asterisk users - Dec 2010 - Converting asterisk h264 recordings

Hello,

 

We are setting up an asterisk system for voicemail with video possibilities.
We are not using the voicemail app, but rather writing our own dialplan
logic. The part of recording, and replaying, the voicemail works, and we
receive both an h264 and an wav-file. What I now wonder is how to convert
these into one file playable by a (standard) media player. I have not found
any real good leads by google:ing, but of course I may have missed it
 Any
pointers?

 

BR,

Torbj?rn Abrahamsson

Perhaps this would work for you?

Torbj?rn,

I don't have experience with asterisk in this regard, but I would
guess that what you have is an elementary stream and not a transport
stream.  I believe that VLC could play it back for you.

Outside of that, I would look at using ffmpeg.  It may do what you want.

Here is some documentation on dealing with files like I suspect you
have: http://processors.wiki.ti.com/index.php/Encoding_and_decoding_DVEVM_clips

The link has absolutely nothing to do with Asterisk, but it may be useful.

This might be better but it won't be easy to obtain:
http://www.i6net.com/2006/08/24/ffasterisk-10-new-video-file-converter-released/

"This tool generate video contents for asterisk (to add video clips *.h263
for the asterisk
VoiceMail application for example, or create new video service for asterisk).
The original file
format could be MOV QuickTime files.

It?s tested with the SIP Video Phones WengoPhone and Kapanga.
...
This product is now discontinued."

In general do take a look at the Wiki - and enhance it where you see fit:
http://www.voip-info.org/wiki/view/Asterisk+video

And do note that there is a dedicated asterisk-video mailing list!

Philipp

P.S.: I do remember a dedicated Video web page for Asterisk patches that
included a
transcoding feature, but can't find it anymore - should be archived in the
asterisk-video
mailing list.
