OnvifGetSnapshotUri2MediaCommand class
A client uses the GetSnapshotUri command to obtain a JPEG snapshot from the device. The returned URI shall remain valid indefinitely even if the profile is changed. The ValidUntilConnect, ValidUntilReboot and Timeout Parameter shall be set accordingly (ValidUntilConnect=false, ValidUntilReboot=false, timeout=PT0S). The URI can be used for acquiring a JPEG image through a HTTP GET operation. The image encoding will always be JPEG regardless of the encoding setting in the media profile. The Jpeg settings (like resolution or quality) may be taken from the profile if suitable. The provided image will be updated automatically and independent from calls to GetSnapshotUri.
