PHP Code Samples

Los siguientes ejemplos de código, que utilizan la Biblioteca cliente de API de Google para PHP, están disponibles para YouTube Data API.

Subir una miniatura personalizada para un video

Este ejemplo de código muestra cómo subir una miniatura de video personalizada a YouTube y establecerla para un video.

El ejemplo de código a continuación invoca el método youtube.thumbnails.set de la API con el parámetro videoId establecido en una identificación de video para utilizar una imagen personalizada como miniatura del video. Al subir la imagen, el programa utiliza la clase Google_MediaFileUpload con el parámetro resumable upload establecido en true para hacerlo pieza por pieza, lo que permite realizar nuevos intentos para reanudar la subida desde un punto cercano al intento previo cuando se produjo el error. Esta característica resulta útil para los programas que necesitan subir archivos grandes.

 * 2. It sets the uploaded image as a custom thumbnail to the video by
 *    calling the API's "youtube.thumbnails.set" method
