Use two DjiCodecManager at the same time.

[hvilinka]

Hi.

My drone matrice 210. DJI Android SDK 4.7.1 Device CrystalSky CS785, Android 5.1.1

I shuld display video stream from two camers at the same time, like a DJI Pilot. My solutions: I create two diferance DjiCodecManager, and use it in diferent VideoFeeder callbaks.

DJICodecManager primaryDJICodecManager  = new DJICodecManager(Activity,
        pramirySurfaceTexture,
        pramirySurfaceTextureTextureWidth,
        pramirySurfaceTextureTextureHeight);

DJICodecManager secondaryDJICodecManager  = new DJICodecManager(Activity,
        secondarySurfaceTexture,
        secondarySurfaceTextureTextureWidth,
        secondarySurfaceTextureTextureHeight);

pramirySurfaceTexture.setOnFrameAvailableListener(new SurfaceTexture.OnFrameAvailableListener() {
    @Override
    public void onFrameAvailable(SurfaceTexture surfaceTexture) {
        surfaceTexture.updateTexImage();
    }
});

secondarySurfaceTexture.setOnFrameAvailableListener(new SurfaceTexture.OnFrameAvailableListener() {
    @Override
    public void onFrameAvailable(SurfaceTexture surfaceTexture) {
        surfaceTexture.updateTexImage();
    }
});

VideoFeeder.VideoFeed videoFeed = VideoFeeder.getInstance().getPrimaryVideoFeed();
VideoFeeder.VideoFeed secondaryVideoFeed = VideoFeeder.getInstance().getSecondaryVideoFeed();

secondaryVideoFeed.setCallback(new VideoFeeder.VideoDataCallback() {
    @Override
    public void onReceive(byte[] videoBuffer, int size) {
        if (DjiManagers.mSecondaryCodecManager != null) {
            DjiManagers.mSecondaryCodecManager.sendDataToDecoder(videoBuffer, size);
        }
    }
});

videoFeed.setCallback(new VideoFeeder.VideoDataCallback() {
    @Override
    public void onReceive(byte[] videoBuffer, int size) {
        if (DjiManagers.mCodecManager != null) {
            DjiManagers.mCodecManager.sendDataToDecoder(videoBuffer, size);
        }
    }
});

But the pramirySurfaceTexture callback does not work. And on the second texture, an image from different cameras (color and grayscale (I use a thermal imaging camera)) appears alternately, but most often the texture is green.

Is it possible to create and use two DJICodecManager? And if not, how can I show the video stream simultaneously?
