¿Se puede desconectar VideoView y volver a conectarlo sin detener la transmisión? (4)
Estoy construyendo una aplicación donde el usuario hace clic en un botón para mostrar un video a pantalla completa. Inicialmente, el video se adjunta a una vista dentro de un ViewPager. Para poder mostrarlo en pantalla completa, lo desconecto de su elemento principal y lo vuelvo a conectar a la vista raíz. Esto funciona bien, excepto cuando el video se cambia a pantalla completa mientras se reproduce. Cuando desconecto un VideoView que se reproduce, simplemente se detiene y necesito reiniciarlo. Esto no es aceptable ya que el video inicia el almacenamiento en búfer antes del currículum. Aquí la parte del código donde se realiza el desmontaje:
final ViewGroup parent = (ViewGroup) findViewById(R.id.parent);
final ViewGroup root = (ViewGroup) findViewById(R.id.root);
Button b = (Button) findViewById(R.id.button);
b.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
parent.removeView(mVideoView);
LayoutParams lp = new FrameLayout.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT);
root.addView(mVideoView, lp);
}
});
Dependiendo del dispositivo, tengo un error de registro diferente. Probablemente porque el reproductor de video real es proporcionado por el fabricante y no por el SDK de Android. Aquí están los registros de errores de un Nexus 7:
10-30 20:26:18.618: D/NvOsDebugPrintf(124): NvMMDecTVMRDestroyParser Begin

No he podido separar el video sin detenerlo. Intenté usar SurfaceView o TextureView sin éxito.
También traté de encontrar un reproductor de video de terceros. Encontré uno comercial ( http://www.vitamio.org/ ) que no puedo usar realmente por razones comerciales. Encontré uno de código abierto, que no se actualizó en el último año ( https://code.google.com/p/dolphin-player/ ).
Actualmente me estoy orientando a Android 4.2 o mejor solo en la tableta.
Tenga en cuenta que ViewPager no es pantalla completa. Entonces no puedo usar LayoutParams para hacer que el video sea de pantalla completa. Necesito eliminar VideoView del padre en ViewPager y agregarlo a la vista raíz para poder mostrarlo en pantalla completa.
La URL con la que estoy probando: http://bellvps1.cpl.delvenetworks.com/media/e1b3e24ecb944abd8f4ed823a0b76ddc/68f78d35296243bfb46d2418f03f2fd0/bande-annonce---the-secret-life-of-walter-mitty-1-9efcc5c6e52ac07a3edf84a1b21967995b7796a2.m3u8
No lo he intentado, pero espero que te pueda ayudar.
final ViewGroup parent = (ViewGroup) findViewById(R.id.parent);
final ViewGroup root = (ViewGroup) findViewById(R.id.root);//assuming this full screen
Button b = (Button) findViewById(R.id.button);
b.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// parent.removeView(mVideoView);
LayoutParams parentParam = parent.getLayoutParams();
parentParam.height = root.getLayoutParams().height;
parentParam.width = root.getLayoutParams().width;
parent.setLayoutParams(parentParam);
LayoutParams lp = new FrameLayout.LayoutParams(
LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT);
root.addView(mVideoView, lp);
}
});
Gracias.
No sé los detalles de cómo funciona el reproductor de video, pero mi corazonada es que tienes que:
Override onSaveInstanceState to save the place in the video (maybe a timestamp?)
Override onRestoreInstanceState to reload the video and seek to the point saved in step 1
use textureview con esta modificación:
@Override
public void onSurfaceTextureUpdated(SurfaceTexture surfaceTexture) {
if (mediaPlayer != null) {
mediaPlayer.setSurface(new Surface (surfaceTexture));}
}

Este efecto se puede lograr usando un TextureView . Esencialmente, lo que hace es crear una instancia de MediaPlayer , prepare() y start (), luego puede usar el método MediaPlayer.setSurface() en cualquier TextureView para cambiar la superficie mientras se reproduce el video sin cambios en el estado del objeto MediaPlayer . como se indica en los documentos de android para el método setSurface() :
This method can be called in any state and calling it does not change the object state.
Tenga en cuenta que esta implementación es para demostración, probablemente debería usar mediaplayer.prepareAsync() y esperar una devolución de llamada con onPreparedListener() , también deberá establecer las dimensiones correctas para el segundo TextureView acuerdo con su tamaño de video, manejar cambios de orientación y, por supuesto, manejar excepciones adecuadamente donde sea necesario.
