tsMuxeR was created by Roman Vasilenko (a.k.a. physic @ the Doom9 forum). The author gave its source-code to justdan96 [github-dot-com/justdan96]. This repository is not a fork. It doesn't include tsMuxerR's GUI. In this repository I included both zlib and freetype2 besides libmediation. CMake is required for building zlib. I rewrote the muxer's makefile so that the users of MSYS2 don't have to "install" zlib, freetype2 and ninja without a very-good reason.
KNOWN ISSUES:
The 32-bit executable cannot create functional Blu-Ray .ISOs. The previous GUI (v2.6.12) works normally with the 64-bit muxer, as long as the muxer is not compressed with UPX. Stripping the .EXE with "--strip-unneeded" is okay.
