Description Jean-François Fortin Tam 2010-02-07 17:16:07 UTC 
The image in my video calls tests is very blocky and not pretty. It would be nice to have better quality than that. Looking at the network traffic in gnome-system-monitor, it seems to use a bitrate that varies between 5 kbytes/s and 25 kbytes/s (~200 kbits/s). Many high-speed residential connections have roughly 500 kbits/s upload bandwidth in practice (or more), and would benefit from higher bitrates.

I have libtheora 1.1.0 ("thusnelda") installed. Even at 200kbits/s, though I don't know what image resolution it uses, I'd assume it should look better than that...

The current plan is to be smarter and adjust the video quality automatically depending on the disponible bandwith. 
Farsight should gain this feature at some point: https://bugs.freedesktop.org/show_bug.cgi?id=26490
