Hi, I'm using v4l2 with bttv, and would like to capture YUV with highest possible chroma resolution. However, the best supported capture formats as reported by the driver do 4:2:2 subsampling (of course, that's how it usually is). Would it be difficult to implement a 4:4:4 YUV (planar) format in the driver? Such a format would probably be quite useful for (color) machine vision applications in general... BTW, it's easy enough to do RGB->YUV in software, and it would get me full chroma res, but the app is rather starved for cycles (typical for machine vision;). See ya, - Reinoud
