- * GstCameraBin implements #GstPhotography interface, which can be used to set
- * and get different settings related to digital imaging. Since currently many
- * of these settings require low-level support the photography interface support
- * is dependent on video src element. In practice photography interface settings
- * cannot be used successfully until in PAUSED state when the video src has
- * opened the video device. However it is possible to configure photography
- * settings in NULL state and camerabin will try applying them later.
