Does decoding bug happens with ffmpeg too?

Without sample there is no way to reproduce problem or way to fix it.

Do you mean if I try to play the transcoded .avi file with ffplay? I did not try ffplay since I assumed VLC decodes the file the same way. I can try that tomorrow when I get to work.

Is there a way to get a sample to you? This seems to happen with all "hi def" files found on this hard drive, so they are all big.

Is there any other log I can send you that is more complete that might help?

Replying to cehoyos:

You can upload a sample either to http://www1.datafilehost.com/ or read http://ffmpeg.org/bugreports.html

Okay, I've put the entire file in ffmpeg's incoming ftp. I think I got the text file in there but I'm not sure.

I tried playing the FFV1 AVI file with ffplay and got the same behavior. I also tried truncating with dd and the output file would not open.

I'm still not sure what you mean by "bug happens with ffmpeg." If you can clarify I'll try that too. Thanks.

Gahh. Okay, that'll teach me to use something other than filezilla. The file is 133 MB so datafilehost wouldn't take it. File should be up now. Filezilla reported a successful transfer.

Could you test vlc --rate=0.3 test.avi ?
(Yes, we should have realised this without a sample.)

Yes, that fixes the hang, but the video plays slower than it should. Does this mean I should encoded at a lower bitrate?

Your hardware is not fast enough to play your video on realtime (with vlc) ;-(
FFV1 is more for archivation than distribution for playback so decoding performance was not the primary goal. That said, a change has been committed to FFmpeg that improves playback on multicore systems considerably, so once the change hits vlc, it may work for you (but there is no guarantee).

Thanks, This is for archival purposes, so there will be access copies. I just wanted to be sure there wasn't something wrong with the encode. Thanks for your help.
