H264 High profile supported?

Postby shubert69 » Tue Dec 09, 2014 12:44 pm

Hi Folks,

I've noticed that I cannot successfully establish a H.264 High profile video call between two video devices thru the Asterisk. Although a H264 Base Profile can be established successfully.

Is there some specific configuration that is required on the Asterisk?

This is the Video portion of the orignal INVITE SDP to the Asterisk

m=video 50004 RTP/AVP 99 98
Bandwidth Information (b): TIAS:256000
Bandwidth Information (b): AS:266
Media Attribute (a): maxprate:32.0
Media Attribute (a): rtcp:50005
Media Attribute (a): sendrecv
Media Attribute (a): rtpmap:99 H264/90000
Media Attribute (a): fmtp:99 profile-level-id=64001f; max-mbps=108000; max-fs=3600; max-br=5125; packetization-mode=1
Media Attribute (a): rtpmap:98 H264/90000
Media Attribute (a): fmtp:98 profile-level-id=64001f; max-mbps=108000; max-fs=3600; max-br=5125; packetization-mode=0

And the Asterisk send the INVITE/SDP to the receiving Unit:

Media Description, name and address (m): video 16348 RTP/AVP 98
Media Attribute (a): rtpmap:98 H264/90000
Media Attribute (a): sendrecv

From a Audio can be connected, just no video.
