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

[Borja SIXTO]

I have tested it.
Is seems to works too.
I think here a short delay (between the voice and the video) if I 
reprompt the message recorded.

I have updated the binary package in the www.i6net.com website (select 
modified modules to install the app_h324m with the patch).

You can test it in live here (with the Video VoiceXML call2web) :
- By calling to : +34912104506 (spanish number)
- And seeing the result here too :
