  • Android FFmpeg Video Player

    11 mars 2013, par Dilip

    I want to play video using FFmpeg for this have used some code,But it open file but not drawing frames thowing Unhandled page fault exception.

    Java Code :

    public class MainActivity extends Activity {
       private static native void openFile();

       private static native void drawFrame(Bitmap bitmap);

       private static native void drawFrameAt(Bitmap bitmap, int secs);

       private Bitmap mBitmap;
       private int mSecs = 0;

       static {
           System.loadLibrary("ffmpegutils");
       }

       /** Called when the activity is first created. */
       @Override
       public void onCreate(Bundle savedInstanceState) {
           super.onCreate(savedInstanceState);
           // setContentView(new VideoView(this));
           setContentView(R.layout.main);

           mBitmap = Bitmap.createBitmap(320, 240, Bitmap.Config.ARGB_8888);
           openFile();

           Button btn = (Button) findViewById(R.id.frame_adv);
           btn.setOnClickListener(new OnClickListener() {
               public void onClick(View v) {
                   try {
                       drawFrame(mBitmap);
                       ImageView i = (ImageView) findViewById(R.id.frame);
                       i.setImageBitmap(mBitmap);
                   } catch (Exception e) {

  • Encoder/Decoder PCM to AMR Android

    2 mars 2013, par Syred

    I've been looking for a while now for any java library that allows me to encode and decode a PCM-AMR audio stream that is sent through a TCP socket connection. Without having to use Android's JNI.

    Is there anything that can help me ?

    In the worst case scenario. How can I do it using any C++ library with JNI ? (any reference of how to use ffmpeg with JNI will be appreciated)

    Hope you can help me.
