Hi, sorry for intruding on the mailing list, but this is a topic on which I worked recently. First question is: I implemented yuv to rgb conversion using GLSL shaders (only for yuv420p, but this could be easily implemented for other pixel formats), and the code is relatively simple: https://git.click-hack.org/vplayer.git/tree/lib/yuv420p_frag.glsl What is the gain of using libva instead? Second thing is that I write some piece of code to compute the values of the matrix for several color spaces (using the ffmpeg enum). Code may be found here: https://git.click-hack.org/vplayer.git/tree/lib/csc.c Maybe this could be of interest.
