刚发现mplayer的一种用法！

llc

呵呵,我也有这个电影,mplayer真是越玩越有趣

我安装了下的那两个rpm包，但是在./configure --enable-gui时，里面没有Cheking aalib 这种字样。./configure 完成后，也没有enable plugins :Video Output 这个东东。（可能是我不知在哪里看吧。但是我执行了./configure这个命令之后，的确找不到你所提到的东东。）
编译完成后，（分别执行./configure --enable-gui;make;make install后，不知还有没有什么要执行，我以前安装过mplayer的)，可以正常播放多媒体文件，但是还是在命令符下是这样的错误。

不知要修改些什么？或我的安装有问题？

你想用ascii字符输出的话,应该用aa视频模式
刚才我自己又试了一下,vesa模式竟然也用不了了,我用老内核和模块也试过了,还是不行,不知是否是这个版本的问题

Kuye

哦，这样？！
在播放时要使用 mplayer -vo aa 才可以用 ascii模式播放，用 mplayer -vo help 里看一下有没有 aa，如果没有，可能是你安装有错误；
我在 Configure 时有一行：

怎么让aa播放为彩色字符啊？黑白的看着还是不很清楚。

gugong，你看看我的fbshot怎么出错了，控制台下抓不了屏啊：

[code:1]
#fbshot -c 1 test.jpg
An error occured: ioctl FBIOGET_FSCREENINFO Bad file descriptor

我的vesa也不行,fbdev可以,而且播放xvid格式的DVD-Rip很流畅.
mplayer和framebuffer都很强呀!  


成龙的燕尾服,手头就这一个DVD-Rip的.

llc

DGA模式也很快,全屏(只能是全屏,DGA模式无法窗口)模式图像很不错,速度也是飞快,和xv模式有得比,不过,需要XF86Config里关于分辨率定义段的配合才行

clfls

文本模式下怎么全屏??

kailin

我的也是可以的啊!

luoda

这个问题，我早就提过了，那个时候我的 vesa和fbdev都有问题．

linuxlilo

是不是字符界面下的抓屏工具?
字符界面的抓屏工具有哪些?
谢谢!

我的也是这样的,怎么回事?

好象与/dev/fb0设备有关,我的mplayer -vo fbdev file显示不能打开设备/dev/fb0,
请问这是怎么回事?
