• FFmpeg Android : Freezes / stops silently at 'SoundHandle'

  8 décembre 2014, par jgads

  I’m trying to get FFmpeg working on Android, but it seems to fail silently with no output file. I have tested the same command on Windows and it fully completes.

  I’m trying to convert an mp4 into a format which I can then ’concat’ with other videos files to make one ’compilation’ video.

  The command is :

  ffmpeg -i 1.mp4 -c copy -bsf h264_mp4toannexb -t 30 out1.ts

  The logcat shows that ffmpeg seems to get ’stuck’ - with no updates and seemingly quitting half way through. Is there anything obvious I’m doing wrong ? This is being tested on just a bog-standard Galaxy Note 2. ’ffmpeg -version’ works just fine.

  Here is the logcat :

• Issue in concatenating two video files using FFMPEG

  12 mai 2014, par intrepidkarthi

  I am trying to concatenate two mp4 files taken from gallery. I am getting issue with process execution failure. I have added the code and the error log. Using the ffmpeg library taken from guardian project.

  I am running this in Samsung Galaxy S3 device.

  The error is thrown in this particular line.

  ProcessBuilder pb = new ProcessBuilder(cmds);
  
  pb.directory(fileExec);
  
  Process process = pb.start();  

  When I replace the last line above with this,

  Process process = Runtime.getRuntime().exec("chmod 777 "+cmds.toArray(new String[cmds.size()]));

  It works with out the exception as shown below. But the output doesn’t seem to come.

  File concatenation Code :

      File fileVideoOutput = new File(getApplicationContext()
  
              .getExternalFilesDir("test") + "hello.mp4");
  
      fileVideoOutput.delete();
  
  
  
      File fileTmp = getApplicationContext().getCacheDir();
  
      File fileAppRoot = new File(getApplicationContext()
  
              .getApplicationInfo().dataDir);
  
  
  
      try {
  
          FfmpegController fc = new FfmpegController(fileTmp, fileAppRoot);
  
  
  
          ArrayList<clip> listVideos = new ArrayList<clip>();
  
          Clip clip = new Clip();
  
          clip.path = video1;
  
          fc.getInfo(clip);
  
          clip.duration = clip.duration;
  
          System.out.println("Clip1 duration " + clip.duration);
  
          listVideos.add(clip);
  
  
  
          Clip clip2 = new Clip();
  
          clip2.path = video2;
  
          fc.getInfo(clip2);
  
          clip2.duration = clip2.duration;
  
          System.out.println("Clip2 duration " + clip2.duration);
  
          listVideos.add(clip2);
  
  
  
          Clip clipOut = new Clip();
  
          clipOut.path = fileVideoOutput.getCanonicalPath();
  
  
  
          fc.concatAndTrimFilesMP4Stream(listVideos, clipOut, false, false,
  
                  new ShellUtils.ShellCallback() {
  
  
  
                      @Override
  
                      public void shellOut(String shellLine) {
  
  
  
                          System.out.println("fc>" + shellLine);
  
                      }
  
  
  
                      @Override
  
                      public void processComplete(int exitValue) {
  
  
  
                          if (exitValue &lt; 0)
  
                              System.err.println("concat non-zero exit: "
  
                                      + exitValue);
  
                      }
  
                  });
  
      } catch (Exception e1) {
  
          e1.printStackTrace();
  
      }
  
  </clip></clip>

  Here is my ffmpeg commands as given in the ffmpeg tutorial page.

  ffmpeg -i input1.mp4 -c copy -bsf:v h264_mp4toannexb -f mpegts intermediate1.ts
  
  ffmpeg -i input2.mp4 -c copy -bsf:v h264_mp4toannexb -f mpegts intermediate2.ts
  
  ffmpeg -i "concat:intermediate1.ts|intermediate2.ts" -c copy -bsf:a aac_adtstoasc output.mp4

  FFMPEG library doesn’t seem to be working as expected. When I add commands and create output file using "touch" shell command file is being created. Still I am unable to see the output from ffmpeg as expected.

• 3 seconds latency while streaming with Wowza Server

  18 mai 2015, par kaizen_labs

  I’m trying to develop a live streaming application with RTSP protocol.

  On the PC with the Wowza Server, I execute the following command :

  Code :

  ffmpeg -f dshow -i video="Name_Of_My_Cam":audio="Name_Of_My_Microphone" -vcodec
  
  h263p -f rtsp -muxdelay 0.1 rtsp://:1935/live/test

  And I’m trying to play this stream on a VideoView on my Samsung Galaxy Note 3 Lite. Here is the code :

  @Override
  
  protected void onCreate(Bundle savedInstanceState) {
  
      super.onCreate(savedInstanceState);
  
      setContentView(R.layout.activity_main);
  
  
  
      VideoView vv = (VideoView) findViewById(R.id.videoView);
  
      // Receive RTSP video from Wowza Server
  
      vv.setVideoURI(Uri.parse("rtsp://:1935/live/test"));
  
      vv.requestFocus();
  
      vv.start();
  
  }

  I managed to read the video and the sound but it makes 3 secondes (or more...) to start and I keep this delay during all the streaming. It is very annoying because I want to develop a call session.

  Does anybody know how to reduce this delay ? Is it a Wowza issue ?
