Description

Summary of the bug:
Hi,

I'm trying to split VOB files cleanly with ffmpeg-2.1.1/Linux (32bit), using -f segment. My goal is to encode the resulting files in parallel on a cluster of machines, before merging everything back.

My understanding is that -f segment should create a new output file every time there's a key frame in the stream. However, I'm getting:

Assertion nus->keyframe_pts[k] > last_pts failed at libavformat/nutenc.c:596

The failed assertion is there:

            ff_put_v(bc, 1 + 2*flag + 4*n);
            for (k= j - n; k<=j && k<nut->sp_count; k++) {
                if (nus->keyframe_pts[k] == AV_NOPTS_VALUE)
                    continue;
=>              av_assert0(nus->keyframe_pts[k] > last_pts);
                ff_put_v(bc, nus->keyframe_pts[k] - last_pts);
                last_pts = nus->keyframe_pts[k];
            }

The command I ran was:

  ffmpeg -report -i concat:$(echo VTS_01*.VOB | tr ' ' \|) -map 0:1 -map 0:13 -codec copy -f segment output-%08d.nut

Full report attached.

Is the problem also reproducible with current FFmpeg git head?

comment:2 by ob, 11 years ago

I just tested, and yes. I'll attach this report too.

comment:3 by Carl Eugen Hoyos, 11 years ago

Is the concat filter required to reproduce the problem? Does it also happen if you only copy audio or only video (with -an or -vn)? Are specific samples needed?

comment:4 by ob, 11 years ago

Apparently it all works fine if I try without concat.

-an and -vn stop on the first file with this message:

Output file #0 does not contain any stream

The stream ids are changing between VOBs, which is likely an issue. Here's ffprobe output for all of them:

As for the samples, I'm not legally allowed to share them (I guess that's a common issue for you guys). Are some test samples available somewhere so I can reproduce with something you can use too?

I suspect that's all because of the changing stream ids but I'm not sure how to work around this. If I process each VOB separately without concat, will I lose audio and/or video continuity?

Actually, interestingly enough, it fails if I specify only the first VOB file and the video stream:

Actually, interestingly enough, it fails if I specify only the first VOB file and the video stream:

Please cut the sample as small as possible to still reproduce the issue and upload it.

comment:7 by ob, 11 years ago

What method do you prefer for me to cut it? dd with a block size of 2048?

comment:8 by Carl Eugen Hoyos, 11 years ago

dd is the recommended method but any other method that produces an output file that allows to reproduce the problem is also fine.

comment:11 by ob, 11 years ago

I guess the error you got before you edited your post was because the output directory didn't exist, which you apparently fixed. The new error does look like the last one I'm getting.

comment:12 by Carl Eugen Hoyos, 11 years ago

But your original report was about an assertion failure (which is an important crash), how can I reproduce it?

comment:13 by ob, 11 years ago

Yes, this bug drifted a little bit from the original report. I'll try to cut samples from the other VOB files to try and reproduce with concat and content I can upload. I'll update this when I'm done.

comment:14 by ob, 11 years ago

~/git/ffmpeg/ffmpeg -i new_bad.vob -map 0:1 -map 0:13 -codec copy -f segment output-%08d.nut seems to reproduce the problem consistently. It's crafted from the 298 first blocks of both VTS_01_0.VOB and VTS_01_1.VOB (each block being 2048 bytes). Hopefully this doesn't reproduce the problem for completely different reasons.
