Example #1

public void encodeNativeFrame(Picture pic) throws IOException {
    if (toEncode == null) {
        toEncode = Picture.create(pic.getWidth() , pic.getHeight() , encoder.getSupportedColorSpaces()[0]);
    }

    // Perform conversion
    transform.transform(pic, toEncode);

    // Encode image into H.264 frame, the result is stored in '_out' buffer
    _out.clear();
    ByteBuffer result = encoder.encodeFrame(toEncode, _out);

    // Based on the frame above form correct MP4 packet
    spsList.clear();
    ppsList.clear();
    H264Utils.wipePS(result, spsList, ppsList);
    H264Utils.encodeMOVPacket(result);

    // Add packet to video track
    outTrack.addFrame(new MP4Packet(result, frameNo, timeScale, 1, frameNo, true, null, frameNo, 0));

    frameNo++;
