[FFmpeg-user] Converting 4:2:2 pro-res to 4:2:0 for AVC encoding

Hi all,
I have some mov files that contain 4K movies in 4:2:2 10-bit. I would like
to encode these to 10-bit 4:2:0 using x265. Since mov doesn't support
4:2:0, I am not able to convert these prior to encoding. The other option
is to convert to 4:2:0 and pipe to x265 binary using mpeg4yuv pipe, but
that would mean inter-process communication between ffmpeg and x265.

Is there any way that I can convert from yuv 4:2:2 10-bit to yuv 4:2:0
10-bit and pass to libx265 on the fly without going through inter-process

Any help would be greatly appreciated!
