Misdetecting FPS (16.7/20fps) when powernow is activated
#1
Hi,

I'm running trunk (R16479) on Ubuntu 8.10 on a GeForce 8200 board with an Athlon X2 6000+ CPU.

When powernowd is activated, XBMC tends to misdetect the FPS of video streams at ~16.7fps or 20fps (depending on the actual stream fps), and playback is subsequently very jerky.

Deactivating powernowd fixes the issues, no fps misdetection occurs.

Best Regards,
Olli

my best guess is that powernowd is messing with the computers clock. hardly much we can do about that.
Always read the XBMC online-manual, FAQ and search the forum before posting.
Do not e-mail XBMC-Team members directly asking for support. Read/follow the forum rules.
For troubleshooting and bug reporting please make sure you read this first.

Hm. clock_gettime() really shouldn't be influenced by the CPU frequency changes. I've been looking through the source, but so far haven't found anything where XBMC would rely on something CPU-speedish...

I'd very much liked to get cpu frequency scaling to work in conjunction with XBMC, since it's important to building a low-noise HTPC.

Best Regards,
Olli
