我的管道：

你好，我刚刚将操作系统从 14.04 升级到 14.10，当我看到新版本的 gstreamer 时，我很兴奋，但问题是缺少 h264parse 元素。我尝试重新安装 gstreamer1.0-plugins-bad，但没有成功。当我使用 decryptbin 时，它会自动使用 vaapiparse_h264，当我尝试运行管道时，我收到此错误：

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，该h264parse过滤器现在是 的一部分libgstvideoparsersbad。

我已确认已gstreamer1.0-plugins-bad-videoparsers安装，现在一切正常。过滤器本身已重命名为“legacyh264parse”，但旧名称有一个别名，因此它应该可以正常工作。
