Funky errores usando MPMoviePlayerViewController

¿Alguien sabe lo que significa este error? Recibo esto cuando hago clic en un button para reproducir un video (descarga a través del estilo de Internet bajo demanda).

El problema que estoy teniendo es que mi video se reproduce sin audio. De hecho, la barra de volumen de audio desaparece completamente al cargarse.

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

HDA es un formatting de audio (http://en.wikipedia.org/wiki/Intel_High_Definition_Audio). Como la Mac usa diferentes controlleres de audio y video, ha habido ciertas situaciones en las que los types de audio o video no se reproducirán en el simulador, ya que en realidad no implementa la stack de software completa que se encuentra en el dispositivo. En este caso, parece que el controller para el audio HDA ​​que usan tus videos no está disponible en Mac.

Esto no significa que su Mac no pueda reproducir audio HDA ​​simplemente porque el complemento exacto que iOS está buscando no está disponible. Por lo tanto, simplemente desactiva la parte de audio del video y sigue adelante y reproduce lo que puede.

Históricamente solía no poder reproducir videos de YouTube en el simulador mientras funcionaban bien en el dispositivo. Esto nuevamente fue un caso de un complemento faltante. Las versiones más recientes del simulador de iOS tienen un plugin que traduce entre las capacidades de Mac y cómo el simulador quiere acceder a ellas.

¿Añadiste los frameworks mencionados en las configuraciones de construcción de tu proyecto?

Para mí, parece que los frameworks están referencedos sin estar presentes en su binary.

Para agregar los frameworks necesarios, puede realizar los siguientes pasos:

  1. Abra su proyecto en Xcode
  2. Haga clic en el elemento raíz en el browser del proyecto.
  3. Seleccione su objective
  4. Vaya a Build Phases y expanda Link with libraries
  5. Asegúrese de que los frameworks mencionados se enumeran aquí.
  6. Si no están presentes, agrégalos y reconstruye tu aplicación.

espero que esto ayude

Se supone que la barra de volumen desaparece, se comporta como si estuviera conectada a un dispositivo de línea de salida crudo. Asegúrate de que el sonido de tu computadora esté encendido también …

En cuanto a los errores, tengo un problema similar con mi aplicación, que a pesar de tener una cantidad similar de errores, no tiene problemas reales. La regla general es que si funciona en el dispositivo, está bien.
