Hi,
This series add a new intra-refresh period control for encoders. The
series is a continuation of [1]. Comments addressed:
* A typo in .rst (Hans)
* Clarified the relationship with CYCLIC_INTRA_REFRESH_MB (Hans)
Comments are welcome!
regards,
Stan

1) The same must be mentioned in the V4L2_CID_MPEG_VIDEO_CYCLIC_INTRA_REFRESH_MB
control documentation as well.
2) What does it mean: 'mutually exclusive'? Does that mean that a driver
implements only one or the other? If not, and both can be implemented, then
how does userspace know which control is applied?
Also, you mentioned that V4L2_CID_MPEG_VIDEO_CYCLIC_INTRA_REFRESH_MB is
enumerated in the venus driver, but doesn't do anything. Wouldn't it be
better to remove it?

Hans
