• Surface Texture object is not getting the frames from a Surface Class

  22 avril 2016, par Juan Manuel González Otero

  On the one hand, I have a Surface Class which when instantiated, automatically initialize a new thread and start grabbing frames from a streaming source via native code based on FFMPEG. Here is the main parts of the code for the aforementioned Surface Class :

   public class StreamingSurface extends Surface implements Runnable {
  
  
  
      ...
  
  
  
      public StreamingSurface(SurfaceTexture surfaceTexture, int width, int height) {
  
          super(surfaceTexture);
  
  
  
          screenWidth  = width;
  
          screenHeight = height;      
  
          init();
  
  
  
      }
  
  
  
      public void init() {
  
          mDrawTop = 0;
  
          mDrawLeft = 0;
  
          mVideoCurrentFrame = 0;
  
          this.setVideoFile();
  
          this.startPlay();
  
      }
  
  
  
      public void setVideoFile() {        
  
          // Initialise FFMPEG
  
          naInit("");
  
  
  
          // Get stream video res
  
          int[] res = naGetVideoRes();
  
          mDisplayWidth = (int)(res[0]);
  
          mDisplayHeight = (int)(res[1]);
  
  
  
          // Prepare Display
  
          mBitmap = Bitmap.createBitmap(mDisplayWidth, mDisplayHeight, Bitmap.Config.ARGB_8888);
  
          naPrepareDisplay(mBitmap, mDisplayWidth, mDisplayHeight);
  
      }
  
  
  
      public void startPlay() {
  
          thread = new Thread(this);
  
          thread.start(); 
  
      }
  
  
  
      @Override
  
      public void run() {
  
          while (true) {
  
              while (2 == mStatus) {
  
                  //pause
  
                  SystemClock.sleep(100);
  
              }
  
              mVideoCurrentFrame = naGetVideoFrame();
  
              if (0 < mVideoCurrentFrame) {
  
                  //success, redraw
  
                  if(isValid()){
  
                       Canvas canvas = lockCanvas(null);
  
                       if (null != mBitmap) {
  
                           canvas.drawBitmap(mBitmap, mDrawLeft, mDrawTop, prFramePaint);
  
                       }
  
                       unlockCanvasAndPost(canvas);
  
                  }
  
              } else {
  
                  //failure, probably end of video, break
  
                  naFinish(mBitmap);
  
                  mStatus = 0;
  
                  break;
  
              }
  
          }   
  
      }
  
  
  
  }

  In my MainActivity class, I instantiated this class in the following way :

  public void startCamera(int texture)
  
  {
  
      mSurface = new SurfaceTexture(texture);
  
      mSurface.setOnFrameAvailableListener(this); 
  
      Surface surface = new StreamingSurface(mSurface, 640, 360);
  
      surface.release();        
  
  }

  I read the following line in the Android developer page, regarding the Surface class constructor :

  "Images drawn to the Surface will be made available to the SurfaceTexture, which can attach them to an OpenGL ES texture via updateTexImage()."

  That is exactly what I want to do, and I have everything ready for the further renderization. But definitely, with the above code, I never get my frames captured in the surface class transformed to its corresponding SurfaceTexture. I know this because the debugger, for instace, never call the OnFrameAvailableLister method associated with that Surface Texture.

  Any ideas ? Maybe the fact that I am using a thread to call the drawing functions is messing everything ? In such a case, what alternatives I have to grab the frames ?

  Thanks in advance

• FFmpeg can't run in some device Android

  30 mars 2016, par tqn

  i’m working in a video processing project and now i’m using ffmpeg library in Android. I’m facing with a strange problem with asus zenphone 4 t00l (or all x86 device, I’ve just test in this x86 phone). When start command in project, app always crash :

  First, I think the problem is ffmpeg library. So I created a test module with simple activity just load and run command and there’re no problem.

  Second, I’m afraid that app cannot load version ffmpeg, because in my log, it’s armv7-neon althought it’s x86 (In my test module, it display x86). And according my search result, may be a external library make app to use abi arm (Build.CPU_API="armv7"). So I try remove all library in gradle in module Test and detected a library. But check in aar file of library, it support all x86 and arm. But after remove it, app still crash with same log. And strangely, althogh Test module register as arm but it’still run success (External question : Why add library jp.wasabeef:picasso-transformations make system register as armv7 although it’s x86)

  Finally, i think problem is command. But after debug, I use same command for Test module but it still success. Now i’m still stuck with it. Could anyone help me to solve it. Thanks. Here my demo code :

      String input = "/storage/emulated/0/Videa/Video/VIDEO_20160122_160020.mp4";
  
      String output = "/storage/emulated/0/Videa/Audio/AUDIO_20160330_142501.wav";
  
      String[] command = {
  
              "-y",
  
              "-i",
  
              input,
  
              "-vn",
  
              "-f",
  
              "wav",
  
              output
  
      };
  
      FFmpeg ffmpeg = FFmpeg.getInstance(getApplicationContext());
  
      try {
  
          ffmpeg.execute(command, new ExecuteBinaryResponseHandler() {
  
  
  
              @Override
  
              public void onSuccess(String message) {
  
                  super.onSuccess(message);
  
                  System.out.println("Success " + message);
  
              }
  
  
  
              @Override
  
              public void onFailure(String message) {
  
                  super.onFailure(message);
  
                  System.out.println("Failure " + message);
  
              }
  
          });
  
      } catch (Exception e) {
  
          e.printStackTrace();
  
      }

  And here is Failed command :

      ArrayList<string> cmd = new ArrayList<string>();
  
      cmd.add("-y");
  
      cmd.add("-i");
  
      cmd.add(input);
  
      cmd.add("-vn");
  
      cmd.add("-f");
  
      cmd.add("wav");
  
      cmd.add(output);
  
      String[] result = new String[cmd.size()];
  
      return cmd.toArray(result);
