9738990542 Revert "avformat/hlsenc: compute video_keyframe_size after write keyframe"
This reverts commit b5ca8f2c66.

This commit will make new problem about tickets: 9193,9205
It flush data into file with init file context together,
and it can get keyframe size, maybe need more method to get keyframe
size.

07dec5b0c3 avcodec/utils: don't return negative values in av_get_audio_frame_duration()
In some extrme cases, like with adpcm_ms samples with an extremely high channel
count, get_audio_frame_duration() may return a negative frame duration value.
Don't propagate it, and instead return 0, signaling that a duration could not
be determined.

674adf0a02 avcodec/vc1dec: Disable error concealment for *IMAGE
The existing error concealment makes no sense for the image formats, they
use transformed source images which is different from keyframe + MC+difference
for which the error concealment is designed.
Of course feel free to re-enable this if you have a case where it works and
improves vissual results
