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

[Dennis Gilmore <dennis dgilmore net>]

I am trying to get some feedback from the users.  but what i have found
from the code is 

static __u16 spca501_ext_modes[][6] =
{
	/* x , y , Code, Value (6), Value (7), pipe */
	{ 640, 480, 0, 0x94, 0x004A, 1023 },
	{ 320, 240, 0, 0x94, 0x104A, 896 },
	{ 160, 120, 0, 0x94, 0x204A, 384 },
	{ 0, 0, 0, 0, 0 }
};

static __u16 spca50x_ext_modes[][6] =
{
	/* x , y , Code, Value (6), Value (7), pipe */
	{ 352, 288, 1, 0x1a, 0x1a, 1023 }, /* Tested */
#if 0
	{ 320, 240, 2, 0x1c, 0x1d, 896 }, /* Guessed values - if you are brave,
uncomment and play with these !*/
	{ 240, 180, 3, 0x20, 0x20, 640 }, /* Guessed values */
#endif
	{ 176, 144, 4, 0x34, 0x34, 512 }, /* Tested */
	{ 160, 120, 5, 0x40, 0x40, 384 }, /* Tested */
	{ 0, 0, 0, 0, 0 }
};

static __u16 spca508_ext_modes[][6] =
{
  /* In this table, element 3 (clk) controls the
     clock, and gets written to 0x8700.
  */
	/* x , y , Code, clk, n/a,  pipe */
	{ 352, 288, 0, 0x28, 0x00, 1023},
	{ 320, 240, 1, 0x28, 0x00, 1023},
	{ 176, 144, 2, 0x23, 0x00, 1023}, 
	{ 160, 120, 3, 0x23, 0x00, 1023},
	{ 0, 0, 0, 0, 0 }
};

So it seams that one of the chipsets that we support(spca501) does not
use the standard sizes  but uses 320x240 and 160x120  so i want to find
from them if it does indead work i have had feedback from one user that
the spca508 chipset works but i really want to know if the spca501
does.  if not we may need to add in the hint size definitions for it to
work 

or should we just add them to ensure it will work?

Probably we should also change the line"Intel PC Pro Camera uses the
spca50x driver" to read "USB Cameras supported by the spca50x driver" 
just for the generic aspect of it  it currently shows just one of the
cameras supported
