[FFmpeg-user] AVCHD from a Canon HF G10: 'non monotonically increasing dts' + dts mess

[Damian Stewart]

I've discovered that ffmbc http://code.google.com/p/ffmbc/ can do this out of the box:

ffmbc -i 00167.MTS -vcodec copy -acodec aac -ab 256k 00167.mp4 

produces an .mp4 that Quicktime is perfectly happy to play. I wonder how easy/difficult it would be to backport ffmbc patches to ffmpeg?

I managed to get this working in my case with a hack in the code by replacing a ">"-Check with ">=" where the error occurred but it might be something else in your case and of course that was not a proper fix but if you want to get your material transcoded, you probably don't really care about that (I didn't). In any case, having this in the bug tracker with a small sample increases chances that someone can/will fix it. Please provide the camera model and recording mode in your bug report so others find this when they run into the same problem.
