Hi all, I'm having a problem with the color space trying to encode a raw video into mpeg4. The following command (full output at the end of this email): mencoder -vc rawbgr24flip input.avi -ovc lavc -lavcopts vcodec=mpeg4 -nosound -o output.avi prints: [swscaler @ 0335C550]using unscaled bgr24 -> yuv420p special converter and the colors in output.avi are not the same as the original, I suppose because the multiple conversions between color spaces. The following command: mplayer input.avi prints: [swscaler @ 0357C9F0]using unscaled bgr24 -> rgb32 special converter but: mplayer output.avi prints: [swscaler @ 00FFEDF4]using unscaled yuv420p -> rgb32 special converter So my question is if there is a command-line arg to force a bgr24 -> rgb32 special converter during the encoding process in order to avoid those unnecessary conversions. Any help appreciated.
