************************************************
**** 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.

在fedora 8下安装mplayer：过程如下

首先当然是要下载安装包。

主文件 http://www1.mplayerhq.hu/MPlayer/releases/MPlayer-1.0rc2.tar.bz2

编码包 http://www1.mplayerhq.hu/MPlayer ... ll-20071007.tar.bz2

win32 编码包http://www1.mplayerhq.hu/MPlayer ... ws-all-20071007.zip

皮肤 http://www1.mplayerhq.hu/MPlayer/skins/Abyss-1.6.tar.bz2

字体http://www1.mplayerhq.hu/MPlayer ... gb2312-ming.tar.bz2

当然可以到这儿了解最新的信息和自己想要的东西 http://www1.mplayerhq.hu/

下载完后解压解码器包放到/home/eplinux/download下,这个路径随个人爱好，想放到那就那。然后解压。在解压之前应该建好存放编码器的目录 sudo mkdir /usr/lib/win32

一般情况下／usr／lib／codecs在安装时就默认建立了，如果不放心可以查看ls －l ／usr／lib／没有创建就ok。

cd ／usr／eplinux／download

进行解压：
tar jvxf all-20071007.tar.bz2

unzip windows-all-20071007.zip

ar jvxf MPlayer-1.0rc2.tar.bz2

tar jvxf Abyss-1.6.tar.bz2

tar jvxf gb2312-ming.tar.bz2

解压完成。

mv windows-all-20071007 /usr/lib/win32

mv all-20071007 /usr/lib/codecs

cd MPlayer-1.0rc2

./configure --prefix=/usr/local/mplayer --enable-gui --codecsdir=/usr/lib/codecs --win32codecsdir=/usr/lib/win32 --language=zh_CN

开始编译安装：
make

make install

这儿得一小段时间，大家可以干下别的，喝杯coffee。

主程序到此完成，下面安装皮肤和字体
cd ..
mkdir /usr/local/mplayer/share/mplayer/skins/default
mkdir /usr/local/mplayer/share/mplayer/font/
mv Abyss /usr/local/mplayer/share/mplayer/skins/default

cd gb2312-ming/gbsn00lp16/

sudo cp * /usr/local/mplayer/share/mplayer/font/

呵呵，就这么简单。ok！

/usr/local/mplayer/bin/gmplayer 一切原来这么美好哦，我的最爱，你也能播放了。

貌似没有安装编解码库导致的...

如果要在Fedora 8下安装mplayer播放器,那么首先肯定要在mplayer网站上下载以下文件

http://www1.mplayerhq.hu/MPlayer/releases/MPlayer-1.0rc2.tar.bz2

http://www1.mplayerhq.hu/MPlayer/releases/codecs/all-20071007.tar.bz2


http://www1.mplayerhq.hu/MPlayer/releases/codecs/windows-all-20071007.zip

skin http://www1.mplayerhq.hu/MPlayer/skins/Abyss-1.6.tar.bz2

font http://www1.mplayerhq.hu/MPlayer/contrib/fonts/chinesefonts/gb2312-ming.tar.bz2

下载完后 解压解码器包放到/usr/lib/下

tar jvxf all-20071007.tar.bz2

sudo mv all-20071007 /usr/lib/codecs

unzip windows-all-20071007.zip

sudo mv windows-all-20071007 /usr/lib/win32

现在解压MPlayer-1.0rc2.tar.bz2

tar jvxf MPlayer-1.0rc2.tar.bz2

cd MPlayer-1.0rc2

sudo ./configure --prefix=/usr/local/mplayer --enabel-gui --codecsdir=/usr/lib/codecs --win32codecsdir=/usr/lib/win32 --language=zh_CN


编译安装make

make install

安装完后解压skin和font

tar jvxf Abyss-1.6.tar.bz2

sudo mv Abyss-1.6 /usr/local/mplayer/share/mplayer/skin/default

tar jvxf gb2312-ming.tar.bz2

cd gb2312-ming/gbsn00lp16/

sudo cp * /usr/local/mplayer/share/mplayer/font/

好了,一切成功！
