     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.
