[FFmpeg-user] MPEG-TS CBR?

[Anjo Krank]

So I got some more info on the rejected CBR TS. Checking the generated streams with "crosscheck" yields a long list of errors:

The problem seems to the in fact the muxer, as de- and remuxing with a different muxer yielded no more errors.

How "usable" or "broadcast-ready" is the muxing in ffmpeg? Searching the web and other comments seemed to say that there is no actually working open-source muxer out there… at least in the sense that it could create broadcast-ready files. Is that true?

I also found a discussion about some patches that were written in the Google SOC 2009 which seemed to end in abandonment. Was that stuff actually working or better than the current implementation? Would it be worth the bother to clean it up and try to commit it?

From mucho googling I had the impression that it could maybe be a wrong setting for the  -bufsize 1000k. Is this on any way calculable or are they simply a bunch of legal settings?
