我的电脑的配置:
CPU: P4 1.8G
video card: nVidia Corporation NV17 [GeForce4 MX 440] 64MB
memory:512MB
os: debian unstable
mplayer version: 1.0rc (从源代码编译的)
当其他后台程序占用CPU大约40%时并且内存还剩300MB,用mplayer播放任何视频都会报"Your system is too SLOW to play this!",然后视频输出就会比音频慢一些，导致视频和音频不同步;
mplayer有什么优化可以解决这个问题阿？现在在Linux上看视频好不爽~~~

- ************************************************
- **** 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.
- Read DOCS/HTML/en/video.html for tuning/speedup tips.
- If none of this helps you, read DOCS/HTML/en/bugreports.html.
