Processing recent cuts with ffmpeg

Post by berndb »

Currently, my cut TV-Recordings don't work well when processing them further with ffmpeg. The result has video and audio not in sync while the cut source file produced with smart cuttter plays fine in mplayer, xine & Co.
Is it worth to try to create sample and upload it? Would you need the source file (which means I try to make a small TV-recording where the error is reproduceable) or would you need a result made with smart cutter?

Here are an example of the messages ffmpeg shows when processing a file cut with smart cutter:

Re: Processing recent cuts with ffmpeg

Post by berndb »

Thanks for your reply and sorry for the late response.

Some further tries give me the impression that smart cutter suffers from corrupt input and is not the source of the error messages I reported. Processing another TV-record directly with ffmpeg gave me a lot of strange "PES packet size mismatch" errors. This and other things leads me to the conclusion that my current TV-Recording-Setting (vdr-1.7.38) is not working properly. I have to reinstall and check further.

Anyway, here is an example processed on an output of smart cutter. I use "--ss 00:36:00" to begin at one of the timestamps where the error occurs.
