Funky errors using MPMoviePlayerViewController

Question

¿Alguien sabe lo que significan estos errores? Lo entiendo cuando hago clic en un botón para reproducir un video (descargue a través de Internet a pedido).

El problema que tengo es que mi video se reproduce sin audio. De hecho, la barra de volumen de audio se va completamente en carga.

Tengo la sensación de que tiene algo que ver con estos errores, je.

Answer 1

HDA es un formato de audio (http://en.wikipedia.org/wiki/Intel_High_Definition_Audio). Dado que la Mac utiliza diferentes controladores de audio y video, ha habido ciertas situaciones en las que los tipos de audio o video no se reproducirán en el simulador ya que en realidad no implementa la pila completa de software que se encuentra en el dispositivo. En este caso, parece que el controlador para el audio HDA ​​que utilizan sus videos no está disponible en Mac.

Esto no significa que su Mac no pueda reproducir audio HDA ​​solo que el complemento exacto que iOS está buscando no está disponible. Por lo tanto, solo deshabilita la parte de audio del video y continúa y reproduce lo que puede.

Históricamente solías no poder reproducir videos de YouTube en el simulador mientras que funcionaban bien en el dispositivo. De nuevo, esto fue un caso de un complemento faltante. Las versiones más nuevas del simulador de iOS tienen un complemento que se traduce entre las capacidades de la Mac y cómo el simulador desea acceder a ellas.

¿Agregó los marcos mencionados en la configuración de compilación de su proyecto?

Para mí, parece que los marcos están referenciados sin estar presentes en su binario.

Para añadir los marcos necesarios que se pueden hacer los siguientes pasos:

1. abrir el proyecto en Xcode
2. Haga clic en el elemento raíz en el navegador de proyectos
3. Seleccione su destino
4. Ir a Build Phases y ampliar Link with libraries
5. Asegúrese de que los marcos mencionados se enumeran aquí.
6. Si no están presentes añadir ellos y reconstruir su aplicación

Answer 3

La barra de volumen se supone que se vaya - se comporta como si estuviera conectado a un muelle de salida de línea de crudo dispositivo. Asegúrese de que el sonido de su computadora también esté encendido ...

En cuanto a los errores, tengo un problema similar con mi aplicación, que a pesar de recibir una serie de errores similar, no está teniendo ningún problema real. La regla de oro es que si funciona en el dispositivo, estás bien.
