Yes, but in that case, zero division can't happen, because B == 0 is tested. For now, this is the line av_clip_uint8(B == 0 ? 255 : 255 * A / B)) I think something like this can be enough : B == 0 ? 255 : av_clip_uint8(255 * A / B)) Martin _______________________________________________ ffmpeg-devel mailing list [email protected] http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
