Hi, I am rewriting the DirectFB video render for GStreamer 0.9 and i have some questions on the latest DirectFB.
1) I m getting my video frames as IDirectFBSurface * , then i m blitting them or stretch blitting them to either the primary display layer's surface or an external surface the application provided me. Is it possible to blit surfaces that have different pixel formats ? 2) When stretch blitting is not accelerated, what is the best behaviour : a) tell the upstreams elements that we won't do scaling and let a videoscale element take care of that upstream ? b) try to lower the display layer configuration to something that's approaching the video geometry ? 3) I have seen on the drivers status web page that the Radeon driver supports Stretch Blit acceleration but it doesn't seem to be true, did i miss something ? 4) From the drivers page i can see that accelerations are supported only in some specific pixel formats. How does one grab from DirectFB the list of pixel formats that are hardware accelerated ? Thanks for your time and keep up the good work, Julien Moutte, _______________________________________________ directfb-dev mailing list [email protected] http://mail.directfb.org/cgi-bin/mailman/listinfo/directfb-dev
