module unsafe for SAFESEH image C++

Disabling option "Image has Safe Exception Handlers" in Project properties -> Configuration Properties -> Linker -> Advanced tab helped me.

From the comments:

This happens when you link an .obj or .lib that contains code created by an earlier version of the compiler. Which of course would be common if you downloaded a binary for opencv_ffmpeg instead of the source. You can turn the linker option off but then you'll still have a CRT version incompatibility that can byte. Rebuild the library from source. – Hans Passant May 15 at 13:01  
 
Thanks for the help, it worked – Aaron Thompson May 17 at 14:50

If you got this error while building ZLIB in Visual Studio here is the solution. Look for contrib\masmx86\bld_ml32.bat and add /safeseh as a option

Before

ml /coff /Zi /c /Flmatch686.lst match686.asm
ml /coff /Zi /c /Flinffas32.lst inffas32.asm

After

ml /safeseh /coff /Zi /c /Flmatch686.lst match686.asm
ml /safeseh /coff /Zi /c /Flinffas32.lst inffas32.asm

Other way is to add some SEH handler (empty for example) to asm files and compile them with /safeseh option, then compile other code normally with /SAFESEH:YES compiler option.

Empty SEH handler:

.safeseh SEH_handler

SEH_handler   proc
;handler
ret

SEH_handler   endp
