I tried it just now, and both player_example_theora and mplayer play the 444-file the same way, that is showing correct Y component but wrong colors. So I'll conclude that mplayer works and there is something wrong in my program :) > FFmpeg's theora decoder can't decode that, so if you end up using that it can't. > It should be able to if you compile it against libtheora and make it use it > (not sure if just -vc theora works). Yes, sorry, I forgot to mention that I'm compiling it against libtheora 1.1 and theora codec get chosen: ========================================================================== Opening video decoder: [ffmpeg] FFmpeg's libavcodec codec family [theora @ 0xcf52e0]Missing extradata! Could not open codec. VDecoder init failed :( Opening video decoder: [theora] Theora/VP3 Movie-Aspect is 2.35:1 - prescaling to correct movie aspect. VO: [gl] 1280x544 => 1280x544 Planar YV12 Selected video codec: [theora] vfm: theora (Theora (free, reworked VP3)) ========================================================================== Thank you both for your help.
