How to stream live video from DJI Professional 3 camera ?
5 juin 2017, par raullalvesI have to get the live stream video from DJI Phantom 3 camera in my C++ application, in order to do a Computer Vision processing in OpenCV.
First I tried sending the H264 raw data through an UDP socket, inside this callback :
mReceivedVideoDataCallBack = new CameraReceivedVideoDataCallback() {
@Override
public void onResult(byte[] videoBuffer, int size) {
//Here, I call a method from a class I created, that sends the buffer through UDP
if (gravar_trigger) controleVideo.enviarFrame(videoBuffer, size);
if (mCodecManager != null) mCodecManager.sendDataToDecoder(videoBuffer, size);
}
};That communication above works well. However, I haven’t been able to decode that UDP H264 data in my C++ desktop application. I have tested with FFmpeg lib, but couldn’t get to alocate an
AVPacket
with my UDP data, in order to decode usingavcodec_send_packet
andavcodec_receive_frame
. I also had problems withAVCodecContext
, since my UDP communication wasn’t a stream like RTSP, where it could get information about its source. Therefore, I had to change how I was trying to solve the problem.Then, I found libstreaming, in which can be associate to stream the android video camera to a Wowza Server, creating something like a RTSP stream connection, where the data could be obtained in my final C++ application easily using OpenCV
videoCapture
. However, libstreaming uses its ownsurfaceView
. In other words, I would have to link the libstreamingsurfaceView
with the DJI Drone’svideoSurface
. I’m really new to Android, so don’t have any clue of how to do that.To sum up, is that the correct approach ? Someone has a better idea ? Thanks in advance
