[GnomeMeeting-list] Color format

[=?big5?q?yumi=20maiko?= <maikoyumi yahoo com hk>]

Hi,
   I am using "BT878(Lifeview FlyVideo 98EZ )" and
"Logitech USB Camera". When the data are captured from
camera to the video buffer. does anyone know what
color format are these two camera used? RGB24 or
RGB32? I see that the video_buffer size is 3 times the
framesize,it is clearly that it stores RGB data for
each pixel. 
   The second question is that, in gnomemeeting, the
displayed image data uses YUV420P color format. What
color format is changed to YUV420P?

Regards,
wah
