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

[Borja SIXTO]

The new full package is on line now.

2 ways to install the Fonteventa applications :

- Original sources from the sip.fonteventa.com website (svn), without 
modifications.
- Modified versions (modifications pending, testing or not approved for 
the moment).

The installation script ask you the select one of this options.


The modifications delivered are :

- app_mp4 and app_rtsp, specific modifications to handle the DTMF 
bargein (I am waiting to the modification proposed in the ticket list) 
and the speech (ASR) streaming processing during the video playing (send 
the audio packets to the Asterisk speech API, if the result is 
available, the prompt is skipped).
- app_h324m, with the modification proposed by Sven and the ALAW forced 
for European use. This week I will propose a configuration file 
(h324m.conf) to parameter : G711 law, debug level and for the future to 
add more initial parameters : I will propose this modification to the 
ticket list too.

I will add a short text description about this modifications in the next 
package.
Thanks Sergio for the feedback.

Regards,


Tech from i6net
