Hello,
The patch fixes bug with CQ RC mode: max and average bitrate values were not
set to zero.
How to reproduce:
#CQ 30 file
ffmpeg \
-i big_buck_bunny_1080p_h264.mov -c:v h264_nvenc -preset medium \
-cq 30 -y output_cq30.mp4
#CQ 10 file
ffmpeg \
-i big_buck_bunny_1080p_h264.mov -c:v h264_nvenc -preset medium \
-cq 10 -y output_cq10.mp4
Before the patch, both output_cq30.mp4 and output_cq10.mp4 were of same size.
After the patch, output_cq10.mp4 file has higher quality and bigger size.

Looks generally ok, but I want to give it a few tests and haven't found
the time for that yet.
