vlcj - Logotipo

Mejoremos aún más la aplicación en la que actualizaremos vlcj - Capítulo de marquesina con soporte de Logo. Podemos agregar un texto como superposición sobre el video.

Crea y construye un logo

Logo logo = Logo.logo()
   .file(LOGO_PATH)
   .position(LogoPosition.TOP_LEFT)
   .opacity(0.3f)
   .enable();

Establecer logotipo

Ahora, usando el método del logotipo, podemos establecer fácilmente un logotipo en nuestro video en nuestra aplicación usando la siguiente sintaxis:

mediaPlayerComponent.mediaPlayer().logo().set(logo);

Ejemplo

Abra el proyecto mediaPlayer como se creó en el capítulo Configuración del entorno en Eclipse.
