    Default FFmpeg's VP8 Decoder Blasts Google's Decoder

    Phoronix: FFmpeg's VP8 Decoder Blasts Google's Decoder

    It was just back in May that Google opened up the VP8 video format that they got their hands on through the acquisition of On2 and at the same time they created the WebM container format. VP8 has already received a lot of love by the open-source community -- both developers and end-users -- and support for it has already worked its way into FFmpeg, GStreamer, and other multimedia projects. Google released the libvpx library as their official VP8 decoder library, but now the FFmpeg developers have created their own decoder and it's shockingly faster than that of Google's own open-source library...

    I wonder what's the performance of libvpx compared to ffvpx on P4 32bit and simmilar machines (32bit, only one core (or HT) and high CPU clock (3GHz).

    I'm sure it'll do quite well even on a uniprocessor (or hyperthreading) P4 if the ffvp8 library is compiled with the right compiler flags.

    Yep, FFmpeg devs tend to make sure that things work well on all numbers of cores. so far as to say that any change for multi-core systems should not degrade single core performance. At least for h264, I would expect the same treatment for webM/vp8

    It is said to do 26fps with 1080p even on the Intel Atom which is excellent.

    I'd love to be able to watch quality 1080p content even on my aging Thinkpad T42

    Well did you see that the bitrate is only 4.5 mbit for those videos? Of course it is 1080p, but what matters is the bitrate. Well youtube will most likely not use much more, so it should be possible to decode it. But html5 still misses a good full screen playback.

    I'm sure that shortcoming will be fixed eventually once VP8 encoded video hits the mainstream

    remember that vp8 is not the ultimate ultra useless high bit rate ultimate killer video codec lol.

    vp8 is meant as a average joe nice youtube / or any other site with flash video replacement for html5. so 4 to 10 mbit is good enough.

    beside the bitrate of 40 is lol, even with my 32" 1080p tv is hard as hell to find any diff beetween 8 mbit or 100mbit except in some high speed scenes.

    ok for proffesionals o ppl with futuristic artifical uhd eyes 40mbits or more is neccesary but even these days BR is already an overkill like it is for the crappy eye average joe's

    I wouldn't say 1080p is overkill... you can still easily spot the massive single color squares on 1080p played at 1680*1050.

    I'm not videophile (I should be wearing classes).
