I need to play vídeo files with Gem on Nobara linux which is Fedora based but when compiling Gem I can only get film-support to use QuickTime.

Does anyone know a way to install gmerin on Fedora?

or

What kind of video codecs work well with quicktime4linux? It complains about a bad magic number no matter what kind of file I try to open.

Thanks,
