ABOUT

GLMixer performs in real time the graphical blending of several movie clips. You would typically load a set of video samples by drag'n drop, and decide on the fly how much they should be visible, arrange the images in the screen, and which effects you apply to them.

The principle of interaction is to drop video files into a workspace, and to move them in a circular area to change their opacity ; if you selects two videos, moving them together makes a fading transition, and this principle is generalized to any number of videos. Direct interaction with the video icons allows you to be fast and reactive, and to move and deform videos on screen.

The output of your operations is shown in the main rendering window, which should for example be displayed full-screen on an external monitor or a projector, or can be saved as a video file.

DEPENDENCIES

To compile GLMixer you need; subversion cmake Qt Version 4 (not Qt 5) Libav (or ffmpeg) OpenCV (optionnal)

COMPILATION GUIDELINES

1. Install the dependencies

2. Checkout GLMixer source files from https://sourceforge.net/p/glmixer/Source/HEAD/tree/.

   svn checkout svn://svn.code.sf.net/p/glmixer/Source/trunk glmixer-Source

   or download source from

   https://sourceforge.net/projects/glmixer/files/Linux/

3. Create a folder for building (e.g. glmixer-Build)

4. Run CMake GUI and select the GLMixer top directory as location of the source. Do configure (choose Ninja) Make sure there is no error and set 'CMAKE_BUILD_TYPE' to 'Release' Do generate with CMake.

5. Compile : cd to the build folder, and run 'ninja' in a terminal to build the program (or use an IDE).

UNIX COMPILATION

 Open a terminal

 Go to the building directory
    $ cd glmixer-Build

 Run cmake command line to choose ninja generator.
    $ cmake -G Ninja ../glmixer-Source

 To be more specific, you might want to build a Release, ignore development warnings
 and use the optional features of OpenCV (web cam support) and FreeFrame (plugins):
    $ cmake -DCMAKE_BUILD_TYPE=Release -Wno-dev -DUSE_OPENCV=True -DUSE_UNDO=False -G Ninja ../

 If all goes well, it ends with :

    -- Configuring done
    -- Generating done
    -- Build files have been written to: XXX YOUR SOURCE PATH XXX

Compile with ninja :
    $ ninja

 It should end with a message like (ignore warnings):

    [128/128] Linking CXX executable src/glmixer

 You can run the program directly :
    $ ./src/glmixer

LINUX COMPILATION

Install programs and libraries (Ubuntu)

    $ sudo apt-get install subversion cmake-qt-gui ninja-build libqt4-opengl-dev libglew-dev libavformat-dev libhighgui-dev libavfilter-dev libv4l-dev xsltproc

(This installs all necessary packages such as xsltproc, libqtcore4, libqtgui4, libqt4-xml, libqt4-opengl, qt4-qmake, libqt4-dev, libqt4-opengl-dev, libavcodec-dev, libswscale-dev, libavformat-dev, libavutil-dev, libavfilter-dev, libglew-dev, libvorbis-dev, libx264-dev, libxvidcore-dev, libv4l-dev, libcv-dev, libcvaux-dev, libhighgui-dev, libv4l-dev).

You can now compile like under Unix (see above)

To install it in your system, run cmake (as above but) with the following options :

    $ cmake -D CMAKE_BUILD_TYPE=RelWithDebInfo -D USE_OPENCV=True -D USE_FREEFRAMEGL=1.6 -D CMAKE_INSTALL_PREFIX=/usr -G Ninja ../glmixer-Source/

After compiling the program (see above), build the debian package :

    $ cpack

It hopefully ends with :

    CPack: - package: /home/[YOUR SOURCE PATH]/GLMixer_[version].deb generated.

And you can now install it (use the filename generated above):

    $ sudo apt-get install /home/[YOUR SOURCE PATH]/GLMixer_[version].deb

OSX COMPILATION

Install home-brew

Follow instructions from http://brew.sh/

Install programs and libraries (run the following in a terminal)

    brew install subversion
    brew install ninja
    brew install cmake
    brew install ffmpeg
    brew install qt4
    brew install glew
    brew install homebrew/science/opencv

You can now compile like under Unix (see above)

WINDOWS COMPILATION

Install msys2

Follow instructions from https://msys2.github.io/

Install programs and x86_64 libraries (run the following in a terminal)

    pacman -S subversion
    pacman -S mingw-w64-x86_64-gcc
    pacman -S mingw-w64-x86_64-ninja
    pacman -S mingw-w64-x86_64-cmake
    pacman -S mingw-w64-x86_64-glew
    pacman -S mingw-w64-x86_64-qt4
    pacman -S mingw-w64-x86_64-opencv
    pacman -S mingw-w64-x86_64-ffmpeg

You can now compile like under Unix (see above)
