I just share something I read on the XBMC [1] Web site. The Broadcom Crystal HD Hardware Decoder (BCM970012) seems to be an alternative for HD playback with free drivers [2]. You can get it at as an mini-PCIE card at eBay for 22 $ [3].
I'd recommend the BCM70015, which is the better part.
where is it possible to buy it ?
It works as a decoder only, making YUV 4:2:2 frames available, which must then be blitted to whatever output framebuffer setup you have, over the pci express bus. The API seems very straightforward, much simpler that VDPAU, thus one could get a HW accelerated H.264 setup without X11.
what about of corrected interlace output ? Most of them videocards can't do it correctly....
