• How to convert raw camera Android data into usual mpeg4 by ffmpeg ?

  12 octobre 2014, par trololo

  I can recieve raw camera data :

   fos = new FileOutputStream (new File(Environment.getExternalStorageDirectory().getPath() + "/video_raw.raw"));
  
  _.mCamera.setPreviewCallback(new Camera.PreviewCallback() {
  
        public synchronized void onPreviewFrame(byte[] data, Camera camera) {
  
  
  
              try {
  
                  if (fos != null)
  
                      fos.write(data);//I can save data to a file
  
  //Environment.getExternalStorageDirectory().getPath() + "/video_raw.raw"
  
                  } catch (IOException e1) {
  
                  // TODO Auto-generated catch block
  
                  e1.printStackTrace();
  
              }
  
  
  
            try{
  
                camera.addCallbackBuffer(data);
  
            }catch (Exception e) {
  
                Log.e("CameraTest", "addCallbackBuffer error");
  
                return;
  
            }
  
            return;
  
        }
  
    });

  and trying to use this library to manipulate with video(audio)-data

  File dir =  new File(_.mediaFile).getParentFile();
  
              FfmpegController fc = new FfmpegController(this, dir);
  
              Clip clip_in = new Clip(Environment.getExternalStorageDirectory().getPath() + "/video_raw.raw");
  
              clip_in.height = 480;
  
              clip_in.width = 720;
  
              clip_in.videoCodec = "rawvideo";
  
              clip_in.videoFilter= "rawvideo";
  
              Clip clip_out = new Clip(Environment.getExternalStorageDirectory().getPath() + "/video15a.mp4");
  
               //put flags in clip
  
              clip_out.videoFps = "30";
  
              clip_out.width = 480;
  
              clip_out.height = 320;
  
              clip_out.videoCodec = "libx264";
  
              clip_out.audioCodec = "copy";
  
              fc.processVideo(clip_in, clip_out, false, new ShellUtils.ShellCallback() {
  
              @Override
  
              public void shellOut(String shellLine) {
  
                  System.out.println("MIX> " + shellLine);
  
              }
  
  
  
              @Override
  
              public void processComplete(int exitValue) {
  
  
  
                  if (exitValue != 0) {
  
                      System.err.println("concat non-zero exit: " + exitValue);
  
                      Log.d("ffmpeg","Compilation error. FFmpeg failed");
  
                      Toast.makeText(AMain.this, "result: ffmpeg failed", Toast.LENGTH_LONG).show();
  
                  } else {
  
                  }
  
              }
  
          });

• Re streaming an rtsp stream from an ONVIF camera

  12 avril 2013, par user132151

  I would like to take the video stream from my ONVIF TI camera and add audio to the Moët stream.
  So I have the camera and I have a beagle board xm . On the beagle board I would like to suck in the h.264 rtsp stream, then I want to take the audio in from the beagle board and make 1 mpeg stream with audio and video.
  So I think I could do it with gstreamer, since you seem to be able to do everything audio video with gstreamer. But I'm a gstreamer virgin. But I'm not wedded to gstreamer I have a feeling you could probably do it in ffmpeg as well. But I would appreciate any help at all, particularly what commands I give to gstreamer to make it work
  So I have my beagle board that is currently running Ubuntu 12. Happy to use angstrom as well. It's on say 192.168.1.4. And my camera is in 192.168.1.6

• Reading from IP Camera (RTSP) using FFmpeg results in 5xx Server Error

  9 décembre 2015, par bcop

  I have a scenario where I am trying to read from IP camera using RTSP method.

  On my development PC everything is working fine, the rtsp url is something like :

  rtsp://admin:12345@192.168.1.60:554

  but when I try to test it over a friend’s place, he has different camera (Axis IP camera), and the url fails to open.
  The self generated log is something like :

  Error: avformat_open_input()
  
  error message: Server returned 5XX Server Error reply

  I tried opening it using HTTP tunneling, but this time I’m getting a different error :

  error message: Error number -5 occurred

  The latter error message even appears on my dev PC (just to mention that I tried this as well) ; so HTTP tunnel is no good.

  Any one knows how to fix 5XX Server Error ?

  Thanks,
