96eb5ef33c amcvideodec: Don't require a non-zero buffer size when doing decoding to a surface
At least on some devices/Android versions the buffer size will always be zero
in these cases.

3d5a1ccbf4 applemedia: vtdec: fix negotiation more
Year 12: I still don't understand how negotiation works.

Apparently gst_pad_query_caps doesn't do what I thought it did. To get the
actual caps that can flow through vtdec:src we must call gst_pad_peer_query_caps
with the template caps as filter.

Fixes negotiation with stuff that doesn't understand GLMemory (hello videoscale).

f2ca0eaf27 amcviddec: output external-oes textures
This provides a performance and power usage improvement by removing
the texture copy from an OES texture to 2D texture.

The flow is as follows
1. Generate the output buffer with the required sync meta with the incrementing
   push counter and OES GL memory
1.1 release_output_buffer (buf, render=true) and push downstream
2. Downstream waits for on the sync meta (timed wait) or drops the frame (no wait)
2.1 Timed wait for the frame number to reach the number of frame callbacks fired
2.2 Unconditionally update the image when the wait completes (success or fail).
    Sets the affine transformation matrix meta on the buffer.
3. Downstream renders as usual.

At *some* point through this the on_frame_callback may or may not fire.  If it
does fire, we can finish waiting early and render. Otherwise we have to
wait for a timeout to occur which may cause more buffers to be pused into the
internal GL queue which siginificantly decreases the chances of the
on_frame_callback to fire again.  This is because the frame callback only occurs
when the internal GL queue changes state from empty to non-empty.

Because there is no way to reliably correlate between the number of buffers
pushed and the number of frame callbacks received, there are a number of
workarounds in place.
1. We self-increment the ready counter when it falls behind the push counter
2. Time based waits as the frame callback may not be fired for a certain frame.
3. It is assumed that the device can render at speed or performs some QoS of
   the interal GL queue (which may not match the GStreamer QoS).

It holds that we call SurfaceTexture::updateTexImage for each buffer pushed
downstream however there's no guarentee that updateTexImage will result in
the exact next frame (it could skip or duplicate) so synchronization is not
guaranteed to be accurate although it seems to be close enough to be unable
to discern visually.  This has not changed from before this patch.  The current
requirement for synchronization is that updateTexImage is called at the point in
time when the buffers is to be rendered.

119e09eac3 applemedia: vtdec: improve negotiation
Rework negotiation implementing GstVideoDecoder::negotiate. Make it possible to
switch texture sharing on and off at runtime. Useful to (eventually) turn
texture sharing on in pipelines where glimagesink is linked only after
decoding has already started (for example OWR).

8f14882b44 applemedia: vtdec: improve handing of decode errors/frame drops
Improve decode error handling by avoiding calling into GstVideoDecoder from the
VT decode callback. This removes contention on the GST_VIDEO_DECODER_STREAM_LOCK
which used to make the decode callback slow enough for VT to start dropping lots
of frames once the first frame was dropped.

1491d02c4e adaptivedemux: remove now-defunct "num-lookback-fragments" property
This no longer does anything, and it was marked as CONSTRUCT_ONLY
which means someone would really have to go out of their way to
be able to set this, which would only be done in very custom
scenarios, if ever, and those will likely target a specific
version of GStreamer then, so probably not much point keeping
it deprecated for a while before removing it.
