It's almost a fork of glwindow_win32 implementation.
To build on Windows, Vulkan SDK (at https://vulkan.lunarg.com/sdk/home)
and VK_SDK_PATH environment are required. Note that VK_SDK_PATH environment
setting is a part of the SDK installation.
Limitations:
- No transport changes at all (ICE, DTLS)
- Codec changes are untested and probably don't work
- Stream removal doesn't remove transports (i.e. non-bundled transports
will stay around until webrtcbin is shutdown)
- Unified Plan SDP only. No Plan-B support.
Having the opencv feature enabled would lead to the opencv3 dependency
being required which failed with only opencv4 being available.
Instead don't require anything and error out at the end if the feature was enabled
but no dependency was found.

This is the equivalent of iceTransportPolicy in the RTCConfiguration
dictionary.
Only two values are implemented:
* all: default behaviour
* relay: only gather relay candidates
The third member of the iceTransportPolicy enum, "public", is
obsolete.
* Add FIXME for future correction of HRDParames parsing.
Spec. defines that the number of HRDParames could be up to
"vps_num_layer_sets_minus1 + 1" (i.e., 1024).
* Add parsing vps_base_layer_{internal,available}_flag.
* Fix possible invalid vps_extension parsing.
Fixes#798
Otherwise setting an URI after creation will already set the state

For each lib we build export its own API in headers when we're
building it, otherwise import the API from the headers.
This fixes linker warnings on Windows when building with MSVC.
The problem was that we had defined all GST_*_API decorators
unconditionally to GST_EXPORT. This was intentional and only
supposed to be temporary, but caused linker warnings because
we tell the linker that we want to export all symbols even
those from externall DLLs, and when the linker notices that
they were in external DLLS and not present locally it warns.
What we need to do when building each library is: export
the library's own symbols and import all other symbols. To
this end we define e.g. BUILDING_GST_FOO and then we define
the GST_FOO_API decorator either to export or to import
symbols depending on whether BUILDING_GST_FOO is set or not.
That way external users of each library API automatically
get the import.
While we're at it, add new GST_API_EXPORT in config.h and use
that for GST_*_API decorators instead of GST_EXPORT.
The right export define depends on the toolchain and whether
we're using -fvisibility=hidden or not, so it's better to set it
to the right thing directly than hard-coding a compiler whitelist
in the public header.
We put the export define into config.h instead of passing it via the
command line to the compiler because it might contain spaces and brackets
and in the autotools scenario we'd have to pass that through multiple
layers of plumbing and Makefile/shell escaping and we're just not going
to be *that* lucky.
The export define is only used if we're compiling our lib, not by external
users of the lib headers, so it's not a problem to put it into config.h
Also, this means all .c files of libs need to include config.h
to get the export marker defined, so fix up a few that didn't
include config.h.
This commit depends on a common submodule commit that makes gst-glib-gen.mak
add an #include "config.h" to generated enum/marshal .c files for the
autotools build.

This moves all the conversion related code to a single place, allows
less code-duplication inside compositor and makes the glmixer code less
awkward. It's also the same pattern as used by GstAudioAggregator.
This is only used for caching reasons and should never actually be in
the public API. If this is ever a bottleneck later, caching around a
class private struct could be implemented.

intersected with the connected sink pads/attached transceivers as in
the case for creating an answer. In both cases, the rtp payloaded streams
sent by the peer are exposed as separate src pads.

According to the vp8 spec, the first partition (size can be derived from
the frame header) should have all compressed header information and we
implemented gst codecparser based on that. But it doesn't seem to be the

When switching bitrates we set the old streams as cancelled, but it
could also be confused with a cancel due to other reasons (as an error)

update on live. Ss make it sure that we are stopping for switching
bitrates to avoid erroring out.

Add a comment for when the state matters. Use a local var for priv in

We want to skip serialization for FLUSH_STOP events (apparently). We can
simplify the code to add it to the top-level conditions. There was nothing
done in the first code path if the event was FLUSH_STOP.
Just queue it like any other serialized event. This way we don't need to
check if there still are buffers in the queue.
Validated with the tests and gst-launch-1.0 pipelines.
Don't reuse the offset variables will contain a sample offset for an
intermediate time value. Instead add a segment_pos variable of type
GstClockTime for this. Use The clock-time macros to check if we got
a valid time.
Acording to the logic this cannot happen (we already check this before). So
add a assert like we do above and remove the check. This make it clearer that
we check for the offset range.
Also remove a dead assignment since we reassign this a few lines below.
Don't copy the whole event struct. Set the input params when we call the
forwarding helper. Initialize the internal fields and return values in the
helper.
This simplifies the code a lot without any functional changes apart from
not closing the display connection. Closing the display connection is
not safe to do as it is shared between all other code in the same
process and no reference counting or anything happens at the platform
layer.
1. Propagate the GstGLDisplay we create

Except for gst/gl/gstglfuncs.h
It is up to the client app to include these headers.
It is coherent with the fact that gstreamer-gl.pc does not
require any egl.pc/gles.pc. I.e. it is the responsability
of the app to search these headers within its build setup.
For example gstreamer-vaapi includes explicitly EGL/egl.h
and search for it in its configure.ac.
For example with this patch, if an app includes the headers
gst/gl/egl/gstglcontext_egl.h
gst/gl/egl/gstgldisplay_egl.h
gst/gl/egl/gstglmemoryegl.h
it will *no longer* automatically include EGL/egl.h and GLES2/gl2.h.
Which is good because the app might want to use the gstgl api only
without the need to bother about gl headers.

There can be twice as many stream tasks running as there are output
pads for playback of variant HLS playlists. Half of them are the

Crossfading is a bit more complex than just having two pads with the
right keyframes as the blending is not exactly the same.
The difference is in the way we compute the alpha channel, in the case
of crossfading, we have to compute an additive operation between
the destination and the source (factored by the alpha property of both
the input pad alpha property and the crossfading ratio) basically so
that the crossfade result of 2 opaque frames is also fully opaque at any
time in the crossfading process, avoid bleeding through the layer
blending.

Avoids dereferencing dead objects
What happens in the autovideosink case is that context 1 is created and
destroyed before all the async operations hae executed on the associated

objects and crash.
We fix this by keeping refs over all async operations so the object
cannot be deleted while async operations are in flight.

This is a workaround for a regression introduced by
f4190a49c0
( adaptivedemux: Check live seeking range more often )
The goal of the previous commit was to be able to cope with non-1.0
rates on live streams which have a "seeking window" (i.e. the server
keeps around quite a bit of the live stream so you can seek back into
it).
Without that commit, two different kind of issues would happen:
* When doing reverse playback, you would never check whether you
are outside of the seekable region. And would then continuously
try to download fragments that are no longer present.
* When doing fast forward, you would end up requesting fragments
which are not present yet.
In order to determine whether one was *really* outside of the seekable
window, we check whether the current stream position is still
within the seekable region.
The *problem* though with that commit is that it assumes that subclasses
will return continuously updated seeking ranges (i.e. dependent on the
current time), which is *NOT* the case.
For example:
* dashdemux does use the current UTC to determine the seekable region
* hlsdemux uses the values from the last updated manifest
Therefore if one downloads fragments faster than realtime, for HLS
we would end up at the end of the last manifest seekable range, and
the previous commit would consider the stream as being ended... which
is not the case.
In the long run, we need to figure out a way to cope with non-1.0
rates on live streams for all types of stream (including HLS).

This is a race that was exposed by the {hls|dash}.scrub_forward_seeking
validate test.
The "race" is that a subclass might want to change format, causing
a new stream to be created (but not exposed/switched yet) and put on the
prepared_streams list. That stream will have values (including pending
segment) from the pre-seek state.
Before the stream is exposed/switched, a new seek comes in and the stream
values get updated ... but the ones that will be changed don't get updated
causing them to push out wrong segments once they are exposed.

Adaptive demuxers are special demuxers that runs their own sources
internally. In this patch we flag the demuxer as being a source in order
to receive the downstream events. We then handle the EOS event by
resetting the internal state and pushing EOS on all pads. This handling
is done asynchronously to avoid blocking user thread.
https://bugzilla.gnome.org/show_bug.cgi?id=723868

any number of times, when the pad's framerate is inferior

We have to pass the "height" as height = vmeta->offset[1] / width to the
API, which of course does not work well for formats with only a single
plane. Use the whole memory size instead of the offset in that case.
Previous commit let demux call gst_uri_downloader_cancel() on _demux_reset().
Note that, _demux_reset() called during PAUSED_TO_READY and READY_TO_PAUSED.
And, it will set "cancelled" on uridownloader which blocks the use of
uridownloader. The issue is that, subclass can use the uridownloader not only
live streaming for manifest update, but also for fetching another manifests
such as variant and rendition m3u8 of hls streaming. So to unblock it,
demux should clear "cancelled" before processing initial manifest.

before broadcasting preroll.
The deadlock was as follows:
-> The subclass pushes a buffer on a newly-created stream in T1
-> We take the preroll lock in T1, to handle_preroll
-> The demuxer is stopped in T2, we take the MANIFEST_LOCK
-> T1 starts blocking because it received a reconfigure event
and needs to take the MANIFEST_LOCK
-> T2 deadlocks because it now wants the preroll_lock.

The live seeking range was only checked when doing actual seeks. This was
assuming that the rate would always be 1.0 (i.e. the playback would
advance in realtime, and therefore fragments would always be available
since the seeking window moves at the same rate).
With non-1.0 rates, this no longer becomes valid, and therefore we need
to check whether we are still within the live seeking range when advancing.

What we want is to retry downloading the fragment on 4xx/5xx errors

This ensures that they really get processed in order with
buffers. Just waiting for the queue to be empty is sometimes not
enough as the buffers are dropped from the pad before the result is
pushed to the next element, sometimes resulting in surprising
re-ordering.
In the case an aggregator is created and pads are requested but only
linked later, we end up never updating the upstream latency.
This was because latency queries on pads that are not linked succeed,
so we never did a new query once a live source has been linked, so the
thread was never started.
https://bugzilla.gnome.org/show_bug.cgi?id=757548
When caps changes while streaming, the new caps was getting processed
immediately in videoaggregator, but the next buffer in the queue that
corresponds to this new caps was not necessarily being used immediately,
which resulted sometimes in using an old buffer with new caps. Of course
there used to be a separate buffer_vinfo for mapping the buffer with its
own caps, but in compositor the GstVideoConverter was still using wrong
info and resulted in invalid reads and corrupt output.
This approach here is more safe. We delay using the new caps
until we actually select the next buffer in the queue for use.
This way we also eliminate the need for buffer_vinfo, since the
pad->info is always in sync with the format of the selected buffer.

This commit fixes the following assumptions with live seeking:

2) direction was always forward
3) stop should be offsetted when handling non-accurate seeks before
the range start position.
In order to handle more live seeking use-cases (including reverse playback),
only do non-accurate start/stop value clamping for GST_SEEK_TYPE_SET values.
Also add a bit more debugging lines for issues

When dealing with live streams, we can't rely on GstSegment calculation
since it uses the segment duration to calculate the absolute values.
But since we are dealing with live *and* we know the ranges, we can
compute the absolute seeking values using the range stop (i.e. "now")
as the END position.
Allows seeking back to "live" by using start_type:GST_SEEK_TYPE_END
and start:0
https://bugzilla.gnome.org/show_bug.cgi?id=782228
The allowed live seek ranges returned by subclasses are "inclusive", that is
to say that the "range_stop" value they return is the highest acceptable position
one can seek to (i.e. "now").
Allow seeking to exactly that value
Rationale is to allow the manifest update task to continue running while
seeks are occurring. Otherwise, if the user reliably performs a seek
before the manifest is updated, then as the manifest task is reset on
seeks (and thus the time to wait between manifest updates), the manifest
would never be updated.
This fix makes the manifest update task free-running and continously
update even during seeks.
Some actions (Qos, reconfigure, ...) might take place before we finish pushing out flush_start.
One problem would be that:
1) The QOS handling in adaptivedemux takes the MANIFEST LOCK
That QOS event comes from basesink with its PREROLL_LOCK taken
2) FLUSH_START is sent from adaptivedemux with the MANIFEST_LOCK taken and the basesink flushing handler needs to take the PREROLL_LOCK
=> deadlock

of fragment was advanced already. So, checking stream_has_next_fragment()
means looking for the next fragment of target fragment.
This might cause unexpected buffering if each fragment has
large duration and manifest is listing only limited number of fragments.

The GstGLFramebufferClass struct is typedeffed in
gstgl_fwd.h, and having a duplicate elsewhere is
breaking the cerbero build on my OSX machine,
even though it seems to be working in CI.
When entering this code path, we know that:
We received EOS on this pad.
We consumed all its buffers.
In any case, we want to replace vaggpad->buffer with NULL,
otherwise we will end up mixing the same buffer twice.

If set, the parent is used to proxy need-context messages from
uridownloader's http source in order to get cookies/headers
from the pipeline.

When there are new pads pending for a bitrate switch, don't allow
EOS through from the old streams. It will be sent when the new pads are
ready, just before the old streams are removed.
This fixes racy bitrate switching with hlsdemux in urisourcebin
where old pads EOS before new pads appear and the entire pipeline can
EOS if those propagate fast enough
libgstgl has a dependency on libgstallocators starting with:
ed1e4c1 glupload: Add support for Vivante DirectTexture uploads
The dependency wasn't stated in the Makefile, so the build could
occasionally fail if you got unlucky with the ordering of build
steps.

In commit
> 956c4d0 gl/format: use our own GL format enum's instead of gstvideo's
the name and return type of gst_gl_format_from_video_info changed,
but some returns of the old type were missed. Here they are
updated to the correct type.

gst_player_set_uri_internal shouldn't free suburi which maybe set
by user to load external subtitle before start play. It just need
reset playbin's subutri property to NULL no matter if there was a
previous one or not.

All code interacting with Objective-C objects should now use Automated
Reference Counting rather than manual memory management or Garbage
Collection. Because ARC prohibits C-structs from containing
references to Objective-C objects, all such fields are now typed
'gpointer'. Setting and gettings Objective-C fields on such a
struct now uses explicit __bridge_* calls to tell ARC about
object lifetimes.

For duration queries on live streams, adaptivedemux ignores the query.
The problem then is that the query is answered by the downstream
qtdemux element, with the duration of the currently passing fragment.
This commit changes the behaviour of adaptivedemux to answer the duration
queries for live streams, returning GST_CLOCK_TIME_NONE.

If we need to send EOS on a pad that hasn't prerolled, generate
an error on the bus instead, otherwise the app will have no idea.
Fixes the HLS testFragmentNotFound test, which is waiting
for either EOS or an error.
To ensure that pads have caps when they are exposed, do
the exposing when all pending streams have prerolled an
output buffer, and only then EOS and remove any old pads.
Improves the switching sequence by making caps available
as soon as a pad appears.

send_event() of parent class (i.e., GstBinClass) iterates srcpads
to send SEEK event. And performing it per srcpad is inefficient.
So, let's drop duplicated SEEK event by checking seqnum

- Add overlay video renderer "video-sink" property, so that can be set
- In create_video_sink, it returns video sink instead of always NULL
- Add new renderer_new_with_sink() API to set video sink
