Hi,
This series add a new intra-refresh type control for encoders.
this can be used to specify which intra refresh to be enabled,
random, cyclic or none.
Thanks,
Dikshita

Slight annoyance, we now have two mechanism to disable intra refresh. Disabling
intra-refresh was previously documented as "Note that this control will not take
effect when V4L2_CID_MPEG_VIDEO_INTRA_REFRESH_PERIOD control is set to non zero
value."
Perhaps we should drop this and add a similar line in this control documentation
?
