nobody has any idea how to compile the gstreamer libs or use the existing ones?

When I use the MSVC version of gstreamer I get: [ilink64 Error] Fatal: Invalid object file '/0'

Here's the whole project: test2.zip

when I use the mingw version of gstreamer I see ilink64 command line c:\program files (x86)\embarcadero\studio\21.0\bin\ilink64.exe -G8 -L.\Win64\Debug;"c:\program files (x86)\embarcadero\studio\21.0\lib\Win64\debug"; "c:\program files (x86)\embarcadero\studio\21.0\lib\win64\release";"c:\program files (x86)\embarcadero\studio\21.0\lib\win64\release\psdk"; C:\Users\Public\Documents\Embarcadero\Studio\21.0\Dcp\Win64;C:\gstreamer\1.0\mingw_x86_64\lib;"C:\gstreamer\1.0\mingw_x86_64\lib\gstreamer-1.0"; C:\Users\Public\Documents\Embarcadero\Studio\21.0\DCP\Win64\Debug;C:\Users\Public\Documents\Embarcadero\Studio\21.0\Dcp\Win64 -j.\Win64\Debug; "c:\program files (x86)\embarcadero\studio\21.0\lib\Win64\debug";"c:\program files (x86)\embarcadero\studio\21.0\lib\win64\release";"c:\program files (x86)\embarcadero\studio\21.0\lib\win64\release\psdk";C:\Users\Public\Documents\Embarcadero\Studio\21.0\Dcp\Win64;C:\gstreamer\1.0\mingw_x86_64\lib; "C:\gstreamer\1.0\mingw_x86_64\lib\gstreamer-1.0";C:\Users\Public\Documents\Embarcadero\Studio\21.0\DCP\Win64\Debug; C:\Users\Public\Documents\Embarcadero\Studio\21.0\Dcp\Win64 -l.\Win64\Debug -v -Gn -GA"C:\Users\DWinsor\AppData\Local\Temp\vfsE889.tmp"="F:\Users\dwinsor\Documents\Embarcadero\Studio\Projects\test2\Unit1.dfm" -aa -V5.0 -Tpe c0w64w rtl.bpi vcl.bpi memmgr.a sysinit.o .\Win64\Debug\Project1.o .\Win64\Debug\Unit1.o , .\Win64\Debug\Project1.exe , .\Win64\Debug\Project1.map , import64.a cp64mti.a , , Project1.res [ilink64 Error] Fatal: Invalid object file 'asnprintf.c.obj'

The 64 bit compiler.

I tried and get errors when linking the .a Thanks Dan
