[Linphone-users] About video

Hi, Conrad

I've already included the lines related to h263 and h263p in my sip.conf and that's why i think that the problem isn't in Asterisk.

Probably, my linphone doesn't support h263p, linphone doesn't support h263 or both have those codec problems.
Now, to solve this, or at least to discard problem sources, I'd like to use an h263 codec in linphone (as I can't change my phone codecs).

Do you know which versions of Asterisk use Theora or, preferably, mp4? Does it natively or do I have to include the codec as a module? (Sorry, but I'm still a newbie in Asterisk terms)
I could try to use those codecs to see if my phone admits one of them.

Muchas gracias por la ayuda.
Saludos madrileƱos :-D

Depends on what Asterisk version you have. I have a rather 1.2 version which
can do h263p. The key is to enable it. Check out my sip.conf

videosupport=yes                ; Turn on support for SIP video
disallow=all                    ; Windows Messenger will choose wrong codecs
;allow=speex                    ; mag Sipgate z.B. nicht, darum ausgeklammert
allow=gsm       ; war aktiviert
allow=alaw      ; war aktiviert
allow=ulaw      ; war aktiviert   codec order is respected only in [general]

I have h263 and h263 enabled (and h261 for old Ekiga). Don't forget to turn
videosupport on.

Then it will work. Recent versions of Asterisk can convert theora and mpeg4
too but I havn't tested this yet.

Saludos desde Berlin :-)  Dime si tienes exito
