The kernel is 3.13-rc2, the mfc has been configured by dts, the dts is
attached below. I have placed s5p-mfc.fw in /lib/firmware/ .
I can use v4l2-ctl(from v4l2-utils) the encoder in the manufacturer
kernel, but I can't in here. What is the problem?
Thank you

Hi Randy,

We also experienced this issue. One of the changes in the v4l2 core
affected the MFC driver. A fix for MFC has been prepared by Marek
Szyprowski and should be sent out soon.

Also another tip - in 3.13 a check on bytesused and length fields
in planes array has been implemented. So make sure to set them
appropriately.

Best wishes,

Could you give me some example code of using samsung mfc v5 encode?
I only get some sample from samsung BSP's android-4.2.2, in
hardware/samsung_slsi/exynos4/multimedia/ , has
codecs/video/exynos4/mfc_v4l2/enc/src/SsbSipMfcEncAPI.c achived this?
Thanks

Thank you.
Well, mem2mem device seems hard to use for me, I never use streaming
before(I always use libv4l to do a read/write wrapper). I will some time
to make it work in my program :)
Thank you again for your help and work.
