• fatal singal 11 error on FFMPEG streaming for RTSP

  2 mars 2018, par Anuran Barman

  I have added rtsp streaming with FFMPEG in my app.What I am trying to do is add two fragments (each will load different rtsp streaming) into single activity.
  While the first fragment in first LinearLayout is working fine second one is giving error as mentioned in the question. What can be the possible reason for this ? I am loading the library in static block , can that be the reason ?

  My code for single fragment which is added twice in two different linear.
  layouts.

  My activity which is loading the two fragments :

  public class CamerasActivity extends BaseActivity {
  
  
  
      FragmentManager fragmentManager;
  
      FragmentTransaction fragmentTransaction;
  
  
  
      @Override
  
      protected void onCreate(Bundle savedInstanceState) {
  
          super.onCreate(savedInstanceState);
  
          setContentView(R.layout.activity_cameras);
  
  
  
          fragmentManager=getSupportFragmentManager();
  
          fragmentTransaction=fragmentManager.beginTransaction();
  
  
  
          StreamingActivity streamingFragment=new StreamingActivity();
  
          Bundle bundle=new Bundle();
  
          bundle.putString("url",getIntent().getStringExtra(Constants.IntentExtras.DATA));
  
          streamingFragment.setArguments(bundle);
  
  
  
          StreamingActivity streamingFragment2=new StreamingActivity();
  
          Bundle bundle2=new Bundle();
  
          bundle2.putString("url",getIntent().getStringExtra(Constants.IntentExtras.DATA));
  
          streamingFragment2.setArguments(bundle2);
  
  
  
          fragmentTransaction.replace(R.id.frame1,streamingFragment);
  
          fragmentTransaction.replace(R.id.frame2,streamingFragment2);
  
  
  
          fragmentTransaction.commit();
  
      }
  
  }

  layout for CamerasActivity.java

  <?xml version="1.0" encoding="utf-8"?>
  
  <linearlayout>
  
      <linearlayout></linearlayout>
  
      <linearlayout></linearlayout>
  
  </linearlayout>

  Why is the second fragment crashing ?
  As we mention in the JNI wrapper which Java class will be calling the native functions can there only one instance of that class in whole scope ? can that be the reason ?
