Instead of passing it structure by structure. This allows
better optimized transform_caps functions and allows better
transformation decisions.
See bug #619844.
Update the design docs with some clear rules for how sticky events are
handled.
Reimplement the sticky tags, use a small structure to hold the event and its
current state (active or inactive).
Events on sinkpads only become active when the event function returned success
for the event.
When linking, only update events that are different.
Avoid making a copy of the event array, use the object lock to protect the event
array and release it only to call the event function. This will need to check
if something changed, later.
Disable a test in the unit test, it can't work yet.
gst_pad_template_get_caps(), gst_pad_get_pad_template_caps()
and gst_pad_get_pad_template() return a new reference of the
caps or template now and the return value needs to be
unreffed after usage.
Improve GstSegment, rename some fields. The idea is to have the GstSegment
structure represent the timing structure of the buffers as they are generated by
the source or demuxer element.
gst_segment_set_seek() -> gst_segment_do_seek()
Rename the NEWSEGMENT event to SEGMENT.
Make parsing of the SEGMENT event into a GstSegment structure.
Pass a GstSegment structure when making a new SEGMENT event. This allows us to
pass the timing info directly to the next element. No accumulation is needed in
the receiving element, all the info is inside the element.
Remove gst_segment_set_newsegment(): This function as used to accumulate
segments received from upstream, which is now not needed anymore because the
segment event contains the complete timing information.
This allows to get the internal pad of ghostpads and
proxypads without using gst_pad_iterate_internal_links()
and is much more convenient.
The internal pad of a ghostpad is the pad of the opposite direction
that is used to link to the ghostpad target.
Highlights:
- new parser base class: GstBaseParse
- new core element: funnel
- OSX multi-arch fixes
- new QoS type for QoS events
- new progress message API to notify applications of asynchronous operations
- countless other fixes and improvements
Add a query to request allocation parameters and optionally a bufferpool as
well. This should allow elements to discover downstream capabilities and also
use the downstream allocators.
This allows to add pad templates and set metadata in class_init instead of
base_init. base_init is a concept that is not supported by almost all
languages and copying the templates/metadata for subclasses is the more
intuitive way of doing things.
Subclasses can override pad templates of parent classes by adding a new
template with the same now.
Also gst_element_class_add_pad_template() now takes ownership of the
pad template, which was assumed by all code before anyway.
Fixes bug #491501.
Seems like the best fit to what it does, and is shorter than
set_frame_properties() which might also have been confusing
because of GstBaseParseFrame.

This is more in line with e.g. GstBaseTransform's API, and makes for nicer
to read code. No getters for now since I don't see any use case for them,
the API is for subclasses, which usually know what format they're
dealing with already and hence know what they've set.

Add first implementation of arbitrary buffer metadata. We use a simple linked
linked of slice allocated metadata chunks. Future implementations could use
something more performant.
Add get, remove, iterate methods to handle the metadata.
Add function that (unlike the GLib equivalent) also accepts paths that
aren't absolute and will clean up relative markers such as ./ and ../
before forming a URI.
Fixes warnings with e.g. filesrc location=foo ! typefind caused by the
recent switch to g_filename_to_uri(), but also actually creates valid
URIs for the first time.
Windows code paths could need some more work, e.g. we don't clean up
the relative markers there for now (because path could have \ and /
as separators).
API: gst_filename_to_uri()
Add a first draft with some ideas and use cases for the implementation
for bufferpools. The purpose is to be able to make elements negotiate
their buffer requirements as well as provide an infrastructure to
preallocate and reuse buffers in an easy way.
So the encoding of the original document is respected and
displays properly in browsers where the encoding autodetection
fails to recognise that it's utf-8.

The new request_new_pad_full vmethod provides an additional caps field,
which allows elements to take better decision process.
Also, add a gst_element_request_pad() function to allow developers to be
able to specify which pad template they want a pad of.
Convert gstutils to use that new method instead of the old one when more
efficient.
This is useful for being able to request pads in a more flexible way,
especially when the element can provide pads whose caps depend on
runtime configuration and therefore can't provide pre-registered
pad templates.

Make GstObject extend from GInitiallyUnowned, remove the FLOATING flag and use
GObject methods for managing the floating ref.
Remove class lock, it was a workaround for a glib < 2.8 bug.
Remove the parent-set and parent-unset signals, attempt to implement with notify
but disabled because deadlocks in deep-notify.
Fix wrongly placed example and weirdly phrased 'note' lacking proper
formatting. Fix missing hint for autogen.sh location and rephrase
'built and installed' sentence. Fix wrongly phrased and redundant
paragraph in PWG

Add minimal math-compath.h header where we can define fallback
versions for miscellaneous math functions that aren't always
available, so we don't have to duplicate this in plugins.
The header is not included by default, so needs to be
included explicitly for now.

Adds a new tag to indicate the error in horizontal positioning
in meters. This is one of the available 'gps error' fields in
exif, for example.
API: GST_TAG_GEO_LOCATION_HORIZONTAL_ERROR
Add a function to retrieve a list of buffers containing the first N bytes from
the adapter. This can be done without a memcpy and should make it possible to
transfer the list to a GstBufferList later.
Add _set_value() variants that take ownership of the value passed
instead of making a copy of the value. This is useful for setting
values to things that aren't refcounted (e.g. GValueArrays or
strings or string arrays, etc.).
API: gst_structure_take_value()

Add a GstStructure to GstElementClass and GstElementFactory. Add setters/getter.
Handle it in the registry code. Print items in gst-inspect.

Added a new query type to retrieve informations about the areas of the
media currently buffered. See bug 623121.

Make code including GStreamer headers compile with -Wcast-qual by
maintaining const-ness when casting. Also fix function signature of
gst_byte_writer_set_pos(): the byte writer should not be marked as
const.

Adds GST_TAG_APPLICATION_DATA for representing arbitrary private
data that applications might want to store into tags. Exif/id3,
for example, have tags for this.
API: GST_TAG_APPLICATION_DATA
Fixes#626651
For some reason the static inline function GST_CAT_LEVEL_LOG_valist is
now picked up, which then breaks the build because it's not documented,
so add it to the sections file.
Based on patch by Víctor Manuel Jáquez Leal <vjaquez@igalia.com>.
Fixes#625862.
Adds a new tag to inform about the image orientation and how
to rotate and flip it before display.
Note that this tag is a string with a predefined set of
possible values.

This makes it possible to easily get a *:5 debug log without all
the refcounting noise, and drastically reduces the number of lines
output for a normal log (46m to 28m for a 20min video). The full log
including refcounting information can still be gotten using *:7.
Fixes#620460.
Adds 3 new geo location tags involving direction and
movement of capture. Those are:
API: GST_TAG_GEO_LOCATION_CAPTURE_DIRECTION

Adds those new tags to describe the device manufacturer and
model used to create medias.

Use .NOTPARALLEL when building docs. This avoids intermittent
make distcheck failures like 'cp: cannot create regular file
`build/image.entities': File exists' when using -jN.
Fixes#590718.
Adds a new tag for user favorite media rating.
User rating informs how much (from 0 to 100) a user
'likes' a media.
Having an percent uint range for this is easy to map into other scales,
like some players that allow users to attribute 'stars' to its
media.
API: GST_TAG_USER_RATING

Includes a tiny change of the GST_BOILERPLATE_FULL() macro:
The get_type() function is no longer declared before being defined.

The functions are called gst_byte_writer_put_{float32|float64}_*() and not
gst_byte_writer_put_{float|double}_*().

Adds a new function to GstByteWriter that writes
a constant value to a memory area (aka memset).
Useful for adding padding to buffers.
Also updates .def file and docs.
API: gst_byte_writer_fill()
gst_byte_writer_reset_and_get_buffer wasn't declared
in .h, instead there was _reset_and_get_data_as_buffer.
Replace it with the real function name, that is smaller
and matches gst_byte_writer_free_and_get_buffer

Fix link to gst-uninstalled now that it's been moved, and fix a typo
while we're at it. Also add a new section to 'Building GStreamer from
git' that points to the 'How do I develop against an uninstalled copy
of GStreamer' section.
Add a method to perform get_range typefinding that also uses the
uri/location extension as an extra hint. It will first try to call the
typefind functions of the factories that handle the given extension. The result
is that in the common case, we only call one typefind function, which speeds up
the typefinding a lot.
The only reason these two functions are still around is that at some
point in the past they were in a public header, so we can't really
remove them now even though they should have been private all along
(and aren't really particularly useful). Since these are just empty
stubs now that do nothing but return FALSE and will be removed in
0.11 anyway, we may just as well deprecate them formally.
Add a method to install a clipping function that is called when a buffer is
received. Users of collectpads can then perform clipping on the incomming
buffers.
Also retab the header file a little.
See #590265
Adds the following new tags:
GST_TAG_SHOW_NAME
GST_TAG_SHOW_SORTNAME
GST_TAG_SHOW_EPISODE_NUMBER
GST_TAG_SHOW_SEASON_NUMBER
GST_TAG_LYRICS
GST_TAG_COMPOSER_SORTNAME
GST_TAG_GROUPING

Mention that elements implementing GstMixer and GstTuner need to be
in the right state before they can be used. Also mention GLib
functions for converting filenames to and from URIs.
Fixes#602877.
gst_event_new_sink_message()
gst_event_parse_sink_message()
This event is used for sending a GstMessage downstream and synchronized
with the stream, to be posted by the sink once it reaches the sink.
Fixes bug #602275.
and install into a different directory $(libexecdir/gstreamer-0.10) so that
everything is versioned properly.
NOTE: run 'make clean' after updating; if you are running an uninstalled setup,
you will need to update your gst-uninstalled script (unless it's symlinked
to gstreamer core master) and exit/enter your uninstalled environment to get
the updated environment. If you are running an installed setup, you should
run 'make uninstall' before merging this change or remove the old
plugin-scanner binary manually.
Fixes#601698.
gst_util_greatest_common_divisor()
gst_util_double_to_fraction()
gst_util_fraction_to_double()
Using these instead of going over GValue has much lower overhead.
Also add float<->fraction transform functions for GValue.
This returns the internal feature list cookie, which changes every
time a feature is added or removed. This can be used by elements
to check if they should update their cached feature lists.
