Si vous ne disposez pas encore de votre propre composant vidéo à la demande (VOD), vous pouvez utiliser l'API Transcoder pour créer un fichier manifeste VOD et segmenter des fichiers pouvant être utilisés avec l'API Video Stitcher. C'est totalement facultatif.
Le fichier manifeste VOD est utilisé comme URI source dans une configuration VOD. Les formats DASH et HLS sont acceptés.
Voici un exemple de configuration de tâche que vous pouvez utiliser avec API Transcoder pour créer les fichiers VOD. Pour en savoir plus, consultez Créer des tâches avec des configurations ad hoc Vous devez activer l'API Transcoder dans votre projet Google Cloud. Pour en savoir plus, consultez la section Avant de commencer.
