x265 will build 32bit on x64
Hi
I used this command ./cross_compile_ffmpeg.sh --disable-nonfree=n --prefer-stable=n and chose 3. Win64 (64-bit only)
The build process completed without error, but the CLI shows that the built x265 (x265.exe and libx265 of ffmpeg) is 32 bit.

Both executables were copied from ffmpeg-windows-build-helpers \ sandbox \ win64, so I don't think I chose 32 bit ...
If I change to --prefer-stable=y ,then build 64 bit correctly. (bit old revision)
WSL2+Ubuntu 20.04 issue?
That's odd, as far as I'm aware the 64 bit gcc can't "use" 32 bit libraries...the noasm is also a bit disconcerting...are you sure you're copying it from the right place?

I've tried several times, it's copying correctly from the win64 folder ...
Of course, I'd deleted directories with rm -r /ffmpeg-windows-build-helpers/ before build (also rm -r ./sandbox/)
my original post, the ffmpeg configuration : --arch=x86_64 Does this mean ffmpeg built on 64 bit?
I tried some builds with --x265-git-checkout-version=
https://bitbucket.org/multicoreware/x265_git/commits/1e8acbf7199241034405aafabb5247c4e3e6e8d0 Up to this commit, it was built correctly in 64 bit.

Hi,
Can anyone confirm that WSL2 Ubuntu support decklink video input ?

It worked the last time I checked and all was built.
I think I found something related.
While this script requires yasm 1.2 and no min nasm version, right now looks like master branch of x265 wants yasm 1.3+ and nasm v2.13+ to be able to use cpu capabilities.
I see this wine ./sandbox/cross_compilers/mingw-w64-x86_64/x86_64-w64-mingw32/bin/x265.exe -h | head x265 [info]: build info [Windows][GCC 10.2.0][64 bit] 8bit+10bit+12bit That's not on WSL though, do you see that? Thanks!

Minutes ago I cloned a the clean repo.
Then used this to compile [in native Kubuntu Linux 21.10]:
$ nice ./cross_compile_ffmpeg.sh --gcc-cpu-count=8 --enable-gpl=y --disable-nonfree=n --build-intel-qsv=y --compiler-flavors=win64 --build-dependencies=y --git-get-latest=y --prefer-stable=n
Then I took the binaries and went to a real Windows machine.
Issue (32bit noasm) still persist in x265.exe [in native Windows 10]:

As a side note, I've been able to compile x265 in linux (for linux) from its current source (videolan, not multicoreware) and it compiled nicely 64-bit and assembly cpu capabilities.
Yeah that's really weird. Mine says

Seems it's still a 64 bit executable: $ file x265.exe: PE32+ executable (console) x86-64, for MS Windows I tried a few things and couldn't fix it, maybe we should file a bug with the x265 people or see if they know anything about it? Thanks!

I understand there's been a fix in x265 to correct this. Its code was incorrectly detecting the target host upon compilation.
i have the same issue as it seems as i wondered why it is that slow. It is not using any CPU feature at all. See
https://superuser.com/questions/1707063/same-ffmpeg-preset-got-way-slower-in-x265-compared-to-a-year-ago-why
bare GIT checkout and ./cross_compile_ffmpeg.sh --git-get-latest=y --disable-nonfree=n --compiler-flavors=win64 --sandbox-ok=y --gcc-cpu-count=4 --prefer-stable=n
still converting without CPU features on my workstation while other builds from external like here do https://github.com/AnimMouse/ffmpeg-autobuild
Did a fresh build;
./cross_compile_ffmpeg.sh --gcc-cpu-count=8 --enable-gpl=y --disable-nonfree=n --build-intel-qsv=y --compiler-flavors=win64 --cflags='-march=skylake -O3' --build-dependencies=y --git-get-latest=y --prefer-stable=n
I pinged the libx265 group on it, no response yet...
