Re: [PATCH 3/6] [media] s5p-mfc: add support for VIDIOC_{G,S}_CROP to encoder

Hi John, Thanks for the patches! It's nice to see fixes/improvements like this being upstreamed. Unfortunately I have to NACK this patch, but fortunately it is not difficult to fix. The main problem is that you use the wrong API: you need to use G/S_SELECTION instead of G/S_CROP. S_CROP on an

[PATCH 1/6] [media] s5p-mfc: fix DISPLAY_DELAY

V4L2_CID_MPEG_MFC51_VIDEO_DECODER_H264_DISPLAY_DELAY_ENABLE is being ignored, and the display delay is always being applied. Fix this. Signed-off-by: John Sheu --- drivers/media/platform/s5p-mfc/s5p_mfc_opr_v6.c | 7 ++- 1 file changed, 2 insertions(+), 5 deletions(-) diff --git a/drivers/

[PATCH 4/6] [media] s5p-mfc: support dynamic encoding parameter changes

Add support for dynamic encoding parameter changes in MFCv6. Parameters set are applied with the next OUTPUT buffer queued to the device with VIDIOC_QBUF. Supported parameters are: * GOP size (V4L2_CID_MPEG_VIDEO_GOP_SIZE) * framerate (from VIDIOC_S_PARM) * VBR target bitrate (V4L2_CID_MPEG_VIDE

[PATCH 6/6] [media] v4l2-mem2mem: allow reqbufs(0) with "in use" MMAP buffers

v4l2-mem2mem presently does not allow VIDIOC_REQBUFS to destroy outstanding buffers if the queue is of type V4L2_MEMORY_MMAP, and if the buffers are considered "in use". This is different behavior than for other memory types, and prevents us for deallocating buffers in a few cases: * In the case

dvb-apps/util/scan: zap compatible with w_scan (option)

Hi. The feature is useful if you have file generated by "w_scan -X" and your card is just tuned and works. I could use "scan -c -o zap -a 0" to update the file but it wan't full compatible with w_scan. Now it can be with "-p" option like for VDR output format, ie. "scan -c -o zap -a 0 -p". I
