Re: [GnomeMeeting-list] where does gm find video driver information [FIXED]

[Dennis Gilmore <dennis dgilmore net>]

my camera uses a spca505 bridge  but the driver only puts "SPCA50X USB
Camera" as the description in /proc regardless of the bridge in your
camera. 
the spca501 bridge is the one that only supports 160x120 and 320x240 the
spca508 bridge and the other i.e 505,506 support the required formats.  

i will try and get someone with the 501 bridge to test with no size
defined and see if that works.and report back
