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);

How I can use Runtime.getRuntime.exec with ffmpeg library in Android ?

24 février 2015, par beni

I’m trying to establish the correct rotation in my recorded video because in some devices the setOrientationHint method doesn’ work becuase in some video players may choose to ignore the compostion matrix in a video during playback, Android Documentation.

So, I’ve decided to use the ffmpeg library. I’m develop a test for the app. In Ubuntu, I download this library and execute the configure and make to obtain the ffmpeg executable, I copy this executable to the DCIM folder in the sdcard, the same for a video what I’ve recorded for my camera recorder app. So, in the DCIM folder, I have the ffmpeg executable and a video.

I created a test project and in the onCreate method, I’ve include :

try {



Process p= Runtime.getRuntime().exec("chmod 777 /mnt/sdcard/beni/ffmpeg");

p.waitFor();



p = Runtime.getRuntime().exec("/mnt/sdcard/beni/ffmpeg -i /mnt/sdcard/beni/f.mp4 -vf \"transpose=1\" -r 24 -sameq /mnt/sdcard/beni/f2.mp4");

p.waitFor();



BufferedReader in = new BufferedReader(new InputStreamReader(p.getInputStream()));  

String line = null;  

while ((line = in.readLine()) != null) {  

    System.out.println(line);  

}  









} catch (IOException e) {

    e.printStackTrace();

} catch (InterruptedException e) {

e.printStackTrace();

}

but I have the following warning :

Is this code right ? Or I’ve done something wrong.

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.
