答案

  • Following WHCR to fixed this issue.  but the test result is failed.

    search : System.Client.Webcam.PhysicalLocation --> see Page 98 ~ 101

    Description:
    For any camera device that is built into the chassis of the system and has mechanically fixed
    direction, the firmware must provide the _PLD method and set the panel field (bits[69:67]) to the
    appropriate value for the panel on which the camera is mounted. For example, "Front" indicates the
    camera view the user (webcam), while "Back" indicates that the camera views away from the end
    user (still or video camera).
    In addition, bit 143:128 (Vertical Offset), and bits 159:144 (Horizontal Offset) must provide the
    relative location of the camera with respect to the display. This origin is relative to the native pixel
    addressing in the display component and should match the present display orientation of landscape
    or portrait. The origin is the lower left hand corner of the display, where positive Horizontal and
    Vertical Offset values are to the right and up, respectively.
