Hi, I am working on Ubuntu 19.04: I have set up a freelan in order to give control of the BlueROV2 to a distant PC (IP: 9.0.0.13). I achieve to give control with a Netcat command launched on companion PC (IP: 9.0.0.12): ``` mkfifo backpipe nc -ulp 14550 0backpipe ``` It works. But, when I do the same for Video stream: ``` mkfifo campipe nc -ulp 5600 0campipe ``` I get the following error in QGC on remote PC: “VideoReceiverLog : Failed because video sink is not set” Any idea on how to fix this ? Thanks. ---

Hi, Answering my own post… It seems to be impossible to send Video stream using Netcat, like I do with MAVLink commands. But you can send the stream using an RTSP server. To do this: 1 - On companion PC Install Nginx and launch service (maybe useless cause you can get the stream directly from Pi, anyway, continue 🙂 ) Create a file called “vlc.sdp” in “/var/www/html” default folder with content: ``` c=IN IP4 127.0.0.1 m=video 5600 RTP/AVP 96 a=rtpmap:96 H264/90000 ``` Open VLC software Broadcast a Network stream (Media \> Broadcast \> Network) and type location: [http://127.0.0.1/vlc.sdp](http://127.0.0.1/vlc.sdp) Click “Broadcast” and “Next” button Choose destination “RSTP” and click “Add” button By default port is 8554. Keep it like this. Type “/stream” to complete the URI and click “Next” Click on the wrench button and “Codec Video” tab Check “Keep original video track” Save and click next You are now streaming camera. 2 - In QGC client Go to “General” settings to receive the stream In Video paragraph, select RTSP source and type : rstp://9.0.0.12:8554/stream Go back to main screen Here you are, you now receive the stream from your BlueROV2. ---

To get low latency, use on companion PC: ``` gst-launch-1.0 udpsrc port=5600 ! tee name='video' ! queue ! udpsink host=9.0.0.14 port=5600 video. ! application/x-rtp,encoding-name=H264,payload=96 ! rtph264depay ! h264parse ! avdec_h264 ```
