# PMVR

The Raspberry **P**i **M**otion **V**ideo **R**ecorder 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.

# Setup

  * 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.

  * Raspivid

    * On Arch Linux this is provided as part of `raspberrypi-firmware` but is not listed in the path. It must be in the path.

  * FFmpeg (or avconv symlinked as ffmpeg, if you must)

  * A named pipe for motion vectors: `mkfifo motion_vectors.fifo`

# Installation

```go

go get -v github.com/bemasher/pmvr

go install -v github.com/bemasher/pmvr

```

# Running

```bash

pmvr

```

# Resource Usage

Except for determining magnitude of motion over each frame, we're just shuffling data around. PMVR is very light on resources:

# Improvements and Feature Requests

Have any improvements or feature requests? Submit an issue and we'll discuss feasibility.

# ToDo

- [ ] Add command line flags for:

  - [ ] Motion detection thresholds.

  - [ ] Raspivid command line options.

  - [ ] FFmpeg command line options.
