J'essaie de télécharger tous les fichiers disponibles qui sont différentes qualités d'une seule vidéo en utilisant l'API YouTube, mais chaque URL que je suis pour télécharger les résultats vidéo dans un 403.

Comme vous pouvez le voir sur la wget
sortie, les URL semblent syntaxiquement correctes, mais les serveurs renvoient toujours un 403. Cela se produit quelle que soit la vidéo que j'essaie.
J'essaie de télécharger les fichiers à partir de la même adresse IP et du même ordinateur avec lesquels j'ai généré les liens. Des idées?
