Hi, for whts here
https://github.com/phulshof/RetroFE/tree/13f1b7aaab37b34f6cce732166fd7e6e0d002df9Was gstreamer 1.4.0.
On windows I install version 1.18.3, copy folder, then unistall and nstalled 1.18.6, copy folder same to 1.20. Then wen want to compile just rename the version I want to the default folder gstreamer name. Then I made checked 1.18.3 dlls and made a backup of tht dlls for versions 1.18.6 and 1.20. So wen I was testing if I compile with version 1.20 e copy to core all dlls from bin folder and gstreamer 1 replacing it for tests.
GStreamer 1.18.3 has issues for compile on win32. They only fixed on 1.18.4 and for some reason in fev2022 they released 1.18.6 stable version. I don't know if on Linux u can make tht trick of change folder names....
