Phonon::GStreamer::Backend: Failed to initialize GStreamer
遇到这个问题，完整问题如下：
root@beagleboard:~# ./qt -qws
init device manager under Poweron phase
"Warning: You do not seem to have the base GStreamer plugins installed.
  All audio and video support has been disabled"
Phonon::GStreamer::Backend: Failed to initialize GStreamer

(<unknown>:1873): GStreamer-CRITICAL **: gst_object_ref: assertion `object != NULL' failed

(<unknown>:1873): GStreamer-CRITICAL **: gst_object_sink: assertion `GST_IS_OBJECT (object)' failed

我之前运行这个程序都没有说要用到GStreamer，现在突然说GStreamer没装好，我直接将DVSDK里面的所有libgst* 库开呗过去了也不行。求交流···

------解决方案--------------------
你交叉编译了glib gstreamer等库了吗？我交叉编译了还是遇到这个问题。不知道是不是板子上需要什么环境变量？
------解决方案--------------------
也可能挎过去时路径不对。
