Perhaps somebody can explain to me the meaning of mplex verbose, I have sometimes "freezes" on my dvd player (and I suspect too high bitrate) the mpeg2 reports no problem during muxing (with some muxers, dvd authoring softs, etc) but mplex says something like that: mplex -f 8 input.m2v ... -o output.mpg [...] Peak bit-rat: 11814400 This peak is > 10 080 000 kb/s (the maximum "size" of video for DVD) it's just a warning and not an error. I took a look the stream and my other tools/softs didn't detect an "overflow" (resulting stream seems to be ≤ 10 080 000). Somebody understand this warning? mplex is right or does it means anything else? (aka the result is compliant with dvd-specf or not?) ...rate control is always a problem (bigger in ffmpeg but present in mpeg2enc too) bye Hervé ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
