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

  17 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. It would be greatly appreciated for your help.

  


      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_())


  


• Ffmpeg "no directory found" when passing in a path to the mp3 file

  21 février 2020, par Eugene Levinson

  How my code should work :

  Join the voice channel with the user who sent the command

  Download the video using the link

  Save it as random 16 digit number .mp3

  Then pass the path to the FFmpeg player to play

  My code :

  The random 16 digit number

  def get_digits(amount):
  
      st = ""
  
      for i in range(amount):
  
          n = random.randint(0,9)
  
          st = st + str(n)
  
  
  
      return int(st)

  Downloading the file

  def get_path(url):
  
  
  
      #checking if the directory exists
  
      os.makedirs('Music', exist_ok=True)
  
  
  
      title = YouTube(url).streams.get_highest_resolution().title
  
      current_directory = pathlib.Path(__file__).parent.absolute()
  
  
  
      print(str(current_directory))
  
  
  
      #name for the music
  
      name = str(get_digits(16))
  
  
  
      YouTube(url).streams.filter(only_audio=True).order_by("bitrate").desc().first().download("Music",name )
  
      return str(str(current_directory) + "/Music/" + name + ".mp3")

  This gets called on command play

  #function to connect to a voice chat
  
  async def join_auth(ctx):
  
      try:
  
          channel = ctx.author.voice.channel
  
          vc = await channel.connect()
  
          return vc
  
      except Exception as e:
  
          logg("Exception occured when joining a voice channel: " + str(e),"error",str(ctx.guild.name), str(ctx.guild.id))

  The error I get :
  C:\Users\Eugene\Desktop\Discord bot/Music/4343941300524002.mp3: No such file or directory
  But the directory C:\Users\Eugene\Desktop\Discord bot\Music exists and it does contain the 4343941300524002.mp3 file. Does anyone know why do I get the error ?

• Node js Rtsp stream get audio and video from different sources

  14 septembre 2020, par El Mantih Chaimae

  So I'm building a node js school streaming app that takes an IP cam stream and shows it on a web page , but I found problems with audio, so I thought i would be easier to connect a microphone with the device (computer) and combine the audio and video in one stream

  


  I'm using node-RTSP-stream, socket.io, FFmpeg and jsmpeg
