# vimix
__Live Video Mixing__
<img src=docs/vimix_screenshot.png width="800">
vimix performs graphical mixing and blending of several movie clips and
computer generated graphics, with image processing effects in real-time.
Its intuitive and hands-on user interface gives direct control on image opacity and
shape for producing live graphics during concerts and VJ-ing sessions.
The output image is typically projected full-screen on an external
monitor or a projector, and can be streamed live (SRT, Shmdata) or recorded (without audio).
vimix is the successor for GLMixer - https://sourceforge.net/projects/glmixer/
# License
GPL-3.0-or-later
See [LICENSE](https://github.com/brunoherbelin/vimix/blob/master/LICENSE)
# Install vimix
Check the [Quick Installation Guide](https://github.com/brunoherbelin/vimix/wiki/Quick-Installation-Guide)
### Linux
Download and install a released [flatpak package](https://flathub.org/apps/details/io.github.brunoherbelin.Vimix)
flatpak install --user vimix
NB: Build your flatpak package to get the latest beta version; instructions are [here](https://github.com/brunoherbelin/vimix/tree/master/flatpak).
[](https://snapcraft.io/vimix)
Download and install a released [snap package](https://snapcraft.io/vimix)
snap install vimix
Install the stable debian package (slower release frequency)
sudo apt install vimix
### Mac OSX
Download and open a release package from https://github.com/brunoherbelin/vimix/releases
NB: You'll need to accept the exception in OSX security preference.
# Build vimix
## Clone
git clone --recursive https://github.com/brunoherbelin/vimix.git
This will create the directory 'vimix', download the latest version of vimix code,
and (recursively) clone all the internal git dependencies.
## Compile
First time after git clone:
mkdir vimix-build
cd vimix-build
cmake -DCMAKE_BUILD_TYPE=Release ../vimix
cmake --build .
This will create the directory 'vimix-build', configure the program for build, and compile vimix.
If successful, the compilation will have produced the executable `vimix` in the `src` directory.
You can run vimix with `./src/vimix` :
...
[100%] Built target vimix
./src/vimix
## Update clone and re-compile
Run these commands from the `vimix-build` directory if you did 'Clone' and 'Compile' previously and only want to get the latest update and rebuild.
git -C ../vimix/ pull
cmake --build .
This will pull the latest commit from git and recompile.
## Try the Beta branch
Run this commands from the `vimix-build` directory before runing 'Update clone and re-compile above'
git -C ../vimix/ checkout beta
It should say;
branch 'beta' set up to track 'origin/beta'.
Switched to a new branch 'beta'
