MediaConvert exemples d'utilisation SDK pour Kotlin
Les exemples de code suivants vous montrent comment effectuer des actions et implémenter des scénarios courants en utilisant le AWS SDK for Kotlin with MediaConvert.
Les actions sont des extraits de code de programmes plus larges et doivent être exécutées dans leur contexte. Alors que les actions vous indiquent comment appeler des fonctions de service individuelles, vous pouvez les voir en contexte dans leurs scénarios associés et dans des exemples interservices.
Les Scénarios sont des exemples de code qui vous montrent comment accomplir une tâche spécifique en appelant plusieurs fonctions au sein d’un même service.
Chaque exemple inclut un lien vers GitHub, où vous pouvez trouver des instructions sur la façon de configurer et d'exécuter le code en contexte.
