I haven't tried it myself, but actually logarithmic should be stored in FFV1 as-is. The context how to interpret the color information is currently not automatically stored, and would therefore have to be provided manually when re-transcoding, or when playing back. Has anyone tested this yet? Kind regards, Pb _______________________________________________ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-user
