b77948d511 mpegts: make accidentally exported debug category symbol private
Was never in header files, was just exported by accident because
of the gst_ prefix of the variable name.

This increases the chances that we won't need to do any conversion
for a given pad.

388b7ee275 videoaggregator: improve find_best_format heuristic.
The goal here is to minimize the work needed to bring all images
to a common format. A better criteria than the number of pads
with a given format is the number of pixels with a given format.

4064683d36 adaptivedemux: Fix leak of pad probes in GstAdaptiveDemuxStream
This commit ensures that the idle probe which GstAdaptiveDemuxStream
adds to the upstream source pad is removed after use. Previously a new
probe was added to the pad whenever a fragment was downloaded, meaning
the number of pad probe callbacks being executed increased continually.

2ebcfcbc43 adaptivedemux: Stop prepared streams as well as running streams
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
current pads, and the other half are the pads that are about to be
switched to due to a bitrate change.
The old code only stopped the current streams which could result
in a deadlock on stopping the pipeline. The changes force stopping
and joining of any prepared streams too.

806ff70590 compositor: Add support for crossfade blending
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.

Some rationnal can be found in https://phabricator.freedesktop.org/T7773.

b89c94b37e gl: return NULL mem if eglCreateImage failed
Found on rpi when gpu_mem is too low so there is not enough memory to
create the eglimage. But still gst_buffer_pool_acquire_buffer succeeded.
And it leads to a CRITICAL assert:
  gst_egl_image_get_image: assertion 'GST_IS_EGL_IMAGE (image)' failed

7c3bfbb512 aggregator: Remove the GAP event from the queue before queueing up the GAP buffer
Otherwise check_events() will not remove the GAP event (as the queue
tail is not the event anymore but the GAP buffer), then the GAP buffer
is handled, then the GAP event is handled again, ... forever.

24e3cbf13b gl/cocoa: keep refs over async operations
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
window.  When the delayed operations execute, they then reference dead
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.

50f92fab89 adaptivedemux: Workaround for live seek ranges when advancing
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).

1df725e5cd adaptivedemux: Handle prepared streams on seeks
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.

6083ad6287 glfilter: Remove hard-coded pad templates
Add a function to install the default RGBA pad templates,
but don't make them required so that there can be
GstGLFilter sub-classes with different input/output
caps if they want. Remove the hard-coded RGBA restriction in
the set_caps_features call, as it will be taken care
of by intersecting with the pad templates.

Update all the sub-classes to match

8a070cf9af adaptivedemux: Allow application to force EOS
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.

When the pad has received EOS, its buffer may still be mixed

to the output framerate.

This was introduced by my patch in

also correctly addresses the initial issue.
