Does this work with the N1 Video Encoder

Hi,

I am unable to get this working with the N1 Video Encoder. Has anyone got that working or is that just for the Go App?

Cheers, Andrew

Hi! Currently, the FPVDemo doesn't support N1 Video Encoder. The video data could be obtained by setting setDJIOnReceivedVideoCallback in LBAirlink of Airlink for M100 with N1 decoder. We may update the FPVDemo to support it in the future update.

Thanks :) Any chance of this demo being published to the store so people can have a look at the compiled output?

Since it's a simple demo without good UI design and friendly user interaction, we won't publish the demo application to store, you can easily download the sample code, fill in the App Key and build and run on your Android device. Then connect the application to DJI Product to view the live video. It's that easy.

I haven't dealt with Android or the DJI SDK before. I believe my changes are right. Only if you have spare time can you please confirm them. If so I can submit a PR :) https://github.com/DJI-Mobile-SDK/Android-FPVDemo/compare/master...andymac4182:lightbridge?expand=1

Hi, I suggest to modify the initPreviewer() method as shown below:

private void initPreviewer() {

        DJIBaseProduct product = FPVDemoApplication.getProductInstance();

        if (product == null || !product.isConnected()) {
            showToast(getString(R.string.disconnected));
        } else {
            if (null != mVideoSurface) {
                mVideoSurface.setSurfaceTextureListener(this);
            }
            if (!product.getModel().equals(Model.UnknownAircraft)) {
                DJICamera camera = product.getCamera();
                if (camera != null){
                    // Set the callback
                    camera.setDJICameraReceivedVideoDataCallback(mReceivedVideoDataCallBack);
                }else if(product.getModel().equals(Model.Matrice_100)){ //Add the product checking here
                    product.getAirLink().getLBAirLink().setDJIOnReceivedVideoCallback(mReceivedVideoDataCallBackLightbridge);
                }
            }
        }
    }

For others are fine. Hope this help.

Ahh. We are using the N1 on an Inspire so wasn't sure if that would work. I will have a play around to see what happens.

Yes, N1 Video Encoder is only used on M100, for more info, please check the DJI Website: https://store.dji.com/product/n1-video-encoder

Since this issue has been solved, I will close it then.
