## cam2ip

Turn any webcam into an IP camera.

Example (in web browser):

    http://localhost:56000/html

or

    http://localhost:56000/mjpeg

You can also use apps like `ffplay` or `vlc`:

    ffplay -i http://localhost:56000/mjpeg

### Requirements

* On Linux/RPi native Go [V4L](https://github.com/korandiz/v4l) implementation is used to capture images.
* On Windows [Video for Windows (VfW)](https://en.wikipedia.org/wiki/Video_for_Windows) framework is used over win32 API.

### Build tags

* `opencv` - use `OpenCV` library to access camera ([gocv](https://github.com/hybridgroup/gocv))
* `libjpeg` - build with `libjpeg` ([go-libjpeg](https://github.com/pixiv/go-libjpeg)) instead of native `image/jpeg`
* `jpegli` - build with `jpegli` ([jpegli](https://github.com/gen2brain/jpegli)) instead of native `image/jpeg`

### Download

Download the latest binaries from the [releases](https://github.com/gen2brain/cam2ip/releases).

### Installation

    go install github.com/gen2brain/cam2ip/cmd/cam2ip@latest

This command will install `cam2ip` in `GOBIN`, you can point `GOBIN` to e.g. `/usr/local/bin` or `~/.local/bin`.

### Run in Docker container
