FFmpeg 6.1.x

When running the Windows Desktop or Runtime setup installers, the FFMpegInstaller should automatically start and download and install FFmpeg, so no extra steps for installing FFmpeg should be needed.
 

Starting from version R1 2024, Composer requires FFmpeg version 6.1. This applies to all Composer versions and Windows and Linux platforms. 

The Composer setup software includes a separate tool for downloading and installing FFMpeg. The FFmpeg installer (FFmpegInstaller.exe) is launched automatically and will download and install FFmpeg. 

Select Download and Install to start the download and installation procedure.

The installer will download FFmpeg from www.gyan.dev/ffmpeg/builds/packages/ffmpeg-6.1.1-full_build-shared.7z and copy the FFmpeg files to C:\Program Files\FFmpeg\6. 

(The search path used by Composer can be adjusted using the registry key COMPOSER_FFMPEG6 found at Computer\HKEY_LOCAL_MACHINE\SOFTWARE\RealSprint AB).

FFMpegInstaller.exe

If you need to re-install FFMpeg 6.x, or if you wanna pre-install FFmpeg before running the application setup software, the installer can be found in the Composer application folder (typically C:\Program Files\RealSprint AB\Vindral Composer) and is called FFMpegInstaller.exe. You can run the installer manually. 

The application will quit automatically if the installer detects a valid FFmpeg installation. 

Optional command line parameters:

- FORCEINSTALL
The FORCEINSTALL option will force the installer to continue even if a previous FFmpeg version was found.

- SILENT
The SILENT option will run the installer without any required user interaction.

After the installer has been run, the FFmpeg folder content should look like this:

If you are missing a valid FFmpeg folder (above), the Desktop version will show an error message during startup:

The Runtime version will log errors:

If any of the errors above occur, please download and install FFmpeg using the FFMpegInstaller.exe.
