Badly interleaved AVI file not handled

Reported by: ubitux Owned by:
Priority: normal Component: avformat
Version: git-master Keywords: avi,interleaved
Cc: nfxjfg@… Blocked By:
Blocking: Reproduced by developer: yes
Analyzed by developer: no

Description

The broken file is available at streams.videolan.org/issues/ffmpeg/yet-another-broken-interleaved-avi.avi.

The file seems correctly interleaved, but around 01:08, only video packets seems to be decoded. While MPlayer AVI demuxer is able to handle it ("Badly interleaved AVI file detected - switching to -ni mode..."), FFmpeg AVI demuxer doesn't.

  • Status changed from new to open

  • Component changed from avformat to undetermined
  • Reproduced by developer set

Works fine with ffmpeg and mplayer -demuxer avi, fails with ffplay and mplayer -demuxer lavf.

Too many video packets in the buffer: (4096 in 21598698 bytes).
Maybe you are playing a non-interleaved stream/file or the codec failed?
For AVI files, try to force non-interleaved mode with the -ni option.

Broken again, with the same sample. I do not know when it regressed.

Since it works fine here, could one of you add a command line that allows to reproduce the problem together with complete, uncut console output?

That's about 50 seconds in. A-V difference keeps getting worse from this point. The ALSA warnings are merely because ffplay doesn't feed it enough audio, and not a problem with my audio setup. File is linked in the top post.

So what's the difference? How to proceed? Just to be sure, I made a clean build of ffmpeg with no additional config option. Output with -loglevel debug:

Could you confirm the md5sum?

comment:10 Changed 7 months ago by gjdfgh

My test file was cut short (I probably wanted to save some space...). You can create a test file with:

dd if=yet-another-broken-interleaved-avi.avi of=test.avi bs=1048576 count=200

Note that this is almost the full file. md5sum: 96accaf5878be60f076a50038f85339c

mplayer -demux avi handles this fine (even without -idx, although it requires -idx for seeking), ffplay doesn't.

Shall I create a new ticket for this problem, or can I leave this ticket open?
