Hello,
I simply try to encode a video to MPEG2 with below command:
ffmpeg -i ada-2016_06_06_15_45_39.ts -vcodec mpeg2video -minrate 1000k
-maxrate 1000k -vb 1000k -bufsize 1000k -acodec mp2 -ac 2 -ab 128k -f
mpets -muxrate 1250k -qmax 51 /tmp/out.ts
Qmax never goes over 31. I noticed I can not change qmin and qmax values
using -qmin & -qmax.
