10 bit 4:2:2 UYVY (v210) into x264

[Asmodian]

I have some raw 10 bit UYVY (v210) captures and I have been unable to feed them into x264 keeping 10 bit and 4:2:2, x264 reports it converts to 4:2:0 then back to 4:2:2 internally.

I don't need to do anything to them, just encode the raw interlaced video.

Of course I do not NEED to do this, casually viewing the video I do not notice if I convert to 8-bit or 4:2:0 but it seems like it should be possible and I am encoding using 10 bit x264 anyway.

Does anyone have any ideas?

If this cannot be done at the moment would keeping 10 bit or 4:2:2 sampling be more useful, assuming interlaced video?

This sounds like a bug. kemuri9 might be able to look into it.

Thanks! Here is some more information if it will help.

This gives a normal looking test.mkv:

This gives a messed up video:
H:\>x264_x86_10bit.exe --preset slow --crf 17.0 --tff --output-csp i422 --output H:\test.mkv test.avi

Yes, this is a known bug, I finally have some time to try and resolve this.

The decoding part should be a separate issue though...
Asmodian, what are you using to decode the generated video?

I was using LAV 0.40 to get that picture. Testing with CoreAVC 3.0.1 and ffdshow tryouts rev3984 give a black screen.
