VLC Troubleshooting - GoldenCheetah/GoldenCheetah GitHub Wiki
From v3.6 GoldenCheetah binaries include vlc for user's convenience, you can check the specific version in Help > About... > Version
.
If you are having issues in your system (see goldencheetah.log for error messages) or you want to use other vlc version, it is possible to extract the AppImage to a local filesystem running it with --appimage-extract command line option and remove the included vlc to use your system vlc.
For example in Ubuntu 22.04 you can do:
sudo apt update
sudo apt install vlc
./GoldenCheetah_v3.7_x64.AppImage --appimage-extract
cd squashfs-root
rm -r vlc libvlc*
./AppRun
