Make sure that FFmpeg knows where to find ZLIB library. ZLIB is needed by the PNG decoder.
ZLIB had to be patched to be used during FFmpeg build on Windows. Note that the patch comes from the ZLIB port of Vcpkg.
Describe the reason for the change.
PNG movies were not able to be decoded because PNG decoder in FFmpeg was disabled due to missing ZLIB library during the build of FFmpeg.
Since ZLIB is installed by default on MacOS and Linux, it wasn't a problem on those systems. But it means that the wrong ZLIB was used by FFmpeg (not the one compiled by OpenRV).
Describe what you have tested and on which operating system.
