	  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.

	* ext/libav/gstavviddec.c:
	  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.

	* ext/libav/gstavviddec.c:
	  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.

	  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.

	  While it is technically possible to store multiple closed caption metas

	  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.

	* ext/libav/gstavviddec.c:
	  gstavviddec: Limit default number of decoder threads
	  When the `max-threads` property is not specified, GStreamer defaults to
	  the amount of CPU threads in the system.
	  The number of threads used in avdec has a direct impact on the latency
	  of the decoder, which is of as many frames as threads. Therefore, big
	  numbers of threads can make latency levels that can be problematic in
	  some applications.
	  For this reason, ffmpeg emits a warning when more than 16 threads are
	  requested.
	  This patch limits the default number of threads to 16. This affects only
	  computers with more than 16 CPU threads when using avviddec without
	  setting `max-threads`.

	  Additionally, we need in that case to calculate the automatic

	  Since we now support non-interleaved audio, we can't
	  just concat buffers any more. Also, audio metas won't
	  be combined when buffers are merged, so when we push
	  out the combined buffer we'll look at the meta describing
	  only the first subframe and think it covers the whole
	  frame leading to stutter/gaps in the output.
	  We could fix this by copying the output data into a new
	  buffer when we merge buffers, but that's suboptimal, so
	  let's add some API to GstAudioDecoder to push out subframes
	  and use that instead.
