This list shows all the video sources and source parameter information you added, not all of them are decoded. If decoding to output or for preview, you need to manually drag it to the upper preview or output window for decoding. When the video source is shown as green "Display/Service”, the source is decoding or streaming; the gray "Offline" means it is not used as decoding source; the blue "Connecting” indicates that the source is establishing a connection and is ready to decode; and the Yellow “Reconnecting" indicates that the source is decoding abnormally and tries to connect and decode. The Red “wrong” indicates the source is wrong and can not be decoded.
