4f0fc8a42c avvidenc: Make sure to pass always increasing PTS to the encoder
All MPEG1/2/4-based encoders at least are ignoring input frames if
backwards PTS or PTS that are equal to the previous one are passed in.

d871f34b39 libav: Update AVCodecContext lifetime to work properly with ffmpeg 7
avcodec_close() is deprecated and it's not supported anymore to re-open
a codec, so we only ever allocate the codec in set_format() now and
always free it after usage.

As part of this, also fix various memory leaks in related code paths.

bbf21060c2 avviddec: Rename variables and fuse function
* gst_ffmpegviddec_frame() is the only caller of gst_ffmpegviddec_video_frame()
  and has the same signature. Just move the checks into a single function and
  use that.
* Make it clear which frames are the input and output ones in
  gst_ffmpegviddec_video_frame() to make issues like the one fixed in the previous
  commit more obvious.

bd7b5b166d avdemux: Remove typefinder implementation
Direct access to AVInputFormat::read_probe() is not possible anymore
with ffmpeg 7.0, and the usefulness of this typefinder seems limited
anyway. An alternative implementation around av_probe_input_format3() or
similar would be possible but it would be going over all possible ffmpeg
probes at once.

Having a typefinder here means that basically every application will
load the gst-libav plugin when typefinding is necessary, which has
unnecessary performance impacts. If a typefinder from here was indeed
missing from typefindfunctions in gst-plugins-base then it would be
better to add it there directly.

765f8767ef avvidec: Fix dropping wrong "ghost" frames
This fixes the code regarding dropping "ghost frames", that is to say input
frames which ended up not producing any decoded frame.

The iteration itself makes sense.. but it was stopping at the "input" frame and
not the decoded frame we just got back.

When dealing with I-frame codecs, ffmpeg will decode frames in separate frames,
so there is no guarantee that they are decoding in order.

Fixes playback issues with such codecs

9048bea3d3 avcodecmap: Increase max AAC channels to 16
This is the maximum amount supported by aacenc. 8-channel output fully works.
16-channel also encodes fine, but codec-utils isn't able to parse its channel config,
so output level will not be shown in caps. For that to work, GASpecificConfig parsing
needs to be implemented. It's not a critical issue and can be worked on at a later date.

3f9665eed2 avviddec: Fix how we get back the codec frame
With the new copy_opaque system, the corresponding frame is stored in the
picture opaque ref.

This also handles the case where the "regular" opaque might be empty in the
case of "DECODE_ONLY" frames, since it that field is set in `get_buffer2()`
which might not be called for those frames

a1cbe351ec musepack: Prefer using FFmpeg musepack decoder/demuxer
* Bump the rank of the musepack v7/v8 FFmpeg demuxers to SECONDARY
* Bump the rank of the musepack v7/v8 FFmpeg audio decoders to SECONDARY
* Demote the rank of the musepackdec element to MARGINAL

This is for two reasons:
* The musepack library is no longer maintained, whereas the FFmpeg
  implementation can/will receive fixes
* The `musepackdec` implementation was a all-in-one "parsing and decoding" blob
  which doesn't play nicely with decodebin3 and others

6d94b77ae8 libav: expose fake booleans properties as enums
Some ffmpeg options claims to be booleans but are actually 3-values enums
with -1 as default instead of 1 or 0. Handle those using a custom enum
so we keep the same defaults as ffmpeg and users can properly configure them
if they need to.

See https://gitlab.freedesktop.org/gstreamer/gstreamer/-/issues/3035
for an actual example of this problem. The GStreamer element was
automatically enabling a non-default option, leading to strange behavior
in the AAC encoder.
