J'essaie de convertir un fichier mov que j'ai obtenu en enregistrant ma présentation powerpoint dans un fichier vidéo. Cependant, seule une partie de la présentation est convertie et l'exécution de qt-start ne transforme pas le mp4 exporté en flux sur rtmp. Y a-t-il quelque chose qui me manque?conversion .mov en .mp4 en utilisant ffmpeg ne convertit pas la vidéo entière
Je joins la sortie que je reçois quand je suis en train de convertir le fichier en utilisant ffmpeg
