kivy.lib.gstplayer._gstplayer.GstPlayerException：无法在Mac上创建Playbin

时间：2019-07-03 09:09:21

标签： python pycharm kivy gstreamer kivy-language

当我单击调用函数（v_player）播放公司视频的按钮时，出现此错误：

在kivy.lib.gstplayer._gstplayer.GstPlayer.load中的文件“ kivy / lib / gstplayer / _gstplayer.pyx”，第233行  kivy.lib.gstplayer._gstplayer.GstPlayerException：无法创建播放箱

我正在使用PyCharm（2019.1.1）在Mac（Mojave版本：10.14.5）上进行开发。

项目解释器：（Python 3.7） Cython 0.29.7 猕猴桃1.10.1 Kivy-Garden 0.1.4
Pygments 2.3.1
认证2019.3.9
chardet 3.0.4

pbxproj 2.5.1
点19.0.3 要求2.21.0 setuptools 40.8.0 urllib3 1.24.2 轮0.33.1

我已经检查了安装，更新或重新安装了软件包： gstreamer gst-plugins-base gst-plugins-good gst-plugins-bad gst-plugins-ugly

我也这样做了： （所做的工作是在我的kivy安装中删除了“ gstplayer”。在您进行kivy安装的地方是“ site-packages / kivy / lib / gstplayer”中的某些位置，请再次执行rm -R site-packages / kivy / lib / gstplayer，该路径应替换为本地安装路径。

基于本期在kivy github网站上的评论。该目录称为“ gstreamer”。在我的安装中，它被称为“ gstplayer”。） 而不适合我。

Ptyhon代码：

class Presentation(Screen):

    def v_player(self):
        if App.get_running_app().play == 0:
            App.get_running_app().play = 1
            App.get_running_app().video = Video(source='data/video/video.mp4')
            App.get_running_app().video.state = 'play'
            App.get_running_app().video.allow_stretch = True
            self.add_widget(App.get_running_app().video)
        else:
            App.get_running_app().play = 1

.kv代码：

        FloatLayout:
            ImageButton:
                source: 'data/icons/playback_play_icon48.png'
                size_hint: .5, .5
                pos_hint: {'center_y': 0.50, 'center_x': 0.50}
                on_press: root.v_player()

我在Google上已经读了很多书，重新安装了所有内容，并尝试了上述几种解决方案，但仍无法解决问题

有什么主意吗？ 预先感谢

如果我尝试使用此命令播放视频，我也会收到错误消息：

python3 -m kivy.uix.videoplayer Library/Python/3.7/share/kivy-examples/widgets/cityCC0.mpg

有什么想法吗？谢谢...

我已逐步调试，在错误跳出并挂起应用程序之前，我所看到的唯一问题是：

“ NoneType”对象没有属性“ get_duration”

在文件上：video_gsplayer.py 在sefl属性中：

duration: = {str} 'Traceback (most recent call last):\n File "/Aplications/PyCharm CE.app/Contents/helpers/pydev/_pydevd_bundle/pydevd_resolver.py", line 178, in _getPyDictionary\n'attr = getattr(var...

有什么主意吗？
