Ubuntu14.10GStreer1.4.3 h264parse缺失？

Question

你好，我刚刚将我的操作系统从14.04升级到14.10，当我看到gstreamer的新版本时，我非常兴奋，但问题是缺少了h264parse元素。我尝试重新安装gStreamer1.0-插件-坏，但什么都没有。当我使用解码时，它会自动使用vaapiparse_h264，当我尝试运行管道时，我得到了这个错误：

设置管道播放..。

这是包装问题还是我做错了什么？

根据http://gstreamer-devel.966125.n4.nabble.com/h264parse-has-been-removed-from-gstreamer-1-0-td4671468.html的说法，h264parse过滤器现在是libgstvideoparsersbad的一部分。

我已经确保安装了gstreamer1.0-plugins-bad-videoparsers，现在一切都正常了。过滤器本身被重命名为‘legacyh264解析’，但是旧名称有一个别名，所以它应该可以工作。
