Tengo una clase de video de escenario que la utilizo para reproducir un video en una tableta, pero cada vez que reproduzco un video, la pantalla de la tableta parpadea un par de veces (se pone negra y sale unas cuatro veces). Me pregunto qué podría estar causando esto Hace esto mientras cambio a la vista con la reproducción del video. La URL del video se pasa a la vista de video mxml. Estoy usando flex 4.6 y una tableta Android (EEE transformer prime).Parpadeo con StageVideo en una tableta Android?

Aquí está mi código de la opinión de que reproduce el vídeo cuando el vídeo se completa

Agregado Actualización de código tener un oyente StageVideoEvent y simplifie d para una vista (también para conocer la renderMode será el director)

El único otro punto de vista en esta aplicación sólo tiene un botón con navigator.pushView (Copyofvideo, null, null); y cada vez que se hace clic en el botón, la pantalla parpadea y luego se reproduce el video.
¿Pudo resolver la pantalla parpadeante y negra? – mik
