The twoloop coder (not the default) does CBR. The fast coder for now tries to approximate it. So the documentation is correct. If you do need more accurate CBR just use the twoloop coder for now. I'm working on the encoder now and that should improve its CBR constraints with the fast coder. _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email ffmpeg-devel-requ...@ffmpeg.org with subject "unsubscribe".
