It would then need a new "pixel format" for MPEG data. As for the buffer issue... Supposing that the buffer can't be mapped or if it's just impossible to present it as a surface buffer I suppose it could use a double buffered surface in system memory and feed the data to the hw on Flip(). -- Ville Syrj�l� [EMAIL PROTECTED] http://www.sci.fi/~syrjala/ -- Info: To unsubscribe send a mail to [EMAIL PROTECTED] with "unsubscribe directfb-dev" as subject.
