[theora-dev] Theora support in ffdshow a ffvfw

[Dan Miller]

hi --
 
this is great but please keep in mind Theora is Alpha release only!  Note there is a working VFW codec in theora cvs that is fully optimized; the theora package that builds command line tools is development-stage code, and is not optimized at all for fast playback.  Furthermore, the bitstream is not guaranteed to stay stable.
 
Please make sure to update your product as we move towards an officially maintainable release.

        Hi,
        
        I'm developing ffdshow and ffvfw codecs for Windows. You can read more
        about them at http://cutka.szm.sk and http://sourceforge.net/projects/ffdshow.
        Stéphane Bérubé asked me recently if I could implement Theora support. I knew
        about first Theora release, downloaded its sources and tested it. I liked
        the results add decided to support it.
        I implemented encoding functionality into ffvfw, which is Video for
        Windows codec. Frames aren't stored in Ogg stream, but in AVI.
        Decoding is done by ffdshow, which is DirectShow filter and almost
        every media player for Windows can use it.
        If you are interested in them, I will post links for downloading
        and short instructions how to use them.
        For now I would like to ask you for more info about theora_info struct
        fields, especially about those 'encoding only' parameters. Also I
        would like to know if there is possibility to set quality separately
        for each frame during encoding: if yes, two pass encoding should be
        easily possible.
        
        Thank you
        
           Milan
