  • minimal cpu for hd

    Hi,

    I am wondering what is the minimal cpu to play 1080p movies.
    is E5200 enough or should I go for E7400 ?

    When you use vdpau with nvidia series 8 or 9 (best 512 mb vram) both cpus are fast enough.

      thanks, but at the begining, in case vdpau is not reliable or implemented I prefer know what I need to fallback.

        With a decent video card. Single core Atom. 1 ghz amd athalon, 1.8 ghz celeron. Anything really.

          is it hard to read the topic subject ?

            For software only and 1080p then you should use least a cpu with 3 ghz. But if you are lucky you can oc the cpu to that level...

              mirak63, just to be clear do you mean no GPU decode acceleration, or no GPU render acceleration (Xv, OpenGL) as well ?

              Your wording implies the second case, ie outputting to x11 or something, is that correct ?

                I don't see where my wording implies renderer acceleration

                However I still can tell you I can't play a 1080p video with a q9300 and opengl acceleration, while with xv it's ok. (but there is tearing)

                  Oh good, that's what I thought too

                  OpenGL will always have higher overhead than Xv for video playback; the GL output is just a useful short-term solution.

                  On the good news front, it looks like there is progress in standardizing sync-to-vblank in the framework; in this case in DRI2. Scroll down to "painflipping" :

                    NO but it's really hard to decode with a CPU. Which is why people generally don't do it.
