video编解码器依赖不符合？
可能重复：
如何解决未满足的依赖项？
在尝试运行.M4A和.MP4之后（它们不是一样吗？）我收到一条消息，说我需要安装额外的编解码器。 尝试执行此操作时，我会收到一个错误窗口，指出编解码器的“依赖性未满足”。 错误报告是这样的：以下包具有未满足的依赖项：
gstreamer0.10-ffmpeg: Depends: libavcodec-extra-53 (>= 4:0.7.3-1) but
4:0.8.3ubuntu0.12.04.1 is to be installed

如果您正在运行Ubuntu 32位，请在终端上运行：
sudo apt-get -y install gstreamer0.10-pitfdll gstreamer0.10-ffmpeg gstreamer0.10-plugins-bad gstreamer0.10-plugins-bad-multiverse gstreamer0.10-plugins-ugly gstreamer0.10-plugins-ugly-multiverse
如果您正在运行Ubuntu 64位，请在终端上运行：
sudo apt-get -y install gstreamer0.10-ffmpeg gstreamer0.10-plugins-bad gstreamer0.10-plugins-bad-multiverse gstreamer0.10-plugins-ugly gstreamer0.10-plugins-ugly-multiverse
首先运行sudo apt-get update 。
然后你就可以成功安装gstreamer插件了。
正如@ThiagoPonte所说，安装所有gstreamer软件包，因此您不需要再次安装额外的编解码器。
还要检查类似的问题： Ubuntu 12.04中的Unmet依赖项？
首先通过终端中的follwing命令更新系统
sudo apt-get update
使用修复依赖项
sudo apt-get install -f
