Attention: A block ID of value UINT64_MAX indicates that the Block ID is invalid and must not be used.
GigE Camera Devices
If the Extended ID mode is disabled (default), the sequence number starts with 1 and wraps at 65535. If the Extended ID mode is enabled, the sequence number starts with 1 and uses the full 64-bit unsigned integer value range.
USB Camera Devices
The sequence number starts with 0 and uses the full 64 Bit range.
The block ID of the grabbed frame (camera device specific).
A value of 0 indicates that this feature is not supported by the camera. You can configure the Extended ID mode by setting the GevGVSPExtendedIDMode or the BslGevGVSPExtendedIDMode parameter, if available. The Instant Camera class and the pylon GigE stream grabber provide additional parameters for controlling the Extended ID mode.
