我的是64位的,32位的同学下载32的库文件.
1:下载13.10每日构建版
2:软件源里安装vdpau-va-driver,vdpauinfo,libvdpau1
3:下载 GPU 对应型号的 UVD Firmware 并放入到 /lib/firmware/radeon 目录，我的显卡是sumo,所以下载sumo_UVD.bin
地址: http://people.freedesktop.org/~agd5f/radeon_ucode/
4:下载libLLVM-3.3-4.1.x86_64.rpm里的所有so文件全部放进kubuntu里的/usr/lib/目录下.
5:从opensuse那里借来的libvdpau_r600-9.2.0-55.1.x86_64.rpm,解压后把so文件放入/usr/lib/vdpau/下,其中vdpau目录要你自己建.
6: 在/etc/ld.so.conf.d/里随便新建一个conf文件,比如vdpau.conf,打开这个空文件,里面加一句: /usr/lib/vdpau 即可.....重启或用命令sudo ldconfig激活一下
7:安装smplayer,输出驱动选择vdpau
8:Goodluck......
我们首先在终端下用命令vdpauinfo查看一下有没有正常输出
$ vdpauinfo

然后打开smplayer,先选用xv解码,作对比用,用任务管理器查看cpu占用情况:
电脑上看了下,居然都是rmvb格式的电影......找来找去只找到这个mkv格式的游戏视频......
用xv解码时cpu占用在7-13之间
用vdpau解码时,只有0-1的占用率,效率非常显著,哈哈
