Encoding H264 422 in MXF

[in...@opsomai.com]

I am trying to generate a MXF file with H264 422 video (high422 profile) from a DNxHD185x source and I am facing 2 problems:

- high422 profile seems to be not supported

>ffmbc -i IN.mov -f mov -vcodec libx264  -pix_fmt yuv422p -profile high422 -g 1 -b 100000k -s 1920x1080 -acodec copy

-> Incompatible pixel format 'yuv422p' for codec 'libx264', auto-selecting format 'yuv420p'

I tried every 422 pixel formats and I got the same result. The generated MOV file is correct, but in 420 pixel format.

- MXF / H264 seems to be not supported

>ffmbc -i IN.mov -f mxf -vcodec libx264  -pix_fmt yuv422p -profile high422 -g 1 -b 100000k -s 1920x1080 -acodec copy

-> [mxf @ 0x26a7e80] track 0: could not find essence container ul, codec not currently supported in container

Did anyone face these problems before or are these formats not supported yet by ffmbc?

H.264 in MXF is not currently supported.
