.3] - 2019-07-16
Added
Buffer::unset_flags()
for unsetting specific buffer flagsVideoBufferFlags
flags type andVideoBufferExt::set_video_flags()
,unset_video_flags()
andget_video_flags()
for working with video buffer flags from safe code.
Fixed
- Setting buffer flags does not override arbitrary other flags anymore but
only sets the flags in question. This is necessary to not override extension
buffer flags like
gst_video::VideoBufferFlags
.
0.14.2 - 2019-07-15
Added
- Support for
ReferenceTimestampMeta
0.14.1 - 2019-07-06
Added
- Various new WebRTC enum types from 1.14.1/1.16.0
Fixed
- Correctly generate interlaced
VideoInfo
by usinggst_video_info_set_interlaced_format()
instead of the generic function. - serde serialization unit tests for
gst::format
succeed again now.
Changed
Debug
impls forVideoFormatInfo
andAudioFormatInfo
now print all the details of the format instead of only the name, and theDebug
impls forVideoInfo
andAudioInfo
also print the format now.
0.14.0 - 2019-06-24
Added
- Bindings for
GLSyncMeta
. - Bindings for setting/getting
TagScope
on aTagList
- Bindings for
GLDisplayWayland
andGLDisplayX11
in addition to the already existingGLDisplayEGL
- Bindings for
Bus::pop_filtered()
and related functions - Bindings for getting/setting
Object
,Element
,Bin
,Pipeline
andPlugin
flags - Bindings for
VideoCaptionMeta
Debug
impl ofBuffer
now also shows the metas of the buffers- Expose flow return in
PadProbeInfo
for overriding the return value - Bindings for
VideoDecoder
andVideoEncoder
, including subclassing support - Bindings for
Memory
,Allocator
andVideoBufferPool
- Bindings for
VideoFormatInfo::pack
and::unpack
for format conversion - Bindings for
BaseParse
, including subclassing support - Various new arithmetic operation impls for fractions, formatted values and
ClockTime
- Bindings for
VideoInfo::align()
Changed
- The
SDPMessage
andSDPMedia
bindings were completely rewritten as they were broken before and caused crashes in various usages. As part of this there's also some more convenience API available on these types, like iterators for example, and API to modify theSDPMedia
contained in aSDPMessage
. - Update to GStreamer 1.16.
- Regenerate with latest gir.
- Run all autogenerated code through rustfmt after generation too.
- Updated to latest versions of GLib/GIO/etc crates.
- Updated to futures 0.3 /
std::future
ProxyPad
default functions moved to an extension trait instead of plain functions onProxyPad
, making them more in sync with the defaultPad
functions- GStreamer plugins are now exporting the new 1.14+ plugin symbols if they were configured for GStreamer 1.14+
- Arithmetic operations on formatted values and
ClockTime
do overflow checks now and replace the result with theNONE
value on overflow TryFrom
/TryInto
traits are used in various places now instead of the previous ad-hoc implementations of them.- Registering element/typefind/device monitor factories requires passing a
value of
gst::Rank
now instead of an arbitraryu32
Fixed
- Use correct type for destroying pad task closure data. This was previously using the wrong type, causing crashes at runtime.
DeviceAdded
/DeviceRemoved
message getters are transfer full so we don't need to take an additional reference that would be leaked.AppSink
callbacks are correctly marked asSend
instead ofSend+Sync
, allowing a wider range of closures to be used for them.- Handle
PadProbeReturn::Handled
return values from pad probes more correctly. ToOwned::to_owned()
on miniobjects has to create copies instead of only increasing the reference count. Otherwise it was possible to create multiple mutable and immutable references to the same object at the same time.- Various functions take references to owned miniobjects instead of borrowed references as it was otherwise possible to create multiple mutable or immutable references to the same object at the same time.
URIHandler::set_uri
does not acceptNone
anymore as this is not allowed by the C function.- Comparisons and addition of
TypeFindProbability
andRank
work correctly now - Various
Display
implementations were fixed to not cause a stack overflow due to infinite recursion anymore - Various
::to_string()
functions don't take ownership of C strings anymore that they do not own, which caused double frees before
Removed
- MIKEY related bindings from the SDP library. The bindings were broken and until someone needs them these are not available anymore.
0.13.0 - 2019-02-22
Added
- Subclassing infrastructure was moved directly into the bindings,
making the
gst-plugin
crate deprecated. This involves many API changes but generally cleans up code and makes it more flexible. Take a look at thegst-plugins-rs
crate for various examples. - Bindings for GStreamer GL library
- Bindings for
CapsFeatures
andMeta
- Bindings for
ParentBufferMeta,
VideoMetaand
VideoOverlayCompositionMeta` - Bindings for
VideoOverlayComposition
andVideoOverlayRectangle
- Bindings for
VideoTimeCode
- Bindings for
NetAddressMeta
- Bindings for registering custom tags
UniqueFlowCombiner
andUniqueAdapter
wrappers that make use of the Rust compile-time mutability checks and expose more API in a safe way, and as a side-effect implementSync
andSend
nowBus::add_watch_local()
andgst_video::convert_frame_async_local()
that allows to use a closure that does not implementSend
but can only be called from the thread owning the main context.- More complete bindings for
Allocation
Query
pbutils
functions for codec descriptionsTagList::iter()
for iterating over all tags while getting a single value per tag. The old::iter_tag_list()
function was renamed to::iter_generic()
and still provides access to each value for a tagBus::iter()
andBus::iter_timed()
iterators around the corresponding::pop*()
functions- Getters for
VideoColorimetry
to access its fields Debug
impls for various missing types.- serde serialization of
Value
can also handleBuffer
now - Extensive comments to all examples with explanations
- Transmuxing example showing how to use
typefind
,multiqueue
and dynamic pads - basic-tutorial-12 was ported and added
Changed
- Rust 1.31 is the minimum supported Rust version now
- Update to latest gir code generator and glib bindings
- Functions returning e.g.
gst::FlowReturn
or other "combined" enums were changed to return split enums likeResult<gst::FlowSuccess, gst::FlowError>
to allow usage of the standard Rust error handling. - Various functions and callbacks returning
bool
orOption<_>
were changed to return aResult<_, glib::BoolError>
orResult<_, gst::LoggableError>
orResult<_, gst::ErrorMessage>
for better integration with Rust's error handling infrastructure. - Some infallible functions returning
bool
were changed to return()
. MiniObject
subclasses are now newtype wrappers around the underlyingGstRc<FooRef>
wrapper. This does not change the API in any breaking way for the current usages, but allowsMiniObject
s to also be implemented in other crates and makes surerustdoc
places the documentation in the right places.BinExt
extension trait was renamed toGstBinExt
to prevent conflicts withgtk::Bin
if both are importedBuffer::from_slice()
can't possible returnNone
Fixed
gst::tag::Album
is the album tag now instead of artist sortname- Return
0
for the channel mask corresponding to negativeAudioChannelPosition
s. PartialOrd
and related traits are implemented via pointer equality onClockId
instead of using the compare function. Two clock ids with the same timestamp are not necessarily the same.- Various functions that are actually fallible are now returning an
Option<_>
. - Various
clippy
warnings
0.12.2 - 2018-11-26
Fixed
- PTP clock constructor actually creates a PTP instead of NTP clock
Added
- Bindings for GStreamer Editing Services
- Bindings for GStreamer Check testing library
- Bindings for the encoding profile API (encodebin)
- VideoFrame, VideoInfo, AudioInfo, StructureRef implements Send and Sync now
- VideoFrame has a function to get the raw FFI pointer
- From impls from the Error/Success enums to the combined enums like FlowReturn
- Bin-to-dot file functions were added to the Bin trait
- gst_base::Adapter implements SendUnique now
Changed
- All references were updated from GitHub to freedesktop.org GitLab
- Fix various links in the README.md

- Remove GitLab badge as that only works with gitlab.com currently
0.12.1 - 2018-09-21
Added
- More complete bindings for the gst_video::VideoOverlay interface, especially gst_video::is_video_overlay_prepare_window_handle_message()
0.12.0 - 2018-09-08
Added
- Bindings for the GStreamer SDP and WebRTC libraries
- Generic API for working with tags that is based on string tag names and glib::Value for the tag values
- Bindings for Aggregator and AggregatorPad
- Bindings for BaseTransform/BaseSrc::get_buffer_pool()

Changed
- Use ptr::NonNull in various places
- Updated to muldiv 0.2, num-rational 0.2
- Bus::create_watch() can't return None
- Remove CallbackGuard as unwinding across FFI boundaries is not undefined behaviour anymore but will directly cause a panic
- Changed from the futures to the futures-preview crate as an optional dependency
- Various Caps operations take a &CapsRef instead of &Caps
- "deep-notify" signal takes the whole ParamSpec as parameter instead of only the signal name
- Some structs were changed from empty struct to empty enums
- Pad probe code does not take an additional reference to the data anymore, potentially passing writable events/buffers into the probe
- ValueExt::compare() is implemented around std::cmp::Ordering now instead of a custom enum that was basically the same
Fixed
- Pad::add_probe() can return None if an IDLE probe was already called and removed in the meantime
- Various compiler and clippy warnings
Removed
- std::Iterator impl for gst::Iterator. It was awkward to use because the gst::Iterator could fail at each iteration
0.11.6 - 2018-08-27
Fixed
- Build with NLL/two-phase borrows
- Explicitly define [bin] section for discoverer example to fix a cargo warning
Added
- Add unsafe gst::deinit() function
- Ord/PartialOrd impls on gst::Seqnum
- Getter for current pad mode
- gst::Pad::sticky_events_foreach() for iterating over all sticky events in a thread-safe way
0.11.5 - 2018-07-24
Fixed
gst::Bus
's sync handler must unref every message ifgst::BusSyncReply::Drop
is returned, otherwise they are all leaked
0.11.4 - 2018-07-19
Fixed
gst::Caps::subtract()
does not leak its arguments anymoregst::Caps::get_structure()
gracefully returnsNone
if the index is out of bounds instead of ag_return_val_if_fail()
gst::Structure::new()
has to give away ownership of the info structure but didn't. For 0.11 we internally copy, in 0.12 it will take the info structure by value- Typefind tests don't fail anymore if the system has typefind factories without caps
Added
- An additional assertion that ensures that miniobjects are actually writable before creating a mutable reference
0.11.3 - 2018-06-08
Added
gst::Bus::remove_watch()
is now available to remove a bus watch againfmt::Debug
impls forAudioInfo
andVideoInfo
were addedfmt::Debug
impls for mini objects also print the pointer value now to make it easier to track them in debug logsPlayerVisualization
has accessors for the name and description fields now, without which there is no sensible way to use them or to set a player visualization
0.11.2 - 2018-05-09
Fixed
- Work-around various floating reference handling changes between 1.12 and 1.14 to be able to run with both versions without memory leaks or other reference count problems. This affects NetTimeProvider, BufferPool, DeviceMonitor, Stream, StreamCollection, and Player, NetClientClock, NetClock, PtpClock which were already previously fixed.
Changed
- Change the appsrc need-data and all appsink callbacks to not require the Sync bound anymore and change from Fn to FnMut. They can only be called from a single thread at a time. This change is only done for the corresponding callbacks, not the signals.
0.11.1 - 2018-04-07
Fixed
- Fix Structure::to_string() to not run into an infinite recursion but call the method on the contained StructureRef instead of on itself
0.11.0 - 2018-03-20
Changed
- Updated everything to GStreamer 1.14.0
- Event, Message and Query types were refactored to improve usability. Especially newly constructed queries allow to directly use the type-specific functions to be used without first creating a view
- VideoFrameRef::copy_to_ref() and ::copy_plane_to_ref() are gone now and the original functions work with refs instead of full frames
- PadProbeId and NotifyIds are not Copy/Clone anymore and are taken by value
- GstPlayer has GstObject as parent class now
Added
- GstPbutils, GstSdp, GstRtsp and GstRtspServer bindings
- GstPromise, GstAudioStreamAlign and various other 1.14 API
- GstVideoFilter and GstBufferPool bindings
- Element::call_async()
- Debug impl For Toc and TocEntry
- Various new examples (RTP FEC, RTSP server, tag usage, ...)
Fixed
- Memory leak in gst_video::convert_sample_async()
0.10.2 - 2018-02-18
Fixed
- Fix building of messages with custom fields for types that don't have a GstStructure
Added
- VideoFrameRef::copy_to_ref() and ::copy_plane_to_ref(), which work with VideoFrameRefs instead of full VideoFrames
- Getters for the BaseSrc/Sink/Transform configured segment
- Document the gstreamer-player-1.0 dependency in the README.md
0.10.1 - 2018-01-03
Fixed
- Don't require &mut self for TagSetterExtManual::add()
Added
- A TagSetter example application
- Bindings for gst_video::convert_sample() and ::convert_sample_async()
- Bindings for gst_video::VideoRectangle
- Debug impl for Sample and ::with_buffer_list() constructor
- A borrowing version of VideoFrame: VideoFrameRef
- Bindings for GstVideoFilter
Changed
- Deprecated Sample::get_info() in favour of ::get_structure()
- Player has gst::Object as another parent class now
0.10.0 - 2017-12-22
Fixed
- Various clippy warnings
- Memory leak of the tag list in Toc::merge_tags()
- Property getters use Values of the correct type
- Event::get_structure(), Message::get_structure() and Query::get_structure() can return None for the structure
- Various other nullability fixes all over the API, changing functions to accept Option<> or returning Option<>, or only plain types
- Functions taking paths/filenames now actually take Paths instead of &strs
- Element::remove_pad() is not giving away a new reference to the pad anymore, which caused a memory leak of all pads ever removed
- Precision handling in ClockTime's Display impl
- Video/AudioInfo are only Send, not Sync
Added
- Various enums now also derive useful traits like Copy, Clone and Hash in addition to PartialEq, Eq and Debug
- TagList::merge() and insert() for combining tag lists
- EventType gained many useful functions to work with event types and a PartialOrd impl to check expected event order of event types where it matters
- MessageRef/EventRef/QueryRef implement ToOwned
- Bindings for Registry and PluginFeature
- Event::set_running_time_offset() for adjusting the offset while events pass through the pipeline
- Event/Message GroupIds and Seqnums now have a newtype wrapper around u32 instead of the plain value, making usage of them slightly more typesafe. Also add an "invalid" value for both, as exists in latest GStreamer now.
- FormattedValue, GenericFormattedValue and related types were implemented now, which allows more convenient and type-safe usage of formatted values (time, bytes, etc)
- Bindings for force-keyunit and still-frame events were added
- MappedBuffer/BufferMap now implement various other useful traits, including AsRef<[u8]>, AsMut, Deref, DerefMut, Debug, PartialEq and Eq
- Add VideoMultiviewFramePacking enum, and use it in Player
- Bindings for the GStreamer Net library, including PTP/NTP/network client clocks and the GStreamer NetClock provider for network synchronization of pipelines
- IteratorError implements std::error:Error
- Plugin::add_dependency() and ::add_dependency_simple() was added
- Rank and TypeFindProbability implement PartialOrd/Ord now
- Bindings for TypeFind, TypeFindFactory and the typefind helpers
- StreamCollection::iter() for iterating over all contained streams
- ErrorMessage type that can be used e.g. in a Result for passing an error message from somewhere to upper layers to then be posted on an element the same way gst_element_error!() would've done
Changed
- Sample::new(), TagList::add(), Structure::set() and similar functions take the values (ToSendValue impls) by reference instead of value. They were not consumed by the function before.
- The Debug impls of various types, including Event/Buffer/Message/Query/Structure were improved to print all the fields, similar to what GST_PTR_FORMAT would do in C
- Switched to lazy_static 1.0
- Gap event and Duration tag are using ClockTimes now, as well as various Player signals
- Segment is now based on a generic type FormattedSegment that can take any format (time, bytes, etc) or a GenericFormattedValue for more type-safety and convenience. Also functions for "casting" between a generic segment and a segment with a specific format exist on this now
- AppSrc and AppSink now have a builder for the callbacks, making it unnecessary to always provide all callbacks even if only one is actually needed
- Various functions that returned bool for errors, are now returning a Result
- Player configuration is now a custom type with more convenient API
- Player VideoInfo uses a Fraction instead of (u32,u32) for the framerate and pixel-aspect-ratio
- VideoFrame API has more consistent API between writable and read-only variants
- Buffer::copy_into() was added, and ::copy_region() now takes a BufferCopyFlags parameter instead of always using the default flags
- ChildProxy::set_child_property() takes a &ToValue now to follow the API of Object::set_property() and improve usability
- Proxy/GhostPad default pad functions use the correct specific pad type now instead of a generic Pad
- Bus::add_signal_watch_full() takes a Priority for the priority instead of u32
- Clock::(un)adjust_with_calibration() takes no clock parameter anymore
Removed
- FormatValue was removed in favour of GenericFormattedValue and the connected traits and specific format impls
0.9.1 - 2017-11-26
Fixed
- Export
FlowError
/FlowSuccess
,ClockError
/ClockSuccess
,PadLinkError
/PadLinkSuccess
too
0.9.0 - 2017-11-26
Added
- Bindings for (outputting to) the GStreamer logging system
- Bindings for the GStreamer base library
- Bindings for all the
Pad
functions to override pad behaviour, and pad task functions - Bindings for
StaticCaps
andStaticPadTemplate
- Bindings for
deep-notify
signal onObject
- Support for directly creating
Error
/Warning
/Info
Messages
and posting them from an element with context information (file, line, module, etc.) similar to the CGST_ELEMENT_ERROR
macro - Support for setting custom fields in
Messages
/Events
during construction - Support for creating Buffers out of anything that is
AsRef<[u8]>
orAsMut<[u8]>
- Support for using the
Read
trait onAdapter
- Functions for getting all sink/src/all pads of an
Element
, and all children of aBin
- Builder for
Caps
andStructures
in addition to the existing functions AppSrc
/AppSink
implementBaseSrc
/BaseSink
andURIHandler
- Rust ports of the basic tutorials 1 to 8 from https://gstreamer.freedesktop.org/documentation/tutorials/
- "Getting started" and "Installation" sections to the README.md
- "dox" feature for generating documentation for all available configurations
Fixed
StackTraceFlags
are only available since 1.12- Worked around macOS requiring a
NSRunLoop
running on the main thread in all examples and tutorials, to be able to show a window or anything else
Changed
ClockTime
is now a wrapper aroundOption<u64>
to handle theCLOCK_TIME_NONE
case better. This wrapper implements all the arithmetic and other traits as needed and ensures that no accidential calculations withCLOCK_TIME_NONE
can happen- "Values with format", like in
Duration
/Position
/Convert
queries orSeek
events now return aFormatValue
type. This contains the actualFormat
together with the value and does any required conversions. This also makes it harder to accidentially mix e.g. values in bytes and time PadProbeId
does not implementClone
/Copy
anymore- Property notify watches return a custom type instead of ulong
Error
/Warning
/Info
Messages
can only be created with specific kinds ofglib::Error
now. Using arbitrary ones does not workIterator
bindings were completely rewritten and provide the item type as a generic type parameter now, greatly simplifying its usage- All
glib::Values
are nowglib::SendValue
instead, e.g. inCaps
andStructures
, as their content must be possible to send to different threads safely Message::get_src()
can returnNone
- Allow
None
asCaps
inAppSrc
/AppSink
- Allow everything implementing
Into<Option<&str>>
to be used as a pad name - Moved
copy()
fromGstRc
directly toMiniObject
- Success/Error enums (like
FlowReturn
,PadLinkReturn
,StateChangeReturn
) now implement aninto_result()
function that splits them into aResult
with the good and bad cases. Also mark them as#[must_use]
to make it harder to accidentially ignore errors. - Error enums implement the
Error
trait - Many examples use the
failure
crate for error handling now, cleaning up the error handling code quite a bit - Lots of other code cleanup, compiler/clippy warning cleanup, etc.
0.8.2 - 2017-11-11
Fixed
- Implement StaticType of BufferRef instead of Buffer. Buffer aka GstRc already implements StaticType if BufferRef does, and without this it was not possible to use Buffers in GValues.
- Free memory of the appsink/appsrc callbacks with the correct type. It was crashing because of using the wrong type before.
- Fix documentation URLs in Cargo.toml.
Added
- Installation instructions and links to documentation for getting started to README.md.
0.8.1 - 2017-09-15
Added
- Implement Send+Sync for Query, Message and Event, and their corresponding Ref types.
Fixed
- Constructor for gst_player::Player now works properly with GStreamer 1.12 when passing a video renderer or signal dispatcher. There was a reference counting bug.
- Instead of returning &'static references from functions, return references with a generic, unbound lifetime instead. See https://github.com/rust-lang/rust/pull/42417#issue-233404573
- Various "unused external crate" warnings and clippy warnings everywhere.
Changed
- Remove Cargo.lock from GIT, it's not very useful for library crates.
- Run everything through latest rustfmt-nightly.
- Use while-let (instead of loop and if-let) and CLOCK_TIME_NONE (instead of u64::MAX) in the examples.
0.8.0 - 2017-08-31
- Initial release of the autogenerated GStreamer bindings. Older versions (< 0.8.0) of the bindings can be found here. The API of the two is incompatible.
