I was exploring famous OBS Studio source code. That is using one git sub-module at https://github.com/obsproject/libdshowcapture
In the file source/capture-filter.hpp there is a forward declaration of a class which is nowhere defined and used in whole repo and whole OBS-Studio repo.
namespace DShow { // some other declaration // this class is nowhere defined and used class CaptureSource; //some other declaration and definitions }
I checked carefully but did not find any definition nor usage of CaptureSource class. If I am right then what can be purpose of such declaration?
CaptureSource
