x264 + ffms2

[naoto89]

Does anybody know how to generate shared ffms2 libs on Windows for compile with x264? I can't find guides about it and seems that it's not very common. I don't understand what I should do after to enter INSTALL from ffms2.

you might want to look at the scripts MBAS (https://github.com/m-ab-s/media-autobuild_suite/) uses,...

[naoto89]

Sorry, but the bad experiences I had with MABS trying to compile FFmpeg with fdk_aac make me avoid it. Even FWBH has not given me so many problems.

[Selur]

Just thought the build script they used might help with your problem.

In any case, now I have one more problem with ffms2. If I try to add prefix using a custom directory, it shows this.

./configure --prefix=tmpbuild --host=i686-pc-mingw32 --enable-shared
configure: error: expected an absolute directory name for --prefix: tmpbuild

I read the help but I get confused and it doesn't seem to say how to reinterpret this on Windows and msys64-mingw.

[Selur]

Assuming you are in some sort of build environment where you can navigate, changing into the tmpbuild folder and calling 'realpath .' should output the absolute path of the folder.

Even if I put --prefix=/c/sandbox/ffms2/tmpbuild I don't see any file being generated inside that folder, it ignored anyway

[Selur]

'configure' shouldn't create anything in that folder.
'make' probably should, if the MakeFile doesn't use the prefix variable you probably don't need it.

[naoto89]

When I try to compile ffms2 and run make I get this error

"No target specified and no makefile found"

Also, there is only two files: makefaile.am y makefile.in.

OK, chancing my luck on an old thread ...

I would like to cross-compile ffms2.dll (ubuntu mingw64, target win11x64) but the instructions aren't all that clear for an old codger.

Suggestions would be welcome.

fyi, here is the .json used by a version of deadsix27's cross-compile build system which successfully builds ffmsindex.exe ... but that isn't ffms2.dll
(the cross-compile build system cross-compiles ffmpeg fine).

Since you are targeting Windows, be aware that some variations of the ffms2 library require building with VC++.
