# limmto # MediaTool
limmto (Light Multi-Media Tool) is a free, low-dependency C++ library for working with digital media.
This is a collection of tools and apps for working with various media (Web, Desktop Publishing, Video/Audio) on different platforms (Linux, Windows).
It tries to have low dependencies and lots of things are built from scratch.
This is a personal/hobby project - things will break/change a lot.
# Build Dependencies
## Linux
### Minimal
```bash
sudo apt-get install build-essential cmake
```
### Optional
#### Audio
```bash
sudo apt-get install libasound2-dev
```
#### Image Formats
```bash
sudo apt-get install libpng-dev
```
# Build from Source
## Linux
```bash ```bash
mkdir build mkdir build
