XVideo may well use the GART to do image transfer if appropriate, but it will be doing one PC memory copy typically before X/Gart do their bit. > Do you know any example that works with by making yuv data available to > the gfx card? A deinterlacing app would probably benefit from using such > a transport. XVideo can supply YUV format data to the card, but it does go via the server at a small cost. I don't know if any of the DRI capable cards support YUV textures _______________________________________________ Video4linux-list mailing list [EMAIL PROTECTED] https://listman.redhat.com/mailman/listinfo/video4linux-list
