• Discord FFMPEG audio wont play from yt-dlp

  19 mars 2023, par user21236822

  My question is this : Why isn't my bot playing audio ?

  


  I want the bot to join, play audio from queue, then disconnect without downloading an mp3 file.

  


  I tried using youtube-dl, but I switched to the yt-dlp library after getting errors I couldn't fix.
I am running on Windows 10 locally. All my libraries are up to date.

  


  Here are my ydl_opts and FFMPEG_OPTS :

  


  ydl_opts = {
    'format': 'bestaudio/best',
    'postprocessors': [{
        'key': 'FFmpegExtractAudio',
        'preferredcodec': 'mp3',
        'preferredquality': '192',
    }],
}

FFMPEG_OPTIONS = {
    'before_options': '-reconnect 1 -reconnect_streamed 1 -reconnect_delay_max 5',
    'options': '-vn'
} 


  


  Here is where I believe the problem is.

  


  async def play():
    print("Play Called")
    musicPlay()
    # Get message object from initial request
    message = ytLinkQue.get()
    print(f"Message object recieved: {message}")
    voiceChannel = message.author.voice.channel
    vc = await voiceChannel.connect()
    songsPlayed = 0
    
    while not ytLinkQue.empty():
        # Get current song
        currentSong = ytLinkQue.get()[0]
        print(f"Current song: {currentSong}")

        # Get song from Youtube
        with yt_dlp.YoutubeDL(ydl_opts) as ydl:
            # song = ydl.download(currentSong)
            info = ydl.extract_info(currentSong, download=False)
            song = info['formats'][0]['url']

        # Play Song
        vc.play(discord.FFmpegPCMAudio(song, **FFMPEG_OPTIONS), after=lambda e: print('Song done'))

        # Wait until the song has finished playing
        while vc.is_playing():
            print("playing rn")
            await asyncio.sleep(1)
    
    await vc.disconnect()
    musicStop()


  


  When play() is called, here is the output in terminal with my annotations as **** text **** :

  On Discord's end, the bot successfully connects then disconnects after 2 second.

  


  Note : I've only included code I think is relevant. Please let me know if I should add anything else to the post, otherwise, here is the github for the project. Code is in main.py.

  Thank you in advance !

  


  I've applied the advice from these posts but it still will not play audio :

• How do I correctly convert .avi to .flv with ffmpeg ? [closed]

  25 septembre 2012, par terbooter

  UPDATE
  Shame on me )
  I chacked red5 logs again and found that I placed converted files to wrong place.
  Now all works fine

  I have two red5 apps.

  1. Recorder. It can record live stream and save it to flv file to disk

     private void startRecord(String uid, String name, IConnection connection) {
     
         // Get a reference to the current broadcast stream.
     
         ClientBroadcastStream stream = (ClientBroadcastStream) this.getBroadcastStream(
     
                 connection.getScope(), name);
     
         try {
     
             // Save the stream to disk.
     
             String path = uid + "/" + name;
     
             stream.saveAs(path, true);
     
     
     
             System.out.println("file..:" + stream.getSaveFilename());
     
     
     
         } catch (Exception e) {
     
             System.out.println("Error while saving stream: " + name + e);
     
         }
     
     }
     
     
     
     private void stopRecord(String name) {
     
         IConnection conn = Red5.getConnectionLocal();
     
         System.out.println("Stop recording show for: {}" + conn.getScope().getContextPath());
     
     
     
         ClientBroadcastStream stream = (ClientBroadcastStream) this.getBroadcastStream(conn.getScope(), name);
     
         // Stop recording.
     
         if (stream != null) {
     
             stream.stopRecording();
     
         }
     
     }

  2. Second red5 app (Chat) streams recorded flv file to flash client

     public static String serverStreamCreate(String path, String streamName) {
     
     
     
         IServerStream serverStream = StreamUtils.createServerStream(Red5.getConnectionLocal().getScope(), streamName);
     
         SimplePlayItem item = SimplePlayItem.build(path);
     
     
     
         IPlaylistController controller = new MyPlayListController();
     
     
     
         serverStream.setPlaylistController(controller);
     
         serverStream.setRepeat(false);
     
         serverStream.addItem(item);
     
         serverStream.addItem(item);
     
         serverStream.start();
     
         return streamName;
     
     }

  If I record stream from flash client to flv file with Recorder and after that stream this flv file back to client with Chat, all works fine.

  Now I want to convert avi file to flv and stream it from red5 app to flash client.
  I used ffmpeg

  ffmpeg -i 24.avi -ar 22050 -an -f flv -b 500k -s 320x240 -y 24_c.flv

  But if I stream 24_c.flv from Chat app flash client have no video.
  24_c.flv cant be playd by VLC player and have same code information as flv file created by Recorder red5 app.

  I really dont know where to dig.

• Loading privacy policy file from RED5 server

  17 juillet 2013, par Yaron U.

  I have an IP camera that I need to connect to Flash/Air application (showing the stream),
  And then capturing data from the video into bitmap

  In order to do so I use RED5 server to serve the RTMP stream along with FFMPEG (to convert the camera's RTSP stream to RTMP)

  I made the conversion based on this very useful blog post

  Everything works fine (I can see the stream in the flash app) until I try to capture the video screen using BitmapData

  The error is about privacy policy file not loaded :

  Security sandbox violation: BitmapData.draw ... 
  
  cannot access rtmp://localhost:1935/live. No policy files granted access.
  
  ...

  Digging a little bit into RED5's config I see it has configurations for policy server on port 843 - but after luanching the server, it doesn't seem like it listens to this port
  and

  Any ideas ?
