hi all, thanks for the replies. i compared the bit rates of 2 ogg files. one created by using ffmpeg (0k nominal, 41k avg), the other created by dumping a wav and converting to ogg using audacity (160k nominal,113k avg).
Is the quality (or lack of) extremely noticable? Ogg is variable rate, and by "VOB" i'm thinking "movie", where there may be a large variation of sound sources, compared to for example a music CD.
the lack of quality is extremely noticable. the VOB is indeed a video recording of a performance and i just wanted to get the sound. i can live with dumping wav and converting using audacity. its just too much pain.
Then again, it could be an ffmpeg problem. I don't have any ready vobs here to test. But I routinely dump audio from other sources (such as avi) and encode those with ffmpeg, but not to ogg, usually a52 because I do a fair amount of dvd encoding of avi movies.i have 0.cvs20070307-6 of ffmpeg and this seems to be the latest version. am i doing something wrong? or is there a better way of gettingThere's a later version 20071206 but it's in the debian-multimedia repository.
i will wait till it makes into unstable. its not a pressing issue. thanks for the suggestions.
