The Raspberry Pi Motion Video Recorder is a proof of concept daemon that makes use of the motion estimation vectors available from the RPi's hardware accelerated H.264 encoder to detect and save clips of motion.
- Requires the Go toolchain (>=go1.8)
- I've not checked this for standard library compatibility with anything prior to
go1.8. It may or may not work on versions prior to that.
- I've not checked this for standard library compatibility with anything prior to
- Raspivid
- On Arch Linux this is provided as part of
raspberrypi-firmwarebut is not listed in the path. It must be in the path.
- On Arch Linux this is provided as part of
- FFmpeg (or avconv symlinked as ffmpeg, if you must)
- A named pipe for motion vectors:
mkfifo motion_vectors.fifo
go get -v github.com/bemasher/pmvr
go install -v github.com/bemasher/pmvrpmvrExcept for determining magnitude of motion over each frame, we're just shuffling data around. PMVR is very light on resources:
Have any improvements or feature requests? Submit an issue and we'll discuss feasibility.
- Add command line flags for:
- Motion detection thresholds.
- Raspivid command line options.
- FFmpeg command line options.
