Hello
I have problems to generate AVC Intra files with full 10bit encoding.
It shrinks automatically to yuv422p: Incompatible pixel format
'yuv422p10le' for codec 'libx264', auto-selecting format 'yuv422p'
See complete command line here:
C:\Users\gersti>ffmpegnew -i I:\AVC-INTRA\00000_ffvhuff.avi -vcodec
libx264 -g 1 -pix_fmt yuv422p10le -vb 100M -x264opts avcintra-class=100
-x264opts colorprim=bt709 -x264opts transfer=bt709 -x264opts
colormatrix=bt709 -threads 8 -vf "setfield=1" I:\AVC-INTRA\00000_ffvhuff.mxf
