This project started from https://github.com/TobiasBales/PlayuavOSD.git

Supported platforms:

• Raspberry Pi 0-3 -- native mode (use VideoCore IV API)
• Linux with X11 -- use gstreamer overlay

Supported autopilots:

• PX4 -- full support
• Ardupilot -- should work, but not tested
• any mavlink-based -- should work with small fixes

Building:

1. Build for Linux X11 (native build):

• apt-get install libcairo2-dev gstreamer1.0-tools libgstreamer1.0-dev gstreamer1.0-plugins-base gstreamer1.0-plugins-bad gstreamer1.0-plugins-good gstreamer1.0-plugins-ugly libgstreamer-plugins-base1.0-dev
• make osd

2. Build for Raspberry PI (cross-build):

• make build_rpi (you need linux machine with docker installed)

3. Build for Raspberry PI (native build):

• make osd mode=rpi

Running:

Default mavlink port which OSD listen is 14550.

1. RPI: ./osd
2. Linux X11:
   • Run test video stream (OSD will not work without video stream)

      gst-launch-1.0 videotestsrc pattern=black ! videoconvert ! \
      video/x-raw,format=NV12,framerate=30/1,width=1280,height=720,format=I420 ! \
      x264enc bitrate=4000 tune=zerolatency ! rtph264pay config-interval=1 ! \
      udpsink host=127.0.0.1 port=5600
   

   • Run OSD: ./osd
   • You should got screen like this:
