我电脑里的所有视频文件都可以播放ffplay，vlc不能播放，是扼杀视频文件。
这是我的一些 vlc 配置。
我的电脑上的vlc在打开视频文件时会自动退出，这是怎么回事？是否有包裹丢失？
如何检查呢？
dpkg -l | grep vlc

在我的电脑上执行以下三个命令没有用。
sudo /usr/lib/vlc/vlc-cache-gen -f usr/lib/vlc/plugins
sudo apt-get update
sudo apt-get install --reinstall vlc
smplayer也安装了，两者都不能播放视频，当播放视频时，smplayer输出错误如下。

- MPlayer crashed by bad usage of CPU/FPU/RAM.
Recompile MPlayer with --enable-debug and make a 'gdb' backtrace and
disassembly. Details in DOCS/HTML/en/bugreports_what.html#bugreports_crash.
- MPlayer crashed. This shouldn't happen.
It can be a bug in the MPlayer code _or_ in your drivers _or_ in your
gcc version. If you think it's MPlayer's fault, please read
DOCS/HTML/en/bugreports.html and follow the instructions there. We can't and
won't help unless you provide this information when reporting a possible bug.

这个问题让我想起了一些可能导致此问题的问题：
1）vlc 中是否启用了视频？
- 工具 -> 首选项 -> 视频选项卡
- 查看启用视频框是否被选中，如果没有则启用它。
- 查看Windowdecorations是否勾选，如果没有勾选则。
- 将输出下拉菜单设置为 X11 视频输出 (XCB)。
2)从torrent下载视频文件时，有时可能会显示错误的100%下载，并且文件已损坏且无法播放。
3)如果mplayer也无法播放该视频，请检查其他视频文件。
4）重新安装vlc有时会弄乱事情，我建议这样做：
sudo apt-get update
sudo apt-get remove --purge vlc
sudo apt-get install vlc
5) 工具 -> 首选项 -> Codecs 下的输入/编解码器，如果“硬件加速解码”为“禁用”，请将其编辑为“自动”。
