Video Streaming API for Android

[hellowill89]

We should work together to establish an Android API which makes it easier to get the video feed from the Tello. From what I can tell, the raw data comes in over port 11111, and then needs to be decoded from H.264. It is somewhat arduous for a regular developer to do this video decoding, so it would be amazing if there was a library out there that could support that functionality. The video feed unlocks a lot of cool behavior for the Tello. What are people's thoughts on it?

Hey,
I am trying to work on this. I am having issues to display the video on my android app. I have decided to use OpenCV to do decoding from H.264, but I still do not have success. Please see a glance of what I tried to do.

How to display video from a UDP socket using OpenCV in Android? (DjiTello)

I am trying to get the video that is streamed from the drone Dji Tello. It streams through a UDP socket on IP address 0.0.0.0 and on port 11111. I am trying to display the video on a surfaceview, ...

Hey @hellowill89, are you still interested in this topic. I may work on this along with you if you want to continue. Till date I have been able to decode only a frame of the video. But this was without any third party libraries (Using MediaCodec, and I feel that's a lot of progress from where I've started). I'm stuck at combining the slices into a frame. I have tried many ways, but none worked. I just need the information regarding how to know the end of a frame. I've seen something like this if(frame.length != 1460){//eof} in the Python SDK and tried implementing the same. But I've seen that my parser returns frames of size "8" and "13", in a regular pattern.
Can anyone help me with this?

Thanks
Harshith.
