• Heroku : [Errno 13] Permission Denied : /app/ffmpeg.exe

  4 mars 2021, par GetTwoBirdsStonedAtOnce

  So I made a python bot and I wanted to equip it with the ability to play music. I have been following this tutorial.

  


  Unfortunately when I run the play command I get the [Errno 13] Permission Denied: /app/ffmpeg.exe error. I have included the ffmpeg.exe file in my project branch as well as all of the ffmpeg files. I host this bot on heroku. I ran heroku logs --tail but this doesn't show me anything, I see the error as the output on a discord channel. Before you suggest it, I already have ran this : heroku config:set DISABLE_COLLECTSTATIC = 1. Of course to no avail... Here's the fragment of my code where I point to the ffmpeg.exe file :
return cls(discord.FFmpegPCMAudio(executable="/app/ffmpeg.exe", source = source), data=data, requester=ctx.author)

  


  Rest of the code is irrelevant as this is the only part that makes impact on the end result. Hope you can help me, cheers !

  


• Stream low latency RTSP video to android with ffmpeg

  21 octobre 2014, par grzebyk

  I am trying to stream live webcam video from Ubuntu 12.04 PC to android device with KitKat. So far I’ve written ffserver config file to receive ffm feed and broadcast it through a rtsp protocol. I am able to watch the stream on the other computer in the same LAN with ffplay.

  How to watch the stream on the android device ? The following code works well when the webcam image is streamed with vlc but it doesn’t with ffmpeg :

  public class MainActivity extends Activity implements MediaPlayer.OnPreparedListener,
  
          SurfaceHolder.Callback {
  
  
  
      final static String RTSP_URL = "rtsp://192.168.1.54:4424/test.sdp";
  
  
  
      private MediaPlayer _mediaPlayer;
  
      private SurfaceHolder _surfaceHolder;
  
  
  
      @Override
  
      protected void onCreate(Bundle savedInstanceState) {
  
          super.onCreate(savedInstanceState);
  
          // Set up a full-screen black window.
  
          requestWindowFeature(Window.FEATURE_NO_TITLE);
  
          Window window = getWindow();
  
          window.setFlags(
  
                  WindowManager.LayoutParams.FLAG_FULLSCREEN,
  
                  WindowManager.LayoutParams.FLAG_FULLSCREEN);
  
          window.setBackgroundDrawableResource(android.R.color.black);
  
          getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
  
          setContentView(R.layout.activity_main);
  
  
  
          // Configure the view that renders live video.
  
          SurfaceView videoView =
  
                  (SurfaceView) findViewById(R.id.videoView); //where R.id.videoView is a simple SurfaceView element in the layout xml file
  
          _surfaceHolder = videoView.getHolder();
  
          _surfaceHolder.addCallback(this);
  
          _surfaceHolder.setFixedSize(320, 240);
  
      }
  
      @Override
  
      public void surfaceCreated(SurfaceHolder surfaceHolder) {
  
          _mediaPlayer = new MediaPlayer();
  
          _mediaPlayer.setDisplay(_surfaceHolder);
  
          Context context = getApplicationContext();
  
          Uri source = Uri.parse(RTSP_URL);
  
          try {
  
              // Specify the IP camera's URL and auth headers.
  
              _mediaPlayer.setDataSource(context, source);
  
  
  
              // Begin the process of setting up a video stream.
  
              _mediaPlayer.setOnPreparedListener(this);
  
              _mediaPlayer.prepareAsync();
  
          }
  
          catch (Exception e) {}
  
      }
  
      @Override
  
      public void onPrepared(MediaPlayer mediaPlayer) {
  
          _mediaPlayer.start();
  
      }
  
  }

  My ffserver.config file :

  HTTPPort 8090
  
  RTSPBindAddress 0.0.0.0
  
  RTSPPort 4424
  
  MaxBandwidth 10000
  
  CustomLog -

          File /tmp/feed1.ffm
  
          FileMaxSize 20M
  
          ACL allow 127.0.0.1
  
  </feed>
  
  <stream>
  
      Feed feed1.ffm
  
      Format rtp  
  
      VideoCodec libx264
  
      VideoSize 640x480

      AVOptionVideo me_range 16
  
      AVOptionVideo qdiff 4
  
      AVOptionVideo qmin 10
  
      AVOptionVideo qmax 51
  
      Noaudio
  
      ACL allow localhost
  
          ACL allow 192.168.0.0 192.168.255.255
  
  </stream>

  I am starting the stream with this command : ffmpeg -f v4l2 -i /dev/video0 -c:v libx264 -b:v 600k http://localhost:8090/feed1.ffm
