Comment (by ubitux):
{{{avformat_seek_file()}}} has an almost unused flag called
{{{AVSEEK_FLAG_FRAME}}} that could be used for this purpose if implemented
properly. Subtitles use that (see {{{ff_subtitles_queue_seek()}}}) because
they actually have a complete index. Assuming we do an index-pass, that
might be realizable with some demuxers supporting the load of that index.
Note that your proposed method would work only if 1 packet = 1 video
frame, which AFAIK is not always true.
