Thanks Carl, my use-case is to decode one stream as fast as possible, so I can't use the approach of running several single-threaded instances to speed up the process. > There is a x264 option that takes this into account iirc > but it may not suit your use case.) And I have to decode h264 videos from random sources, so I have no control of how the video being encoded. Can I say that, at the decoder side, there is nothing I can do to ensure all h264 videos from random sources can use the maximum CPU power to decode? > Intra-only streams allow to use much more CPU while decoding. Can you point out for me which tool can show if the h264 video is intra-only streams?
