We need to improve the seeking
capabilities (performance) in our video player.
The video player concurrently
different video files (MP4),
and plays them
in a time synchronized manner.
Each video file has a time
index file (proprietary)
among other things a time stamp and
the corresponding byte position of the H.
264 data (I frame).
seeking is not an option due to performance reasons.
The same player can
file. They come with a video
time index file as well.
We have amazing results with bytes-wise seeking
It seems that the mpegtsraw demuxer (libavformat/mpegts.c) is
story with the mov demuxer:
To me it looks that the current implementation of
libavformat/mov.c does not support byte-
Having a look into the mov.c confirms my impression.
a possibility that this feature will be
the mov demuxer any time soon?
Thanks and best regards,
