8209ae476f avviddec: Temporarily unlock stream lock while flushing buffers
This can call into the decoder again from other threads and try to take
the stream lock from there, which would cause a deadlock.

07ba258ead avviddec: Drop decoder stream lock when calling send_packet
This is already done for every other calls to send_packet. The deadlock occures
since FFMPeg 6.0. The decoder tries to get a buffer from a thread during
the draining process, and blocks trying to get the video decoder stream lock
already heald by the drain function.

Fixes #2383

f1bc3e6d88 ffmpeg: avauddec/avviddec: Free packet side data after usage
As we don't use proper refcounting with AVPacket we have to manage this
ourselves.

cde31d23c0 avviddec: change AV_CODEC_CAP_AUTO_THREADS->AV_CODEC_CAP_OTHER_THREADS
This fixes a compile error with recent upstream FFmpeg.

The AV_CODEC_CAP_AUTO_THREADS was deprecated and renamed to
AV_CODEC_CAP_OTHER_THREADS in FFmpeg upstream commit
7d09579190de (lavc 58.132.100).

The AV_CODEC_CAP_AUTO_THREADS was finally removed in FFmpeg upstream
commit 10c9a0874cb3 (lavc 59.63.100).

1cbb145c50 avviddec: Disable AV1 decoder
We have various elements for AV1 decoding, the ffmpeg one only works if
hardware support is available and seems to require special signalling.

090cf943ed avviddec: Report flow error when decoder refused packet
In cases where an invalid input packet is submitted to the decoder we emit a
warning but reporting the flow error upstream would also be useful. This came up
with a case were the application interacts directly with the decoder, using a
mechanism similar to GstHarness.

c39400b52c avviddec: Report a latency even without upstream framerate
There are cases where upstream will not provide a framerate, or it won't be
fixed. But if there is latency introduced by the decoder we do want to report
it.

Therefore use the framerate stored in the actual decoder, which will have a
default.

Fixes hangs when playing back such streams with decodebin3 (where the multiqueue
will not have been informed of that downstream latency and not grow accordingly)

5c2eba666b avdec_h265: Fix endless renegoation with alternate interlacing
The picture parameter picture->top_field_first is reused in this mode
to signal the TOP fields. As a side effect, it will change every frame
and current code assumed that if this changes then a renegotiation is
needed. Fixed this by ignoring that change whenever we are decoding one field
only.

9ebe338d80 avviddec: Avoid flushing on framerate changes
A framerate change does not require flushing the decoder and causes
issues with some specific fragmented files if the two fragments have
different framerate.

b90d02741e avviddec, video.c, h265parse: Workaround for broken field-based interlaced encoders
Some encoders (e.g. Makito) have H265 field-based interlacing, but then
also specify an 1:2 pixel aspect ratio. That makes it kind-of work with
decoders that don't properly support field-based decoding, but makes us
end up with the wrong aspect ratio if we implement everything properly.
As a workaround, detect 1:2 pixel aspect ratio for field-based
interlacing, and check if making that 1:1 would make the new display
aspect ratio common. In that case, we override it with 1:1.

be1b31b5f8 avviddec: Remove vc1/wmv3 override
FFMPEG 5+ doesn't allow overriding the codec anymore (causes a segfault if you
attempt to do that). But the best part is ... that with the current caps
implementation in pad template and gst_ffmpeg_caps_to_codecid() we would never
replace it by anything different than the existing codec id.

6ea56e7fd3 gst-libav: fix build with ffmpeg-5.0.0
Latest ffmpeg has removed avcodec_get_context_defaults(), and its
documentation says a new AVCodecContext should be allocated for this
purpose.  The pointer returned by avcodec_find_decoder() is now
const-qualified so we also need to adjust for it.  And, AVCOL_RANGE_MPEG
is now rejected with strict_std_compliance > FF_COMPLIANCE_UNOFFICIAL.
