Hi!
I am interested in your experiences with xineliboutput-plugin and vdr-sxfe for HDTV and not using VDPAU but using the plain CPU-power.
The plan would be to build a simple system without any special graphics-card and no special X11-configuration or driver, perhaps some cheap system like the one descibed in http://ct.de/-1375124 (German). (Celeron G1820, small case, low power consumption, about 180 EUR without disks.)
I know from my own VDR-systems, that a Intel Core2 Duo @ 1.86GHz or a Core i3 540 @ 3.07GHz has far enough power to run VDR and vdr-sxfe for displaying HDTV.
But I think even slower and thus cheaper CPUs could do the HDTV-decoding, too.
What is you experience? Would it be possible to use these new Haswell-Celerons?
TIA and best regards, Stephan.
It might be even cheaper to get a cheap Nvidia card along with s power saving CPU. My player is an ION board with an Atom 230...

My personal experience is that i5-2500K 3.30GHz plays HDTV well, but playback on E6500 2.93GHz is jerky.

I'm using an Intel Atom 330@1.60Ghz with nVIDIA MCP7A-ION chipset using a VDPAU installation (yaVDR).

That's similar to my experience. I have a 3.1GHz i5-2400k and that can playback HD smoothly, but my 3.2GHz Phenom couldn't. That might have been my fault for not discovering the thread count option before using the i5 though :-). The deinterlacing method makes a big difference too, but xineliboutput makes that difficult to configure sensibly when you have a mixture of clients with and without VDPAU.
Using VDPAU drops the cpu requires to practically nothing. For example, my weakest VDR box is running on an Intel Atom 230 1.6ghz with ION gpu (1st gen). Watching 1080i with temporal-spatial deinterlace, the cpu hovers around 12%. Even when using software deinterlacing, it doesn't take a lot of cpu horsepower until you want to use advanced/high quality deinterlacers.
That being said, it's hard to beat VDPAU. For the cost of about a $30 video card, you can turn an old piece of crap pc collecting dust in your closet, into a full-blown htpc.
