Refreshes the devices and compressors list.
Declaration
procedure RefreshDevicesAndCompressorsLists;
void __fastcall RefreshDevicesAndCompressorsLists (void)
Sub RefreshDevicesAndCompressorsLists
Description
Used mainly to refresh the VideoCompressors and AudioCompressors list, e.g. after installing/uninstalling video compressors or audio compressors.
Calling this procedure refreshes also the AudioDevices and VideoDevices lists. However usually it is not useful to invoke this procedure for video capture devices or audio capture devices, because when connecting/disconnecting them, the corresponding lists are refreshed automatically and the OnDeviceArrivalOrRemoval event occurs to notify the list have been updated.
