  14 février 2017, par devxcon

  I am trying use ffmpeg in android. Here is the code so far. I took reference from this project. It just lets me convert video file. But I want to play a video file using ffmpeg. Is it possible ? If yes then how we can do that ?

• playing video in android using javacv ffmpeg

  20 février 2017, par d91

  I’m trying to play a video stored in sd card using javacv. Following is my code

  public class MainActivity extends AppCompatActivity {
  
  
  
      @Override
  
      protected void onCreate(Bundle savedInstanceState) {
  
          super.onCreate(savedInstanceState);
  
          setContentView(R.layout.activity_main);
  
          playthevideo();
  
      }
  
  
  
      protected void playthevideo() {
  
  
  
         String imageInSD = "/storage/080A-0063/dama/" + "test3.mp4";
  
  
  
         FFmpegFrameGrabber grabber = new FFmpegFrameGrabber(imageInSD);
  
  
  
         AndroidFrameConverter converterToBitmap = new AndroidFrameConverter();
  
  
  
         OpenCVFrameConverter.ToIplImage converterToipi = new OpenCVFrameConverter.ToIplImage();
  
  
  
             try {
  
                 Log.d("Tag", "try");
  
                 grabber.start();
  
                 Log.d("Tag", "started");
  
  
  
                 int i = 0;
  
                 IplImage grabbedImage = null;
  
  
  
                 ImageView mimg = (ImageView) findViewById(R.id.a);
  
  
  
                 grabber.setFrameRate(grabber.getFrameRate());
  
                 ArrayList<bitmap> bitmapArray = new ArrayList<bitmap>();
  
                 while (((grabbedImage = converterToipi.convert(grabber.grabImage())) != null)) {
  
  
  
                     Log.d("Tag", String.valueOf(i));
  
  
  
                     int width = grabbedImage.width();
  
  
  
                     int height = grabbedImage.height();
  
  
  
                     if (grabbedImage == null) {
  
                         Log.d("Tag", "error");
  
                     }
  
  
  
                     IplImage container = IplImage.create(width, height, IPL_DEPTH_8U, 4);
  
  
  
                     cvCvtColor(grabbedImage, container, CV_BGR2RGBA);
  
  
  
                     Bitmap bitmapnew = Bitmap.createBitmap(width, height, Bitmap.Config.ARGB_8888);
  
  
  
                     bitmapnew.copyPixelsFromBuffer(container.getByteBuffer());
  
  
  
                     if (bitmapnew == null) {
  
                         Log.d("Tag", "bit error");
  
                     }
  
  
  
                     mimg.setImageBitmap(bitmapnew);
  
  
  
                     mimg.requestFocus();
  
  
  
                     i++;
  
                 }
  
  
  
                 Log.d("Tag", "go");
  
  
  
             }
  
             catch(Exception e) {
  
  
  
            }
  
       }
  
  }
  
  </bitmap></bitmap>

  just ignore the tags because those are only for my testing purposes..
  When I run this code the main activity layout is still loading while android monitor shows the value of "i" (which is current frame number) and suddenly after frame number 3671 code exits the while loop and the imageview shows a frame which is not the end frame of that video(it somewhere around staring of the video).
  I was unable to find a way to show the grabbed frames from ffmpegframegrabber so i decided to show the image in imageview in this way. Can anybody tell me why I’m getting this error or another error non path to play and show the video in android activity ?
  BTW javacv 1.3.1 is imported correctly into my android dev environment. Thanks.

• FFMPEG Android Camera Streaming to RTMP

  2 février 2017, par Omer Abbas

  I need help for streaming android Camera using FFMPEG to a RTMP Server. I have compiled FFMPEG for android as a shared library. Everything from FFMPGEG side is working perfectly fine. I have tried to stream a already existed video file to RTMP and its working great. Then i have used Camera and write rawvideo to a file and stream it to RTMP server while writing camera rawvideo to the file, It’s also working but the issue is file size keep increasing. I have read about MediaRecorder LocalSocket that can stream data to ffmpeg as Unix Domain name local socket. I have used MediaRecorder Sample source of android sample https://github.com/googlesamples/android-MediaRecorder modified MediaRecorder to use local socket

  receiver = new LocalSocket();
  
      try {
  
  
  
          localSocketServer = new LocalServerSocket("camera2rtsp");
  
  
  
          // FileDescriptor the Camera can send to
  
          sender = localSocketServer.accept();
  
          sender.setReceiveBufferSize(500000);
  
          sender.setSendBufferSize(500000);
  
  
  
      } catch (IOException e1) {
  
          e1.printStackTrace();
  
          super.onResume();
  
          finish();
  
          //return;
  
      }
  
  
  
      mMediaRecorder.setOutputFile(sender.getFileDescriptor());

  Tried to access this socket with ffmpeg command, But it’s failed with the error unix ://camera2rtsp : no directory or file found.

  ffmpeg -i unix ://camera2rtsp -vcodec libx264 -f flv rtmp ://server

  so i tried ParcelFileDescriptor pipe

  pipe = getPipe();
  
  ParcelFileDescriptor parcelWrite  = new ParcelFileDescriptor(pipe[1]);
  
  mMediaRecorder.setOutputFile(parcelWrite.getFileDescriptor());

  With command

  "ffmpeg -re -r 30 -f rawvideo -i pipe :"+ pipe[0].getfd() +" -vcodec libx264 -f flv rtmp ://server"

  But it also not working, Seems like ffmpeg trying to read empty pipe and giving a warning of Size of Stream#0:0

  Also MediaRecorder with setOutputFile as ParcelFileDescriptor is giving error "E/MediaRecorder : start failed : -2147483648" in Galaxy S7 but working in a motorolla Phone with Kitkat.

  I might have been using Pipe or Socket Incorrectly Please if someone have any idea or experience of using ffmpeg stream with android camera please help me.

  I have figured out that MediaRecorder encode in MP4 format which is not seekable or streamable format because of headers or meta data.

  So i read a tutorial http://www.oodlestechnologies.com/blogs/Stream-video-from-camera-preview-to-wowza-server-in-Android this tutorial shows we can write raw video to a file and can pass this file to ffmpeg. It’s working great, But the issue is file size it increasing. So now my question is can i pass camera raw video to ffmpeg with ParcelFileDescriptor Pipe or LocalSocket ?

  Code :

  File f = new  File(Environment.getExternalStorageDirectory()+"/test.data");
  
                      if(!f.exists()){
  
                          f.createNewFile();
  
                      }
  
  
  
                      OutputStream outStream = new FileOutputStream(write);
  
  
  
                      Camera.Parameters parameters = mCamera.getParameters();
  
                      int imageFormat = parameters.getPreviewFormat();
  
                      if (imageFormat == ImageFormat.NV21) {
  
                          Camera.Size previewSize = parameters.getPreviewSize();
  
                          int frameWidth = previewSize.width;
  
                          int frameHeight = previewSize.height;
  
  
  
                          Rect rect = new Rect(0, 0, frameWidth, frameHeight);
  
                          YuvImage img = new YuvImage(arg0, ImageFormat.NV21, frameWidth, frameHeight, null);
  
  
  
                          outStream.write(arg0);
  
                          outStream.flush();
  
  
  
                          //img.compressToJpeg(rect, 50, processIn);
  
                      }
