Controlling brightness/contrast video acquisition from a program RRS feed

  • Question

  • Hello,

    I'm writing an application for video capture; I'm looking for a way to control brightness/contrast directly from the program (i.e. not by opening the video control dialog).
    I've tried the DirectShow IVMRMixerControl9/VMR9ProcAmpControl approach but while it works with other cameras it doesn't work with the specific camera I need to use (I'm getting the VFW_E_VMR_NO_PROCAMP_HW error, meaning IIUC the feature is not supported).

    Is there any other way to control acquisition parameters ?
