• FFmpeg problems on Android

  7 février 2015, par Scott

  Having realised that MediaPlayer will not do what I need in my application I decided to see if I could make FFmpegMediaPlayer work. I need to be able to seek to a specified point in milliseconds and Android MediaPlayer only seeks to the next key frame after the given time in milliseconds.

  I have written a small test app and added the pre built libraries from here :

  FFmpegMediaPlayer

  The code I am using to test is below, basically the same code from the sample at the link above. The issue I have is when I try to play the video file I just get an endless stream of logcat output until I kill the application :

  import java.io.IOException;    
  
  import wseemann.media.FFmpegMediaPlayer;
  
  import android.app.Activity;
  
  import android.graphics.PixelFormat;
  
  import android.media.MediaPlayer;
  
  import android.os.Bundle;
  
  import android.os.Environment;
  
  import android.util.Log;
  
  import android.view.SurfaceHolder;
  
  import android.view.SurfaceView;
  
  import android.view.View;
  
  import android.view.View.OnClickListener;
  
  import android.widget.Button;
  
  
  
  public class MainActivity extends Activity {
  
  
  
      Button btnPlay;
  
      public String TAG = "PlayerTest";
  
      public static String path = Environment.getExternalStorageDirectory().toString();
  
      public static String fileName = "/TestVideos/Five minute sync test.mp4";
  
      private SurfaceView mPreview;
  
      private SurfaceHolder holder;
  
  
  
      //private MediaPlayer mp;
  
      private FFmpegMediaPlayer mp;
  
  
  
      @Override
  
      protected void onCreate(Bundle savedInstanceState) {
  
          super.onCreate(savedInstanceState);
  
          setContentView(R.layout.activity_main);   
  
          btnPlay     = (Button)      findViewById(R.id.play);
  
          mPreview    = (SurfaceView) findViewById(R.id.surface);
  
          btnPlay.setOnClickListener(new OnClickListener(){
  
              @Override
  
              public void onClick(View v) {
  
                  playVideo();
  
              }
  
          });
  
          getWindow().setFormat(PixelFormat.TRANSPARENT);
  
          holder = mPreview.getHolder();
  
          holder.setFixedSize(400, 300);          
  
      }
  
  
  
      public void playVideo(){        
  
          mp = new FFmpegMediaPlayer();
  
          mp.setDisplay(mPreview.getHolder());        
  
          mp.setOnPreparedListener(new FFmpegMediaPlayer.OnPreparedListener() {
  
              @Override
  
              public void onPrepared(FFmpegMediaPlayer mp) {
  
                  mp.start();         
  
              }
  
          });
  
          mp.setOnErrorListener(new FFmpegMediaPlayer.OnErrorListener() {
  
              @Override
  
              public boolean onError(FFmpegMediaPlayer mp, int what, int extra) {
  
                  mp.release();
  
                  return false;
  
              }
  
          });
  
  
  
          try {
  
              mp.setDataSource(path+fileName);
  
              mp.prepareAsync();
  
          } catch (IllegalArgumentException e) {
  
              e.printStackTrace();
  
          } catch (SecurityException e) {
  
              e.printStackTrace();
  
          } catch (IllegalStateException e) {
  
              e.printStackTrace();
  
          } catch (IOException e) {
  
              e.printStackTrace();
  
          }
  
      }
  
  }

  Logcat output :

  TAG Fill buffer: 0 -> 30104

  If I change FFmpegMediaPlayer to MediaPlayer it runs fine. Is there something obvious that I am missing ?

• RTMP stream in Android using Vitamio with librtmp

  8 septembre 2015, par user3774795

  I need to play some rtmp video in android app. I found solution here. But when my video played more than 1 minutes, I got errors and video stopped.

  Code

  private String path;
  
  private int streamId;
  
  @Bind(R.id.streamVideoView) VideoView mVideoView;
  
  
  
  @Override
  
  protected void onCreate(Bundle savedInstanceState) {
  
      super.onCreate(savedInstanceState); 
  
      setContentView(R.layout.activity_view_stream);
  
      ButterKnife.bind(this);
  
      setupVideoView();        
  
  }
  
  
  
  private void setupVideoView() {
  
      path = getIntent().getStringExtra("streamURL");
  
      streamId = getIntent().getIntExtra("streamId", 0);
  
      if (!io.vov.vitamio.LibsChecker.checkVitamioLibs(this))
  
          return; 
  
      mVideoView.setVideoPath(path + " live=1");
  
      mVideoView.setBufferSize(2048);
  
      mVideoView.start();        
  
  }
