[nicker player]

There is a problem, QT needs to rely on PNG JPG webp library, qt itself has these image format plug-ins, and then I use the third party library Leptonic also uses the above similar  but different library,how can I use the same library dependency to reduce the duplication of libraries?[link text](link url)

If you really care about those few bytes you have to re-compile Qt and Leptonic to use these three external libraries.
