[Asterisk-video] mp4save(): different audio and video lengths

[Borja SIXTO]

Sorry, Sergio,

My packaging script have overwritten the full sources (of the original 
sources).
I have made the corrections and I have generated a new package with the 
sources tagged modified.
It will be on line in few minutes.

Sorry for this inconvenience.
