Comentarios

El evento SourceRequested se desencadena cuando un usuario selecciona el acceso Dispositivos en una aplicación habilitada para Reproducir a. Proporcione el audio, el vídeo o la imagen que Reproducir a transmitirá a un dispositivo de destino durante el evento SourceRequested .

Si no proporcionas un origen multimedia en un plazo de 200 milisegundos, el evento SourceRequested agotará el tiempo de espera y el acceso Dispositivos no mostrará ningún destino de Play To para tu aplicación.

El evento SourceRequested se produce antes de que el usuario seleccione el dispositivo de destino. Una vez que el usuario ha seleccionado el dispositivo de destino, se desencadena el evento SourceSelected . Si el usuario sale del acceso Dispositivos sin seleccionar un dispositivo de destino, no se desencadena el evento SourceSelected .

Se aplica a
