Hi Mike,

Please test with enabled CMA(Device Drivers/Generic.../Contiguous Memory 
Allocator). I will test it further and update defconfig if necessary.

Please also apply latest published MFC patches(not yet in mainline), 
especially:
s5p-mfc: Fix second memory bank alignment
v4l/s5p-mfc: added support for end of stream handling in MFC encoder

Regards
Andrzej
