Read and Write to Video Memory RRS feed

  • Question

  • Hi All,

    I need to write a simple app to write and read to a video memory location.  Can anyone suggest a starting point for me?  I am assuming my biggest hurdle will be developing the driver code to this.  Also, which driver example in WDk would assist me to get started?

    Appreciate any and all suggestions,

    OJK

  • Playing aroung IRQ and DMA to read/write directly from/to video memory is a frustrating effort. I suggest work with DirectDraw APIs instead.

  • Hello,

     

    I think your issue should be raised in the Media Foundation Development. I believe they will know more information of this issue than us, and I will move this one to that forum.

     

    Thanks for your understanding,

     

    Best regards,

    Jesse
