  How to stream an MP4 video in Android from a server ? Here is my code but it only works for KitKat.

   private void play() {
  
              try {
  
                  final String path = ""
  
                  Log.v(TAG, "path: " + path);
  
                  if (path == null || path.length() == 0) {
  
                      Toast.makeText(getApplicationContext(), "File URL/path is empty",
  
                              Toast.LENGTH_LONG).show();
  
  
  
                  } else {
  
                      // If the path has not changed, just start the media player
  
                      if (path.equals(current) && mVideoView != null) {
  
  
  
                          mVideoView.start();
  
                          mVideoView.requestFocus();
  
                          return;
  
                      }
  
                      current = path;
  
                      mVideoView.setVideoPath(getDataSource(path));
  
  
  
                      mVideoView.start();
  
                      mVideoView.requestFocus();
  
  
  
                  }
  
              } catch (Exception e) {
  
                  Log.e(TAG, "error: " + e.getMessage(), e);
  
                  if (mVideoView != null) {
  
                      mVideoView.stopPlayback();
  
                  }
  
              }
  
          }
  
  
  
          private String getDataSource(String path) throws IOException {
  
              if (!URLUtil.isNetworkUrl(path)) {
  
                  return path;
  
              } else {
  
                  URL url = new URL(path);
  
                  URLConnection cn = url.openConnection();
  
                  cn.connect();
  
                  InputStream stream = cn.getInputStream();
  
                  if (stream == null)
  
                      throw new RuntimeException("stream is null");
  
                  File temp = File.createTempFile("mediaplayertmp", "dat");
  
                  temp.deleteOnExit();
  
                  String tempPath = temp.getAbsolutePath();
  
                  FileOutputStream out = new FileOutputStream(temp);
  
                  byte buf[] = new byte[256];
  
                  do {
  
                      int numread = stream.read(buf);
  
                      if (numread <= 0)
  
                          break;
  
                      out.write(buf, 0, numread);
  
                  } while (true);
  
                  try {
  
                      stream.close();

                  }

• FFmpeg Live Stream - Loop Video ?

  28 septembre 2019, par Dread-Eye

  I am trying to stream a video loop to justin.tv using FFmpeg ? I have managed to loop an image sequence and combine it with line in audio :

  ffmpeg -loop 1 -i imageSequence%04d.jpg -f alsa -ac 2 -ar 22050 -ab 64k \
    -i pulse -acodec adpcm_swf -r 10 -vcodec flv \
    -f flv rtmp ://live.justin.tv/app/
  

  Is it possible to do this with a video file ?

• Clipping audio problem on ffmpeg live stream

  20 mars 2019, par Ivan Bombash Stokic

  in 30-40% of the live stream i get some king of distortion or clipping in the streamed audio and i have no idea why, is is only because low hardware performance maybe ? I am running the stream on a Raspberry pi 3b+ CPU usage while streaming from 25 to 30% Ram usage 28% , storage device is a USB pen drive.

  Here is the code :

  ffmpeg -re -f alsa -i default -re -stream_loop -1 -i "/home/pi/Documents/Youtube/video720p.mp4" -c:v copy -c:a aac -f flv -max_muxing_queue_size 400 rtmp://a.rtmp.youtube.com/live2/pfjd-jhjs-k3td-xxxx

  Or i should buffer it before streaming or re-encode the audio before streaming ?

  Thanks in advance !
