---------------------------------+---------------------------------------
 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
