Consider using deadsix27's at https://github.com/DeadSix27/python_cross_compile_script ... although that has ceased active maintenance.

Or, preferably use MABS https://github.com/m-ab-s/media-autobuild_suite
... update: MABS works really well under Windows Sandbox and doesn't leave stuff on your PC - you can copy results from the Sandbox to your PC before closing the sandbox.
... perhaps see m-ab-s/media-autobuild_suite#2227 for draft-only sample .wsb and whatnot

Or, use rdp's lovely build system https://github.com/rdp/ffmpeg-windows-build-helpers

A Linux to Windows x64 cross-compile script to build ffmpeg with dependencies

i.e. NVidia's NVENC encoder, OpenCL filters, and Vapoursynth input

NOTE: You may attempt to build everything wherever possible with safety settings

          -O3  -fstack-protector-all  -D_FORTIFY_SOURCE=2

This script attempts to build (eveything 64 bit) ffmpeg, primarily in order to utilise eg NVidia's NVENC encoder, optionally some OpenCL filters, and optional Vapoursynth input.

ffmpeg.exe (64-bit, static) with and Vapoursynth input and OpenCL (eg to use with nvidia) and multibit h264/h265
ffprobe.exe (64-bit, static)
mediainfo.exe (64-bit, static)
x264.exe (multibit) with extra input/output media container types eg mpg (64-bit, static)
x265.exe (multibit) (64-bit, static)
mp4box.exe (64-bit, static)
vpx encoder/decoder (64-bit, static)
aom-av1 encoder/decoder (64-bit, static)
dav1d av1 video decoder (64-bit, static)
sox audio processor (64-bit, static)
fftw*.dll 3.3.8 (64-bit)
libaacs.dll (64-bit)(with its libgcrypt*.dll and libgpg_error.dll) (never tried to run it though)

How to build ?

Probably fork your own https://github.com/hydra3333/h3333_python_cross_compile_script_v100.git and then change a small number of things in .py files to point to your fork
Create an Ubuntu VM (tested with 22.04+)
login into ubuntu and start a Terminal window

sudo apt -y install git
cd ~/Desktop
sudo chmod +777 -R ./*
sudo rm -vfR ./h3333_python_cross_compile_script_v100
git clone https://github.com/hydra3333/h3333_python_cross_compile_script_v100.git # or your fork
cp -fv ./h3333_python_cross_compile_script_v100/*.sh ./
sudo chmod +777 -R ./*
./h3333_v100.setup.sh # (once-off, before the first build)

then to build just ffmpeg:
3. ./h3333_v100.003_ff.sh
or to build everything:
4. ./h3333_v100.003.sh
5. To create your own new static libOpenCL.a wrapper after a new nvidia driver with OpenCL.dll is installed on a Win10x64 PC, and a new libvulkan-1.a wrapper after microsoft updates install a new vulkan dll, so you can upload these into in your own fork, please see:
https://github.com/hydra3333/h3333_python_cross_compile_script_v100/tree/master/sources
since this method is used here, rather than building those OpenCL and vulkan_loader from source.
NOTE: we do it this way because khronos frequently updated stuff which then frequently broke building ffmpeg; Nvidia and Microsoft keep these updated reasonably frequently.

Good luck.
