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

Hi,
 we can change the hints in the openh323 CVS so that it differentiates
between the spca501 an spca508 cameras.

Anyone will to try different values, and report back?


 /** USB cameras supported by SPCA50X cameras.
 
 */
  { "SPCA501 USB Camera",
    "Intel PC Pro Camera uses the spca50x driver",
    HINT_ONLY_WORKS_PREF_PALETTE        |
    HINT_HAS_PREF_PALETTE,
    VIDEO_PALETTE_RGB24
  },

  { "SPCA508 USB Camera",
    "Intel PC Pro Camera uses the spca50x driver",
    HINT_ONLY_WORKS_PREF_PALETTE         |
     HINT_ALWAYS_WORKS_320_240           |
    HINT_HAS_PREF_PALETTE,
    VIDEO_PALETTE_RGB24
  },



Does this work ????


Derek.
