    I have a few avi files which are encoded in vp7 codec. I'm not able to play them on vlc or mplayer.
    From where can I get this codec for linux?:confused:

    AFAIK exist no vp7 codec so far for linux...some license issue or dont know for some reason vlc ignore to include support for vp7 in its player...
    linux=no vp7

    @bharat..where do you get vp7 coded files?

    then has someone tried it with wine ?

    VP7 betters H.264, but due to the existance of x264, an encoder thats cross platform and developed by the VideoLAN team, VP7 decoding doesn't get a high enough priority from them.

    But a decoder is underway in FFMPEG(and concequently VLC) and will be released as soon as possible. But an encoder is a long way off.

    PS: a non native Win32 dll which can be loaded to MPlayer and Xine is available, but its not fast.

    all win32 dll files that mplayer and xine use have this performance drop due to the fact that the dll is made for an entirely different platform.

    the dll is located in the mplayer win32 dll package. you must be knowing where it is.

    ^Coz , its a non native os file being used.
    Mplayer has to use it via a wrapper of sorts to decode the video.
    Although , i personally havent seen any performance drop decoding quicktime videos in mplayer.
    AFAIK, it uses win32codecs to decode them.

    ^Mplayer doesnt just use windows codecs for all the videos.
    It does use native codecs for supported formats.
    IMO its the best video player around.

    Offtopic:VLC also has a mozilla plugin like mplayer,
    I've only used mplayer's one, can someone tell me how the VLC one fares?

    Its quite feature rich and excellent. Waaaaay better than MPlayer plugin IMO. But MPlayer plugin is prefered as VLC lacks Win32 DLL Loading Capability. There was a test page on VLC website which had a text box and the plugin window below, and you could paste any video URL in the text box and it could be played on the plugin window. It was an awssome demo. But I forgot the link to that page, which was kindly pointed out to me by a VideoLAN developer when I said there is no VLC plugin based page online so that I may test that plugin.

    jab convert kar saktha hai, play kyon nahi kar saktha ?
    VP7 is just too good to be converted to another format. h.264 included.

    So there is no way I can view those files I guess.

    I download some episodes of a TV show which comes on Star Vijay. Those were in vp7.

    didn't you read each link posted ?
    go to the following link, and in Firefox, do a ctrl+F to bring page search and type VP7.
    http://www.mplayerhq.hu/DOCS/codecs-status.html

    then you will gain something good.;)

    not my forum..but admin cum everything over there..
    initially I started encoding with realmedia..then wmv..now vp7.
    have tried both x.264 & ogg theora..not satisfied with the end results...
    vp7 is the best for low bitrate video encoding.

    The problem with VP7 & Mplayer was ,when I drag & drop the video into the player,it doesn't play & gives the following error:

    [​IMG]

    But when I open the video from the player,it plays.
