[Openchrome-users] CN700 XvMC

[Trevor Kramer]

That's strange. I'm running the latest FC5 kernel  
(2.6.16-1.2133_FC5), the latest drm (which has the pci ids added) and  
openchrome drivers from cvs/svn and xine 1.1 and I just get a black  
screen with no errors. Here is the xine output.

video_out_xxmc: New format. Need to change XvMC Context.
width: 480 height: 288 mpeg: 1 acceleration: 7
video_out_xxmc: Surface type 0. Capabilities 0x       2 0x       4
video_out_xxmc:   Requests: 0x       1 0x       4
video_out_xxmc: Surface type 1. Capabilities 0x       1 0x       4
video_out_xxmc:   Requests: 0x       1 0x       4
video_out_xxmc: Creating new XvMC Context 842094169
video_out_xxmc: Using Backend subpictures.
video_out_xxmc: Using hardware decoding for this stream.

i get sound and osd even shows up in mythtv but the video is just a  
black box.
