I'm interested in enabling cyclic intra refresh and fixed size slices. I've set the controls V4L2_CID_MPEG_VIDEO_CYCLIC_INTRA_REFRESH_MB to 1 V4L2_CID_MPEG_VIDEO_MULTI_SLICE_MODE to V4L2_MPEG_VIDEO_MULTI_SICE_MODE_MAX_BYTES V4L2_CID_MPEG_VIDEO_MULTI_SLICE_MAX_BYTES to 20 * 1024 I've checked that these are making it to the driver, but they seem to have no effect on the encode. Are there any limitations, or other controls that need to be set to enable these? Cheers, Mike
