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.

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.

avvidenc: Offset PTS to zero to fix bitrate control
...
Otherwise ffmpeg's rate control algorithm will not work correctly as
it is based on the absolute PTS values.

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.

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.
