Audio not coming in MPEG-4

kshemendra
Hi,

    I tried to play MPEG-4 video on mini2440 on Linux. If I play MPEG-2
files, audio and video both are working fine. Where as when I tried to
play MPEG-4 video, only video is displayed and audio is not coming.
Could anyone help me in solving the problem.

Regards
