mplayer 每播放（很流畅）一段时间后，就会顿一下，顿的时间大概0.5秒钟。如何解决？
经常这样顿很不舒服啊。

开了本地缓存？

franklin2k · **发表于 :** 2012-05-21 15:22

本地文件缓存为0

mjp123 · **发表于 :** 2012-05-21 17:00

mplayer -cache 8912 XX
试试

其实就是本地文件缓存改为 8M？

和2楼说的正好相反。到底缓存开的大好还不开好？

都试试吧，我没试出来…………莫名出现，莫名消失

Cherrot · **发表于 :** 2012-05-22 18:17

那是不是开了mpeg多线程解码？
本地缓存还是不要的好，否则调整进度条会导致很卡。 mpeg如果使用多线程解码的话会出现闪烁现象，不论是几个线程。

从没去动过什么多线程，我是默认的啊

顿的时候终端有什么输出吗？

franklin2k · **发表于 :** 2012-05-23 14:09

顿的时候终端没有任何输出。我是播放移动硬盘上的视频。是不是播放移动硬盘的视频都这样？

终端输出如下：

是的，ntfs读得慢

franklin2k · **发表于 :** 2012-05-23 14:27

那要如何解决. 好像网上说 ubuntu 读写 ntfs 也不是很慢啊，不至于播放rmvb都卡吧

franklin2k · **发表于 :** 2012-05-23 14:44

usb移动硬盘的读写速度慢的总不至于播放 rmvb都卡吧？

/etc/mplayer/mplayer.conf、～/.mplayer/config这两个配置文件动过没，命令行怎么打的？
mplayer -v ... 看看更详细的输出？

不好意思，系统已经重装了。没法试。

重新安装了之后，还是会不定时的顿一下。问题依旧。看电影很不爽

求救！mplayer 播放一段时间后 ，就会顿一下，大概0.5秒钟。如何解决
