bac4bb747a avformat/matroskadec: Reset state also on failure in matroska_reset_status()
The calling code does not handle failures and will fail with assertion failures later.
Seeking can always fail even when the position was previously read.

Fixes: Assertion failure

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.

'buf' is  part of  'AVPacket pkt'.
replace init_get_bits with init_get_bits8.
