Question

FMG / SIP 2-way Video call

Hi,

I am trying to get two way video conference call from Sip phone to FMS app via FMG. Video stream from Sip phone to sample FMS application via FMG is working fine. But video stream from FMS application to Sip phone is buggy (It shows only horizontal lines & nothing else). I tried with various setting in videoquality.xml file but no success.

Below are my FMG settings.

Are there any other settings I am missing to solve the video isues?

Thanks

Sip.xml

                                <codecID> speex </codecID>

                                <codecID deviceId="GenericVtcDevice" qualityLevelId="medium"> H264 </codecID>

                        </supportedCodecs>

                </Profile>

Videoquality.xml is kept on default.

Note:- Also tried with "low" and "high" quality level Id. All servers are local, so no network issue.

Sample Flash Phone doesn't publish H.264 video captured from local camra and audio-only stream is sent; therefore, video doesn't display on the SIP phone..

However, one may update the flash phone source to publish H.264 Video captured from camera.

One reference on how to enable H.264 encoding from flash client is: http://forums.adobe.com/message/4300852

Hi Pankaj,

Thanks for the quick response. Perhaps it was my mistake I didn't elaborate more. I have created a sample FMS application which publish / receieve the H.264 stream to / from FMG. I am not using sample app provided by FMG. Kindly let me know if you need any more settings from my side.

Thanks.

1. Do you see an error meg in core.log (fmg) during/after call is over. This is to ascertain that video codec coming from your phone app is indeed H.264.

2. Does RTP filter using wireshark shows video packets going out of FMG to your SIP phone?

3. What is the SIP video phone/ VC device being used by you?( model make).

Many legacy VC devices don't playback video encoded by FP. However, s are found to be more robust in the playback input.

However, if your softphone still doesn't play h.264 from FMG well;you might want to give it a after changing packetization mode of how fmg sends data to soft client. (in videoqualitylevel.xml)

<qualityLevel qualityLevelId="medium" fmtp="profile-level-id=420016;max-br=500;packetization-mode=1"/>
