Le duodi 2 messidor, an CCXVIII, Rolf Ernst a ?crit?: > Does anybody know how to set vorbis bitrate encoding options (lavcopts > acodec=vorbis:abitrate=xxx is ignored).

But you do not want to do that anyway: acodec=vorbis select the Vorbis encoder built into libavcodec, not the wrapper for Xiph's libvorbisenc. And this encoder is not good at all, it is only a proof of concept until someone undertakes to implement all necessary quality enhancements. In fact, there was recently two commits in ffmpeg: # ffmpeg: fail if user selected codec is experimental and # strict_std_compliance > experimental # Mark vorbis encoder as experimental. just to make sure people do not select this codec (and the AAC encoder, which is in the same situation) by mistake. You could try acodec=libvorbis; unfortunately, there are issues preventing its use in mencoder. As for myself, what I do is -ovc pcm -of rawvideo and pipe the result to vorbisenc.
