[sip-comm-dev] Video Bandwith


#1

Hi,

... for this week, I'm connected to a bandwith constrained and sometimes congested WLAN. It was nice to see, that voice doesn't get easily affected by bandwith congestion (as e.g. in Linphone). But video does.

The picture gets full of artefacts or/and disintegrates when I move.

Experience shows, that with bandwith constraints, a lower spec video actually looks better than a higher one full of artefacts.

While the same applies to all VoIP programs, and Linphone in special, I'd like to ask if SC
- does automatically adapt to network bandwith (it seems to give voice priority which is good)
- can be easyly reconfigured by the user to lower specs for the video (size/frames per second/compression)?

Greetings
Conrad

PS. I could only test SC with SIP and my Asterisk echo.
