Asterisk12 and sipML5 video support

Hi,

is it possible to send video each other on asterisk12 and sipML5 demo site?
I can hear audio but video is black screen…
I set sip.conf like this,

[general]
videosupport=yes
[6001]
host=dynamic
secret=1234
context=from-internal
type=friend
encryption=yes
avpf=yes
force_avp=yes
icesupport=yes
directmedia=no
disallow=all
allow=ulaw
allow=alaw
allow=gsm
allow=h261
allow=h263
allow=h264
allow=vp8
dtlsenable=yes
dtlsverify=fingerprint
dtlscertfile=/etc/asterisk/keys/asterisk.pem
dtlscafile=/etc/asterisk/keys/ca.crt
dtlssetup=actpass

[6002]
host=dynamic
secret=1234
context=from-internal
type=friend
encryption=yes
avpf=yes
force_avp=yes
icesupport=yes
directmedia=no
disallow=all
allow=ulaw
allow=alaw
allow=gsm
allow=h261
allow=h263
allow=h264
allow=vp8
dtlsenable=yes
dtlsverify=fingerprint
dtlscertfile=/etc/asterisk/keys/asterisk.pem
dtlscafile=/etc/asterisk/keys/ca.crt
dtlssetup=actpass

my environment,
sipml5 demo site
sipml5.org/call.htm?svn=224

Thank you for your cooperation.

Enable videosupport on each peer. set the codecs and try again. In the past only treid echo test with video but no peer to peer so dont know really what is happening, maybe a SIP debug will help.
