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

Supported platforms:

• Raspberry Pi 0-3 -- use hardware overlay mode (OpenVG)
• Radxa Zero 3W/3E -- use hardware overlay mode (libdrm)
• OrangePi 5 -- use hardware overlay mode (libdrm)
• Any other Linux with X11/Wayland and GPU -- use GStreamer OpenGL mixer

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 or Wayland) (native build):

• apt-get install gstreamer1.0-tools pkg-config 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 0-3 (OpenVG) (native build):

• make osd mode=rpi3

3. Build for Radxa or OrangePi (libdrm) (native build):

• apt-get install libdrm-dev pkg-config
• make osd mode=rockchip

Running:

Default mavlink port is UDP 14551. Default RTP video port is UDP 5600.

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