RtspLibrary

Android library based on FFMpeg for playing given RTSP endpoint.

Pipeline

1. Open RTSP Endpoint
2. Find Video Stream
3. Read Frame
4. Convert to RGB
5. Invoke Callback
6. Java Interface

Setup

1. In root build.gradle:

allprojects {
  repositories {
    ...
    maven { url 'https://jitpack.io' }
  }
}

2. In target module build.gradle

dependencies {
  compile 'com.github.potterhsu:RtspLibrary:v1.0'
}

Usage

1. Initialize

ImageView ivPreview = (ImageView) findViewById(R.id.ivPreview);
RtspClient rtspClient = new RtspClient(new NativeCallback() {
    @Override
    public void onFrame(final byte[] frame, final int nChannel, final int width, final int height) {
        ivPreview.post(new Runnable() {
            @Override
            public void run() {
                int area = width * height;
                int pixels[] = new int[area];
                for (int i = 0; i < area; i++) {
                    int r = frame[3 * i];
                    int g = frame[3 * i + 1];
                    int b = frame[3 * i + 2];
                    if (r < 0) r += 255;
                    if (g < 0) g += 255;
                    if (b < 0) b += 255;
                    pixels[i] = Color.rgb(r, g, b);
                }
                Bitmap bmp = Bitmap.createBitmap(pixels, width, height, Bitmap.Config.ARGB_8888);
                ivPreview.setImageBitmap(bmp);
            }
        });
    }
});

2. Play

new Thread(new Runnable() {
    @Override
    public void run() {
        rtspClient.play("rtsp://endpoint/to/rtsp");
    }
}).start();

3. Stop and release

rtspClient.stop();
rtspClient.dispose();
