Hello Kamil, Sorry for the delayed reply. I'm afraid this doesnt fix the whole issue. Still there is some problem with S_CTRL when used with custom controls. when my application call s_ctrl with V4L2_CID_MPEG_MFC51_VIDEO_DECODER_H264_DISPLAY_DELAY the call finally lands on V4L2_CID_MPEG_VIDEO_DECODER_MPEG4_DEBLOCK_FILTER in driver (The set value is also lost). I think this is because of corruption of the master or cluster in v4l2-ioctl.c/ctrl.c and pointing to the standard controls master. instead of the custom control master. Kindly, let me know your opinion or any clues on this.
