Mavic Mini YUV data not received

[jeryini]

Hello!

I'm using Mobile SDK Android library version 4.13 which has official support for Mavic Mini. I'm getting all telemetry data and also video feed. But due to requirements to do some processing on the video feed, I'm setting YUV data callback:

codecManager.enabledYuvData(true);
codecManager.setYuvDataCallback(new DJICodecManager.YuvDataCallback() {
    @Override
    public void onYuvDataReceived(MediaFormat mediaFormat, ByteBuffer yuvFrame, int dataSize, int width, int height) 

Unfortunately I'm not receiving anything inside onYuvDataReceived method. I should say that I also own Mavic 2 Zoom and it works flawlessly. Is maybe YUVDataCallback not supported for Mavic Mini?

Dear jeryini,

Thank you for contacting DJI. I tested it with 4.13.1 and YUVfeature works well. Can you please upgrade to the latest 4.13.1 and test it again?

Thanks,

Hello! I just tried with 4.13.1 and there are still no yuvframes being received. But I'm seeing this in the console, I don't think I saw this with Mavic 2 Zoom:

Dear jeryini,

Thank you for contacting DJI. The log seems something related to the GAODE map and missing the KEY. Please try to search if you are using the GAODE map.

Can you please show me some debug screenshots or videos like the following?

showToast("enabledYuvData");

codecManager.enabledYuvData(true);codecManager.setYuvDataCallback(new DJICodecManager.YuvDataCallback() { @Override public void onYuvDataReceived(MediaFormat mediaFormat, ByteBuffer yuvFrame, int dataSize, int width, int height) {

showToast( "onYuvDataReceived called");

}

Thanks,

Hello @dji-dev !

Even better, I've created an example gist that uses Mobile-UXSDK-Beta-Android as a base. I'm using latest master branch from that project. Basically I added a part fpvWidget.setCodecManagerCallback to set new codec manager and enable YUV data. Here is the log output when running the app and that main default layout activity and being connected to the drone. If you search for string you will be able to find entry for both Codec manager changed and YUV data enabled, but nothing for New YUV data received. Hope this will help you figure out the problem.

Hello @dji-dev !

Did you maybe get back from support regarding my above example and log output?
