Hi,
How is this going on, anything holding it back from getting merged ? I'm interested in adding/using P010, [1]
Thank you, Alex Gheorghe

Add P010 definition, semi-planar yuv format where each component is 16 bits 10 msb containing color value. First come Y plane [10:6] followed by 2x2 subsampled Cr:Cb plane [10:6:10:6]
Add P012 definition, semi-planar yuv format where each component is 16 bits 12 msb containing color value. First come Y plane [12:4] followed by 2x2 subsampled Cr:Cb plane [12:4:12:4]
Add P016 definition, semi-planar yuv format where each component is 16 bits. First come Y plane followed by 2x2 subsampled Cr:Cb plane [16:16]
