      I am trying to get the "Mega Phone" demo working on my office PBX
but there seems to be a problem when trying to set the default bridge to
sfu mode.  I have the following configuration in confbridge.conf in the
default_bridge section: video_mode = sfu but when I do a "confbridge
show profile bridge default_bridge" I see:

Video Mode:           no video

      I can change it to follow_talker, last_marked or first_marked and
it does change, it is just the sfu option that does not seem to be
valid.  I am using Asterisk 15.1.2 for my testing.  I even tried to
force the option via Dialplan:

[ Context 'ext' created by 'pbx_config' ]
    '1000' =>         1. Answer()
[extensions.conf:0]
                      2. Set(CONFBRIDGE(bridge,video_mode)=sfu)
[extensions.conf:0]
                      3. ConfBridge(guest) [extensions.conf:0]
                      4. Hangup() [extensions.conf:0]

      But I get no video at all on the conference.

      Any ideas?
The CLI command doesn't have sfu as a mapping right now. Please file an
issue[1] for that. As for video there's additional configuration that
you have to do in pjsip.conf in order to allow the streams. I'd suggest
following the blog post[2] which has known working configuration.

I followed the blog post and I can get video from the conference if I configure the bridge as follow_talker so I know everything is working on the pjsip side. The only problem is that video_mode = sfu is apparently not valid in either confbridge.conf or via the dialplan and I get no video with that option.
