Hi,
first of all: thanks for this great program! I just made a tiny donation, because you added some real cool features that made serviio the DLNA-client #1 for my Samsung C-Series TV! GREAT!!!!
One little noob question (i read some threads but could not get a clear answer): Does Serviio (/ffmpeg in use with serviio) benefit from hardware acceleration of HD-material?
I am asking this because a friend of mine has an ATI 4350 lying arround, which I could use for my DLNA-Server-PC.... If it makes sense.... The onboard graphics I am using at the moment is a GMA950.
Thanks in advance!
Stefan

nope grapphic card has no bearing on serviio's performance.

Thanks!
Just out of interest:
Are there any plans for the future regarding this topic?
Or is it impossible to get the stream back out of the graphics card after it has been processed?

It just sends the original or transcoded stream so the renderer needs the HW support. If it was on the Serviio side, you'd have to send a sequence of bitmaps over the network which is not doable (too high bitrate)

I see...
So it´s the turn of the ffmpeg people to implement CUDA/AVIVO support for transcoding....

NO hardware excelleration would have to be on the RENDERER not the server end

Well, it would also help during transcoding, if those guys implemented it. I think someone on this forum already mentioned it and there are some patches, but not all OSes

Yeah, I heard that TMPG-Express uses CUDA to accelerate transcoding in a very efficient way.
Anyway, Serviio+ffmpg is doing an excellent job and my multipurpose-24/7-pc (Mobile T5500 on desktop mainboard) is fast enough to deliver a nice output stream.
Best wishes,
Stefan
