[PATCH 0/2] add MBR type rate control for encoder

Posted by Sachin Kumar Garg 1 month, 2 weeks ago

This series adds the support for MBR rate control type in the
Iris driver.
The changes include:
- Add MBR Rate Control definition in the v4l2-ctrl.
- Add MBR Documentation in the v4l2-ctrl.
- Add MBR RC handling in the Iris driver for sc7280.

I have validated this series on sc7280 using the below test application
by setting the BitRateMode control to V4L2_MPEG_VIDEO_BITRATE_MODE_MBR:
