gstreamer 版本号是多少?

[yatasun]

1.14.2-1

[bianjp]

有点奇怪，你执行这些语句看下输出：

import gi
gi.require_version('Gst', '1.0')
from gi.repository import Gst
print(Gst._version)
print(Gst.version_string())
print(Gst.init.__doc__)
print([a.get_name() + ":" + str(a.is_optional()) for a in Gst.init.get_arguments()])

[yatasun]

1.0 Traceback (most recent call last): File "/home/leave8426/ACM/test.py", line 5, in print(Gst.version_string()) File "/usr/lib/python3.6/site-packages/gi/overrides/Gst.py", line 589, in fake_method raise NotInitialized("Please call Gst.init(argv) before using GStreamer") gi.overrides.Gst.NotInitialized: Please call Gst.init(argv) before using GStreamer

看来 GObject 或 gstreamer 安装有问题。 什么发行版？什么版本？Python, GObject, gstream 都是怎么安装的？

[yatasun]

Manjaro 17.1.7 GNOME PyGoject : sudo pacman -S python-gobject python2-gobject gtk3 GStreamer : 作为另一个软件包的依赖而安装 Python 3.6.6.1 : 作为另一个软件包的依赖而安装

[bianjp]

我检查了下 Manjaro 的 python-gobject 包中并没有 /usr/lib/python3.6/site-packages/gi/overrides/Gst.py 这个文件。你看下这个文件是属于哪个包的：

pacman -Qo /usr/lib/python3.6/site-packages/gi/overrides/Gst.py

[yatasun]

/usr/lib/python3.6/site-packages/gi/overrides/Gst.py 由 gst-python 1.14.1-1 所拥有

[bianjp]

gst-python 由 GStreamer 官方团队维护，主页只是说 "overrides for the gobject-introspection-based pygst bindings" 却没说为什么要 override，也没说兼容性。

你可以暂时把 gst-python 卸载。我有空再好好考虑下是否有必要兼容 gst-python。

[yatasun]

卸载后可以启动。THX
