如何将 VLC 实例插入 QFrame [英] How to insert VLC instance into a QFrame

问题描述

我正在尝试通过在 PyQt 小部件(QFrame)中嵌入 VLC 实例来制作一个简单的视频播放器应用程序.我找到了一些可以帮助我的示例，但是我的代码不太好用.当我启动它时，它会播放test_video.mp4"，但它会在自己的单独窗口中启动常规 VLC 播放器应用程序.当我关闭 VLC 播放器窗口时，显然视频停止了，但音频继续播放，直到我关闭我自己的 Qt (PyQt) 窗口.

I'm trying to make a simple video player app by embedding a VLC instance inside a PyQt widget (a QFrame). I found a few examples that go me going, but my code doesn't quite work. When I launch it, it plays "test_video.mp4", but it launches the regular VLC player app in its own, separate window. When I close out of the VLC player window, obviously the video stops, but the audio continues playing until I close my own Qt (PyQt) window.

编辑 1:忘记提及我使用的是 python-vlc，通过 pip 下载.

    ### video_player.py

    import sys
    import vlc
    from PyQt4 import QtCore, QtGui
    from video_player_main_window import Ui_MainWindow

    class StartQT4(QtGui.QMainWindow):
        def __init__(self, parent=None):
            QtGui.QWidget.__init__(self, parent)
            self.ui = Ui_MainWindow()
            self.ui.setupUi(self)

            self.vlc_instance = vlc.Instance("--no-xlib --sout-all")
            self.mediaplayer = self.vlc_instance.media_player_new()
            self.mediaplayer.set_xwindow(self.ui.video_frame.winId())
            print(self.ui.video_frame.winId())
            self.media_path = "test_video.mp4"
            self.media = self.vlc_instance.media_new(self.media_path)
            self.mediaplayer = self.vlc_instance.media_player_new()
            self.mediaplayer.set_media(self.media)
            self.mediaplayer.play()

    if __name__ == "__main__":
        app = QtGui.QApplication(sys.argv)
        myapp = StartQT4()
        myapp.show()
        sys.exit(app.exec_())

我添加了一个print(self.ui.video_frame.win())"只是为了调试/健全性检查以确保这是一个合法的值.命令行输出如下.在我的 PyQt 窗口仍在运行时关闭 VLC 窗口后出现X 服务器故障".

I added a "print(self.ui.video_frame.win())" just for debugging / sanity check to make sure that was a legitimate value. Command line output below. The "X server failure" shows up after I close the VLC window while my PyQt window is still running.

### command line output

106954771
[00007f9c48055168] vdpau_avcodec generic error: Xlib is required for VDPAU
[00007f9c3c003968] xcb_window window error: X server failure

video_player_main_window"是QtDesigner (+ pyuic4) 生成的模块.video_frame"是我试图将 VLC 实例放入的 QFrame 对象的名称.在此处查看 video_player_main_window.py 的完整代码:http://pastebin.com/cHpAHZN2

The "video_player_main_window" is the module that QtDesigner (+ pyuic4) generates. "video_frame" is the name of the QFrame object I'm trying to put the VLC instance into. See full code for video_player_main_window.py here: http://pastebin.com/cHpAHZN2

推荐答案

如果这样 :

 import sys
 import vlc
 from PyQt4 import QtCore, QtGui
 from video_player_main_window import Ui_MainWindow

 class StartQT4(QtGui.QMainWindow):
     def __init__(self, parent=None):
         QtGui.QWidget.__init__(self, parent)
         self.ui = Ui_MainWindow()
         self.ui.setupUi(self)

         self.vlc_instance = vlc.Instance()
         self.mediaplayer = self.vlc_instance.media_player_new()
         self.mediaplayer.set_hwnd(int(self.frame.winId()))
         self.media_path = "test_video.mp4"
         self.media = self.vlc_instance.media_new(self.media_path)
         self.media.get_mrl()
         self.mediaplayer.set_media(self.media)
         self.mediaplayer.play()

if __name__ == "__main__":
    app = QtGui.QApplication(sys.argv)
    myapp = StartQT4()
    myapp.show()
    sys.exit(app.exec_())

我通常将它用于我的简单播放器.

i usualy use this for my simple player.
