1) pixfmt.h applies to AVFrame not AVPacket really, it can be a bit confusing for raw formats that way though 2) this part just says that RGB32 is short for "bigendian ? ARGB : BRGA", it is not really its own format, so I miss a bit of context why it is relevant for palette. _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
