/** @mainpage Calyp Project

Description
----------------------------------------------------------------

Calyp is an open-source video player with the following features:
- Support for libavformat and libavcodec;
- Support for wide range of raw video formats;
- Support up to 16 bits per pixel
- Support for OpenCV image/video processing library
- Advanced frame zoom with easy to use pan function
- Synchronized zoom across several videos (perfect for comparison operations)
- Useful information in status bar, *e.g.*, pixel information
    Useful sidebars with frame information, *e.g.*, frame histogram
- Constant growing libs for stream and frame processing (CalypStream and CalypFrame)
- Advanced API for frame/video processing algorithms
- Frame level quality measurement API based on the CalypFrame class
- Powefull command-line tool for quality and frame processing algorithms (uses the referred APIs)

Builds
----------------------------------------------------------------
Download update build for windows and linux from our <a href="https://sourceforge.net/projects/playuver/">SourceForge project page</a>


Build/Install using cmake
----------------------------------------------------------------

1. The following are required for compilation:
  - an ordinary C++ development environment (g++, make, C++ libraries and headers, ...)
  - cmake
  - a Qt development environment (libraries, headers, qmake, ...): only QtCore, QtGui and QtWidgets are required, at least in version 4

2. Optional Dependencies:
  - QtDBus
  - OpenCv
  - FFmpeg

3. Run the following commands: (this will create an executable named calyp)
```
mkdir build
cd build
cmake -DUSE_QT4=OFF -DUSE_FFMPEG=ON -DUSE_OPENCV=ON ..  (for FFmpeg and OpenCV support)
make
make install
```
