Video capture mode
Indicates the video capture mode for capturing screen changes.
There are two methods of capturing screen changes, Driver capture and Polling capture.
- Driver capture uses a low-level video driver to capture the changes to the screen image.
- Polling capture works by periodically scanning the screen image for changes.
Typically, the Driver capture mode provides better performance than the Polling capture mode. However, there are some types of application that cannot be captured by the Driver capture method. Typically these are OpenGL or Direct3D based applications, such as computer aided design applications.
The polling capture mode is capable of capturing screen changes from OpenGL & Direct3D applications.
There are three video capture mode settings for the Remote Control host:
Auto
In this mode, Driver capture is used if it is available. If the video driver cannot be installed for some reason, or the machine resources are too limited to load the driver, Polling capture is used as a fallback.
Driver
Driver capture is used exclusively. There is no fallback to Polling mode if the Driver mode is unavailable.
Polling
Polling mode is used exclusively.
