[Ekiga-devel-list] Experiments in Grey

[Jordi <mumismo gmail com>]

Hi,

I am doing some experiments on video bandwidth, using ekiga and modifying its code a little bit. 

I'd
like to use alternative lower bandwidth video flows. I think a good
idea can be eliminate the colour information by setting the "Grey"
colour format instead of the "YUV420P" format.
I have tried to make a simple gui for this but it if I try to use the "Grey" format I got the following error:
"Error opening video device," "The driver doesn't seem to support any of the color formats supported by Ekiga"

I have taken a look to pwlib and they seem to try any colour
format you give it and if it can not be used they just try using other
colour format. 

There is any reason why Grey format can not be used instead of Ekiga? 
Is it a problem with the webcam? 
Am I doing something wrong?
Any other idea about what can be tweaked to minimize bandwidth usage will be welcome.
