- * Set the orientation of the video device. The function only works
- * for video capture device and if the device is currently active (i.e.
- * a video preview has been started or there is a video call using the device).
- * Application can check if a video device is active by calling
- * #pjsua_vid_dev_is_active().
+ * Configure the capability of a video capture device. If the device is 
+ * currently active (i.e. if there is a video call using the device or
+ * a video preview has been started), the function will forward the setting
+ * to the video device instance to be applied immediately, if it supports it.
+ *
+ * The setting will be saved for future opening of the video device, if the 
+ * "keep" argument is set to non-zero. If the video device is currently
+ * inactive, and the "keep" argument is false, this function will return
+ * error.
+ *
+ * Note: This function will only works for video capture devices. To
+ * configure the setting of video renderer device instances, use
+ * pjsua_vid_win API instead.
+ *
+ * Warning: If application refreshes the video device list, it needs to
+ * manually update the settings to reflect the newly updated video device
+ * indexes. See #pjmedia_vid_dev_refresh() for more information.
+ *
+ * See also #pjmedia_vid_stream_set_cap() for more information about setting
