The correct way with FFmpeg is to use a perl script called dvd2concat along with FFmpeg to stitch the files together. If the vob files are split into segments, concat is probably the wrong method for joining them, but I can't find what the correct method might be, if ffmpeg has one. Anything non-sequential causes issues in FFmpeg's MPEG2 demuxer because it is unsupported, and if it's bad enough FFmpeg will lock up completely. MPEG2 files can have non-sequential timestamps throughout them. I'll try and address everything I can here. Wow, first off, thanks for the responses.

I am running Manjaro Linux, in case that matters.Ĭould you post exact errors that ffmpeg outputs? I tried AVIDemux, but if I recall correctly, it discarded the subpictures, so I can't use it. Is there some Linux, command-line based workaround that can fix the discontinuity before FFmpeg touches the files? Every single program seems to be moving toward using FFmpeg internally, so ultimately FFmpeg needs to be fixed, but I'm still curious. Is there some way to create non-copyrighted files worthy of a bug report to FFmpeg? (Or maybe someone here is an FFmpeg coder willing to take a look at what I have? I'd be happy to work 1-on-1 with someone!) Here's a video of what happens (1:15 onward): Since I am doing this with commercial DVDs, I cannot send a copy of the data to the FFmpeg team to create a bug report. Some discs have discontinuity in the VOB files, and apparently MPEG2 discontinuity is not supported by FFmpeg's demuxer, so when I try to run a concat: operation on the video files, FFmpeg gets stuck in an infinite loop. Everything works great, except for one major snag. I'm creating an automated system of Python scripts to rip DVDs, and using FFmpeg, reprocess them into a modern format (Including the original image-based subtitles & closed captions), and create a digital library, including all content from the discs.

Hi! I'm new around here, and I was hoping maybe someone might have some insight.
