Centos yum安装的Mplayer播放AVI时杂音非常大，别的格式则没问题

quifei

rpmforge源yum安装的mplayer，播放AVI文件时杂音非常大，基本上听不清，播放其他格式的都没问题，解码器是essencial amd64 和wingdows all，怎么解决？

另外一个问题是播放“北京欢迎你_WMV_清晰完整版_.wmv”时没有声音，提示error: cannot find codec for audio format 0x162，只发现只有播放这个文件才这样，其他wmv的文件没有问题。

终端运行提示为：

好像都还是解码器的问题，那  0x162 是 M$ MP  9.0/10.0 的格式。你装的解码器是什么？用 w32codec 试下？

quifei

解码器是essencial amd64 20071007和windows all20071007或windows essencial 20071007(两个都试过），因为系统是64位的，只能用essencial amd64 20071007

另外我在root用户里试了一下，播放AVI文件时没杂音，个人用户里播放有问题，
第二个问题“0x162”： root和个人用户都有，

    偶然发现两个用户的Mplayer的preference中的audio codecs 有点不同，root用户的是none，个人用户的是FFmpeg/libavcodec audio decoders（参见图），而且我想把个人用户的改成none却改不了，改成none后重新启动mplayer又变成FFmpeg/libavcodec audio decoders，不知道是不是这个音频解码器设置引起的？怎么样才可以改？

下面是root和个人用户下终端播放两个文件的信息：一个文件是a.avi 另一个是《007大战猪肉王子》国语DVD(胡戈2008贺岁片).avi.

root用户播放a.avi

自己给自己顶一下

pingz

不明白，你 ~/.mplayer/config 中的设置不起作用吗？建议尝试一下 smplayer 或是其它前端。

hades

我用CENTOS 5.2,自己编译的MPLAYER，什么格式的都能播放，没任何杂音。
PS：可能是你的声卡驱动或是artsd的问题。

quifei

我把~/.mplayer整个目录删掉就可以了，没有杂音，奇怪，原来的config只是设了monitoraspect=1440*900 和ontop=yes，其他的什么也没有
但是0＊162的问题依然存在

那个 0x162 是应该解码器的问题，我是 32 位机器，放了几个都没问题，你再找找看有没有别的解码器吧。
