Hi,
i currently have a problem loading/unloading the avfilter-7.dll from
ffmpeg 4.22 (x86) using Delphi 2007 (also with Delphi XE3..same problem)
Each loading / unloading process of the library causes a handles leak (of
type semaphores) in Windows x64 Pro for which I currently have no
explanation or solution. I have already tried to upgrade to a newer
version of the DLL but the leak is even worse, strangely, a very old
version (avfilter-2.dll and avfilter-6.dll) is not affected by this
{{{
dllLHandle :=
LoadLibrary(PAnsiChar('c:\Windows\SysWow64\AVFilter-7.dll'));
if dllLHandle<>0 then begin
FreeLibrary(dllLHandle);
dllLHandle:= 0;
end;
}}}
The code above causes an additional leak with each call
Is there something wrong, have I forgotten something?
