poner audio a una imagen online

Question

Estoy creando un video a partir de una imagen y un sonido mp4 en mi tarjeta sd en Android desde jcodec. Recibo un video de salida pero no hay voz y el video se reproduce en vlc, pero en el reproductor de Android bucle continuo por favor ayúdenme

El siguiente es mi segmento de código
