• Python video player using ffpyplayer.player with audio repeated cracking at end of clip

  18 janvier 2021, par sunyaer

  I am using the codes below to do a video player. For video clips cut using this command : "ffmpeg -i PrideAndPrejudice.mp4 -ss 00:50:31 -t 00:03:30 OutPutPP.mp4", there is audio crack that keeps repeating a couple of times when the picture stops at the end of the video. I suspect there may be some issues with the codes of QTimer, but as I am quite new to Python and ffmpeg, and can't figure out what exactly the problem is, not to mention how to fix it. Your help would be greatly appreciated.

  


      self.timer = QTimer()
    self.timer.setInterval(50)
    self.timer.start()
    self.timer.timeout.connect(self.showFrame)


  


  This is the whole codes :

  


   from ffpyplayer.player import MediaPlayer
 import sys
 from PyQt5.QtWidgets import *
 from PyQt5.QtGui import QPixmap, QImage, QImageReader
 from PyQt5.QtCore import QTimer

class MyApp(QWidget):
    def __init__(self, name, parent=None):
        super(MyApp, self).__init__(parent)
        self.label = QLabel()
        self.qimg = QImage()
        self.val = ''

        self.player = MediaPlayer("PrideAndPrejudice005030.mp4")
        self.timer = QTimer()
        self.timer.setInterval(50)
        self.timer.start()
        self.timer.timeout.connect(self.showFrame)

        layout = QVBoxLayout()
        layout.addWidget(self.label)
        self.setLayout(layout)
        self.setWindowTitle(name)

        # self.showFullScreen()

    def showFrame(self):
        frame, self.val = self.player.get_frame()
        if frame is not None:
            img, t = frame
            self.qimg = QImage(bytes(img.to_bytearray()[0]), img.get_size()[0], img.get_size()[1],
                               QImage.Format_RGB888)
            self.label.setPixmap(QPixmap.fromImage(self.qimg))


if __name__ == '__main__':
    app = QApplication(sys.argv)
    t = MyApp(sys.argv[0])
    t.show()
    sys.exit(app.exec_())
