Uncompressed Video

May 26, 2009 at 6:53 PM

Hi,

 

I am attempting to get the driver working with a camera that only supports uncompressed video. I have been able to read the available formats from the camera using this driver successfully. However, when I attempt to get the first stream I get “IOControl call failed Error 31 (0x1F)”. I think that the driver is failing during the negotiation over bandwidth. If anyone has attempted this or has any information that may be helpful it would be appreciated.

 

This is one of the formats that I am trying to read.

 

Format       5

dwWidth      320

dwHeight     240

dwMaxBuff    38400

nNumInterval 1

 

Thanks, Mike

Hi Mike,

 

Sorry to bump this old thread but I was curious if you were able to find a solution? I am having similar problems.

 

Thanks,
