Vivia Nikolaidou 88fa030ab1 avviddec: Fix typo that duplicated closed caption meta 
We examined the output buffer, instead of the input buffer, for
existence of cc meta.

Vivia Nikolaidou 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.

Mathieu Duponchelle a5850215ba avdemux: update the context we use to determine stream's caps 
The discovered frame rate is only available on the AVStream
itself. Updating the temporary context framerate before
building caps from it seems like a pretty non-intrusive approach.

Alicia Boya García b7d450b118 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`.

Seungha Yang 80c8c05457 avviddec: Enforce allocate new AVFrame per input frame 
... if ffmpeg would reuse the allocated AVBuffer. Reused AVFrame by
the ffmpeg seems to break our decoding flow since the reused AVFrame
holds the initial opaque data (GstVideoCodecFrame in this case), so
we couldn't trace the our in/out frames.
To enforce get_buffer() call per output frame, hold another reference
to the AVBuffer in order to mark the AVBuffer as not writable.

Mathieu Duponchelle 1e8e040fbc avviddec: improve latency calculation 
When thread_type is set to FF_THREAD_FRAME, per the documentation
a latency of one frame per thread is introduced:

<https://ffmpeg.org/ffmpeg-codecs.html>, search for thread_type.

Additionally, we need in that case to calculate the automatic
number of threads ourselves, so as to accurately calculate the
latency.

Seungha Yang e8f21b510a avviddec: Add thread-type property 
The thread-type property allows specifying preferred
multithreading methods by user. Note that FF_THREAD_FRAME
may introduce additional latency especially on non-filesrc usecase,
since it introduces a decoding delay of (number of threads) frames.
