Can you show us the output of the command... grep flags /proc/cpuinfo Then we can see what to add. If you are *NOT* taking advantage of the available extensions, you won't get the available oomph out of your cpu. It's not so much a matter of raw speed as ability to do complex calculations in the chipset microcode, rather than painfully emulating it in software. One of the features of Gentoo is customizing your build to get the most out of your cpu. Use it... within reason. mplayer also takes a few custom flags. In /etc/portage/package.use I have the entry media-video/mplayer custom-cflags i8x0 real 3dnowext mmxext With an Intel cpu, you obviously don't want 3dnowext, but there may be other stuff worth using.

[gentoo-user] Choppy video playback
Hi,
I'm having choppy video playback in mplayer, vlc and also in Firefox
on YouTube and the like. I notice a video freeze every 1-2 seconds or
so, then the video snaps back to where it should be. The audio sounds
fine. Mplayer often spits out a warning message[1].
I also noticed that typing into forms (like an email in Gmail) in
Firefox, after Firefox has been running a few hours also suffers from
this freeze every 1-2 seconds.
A typical workload is Gnome, Firefox, Claws-Mail, Pidgin, Tomboy,
xmms2 and a bunch of terminals with SSH sessions and irssi.
I have an Intel Core 2 Duo 2GHz with 2 GB of RAM, so this shouldn't be
happening. I'm running kernel 2.6.23-gentoo-r3. I don't remember when
exactly this started, I don't really watch video too often.
Could it be the scheduler with which my kernel is compiled? Currently
it's set to Preemptible Kernel (Low-Latency Desktop).
Any ideas? What to start tweaking with?
Thanks for any help,
Mike
[1] Mplayer warning message:
Your system is too SLOW to play this!
Possible reasons, problems, workarounds:
- Most common: broken/buggy _audio_ driver
- Try -ao sdl or use the OSS emulation of ALSA.
- Experiment with different values for -autosync, 30 is a good start.
- Slow video output
- Try a different -vo driver (-vo help for a list) or try -framedrop!
- Slow CPU
- Don't try to play a big DVD/DivX on a slow CPU! Try some of the lavdopts,
e.g. -vfm ffmpeg -lavdopts lowres=1:fast:skiploopfilter=all.
- Broken file
- Try various combinations of -nobps -ni -forceidx -mc 0.
- Slow media (NFS/SMB mounts, DVD, VCD etc)
- Try -cache 8192.
- Are you using -cache to play a non-interleaved AVI file?
- Try -nocache.
