| Series | [v3,1/3] media: v4l2-ctrl: Add frame-specific min/max qp controls for hevc | expand |
Hi Dikshita, Just a few nitpicks, I'd have changed it myself, but since a new version is needed anyway you might as well change it for next time :-) On 18/11/2020 07:54, Dikshita Agarwal wrote: > - Adds min/max qp controls for B frame for h264. > - Adds min/max qp controls for I/P/B frames for hevc similar to h264. > - Update valid range of mim/max qp for hevc to accommodate 10 bit. double space after 'of'.
