# rpi-video-rs

This project implements `H264` video record on Raspberry Pi. It uses the

`rust-ffi` binding library

[rpi-mmal-rs](https://github.com/Pragmatic-Elixir-Meetup/rpi-mmal-rs).

## Usage

Add the following to your `Cargo.toml`:

```toml

[dependencies]

rpi-video-rs = "0.0.3"

```

You could checkout the user code in folder `examples/`.

And run the `simple` one as below.

```

cargo run --example simple

```

## Development

Since this project requires the real camera to record H264 videos, you needs a

RPI to run or test. But you could also uses a cross-compiling environment for

compiling and developing. We offer a Dockerfile (in folder `tools/docker/`)

which is a separate cross-compiling environment.

For developing on either a RPI device or a Docker container, you should install

the standard Rust development environment, and then adds Rust targets as below.

```

rustup target add arm-unknown-linux-gnueabihf

rustup target add armv7-unknown-linux-gnueabihf

```

### Installing Camera Device on RPI

1. Adds text `bcm2835-v4l2` to the bottom of file `/etc/modules`.

```

sudo echo bcm2835-v4l2 >> /etc/modules

```

2. Activates the camera in configuration.

```

sudo raspi-config

```

3. Follows the prompt to reboot Raspberry PI.

4. You could use the command `raspivid` to test recording a `H264` video and

check if the camera is installed properly.

```

raspivid -o test_video.h264

```

### C Version Code

1. Enters into the folder `tools/c_ver`, and runs `make` to compile the command

`rpi_video.out`.

```

pushd tools/c_ver

make

```

2. Runs the build command `rpi_video.out` to record a sample video.

```

./rpi_video.out

```

### Rust Simple Example

You could run the Rust simple example as below.

```

cargo run --example simple

```

## TODO

1. Integrates with a CI for testing successful compilation.
