No video on Tandberg E20 (or EX90) with Stream Manager

[alexandercoachman]

Hi guys,

i have an another problem since 2 weeks what i cant resolve. I have a Tandberg E20 videoconferencing system. I'd like to play with this client a simple video file from Genesys SIP Server and Stream Manager. I have a very simple routing strategy with one "play announcement" block. I loaded this strategy on a routing point and i call this routing point with CounterPath Bria and it works.

Lets see how i convert my video file:

First, i downloaded a sample H264 HD 720p file. I saw that its in 24FPS, so i converted it with Xilisoft Video Converter to 30FPS, because i had problems without this step. Now i extract the audio file from this mp4 video file with mplayer, and convert it to 8kHz 16bit Mono Stream, named to [b]pcmu.wav[/b].

Now i will convert the video with mencoder with the following options:
[i]C:\Program Files\Sgi's Video Converter GUI\Mplayer>[/i][b]mencoder h264_hd_720p_30fps_cif.mp4 -vf scale=352:288 -of rawvideo -ofps 30000/1001 -nosound -o 10 -ovc x264 -x264encopts subq=7:me=umh:partitions=all:keyint=25:bframes=0:nob_adapt:nocabac:level_idc=13[/b]

I use level_idc=13, because i saw in the SDP from Tandberg E20:

a=rtpmap:97 H264/90000
a=fmtp:97 [b]profile-level-id=4280[u]0d[/u][/b];max-br=906;max-mbps=40500;max-fs=1344;max-smbps=40500
a=rtpmap:98 H264/90000
a=fmtp:98 [b]profile-level-id=4280[u]0d[/u][/b];max-br=906;max-mbps=40500;max-fs=1344;max-smbps=40500;packetization-mode=1

(When i set the max-bitrate to 800, it doesnt helped me, but the mencoders default value is 576.)

I zipped these two file with smzip:

smzip -ac pcmu [b]pcmu.wav[/b] [b]h264_42e00d=1[/b]

and copied it to the announcements folder. When i call from E20, it doesnt show me a video, i can hear only the voice. But when i call it with CounterPath Bria, it works properly, i can see the video too.

SM options:

Hi Alex,

I checked the logs but not sure where the problem is One idea - Tandberg controls media streaming using RFC5168 (SIP INFO messages with XML document inside) but this RFC is supported neither by SIP Server nor by Stream Manager...

Hello

Have you tried disabling BFCP on the Tandbergs and trying again? IN the logs you have posted i do see two m=video attributes in the SDP with two different ports on the E20 logs. Do not know if stream manager supports this and how does it know which port on the E20 to connect to? Maybe I am way off

Dear René,

now the E20 client plays our H263 video. I hate H264 videos now  H263 will be good for us. Another problem with playing two or moe videos, one after the other.. I opened a new topic to this. We have not enough time to play with H264.

Dear vmeno000, thanks for your advice, i will try it soon!

[b]Thanks for all...[/b]
