Re: [FFmpeg-user] FFMPEG to Tangberg video conferencing

[Davood Falahati]

Moritz,

Thank you for your reply. As I can see in device's web-page panel, here are
the specifications about the device is attached to this mail. Device is
called TANDBERG, sorry for the typo. It is a video conferencing device with
complete sets of I/O peripherals. I need to connect to it with ffmpeg and
see its content as well.


Thank you,
Davood

adding info to the thread

a decent history on the H.323 video conferencing protocol suite

https://en.wikipedia.org/wiki/H.323

an open source H.323 video codec library

http://www.h323plus.org/

google for "H.323 open source clients" you may find helpfiul info on how to 
join a h.323 conference call that does not require another hardware end point.

i'm not aware of H.323 support in ffmpeg

A H.323 application that wishes to connect to another H.323 user, will connect 
to that machine on both ports 1503 and 1720. Using these two connections the 
applications negotiate UDP ports to use for data transfer.

Wow, a screenshot of the system settings. I actually wanted to know how
you access the stream from your PC.

You're making it as difficult as possible for us, aren't you? ;-) The
company is called Tandberg, the device is actually called Tandberg
Profile 6000 MXP, that's the info we can make use of.

Well, I went to the trouble of doing what I asked you to, and found the
device documentation:

https://www.vcwarehouse.com/v/vspfiles/Data_Sheets/tandberg_6000_mxp/videoconferencing-tandberg-profile-6000-mxp-user-manual.pdf

It points out that you can access your stream under the web page
http://http://10.10.1.23/showstream.ssi

If you open that page in your web browser, it will try to show a stream
with the QuickTime plugin. (I have found only devices without streams
running, unfortunately.) Alternatively, it offers you this:

  "If you can not see any stream above (unless streaming is not
  running), download QuickTime™ 4 (or later) plugin or other streaming
  client that understands SDP and/or can handle RTP.

  If you have no SDP capable client, but one that understands RTP.
  Direct it/them to the following addresses:"

ffmpeg should handle SDP and RTP streams just fine. Use those given
addresses as input to ffmpeg and see what happens. (One address is
probably: http://10.10.1.23/stream.sdp )

Let us know how it goes.

[FFmpeg-user] FFMPEG to Tangberg video conferencing

[Davood Falahati]

Dear Community,

It occurred to me that I have a Tangberg video conferencing device and I
want to connect to it with ffmpeg. All I know is it invokes h,323 on port
1720. Please tell me how.

You need to be more specific, or fetch more information from the
documentation. How would users *not* using ffmpeg access the device?

Possibly with something like "http://:1720",
which you could pass as input to ffmpeg. But how are we to know. Did
you happen to mention what the device is exactly called?
