| best software versions fro video
projects? |

Hi all,
after a lot of time I have again the time to play a bit with
video
support in *... I hope to be helpful at least in testing and
debugging.
I'm rebuilding all the stuff, and I was thinking why not
writing a list
of software versions used, since all the libs involved here
are
under very active development...
for example, what asterisk version is recommended?
I'm using 1.4.9 and ported AMR patch to it by hand...
but maybe is better a svn trunk version?
for those that wants to play with amr, why not making an
AMR
patch for a specific * version ?
what ffmpeg version is better to use (at least for avoiding
problems with API changes)? mpeg4ip? etc etc
any comment on that?
best regards,
matteo.

Hi Matteo,
I recognize all your questions.
I've been playing with asterisk for over a year now, but only needed video and AMR support since a few months.
Have tried to implement the amr codec as described by Paul (
http://lists.digium.com/pipermail/asterisk-dev/2007-March/026446.html
)
All compiles well, but I don't get it to transcode. AMR in pass through does work with this patch.
Does your implementation of AMR on version 1.4.9 work? Does it transcode to g711 for instance?
If so, could you maybe make a patch of this (using 'svn diff')?
And there's also the issue of H263-2000 (aka H263++). As it is, * doesn't understand this codec in your sdp's.
Would it be a lot of work to add this? Even only in pass through?
Looking forward to putting our experience together...
Koen

Hi Koen!
Which SIP client do you use? Or asked in another way - which
SIP client
does support AMR?

I don't know if it works, no client to test with.
Btw, I've ported it by just applying by hand the contents of
the diff file.
right now I want to build a system with all sergio stuff and
confiance stuff
to play with.... then star real work 
regards,
matteo.

Klaus,
I don't use a SIP phone.
I'm working with a Dilithium 3G gateway and some other system that provides video content (and speaks amr).
AMR supporting SIP phones are indeed hard to find, especially in OSS, because of licensing restrictions.
For the record, I know there's a licensing issue with amr that needs to be handled.
It's also the main reason why this codec is not in the asterisk package (yet).
But in my opinion, since VoiceAge provides an amr implementation for free to be used in research and development (
http://www.voiceage.com/freecodecs.php), we could at least try to make it work in asterisk.
For those who are wondering, here are the licensing terms for amr-nb:
http://www.voiceage.com/amr_licterms.php
I guess the biggest problem is the initial fee of $6.500. Or am I missing something else?
Have to go ... we'll get on with this later
Ciao,
Koen

Matteo,
Are we talking about the same diff file from Paul Bagyenda?
And what's sergio stuff?
