[PyQt] PyQT5: Unable to render videos

[Rob]

Hi,

Bit more info on here with a simple test case. I've found that I can get a
video to playback if it's served over http but the same file won't play if
referenced locally. So at least it's a step in the right direction!

from PyQt5.QtMultimediaWidgets import QVideoWidget

class Example(QMainWindow):
    
    def __init__(self):
        super().__init__()
        
        self.initUI()
        
        
    def initUI(self):

        self.player = QMediaPlayer()
        
        # local file, fails to play:
        # error code 1 - ResourceError - A media resource couldn't be
resolved.
        # MediaStatus code 8 - InvalidMedia - The current media cannot be
played. The player is in the StoppedState.
        p =
QMediaContent(QUrl.fromLocalFile('C:\\Users\\rob\\Downloads\\Red_Dancing.wmv'))

        # Same file served using Node http-server works
        p = QMediaContent(QUrl('http://localhost:8080/Red_Dancing.wmv'))
        
        self.player.setMedia(p)
        self.player.setVolume(50)

        self.player.error.connect(self.error)
        self.player.mediaStatusChanged.connect(self.mediaStatus)
        self.player.bufferStatusChanged.connect(self.bufferStatus)

        self.videoWidget = QVideoWidget();
        self.player.setVideoOutput(self.videoWidget);
        self.setCentralWidget(self.videoWidget)
        self.videoWidget.show();
        
        self.player.pause()
        
        self.setGeometry(300, 300, 350, 250)
        self.setWindowTitle('Video')
        self.show()

    def error(self, e):
        print('error', e)

    def mediaStatus(self, e):
        print('mediaStatus', e)
        if e == 6 or e == 7: self.player.play()

    def bufferStatus(self, e):
        print('bufferStatus', e)

    def closeEvent(self, event):
        self.player.stop()
        self.player.setParent(None)
        self.player.deleteLater()
        self.player = None

        
if __name__ == '__main__':

    app = QApplication(sys.argv)
    ex = Example()
    sys.exit(app.exec_())

That code works with mp4 and wmv files when running over http although the
buffer time is much worse with the mp4 as is the looping.

Would really appreciate any thoughts.

Cheers,
Rob
