Exactly, I don't think you can reasonably expect a generic transcoder to be optimally performant in all cases. Every major change like this is a tradeoff and we have to pick those that are most broadly useful. A transcoding setup that encodes PCM and throws it away is not particularly useful, and the picture could change quite a lot once you add actual encoding. -- Anton Khirnov _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email ffmpeg-devel-request@ffmpeg.org with subject "unsubscribe".
