vlc昨天还好用，今天打开mkv文件时闪一下就退出了。看了之前也有报错的，viewtopic.php?t=461626，但有所不同的是：我如果先进入vlc界面后，一打开mkv文件就退出。

换成smplayer能正常播放。

命令行输入vlc，并打开mkv文件报错为：

解决 Failed to open VDPAU backend libvdpau_i965.so
1. 调整 VLC 视频输出设置，详见
  https://wiki.archlinux.org/index.php/VL ... AU_backend
2. 安装 vdpauinfo，确认安装了 libvdpau-va-gl1 和 i965-va-driver
3. 运行 vdpauinfo 看是否提示相同错误？(Failed to open VDPAU backend libvdpau_i965.so)
4. 对于 amd64 架构系统
  代码：全选
```
sudo ln -s /usr/lib/x86_64-linux-gnu/vdpau/libvdpau_va_gl.so.1 /usr/lib/x86_64-linux-gnu/vdpau/libvdpau_i965.so.1
```
5. 编辑/创建 /etc/profile 和 /etc/xprofile，都加入以下内容
  代码：全选
```
export VDPAU_DRIVER=va_gl
```
6. 重新启动计算机
7. 运行 vdpauinfo 看错误是否消失？
  
  问题的根源是 intel 不支持 vdpau，没有任何包提供 libvdpau_i965.so。

如法操作，还是报错， purge vlc然后重装，还是遇到问题。索性在git上下载了源码编辑安装。补了几个包之后终于安装上了。运行时又报错：

卸载了编译安装：

代码：全选

make uninstall 
make distclean

再次从源安装vlc，这次启动正常，但打不开mkv文件。弹出错误窗口：

很久没用 vlc 了，刚刚试了下。
看来最近 debian testing 的环境对 vlc 不友好？我两台 testing 的机器，一台之前安装的 vlc 出现找不到 Qt 库 xcb 错误，重装无法解决。
另一台新安装了 vlc，播放闪退。错误和您的类似：

要不先暂时用 mpv / smplayer 顶一下？

发表于： **2015-10-30 13:36**

看来是testing带来的了问题无疑了。我也同时在用smplayer。不过觉着smplayer的皮肤太low了。

发表于： **2015-10-30 13:45**

以前没用过mpv，刚试了一下。感觉很酷，只是似乎没有菜单栏。打开文件需要拖放文件。这货看上去等待有人写插件的样子。另，vlc给卸了，不玩它了。

直接从文件管理器中打开视频即可。

配置文件 ~/.config/mpv/mpv.conf
参考 /usr/share/doc/mpv/example.conf 设置。

是否需要修改控件样式为 GTK+？

嗯，这样修改一下之后入眼多了。

期待及早修正，估计用不了一周吧。

今天更新源后重新安装了vlc，播放视频不再闪退了。但播放时却出现了卡顿，换成smplayer却是正常的。

在字符界面下运行vlc并播放视频出现如下信息：

问题的根源是 intel 不支持 vdpau，没有任何包提供 libvdpau_i965.so。

http://www.phoronix.com/forums/forum/so ... post470678
I have tried this on my kubuntu. It enables flash player and mplayer to make use of the hardware acceleration function on my ivy-bridge cpu. However, it lacks some minor functions available in VDPAU (e.g. denoise).

看看這個網頁

vaapi intel-driver - 1.6.1

補充
由 Intel 直接提供給 Linux 的開源 driver 及配套程式
主要分為
Intel Graphics Installer
及
Intel Graphics Stack Release
及
Intel Graphics Firmware
