Hello,
my country now as an HD channel : HD suisse;SRG SSR idee suisse:12399:hC34:S13.0E:27500:10180+180:0;131=deu,132=fra,133=ita,134=eng:0:0:990:318:8500:0
It's 720p with AC3 for the four audio. I have a quiete strong CPU but it's barely enough to decode this as vdr/xine seems to only take one core of it, even if I have set 2/4 for the processing.ffmpeg thread count.
(By the way, should I better set it to 2 as I have only two cores or to ??? )
Anyone know how to use both cores for this channel (like it's done for BBC HD;BSkyB:10847:vC56:S28.2E:22000:12318+2318:2320=NAR;2319=eng:2321:0:6940:0:0:0 ?
Thank you very much,

Don't think that there will be much gain by setting it any higher than 2.

The problem is that HD suisse codes each frame with only a single slice but FFmpegs multithreaded decoding needs multiple slices per picture.
There are thoughts to add picture based multithreading in addition to the currently existing slice based multithreading.
Bye.

Oh I see, I would really like this :-)
I'll happily test any patch...
Thank you very much,

Hi, I am wondering which hardware is good enough for HD suisse. What hardware are you using (cpu, gfx card) and how high is your cpu load? Jörg

Hello,
I got a Core 2 Duo at 2.4 GHz with Nvidia Geforce 7600 GS which isn't enough to decode HD suisse right now because as wrote Reinhard Nissl :

I don't know if those thoughts are for a near future or not...
For some time, my CPU is enough, but only a few seconds, then I loose sound because the CPU isn't enough.
