Spécification du transcodage vidéo dans une définition de tâche Amazon ECS

Dans l'exemple suivant, la syntaxe utilisée pour la définition de tâche d'un conteneur Linux sur Amazon EC2 est fournie. Cette définition de tâche concerne les images de conteneur créées conformément à la procédure fournie dans la documentation Xilinx. Si vous utilisez cet exemple, remplacez image par votre propre image, et copiez vos fichiers vidéo dans l'instance dans le répertoire /home/ec2-user.
