• build-ffmpeg.sh bad variable name

  25 octobre 2016, par Alex Kombo

  I have added the library to my project successfully but after replacing the Android media player with the FFmpegMediaPlayer and trying to build and run the project, I get the following error :

  :library:buildFFmpeg
  
  /home/kombo/Radio Africa/Music Player/library/src/main/scripts/build-ffmpeg.sh: 4: export: Africa/Music: bad variable name
  
  
  
   FAILED
  
  
  
  FAILURE: Build failed with an exception.
  
  
  
  * What went wrong:
  
  Execution failed for task ':library:buildFFmpeg'.
  
  > Process 'command '/home/kombo/Radio Africa/Music Player/library/src/main/scripts/build-ffmpeg.sh'' finished with non-zero exit value 2

  BUILD FAILED

  How can I solve tackle this since removing the build-ffmpeg.sh file doesn’t look like an option.

• voiceclient.play(discord.FFmpegPCMAudio) doesn't play any audio

  23 septembre 2021, par mm3239

  I'm trying to create a private music bot. It joined voice channel, but no sound came out and queue didn't worked. My play function is like this :

  


  async def play_music(self):
    if len(self.music_queue) > 0:
        self.is_playing = True

        index = self.music_queue[0][0]['index']

        #connecting to voice channel
        if not self.vc.is_connected():
            self.vc = await self.music_queue[0][1].connect()
        else:
            await self.vc.move_to(self.music_queue[0][1])

        self.music_queue.pop(0)

        self.vc.play(discord.FFmpegPCMAudio(self.music_files[index], **self.FFMPEG_OPTIONS), after=lambda e: self.play_next())


  


  When I execute the file, it should work like this :

  


  Me: /play abc.mp3
Bot: Song added to queue.
*abc song plays in voice channel*
Me: /play def.mp3
Bot: Song added to queue.
Me: /play ghi.mp3
Bot: Song added to queue.

Me: /queue
Bot: def.mp3
     ghi.mp3


  


  However, in reality, Discord :

  


  Me: /play abc.mp3
Bot: Song added to queue.
*silence*
Me: /play def.mp3
Bot: Song added to queue.
Me: /play ghi.mp3
Bot: Song added to queue.

Me: /queue
Bot: No music in queue.


  


  Console :

  


  music found!&#xA;[[{&#x27;index&#x27;: 2, &#x27;title&#x27;: &#x27;abc.mp3&#x27;}, <voicechannel>]]&#xA;music found!&#xA;[[{&#x27;index&#x27;: 0, &#x27;title&#x27;: &#x27;def.mp3&#x27;}, <voicechannel>]]&#xA;&#xA;music found!&#xA;[[{&#x27;index&#x27;: 1, &#x27;title&#x27;: &#x27;ghi.mp3&#x27;}, <voicechannel> position=5 bitrate=64000 user_limit=10 category_id=790202432072187909>]]&#xA;</voicechannel></voicechannel></voicechannel>

  


  I can see something's wrong(abc and def prints shorter message in console, middle part of message is skipped), but as you can see, it doesn't raise any error or exception. Could anyone please help me correct my code ? I'm completely stuck, and it would be really appreciated if someone could tell me what the problem is.

  


• Cannot stream properly on YouTube using ffmpeg with Python

  1er mars 2018, par Francesco

  I have a few problems related to sending ffmpeg stream to YouTube.
  1. If I comment out "time.sleep(sleep_time)" the stream goes 3x fast(basing on what ?) ;
  2. If I uncomment the ’-r’ args the stream lags ;
  3. If I don’t add the background music the stream doesn’t start on YouTube, the problem persists if I uncomment the ’-an’ args.
  4. When the background music ends the stream stops working on YouTube.

  frame = cv2.imread('STATIC_IMAGE.jpg')
  
  fps = 25
  
  sleepTime = 1 / fps
  
  
  
  height, width, channels = frame.shape
  
  
  
  command = [
  
      'ffmpeg',
  
  
  
      #OpenCV image.
  
      #'-re',
  
      #'-threads', '0',
  
      '-f', 'rawvideo', #image2pipe
  
      '-vcodec','rawvideo',
  
      '-s', str(width) + 'x' + str(height),
  
      '-pixel_format', 'bgr24',
  
      #'-r', str(fps),
  
      #'-an',
  
      '-i', '-',
  
  
  
      #Background music
  
      #'-stream_loop', '-1',
  
      #'-re',
  
      #'-r', str(fps),
  
      '-i', 'music.mp3',
  
  
  
      #Output (actual stream)
  
      #'-r', str(fps),
  
      #'-crf', '25',
  
      #'-g', '39',
  
      #'-g', '2',
  
      #'-ac', '2',
  
      #'-c:a', 'aac',

      #'-b:v', '300k',
  
      #'-c:v', 'libx264',
  
      #'-bufsize', '600k',
  
      #'-maxrate', '300k',
  
      #'-qmin', '32',
  
      #'-qmax', '64',
  
      #'-vcodec', 'libx264',
  
      #'-pixel_format', 'yuv420p',
  
      '-vcodec', 'h264',
  
      '-pixel_format', 'h264',
  
      '-f', 'flv',
  
      'rtmp://a.rtmp.youtube.com/live2/STREAM_KEY'
  
  ]
  
  
  
  import subprocess as sp
  
  proc = sp.Popen(command, stdin=sp.PIPE, shell=False)
  
  
  
  while True:
  
      proc.stdin.write(frame.tostring())
  
  
  
      time.sleep(sleepTime)

  Any idea of why these problems happen ?
  May the "while True" be the problem ?
