[Asterisk-video] Asterisk and video contents for 3G network

[tech at i6net.com]

I6net is goging to publish this week a new opensource video conversion tool :

FFasterisk is a free video converting tool for Asterisk PBX. This software is
available under the GNU General Public License (GPL).

FFasterisk is a powerful video converter, which can convert video formats
including MOV, 3GP to Asterisk (H263 and WAV) and vice versa. FFasterisk is an
application using ffmpeg's features. It currently carries out the following
tasks:

- Audio decoding form a video file to WAV/PCM file format
- Video encoding form a video file to H263 asterisk file format
- Audio/video encoding form video asterisk files (wav+h263) to video file format
- Codec and RTP parameters can be cusomized (for SIPphones or VOIP providers)

This tool will be able to generate video contents for asterisk (to add video
clips *.h263 for the asterisk VoiceMail application for example, or create new
video services for asterisk).

It was tested with the SIP Video Phones WengoPhone and Kapanga.

We need contributors to improve the tool and add new encoding profiles for more
Sip Video Phone or 3G equipements.

> Hi Philipe.
> 3gp and 3gp2 are NOT video codec. there are ISO format of media files like
> .avi
> In the 3gp file, you have the audio part that is either h263 or AAC, and the
> video part which is h263 or MPEG4 ( AVC)
> so those information as the ISO describes it are writen inside the file.
> Some phone don't have the capability of decoding MPEG4. so if you give them a
> 3GP file with MPEG4 codec for the video, they WONT play it...
> the codec that could be used for the audio are AMR-NB (up to 12.2kb)
> mandatory, AMR-WB, g.723.1, AAC...
