I found the origin of this color system. It was originally used with the first gba video paks (which used a way different codec). It is being described in this patent by Majesco (the 7th image, FIG. 4A and FIG. 4B): https://patents.google.com/patent/US7253819B1/en Later gba video paks seem to use the actimage vx format, so I guess there must have been a collaboration of some sort there. _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-devel
