Hi all, I install app_mp4 at Asterisk 1.4.21.2.

When I call mp4play in dialpaly as bellow:
exten => 999,3,mp4play(/usr/vxi/asrvideo/video/welcome.3gp)

Asterisk is crashed. Bellow is console message
[Feb 26 11:21:18] NOTICE[12009]: chan_sip.c:12669 handle_response_peerpoke: Peer 'cc100' is now Reachable. (102ms / 2000ms)

I executes ldd to show
ldd /usr/lib/asterisk/modules/app_mp4.so

libpthread.so.0 => /lib/tls/i686/cmov/libpthread.so.0 (0xb7f4c000)
libc.so.6 => /lib/tls/i686/cmov/libc.so.6 (0xb7dfd000)
/lib/ld-linux.so.2 (0xb7f75000)

So I think I may missed some library in mpeg4ip. Please anyone advise where can I get the right mpeg4ip binary package? My current mpeg4ip is install by apt-get install. I use Ubuntu 804. Thanks for any advise!
