[Asterisk-video] No Audio . Video when running app_mp4

[Atle Samuelsen]

Yo,

Found a coredump for you ;) Under asterisk 1.4.2 and app_mp4.c. I´m
useing a good video-phone  that runs H264 against asterisk.

a backtrace of the coredump looks like this: 

#0  0x0024b58c in memcpy () from /lib/tls/libc.so.6
(gdb) bt
#0  0x0024b58c in memcpy () from /lib/tls/libc.so.6
