Jonathan Michaels: |> Hermes or SDL might be good libraries to use under-the-hood to do the |> the pixel format conversion (Hermes already has MMX support; been testing |> it recently with bktr TV and it looks promising). | |here goes, what if your cpu dosnt have teh mmx extensions ? |will this mean that the software, won't run, or run so pooryly |that you will have to get a cpu that does do mmx or not bother |witht he software package. Very good question. No, definitely not. If MMX isn't supported by the CPU it wouldn't be used. Slower non-MMX code would kick in. Also, different from Fxtv today, this daemon would pace itself so it wouldn't bring your machine "to its knees" when it needs to revert to CPU-intensive conversion methods. This pacing ideally would be configurable based on a target CPU load or target frame rate. |reason i ask is that me (and a group of fellow freebsd users) |have old hardware, that is intel processors circa pentium pro |and the plain pentiums (the ones that didn't do mmx). i'm |looking at getting a g400 with video and possibly tv latter |this year. I think it's very important to support all our existing hardware! (Heck, all my video/multimedia cards are still hanging off a 33MHz PCI bus with a Socket 7 MB and 66MHz memory bus; until recently running a P-233MMX too. Hey, with my recent K6-III 400 upgrade, my trusty old Socket 7 can do full-speed DVD decode in software and full-screen video/audio playback with no dropped frames! Best CPU I ever bought. 3 Cheers for Old Hardware!). |i may be a bit premature with my question .. sorry, if i am. Not at all. Good questions!
