MFC decode failed in S5PV210 in kernel 3.8

Hi,
I tested the MFC decode example v4l2_decode from
http://git.infradead.org/users/kmpark/public-apps and meet some problems as following:

# ./v4l2_decode -f /dev/video5 -m /dev/video9 -d /dev/fb0 -c mpeg4 -i
shrek.m4v

Error (mfc.c:mfc_dec_setup_capture:283): Failed to get crop information

And kernel print:
s5p_mfc_handle_error:420: Interrupt Error: 00000035
vidioc_g_crop:782: Cannont set crop

It seems MFC buffer parameters error first.
The shrek.m4v comes from http://www.uky.edu/~drlane/com351/shrek.m4v and is H264 format. But if I use -c h264, then v4l2_decode will print:
Error (parser.c:parse_h264_stream:337): Output buffer too small for current frame
Error (main.c:extract_and_process_header:71): Failed to extract header from stream

Any suggestions?

Thanks.

Thanks.

Maybe the up issue due to the input file format. Now I use a H264 ES file as input, failed with different output.

Which firmware should be used for S5PV210 for kernel 3.8? Here:
https://git.kernel.org/cgit/linux/kernel/git/firmware/linux-
firmware.git/commit/?id=fb5cda9c70277f633ca0c1e81b6fa7b13007bbf6 It only says for Exynos4 series :
for s5p-mfc.fw - For v5 firmware used in Exynos4 series
Does the firmware have any relation with compiler armhf or armef?

Thanks.

Hi,
I tested the MFC decode example v4l2_decode from
http://git.infradead.org/users/kmpark/public-apps and meet some problems as following:

# ./v4l2_decode -f /dev/video5 -m /dev/video9 -d /dev/fb0 -c mpeg4 -i

And kernel print:

It seems MFC buffer parameters error first.
The shrek.m4v comes from http://www.uky.edu/~drlane/com351/shrek.m4v
and is H264 format. But if I use -c h264, then v4l2_decode will print:
Error (parser.c:parse_h264_stream:337): Output buffer too small for current frame Error (main.c:extract_and_process_header:71): Failed to extract header from stream

Any suggestions?

Thanks.

Maybe the up issue due to the input file format. Now I use a H264 ES file as input, failed with different output. #./v4l2_decode -f /dev/video5 -m /dev/video9 -d /dev/fb0 -c h264 -i c.h264
