Description
I'm encoding WebM video using latest libvpx, and according to libvpxenc.c if I set AVCodecContext->bit_rate, rc_min_rate, rc_max_rate to the same value, I can generate a CBR video.
or I only set bit_rate, the vp8 encoder will try best to reach the desired bitrate.
These arguments work as described here https://ffmpeg.org/trac/ffmpeg/wiki/vpxEncodingGuide, but when I set them programmatically, it seems doesn't work
