Maybe. I believe that the headers of Asterisk (installed to
/usr/include/asterisk ) include anything you need to build an external
module. Though I wouldn't be completely surprised if those were not
complete in 1.4.13 .

Furthermore, they instruct you to re-run configure, but then they don't
really rely on that and manually add the extra libraries to the build
line. I don't see why you'll need to re-run configure if you already
have the built source directory.

Building it independently would be something along the lines of:

  gcc $CFLAGS -DAST_MODULE="app_mp4" -shared -o app_mp4.so app_mp4.c -lmp4 -lmp4v2 

Where CFLAGS would typically be -O2  and such.

This should hopefully build you app_mp4.so . Next, make sure it does not
load automatically until you verified it to work: in modules.conf:

  unload => app_mp4.so

At this point you may crash Asterisk. So do it in the off-hours or on a
different instance.

Try loading it manually in the Asterisk CLI:

  module load app_mp4.so

Check if it actually works.

If all goes well, disable the "unload" entry in modules.conf .
