17aca8a8c2 avviddec: Enable subframe decoding for H.264 
Enable sending NAL units to the decoder without having to first
group them in a frame (an AU).

81cbd0deb6 avviddec: Split allocation tracking from decode-only-ness 
When doing subframe decoding, handle_frame will be called multiple
times, so the DECODE_ONLY flag gets re-set when it shouldn't. Instead,
let's create our own flag to track this.

dcea8baa14 avcodecmap: Don't try converting channel layouts with more than 64 channels 
We only support up to 64 channels in GStreamer with a specific layout so
it's safe to assume a NONE layout in this case.

Also the arrays of channel positions are allocated everywhere with 64
elements so don't try setting more than 64 to NONE as that will cause
stack corruptions and similar memory safety issues.

Thanks to Natalie Silvanovich for reporting this issue.

1d33d1c8ea avviddec: take the maximum of the height/coded_height 
Otherwise, some h.264 streams (particularly with cropping information)
may cause memory corruption after a renegotiation to a smaller size when
decoded and then ffmpeg writes past the end of the buffer.

f166c9d234 viddec: don't configure and incorrect buffer pool when receiving a gap event 
Scenario is this:
1. libav receives enough data to want a buffer with get_buffer2()
   which wants a buffer pool with a certain format, say Y42B but does
   not negotiate and therefore GstVideoDecoder does not have any output
   state configured
2. A gap event is received which GstVideoDecoder wants to forward.  It
   needs caps to forward the gap event so attempts to negotiate with some
   default information which chooses e.g. I420 and overwrites the
   previously configured bufferpool decided on by get_buffer2()
3. There is a mismatch between what ensure_internal_pool() check for
   consistency and what decide_allocation() sets when overriding the
   internal pool with the downstream pool.
4. FFMpeg then requests a Y42B buffer from an I420 pool and predictably
   crashes writing past the contents of the buffer

This is fixed by keeping track of the internal pool states correctly.

b6acd99239 avauddec: Check planar-ness of frame rather than context 
The check seems to be to present to verify that the decoded frame
matches the format we expect. The actual check for the layout of the
frame was being performed against the context instead.

The check fails at least for avdec_aptx_hd, where the AVCodecContext has
the sample format set to AV_SAMPLE_FMT_NONE.

89bb244ab9 avaudenc/avvidenc: Reopen encoding session if it's required 
Since the commit https://git.ffmpeg.org/gitweb/ffmpeg.git/commit/22b25b3ea5c,
ffmpeg will not clear draning flag for encoder by avcodec_flush_buffers() API
by default. Allowed case is only if encoder has AV_CODEC_CAP_ENCODER_FLUSH
capability flag. If it's not supported, we should re-open encoding
session, otherwise ffmpeg encoder will keep returning AVERROR_EOF

c6e51f404d avauddec: Avoid dropping non-OK flow return

83190c4ec0 gstavviddec: Only allow a single closed caption meta 
Following discussion in
https://gitlab.freedesktop.org/gstreamer/gst-plugins-bad/-/merge_requests/1396#note_556068

While it is technically possible to store multiple closed caption metas
in the same buffer, we don't currently do that anywhere and for
H264/MPEG2 both parts have to be stored in the same packet, and also the
number of CC bytes you can store per frame is rather limited. This
restriction might be relaxed later once we figured out how to do it
without breaking things.
