OperaThemeMaker automates the creation of archive files to be consumed by various iterations of Opera Browsers to customize still and animated themes. Basic video editing capabilities are also included to add better personalization namely:
- Vignette
- Box Blur
- Edge Detection
- Monochrome
In a terminal, enter the following commands.
git clone --recursive https://github.com/HawtStrokes/OperaThemeMaker.git
cd OperaThemeMaker/External/
git submodule update --recursive --init
Follow Installation guide at https://github.com/Raveler/ffmpeg-cpp
Use Cmake to generate the solution file. For ease of building, I suggest using cmake-gui. Open cmake-gui and point the source code to <complete absolute path to>\OperaThemeMaker\External\glfw and set the binaries location to <complete absolute path to>\OperaThemeMaker\External\glfw\build
Open the generated solution file in the build folder and build Debug|x64 and Release|x64 configurations.
Open the solution file in the OperaThemeMaker root directory, and build Release_Static and Debug_Static configurations of HawtLib.
In file explorer, go to the following directories and open the following batch file:
- In
OperaThemeMaker\External\HawtLib\HawtLib\ScriptsopenMakeIncludes.bat
Video editing is done via ffmpeg-cpp, which adds the desired video effects and converts the input video to WEBM format. The output video, along with the thumbnail and persona.ini are then archived and placed in Opera's theme folder.

Using Monochrome and Edge Detection simultaneously corrupts the video output.
