As far as my very limited knowledge goes the Theora video format is less complex than H.264 (High Profile for example). Please correct me if I am wrong. Does this also mean that I can expect that decoding a Theora stream is easier/faster to decode than a H.264 stream with comparable quality / or comparable bitrate? My (very practical) tests do show that it's easier for my computer to decode the same video as Theora than H.264 which stutters more easily. It would make sense that decoding something less complex is faster than something more complex. At least as long as no hardware video acceleration comes into play. Can someone confirm this or has someone perhaps verified this in the past? Regards, Franz

In pure software decode, decoding Theora will generally be faster than decoding H.264 (especially High Profile), all else being equal. -------------- next part -------------- A non-text attachment was scrubbed...
