[Asterisk-video] Help install app_mp4.c with Asterisk 1.4.6 and Centos 5.0 Part II

[Klaus Darilion]

Thats basically how it got it working too.

You can also use "ldd" to find out if all the needed libraries are 
available, e.g.:

~# ldd /usr/lib/asterisk/modules/app_mp4.so
         libmp4.so.0 => /usr/local/lib/libmp4.so.0 (0xb7f01000)
         libmp4v2.so.0 => /usr/local/lib/libmp4v2.so.0 (0xb7e20000)
         libc.so.6 => /lib/tls/libc.so.6 (0xb7ceb000)
         libdl.so.2 => /lib/tls/libdl.so.2 (0xb7ce8000)
         libstdc++.so.5 => /usr/lib/libstdc++.so.5 (0xb7c2e000)
         libm.so.6 => /lib/tls/libm.so.6 (0xb7c0c000)
         libgcc_s.so.1 => /lib/libgcc_s.so.1 (0xb7c03000)
         /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x80000000)

there shouldn't be any missing libraries reported.

after editing do not forget to execute "ldconfig" once.
