Re: [GnomeMeeting-list] experience with the V4L1 compatibility of V4L2

[Damien Sandras <dsandras seconix com>]

Hi,


Bad news, I only had problem reports for the winnov videum. But nobody was
able to debug it.

Try to know which palette is supported by the driver, and we can "force"
this palette for your card in pwlib.

When a palette is selected, and that it fails, it tries the following palette.
But what I don't understand, is that apparently it is only receiving
partial palette names instead of full ones.
