Encode a 10bit raw video file I have a raw file that's in gray10le format. Each gray value is 2 bytes but only the first 10 bits are used. I can't seem to get x264-10b to accept it as an input.

x264-10b.exe --profile high10 --input-csp gray10le --input-depth 16 --fps 30 -o out.264 0_400x400_gray10le.yuv
raw [error]: unsupported colorspace `gray10le'
x264 [error]: could not open input file `0_400x400_gray10le.yuv'


I'm using the latest 10bit build at http://download.videolan.org/pub/videolan/x264/binaries/win64/
AFAICT, it should be --input-csp i400 --input-depth 10
