Unicastrtp not getting video Asterisk 18.18.0 chan_sip

Hello,

I am trying to use linphone and UnicastRTP to get video.
== Using SIP VIDEO CoS mark 6
== Using SIP RTP CoS mark 5
– Executing [116@smvoice-sip:1] Answer(“SIP/123-000001bf”, “”) in new stack
– Executing [116@smvoice-sip:2] Dial(“SIP/123-000001bf”, “UnicastRTP/127.0.0.1:50000”) in new stack

[May 12 08:48:54] WARNING[1282136][C-00006701]: channel.c:5765 set_format: Unable to find a codec translation path: (ulaw) → (h264)

I get this error about the code translation???

My extension for linphone has:
disallow=all
allow=h264
allow=ulaw
allow=alaw
allow=gsm
videosupport=yes

my asterisk sip.conf has videosupport=yes

How do I get video with UnicastRTP ?

UnicastRTP does not support video.

3

So MulticastRTP and UnicastRTP both dont support video ? That is dissapointing.

How then can I get a “video” call out to something else like a VLC that will do multicasting ?
Thanks

Jerry

From a built-in method there is no direct mechanism. You could throw it to a SIP client that could maybe provide it, though I don’t think I’ve ever heard of anyone doing that.

5

I do have WEbRTC working. Is there a way to get that to a VLC or ffmpeg ?
Thanks

I don’t have any information or thoughts on doing this outside of Asterisk.
