Mavlink Camera Manager

The Mavlink Camera Manager is an extensible cross-platform camera server.

It provides a RTSP service for sharing video stream and a MAVLink camera protocol compatible API to configure ground control stations (E.g: QGroundControl).

How to test it

Get video via player

You can get the video via VLC or any other media player that can receive video via rtsp

Guide:

1. Start mavlink-camera-manager via cargo run or calling the binary directly.
2. Open player and set the rtsp string that the command line provides
3. Done

Get video via Ground Control Stations

The video should automatically popup if you are using any modern GCS, like QGroundControl, that has support for MAVLink camera messages.

Guide:

1. Start mavlink-camera-manager via cargo run or calling the binary directly.
2. Start mavproxy or sim_vehicle with --out=udpbcast:0.0.0.0:14550
   • By default mavlink-camera-manager uses 14550 to perform the mavlink connection
3. Open your Ground Control Station
4. Done

Use your own pipeline

You can use your own pipeline via --pipeline-rtsp parameter, some examples:

• 'videotestsrc ! video/x-raw,width=640,height=480 ! videoconvert ! x264enc ! rtph264pay name=pay0'
• 'rtspsrc location="rtsp://wowzaec2demo.streamlock.net/vod/mp4:BigBuckBunny_115k.mov" latency=100 ! rtph264depay ! rtph264pay name=pay0'
• 'v4l2src device=/dev/video0 ! video/x-h264,width=1920,height=1080,type=video ! rtph264pay name=pay0'

Note that some GCS only supports video encoded with H264

How to build it

Remember to install:

• libgstreamer1.0-dev
• libgstreamer-plugins-base1.0-dev
• libgstrtspserver-1.0-dev

If the compilation is failing to find one of this packages, make sure that they are visible for pkg-config, may be necessary to set PKG_CONFIG_PATH environment variable.

Example:

• export PKG_CONFIG_PATH=/usr/local/Cellar/gst-plugins-base/1.16.2/lib/pkgconfig/

After having installed all dependencies, you'll be able to build via cargo after cloning.

• cargo build

If cargo is not available, install and configure rustup.
