Yes, it is possible. The linux program is untrunc, and you might have to
compile it yourself. http://vcg.isti.cnr.it/~ponchio/untrunc.php.
Essentially, it reconstructs it the best it can using the information to go
by off of another MP4 file - it works best if you have a working MP4 file
from the same system/settings.
