Bonjour,
une histoire à se casser la tête;
Tout d'abord, je remercie ceux qui vont m'aider.
J'ai donc suivis ces deux tutoriels :
https://fedoraproject.org/wiki/OpenH264 et ainsi que celui ci :
https://doc.fedora-fr.org/wiki/Carte_graphique_ATI_-_AMD_Radeon_:_installation_des_pilotes_libres
Le problème : vidéo qui s'affiche en une image; et le son tourne toujours, son non synchronisé sur la vidéo, ou encore, vidéo qui dure le temps d'un gif; soit quelques secondes, puis seulement du son. Fenêtre du lecteur vidéo petite ou grande, la vidéo ne s'affiche pas correctement.
Si vous voulez des retours de commande ? merci à vous !

note : les petites vidéos en basse résolution genre 480P ça marche, surtout c'est du dessin animé, mais les vidéos en HD ça marche pas. je viens de désintaller VLC.
