f7337b7477 ffmpeg: Don't register elements for which we have no caps 
We would previously register a whole bunch of encoder/decoder for which the caps
were ... "unknown/unknown".

Add a function to quickly check (without generating caps) whether a given
AVCodecID has a known mapping (which can include the {video|audio}/x-gst-av-*
ones) without generating the caps.

e52f0bbc03 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.

73d0cac16c 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.

13fc49770e avvidenc: Don't take ffmpeg timestamps verbatim but only use them to calculate DTS 
The ffmpeg timestamps are inaccurate and only in framerate granularity.
To avoid generating inaccurate output timestamps, especially with
variable framerate streams, only use the ffmpeg timestamps for
calculating the DTS.

5372b77987 Revert "avvidenc: Set timebase in the ffmpeg context to nanoseconds and set framerate" 
This reverts commit 50db59449e.

This broke the MPEG-1 video encoder as it requires the framerate to be
used for the timebase.

Otherwise ffmpeg's rate control algorithm will not work correctly as
it is based on the absolute PTS values.

50db59449e avvidenc: Set timebase in the ffmpeg context to nanoseconds and set framerate 
As we now actually use the timestamps from ffmpeg for timestamping the
output we would lose a lot of accuracy if the framerate is used.

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.
