【问题描述】：
我按照https://kivy.org/docs/installation/installation-osx.html#using-pip上的说明进行操作
如果运行 kivy/examples/demo/kivycatalog/main.py 但是我得到了错误：
File "/Users/sonium/anaconda/lib/python3.4/site-packages/kivy/uix/video.py", line 171, in _do_video_load
self._video = CoreVideo(filename=filename, **self.options)
File "/Users/sonium/anaconda/lib/python3.4/site-packages/kivy/core/video/video_gstplayer.py", line 56, in __init__
super(VideoGstplayer, self).__init__(**kwargs)
File "/Users/sonium/anaconda/lib/python3.4/site-packages/kivy/core/video/__init__.py", line 83, in __init__
self.filename = kwargs.get('filename')

self.player.load()

kivy.lib.gstplayer._gstplayer.GstPlayerException: Unable to create a playbin
编辑： 该问题已通过“brew install gst-python”部分解决，但似乎需要已重命名为 gst-libav 的 gst-ffmpeg。播放视频仍然失败：
WARNING] [VideoGstplayer] b"No decoder available for type 'video/x-matroska'."
[ERROR ] [VideoGstplayer] b'Your GStreamer installation is missing a plug-in.'
[ERROR ] [VideoGstplayer] b'GStreamer encountered a general stream error.'

我会先尝试旧的 gst-launch-1.0 测试，例如从 shell 运行：
gst-launch-1.0 videotestsrc ! autovideosink如果您已正确安装 gstreamer..我不知道 kivy 如何安装/使用 gstreamer..跨度>
