(Many, among them cabac vs cavlc, B-frames, bitrate and probably less obvious things. There is a x264 option that takes this into account iirc but it may not suit your use case.) > Is there a way to maximize CPU usage so that decoding can become faster? Intra-only streams allow to use much more CPU while decoding. Is your use-case to decode as many files as possible in a given time or to decode one file as fast as possible? If you have many files, -threads 1 is significantly more effective (up to the bandwidth of your hard disk).
