• Android watermark : Fatal signal 4 (SIGILL), code 2, fault addr 0xe2166842 in tid 13693 (atermarkvideo_2

  27 avril 2016, par Sakibmohammad Syed

  I am using ffmpeg library for watermark on video and below is my code but when I run program the it show error like Fatal signal 4 (SIGILL), code 2, fault addr 0xe2166842
  here is my code.

      public class MainActivity extends Activity {
  
      private String strAudioFolderPath;
  
      @Override
  
      protected void onCreate(Bundle savedInstanceState) {
  
          super.onCreate(savedInstanceState);
  
          setContentView(R.layout.activity_main);
  
  
  
          strAudioFolderPath = "/sdcard/Download";
  
          String s = "ffmpeg -i /sdcard/Download/testing.mp4 -i /sdcard/test.png -filter_complex 'overlay=10:main_h-overlay_h-10' /sdcard/Download/out.mp4";
  
  
  
          GeneralUtils.deleteFileUtil(strAudioFolderPath + "vk.log");
  
  
  
          PowerManager powerManager = (PowerManager) this.getSystemService(Activity.POWER_SERVICE);
  
          PowerManager.WakeLock wakeLock = powerManager.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, "VK_LOCK");
  
          wakeLock.acquire();
  
          LoadJNI vk = new LoadJNI();
  
          try {
  
              try {
  
                  vk.run(GeneralUtils.utilConvertToComplex(s), strAudioFolderPath, MainActivity.this);
  
                  Log.e("Checking water marker", ">>>>>>>>>>>>>>>");
  
  
  
              } catch (Throwable e) {
  
              } finally {
  
                  if (wakeLock.isHeld())
  
                      wakeLock.release();
  
                  else {
  
                  }
  
              }
  
          } catch (Exception e)
  
          {
  
              e.printStackTrace();
  
          }
  
      }

  Actually I want to add watermark on video file using ffmpeg library but it show error as I mention above so I am unable to watermak on video. I have also seach a lot to solve this issue but I did not find any proper solution of this problem.

• 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

• android:video watermark show error

  I want to watermark video and below is my code but when I try to run then it show error like Failed to validate license file, existing!.

      public class MainActivity extends AppCompatActivity {
  
      private String strAudioFolderPath;
  
      @Override
  
      protected void onCreate(Bundle savedInstanceState) {
  
          super.onCreate(savedInstanceState);

          // here my ffmpeg command to watermark video.
  
          String s = "ffmpeg -i /sdcard/Download/testing.mp4 -i /sdcard/temp1.jpg -filter_complex 'overlay=10:main_h-overlay_h-10' /sdcard/Download/out.mp4";
