Bug 53908 – mplayer can't read avi index written by mencoder - 1GB ODML_CHUNKLEN problem

• Product: Gentoo Linux
• Status: RESOLVED DUPLICATE

[Description Honza 2004-06-14 11:37:27 UTC]

MPlayer (media-video/mplayer-1.0_pre4) can't read whole index of avi file written by mencoder (media-video/mplayer-1.0_pre4) if that avi file is over 1GB (ODML_CHUNKLEN) in size. It behave like only first 1GB is indexed, after that point no seeking is possible.

With -forceidx, index is regenerated and seeking works in whole avi.

Reproducible: Always
Steps to Reproduce:
1. Create avi file over 1GB using mencoder (for example, from Lord Of The Rings: Two Towers Special Edition).
2. Play it
3. Try to seek 1 minute before end.

Actual Results:  
It never cross the 1GB boundary using seek - it will seek to 1GB and do weird
things if it's not keyframe. You can play from it to end of movie, of course.

Expected Results:  
Seek in whole movie.

I think problem begin with adding ODML_CHUNKLEN test code to
libmpdemux/muxer_avi.c - mplayer 0.92 don't have anything like it and it can
generate avi files over 1GB and play them without problem.

Of course, I don't know if real bug is in libmpdemux/muxer_avi.c or if mencoder
generate right avi and bug is in libmpdemux/demux_avi.c which can't read them.
