Compilation

On Linux, the following packages are required (tested on Debian Jessie):
libavutil-dev, libavfilter-dev, libavcodec-dev

On Windows, all dependencies should be provided in the source code. Note that ffmpeg and its libraries must be present in the build directory (or the PATH environment variable) in order for the application to run after compiling.

A deployment script for Qt components is also provided. It will compile translations and copy dependencies to a specified build directory on Windows for MSVC and MinGW compilers. wget and unzip (e.g. GnuWin32 ports) are required to deploy ffmpeg libraries automatically. Edit the variables in release.bat based on your Qt installation, then run it after compiling in release mode.

Dependencies

On Linux, the ffmpeg and qt5 packages are required to run Webbum, and the fontconfig package is required for proper subtitle support.

On Windows, the Microsoft Visual C++ 2013 Redistributable package is required to run Webbum. Release builds include the appropriate ffmpeg binaries from Zeranoe.

For custom builds of ffmpeg, the following options are recommended: --disable-static, --enable-shared, --enable-fontconfig, --enable-libass, --enable-libopus, --enable-libvorbis, --enable-libvpx, --enable-libx265, --enable-libaom. These options should cover most typical input content.

All other libraries and dependencies should be provided.

You can’t perform that action at this time.
