[FFmpeg-devel] Procedure to enable the Windows on ARM64 FFMPEG Libraries

[Niranjan Kshatriya (QUIC)]

Thanks for the Info.

We do have some queries :

> It will be good to have Windows on ARM prebuilt libraries for FFMPEG as part of Download repository (Releases * BtbN/FFmpeg-Builds (github.com)<https://github.com/BtbN/FFmpeg-Builds/releases>).

I decided against it since it's highly experimental still and breaks every other weak for a multitude of reasons.
>>[Niranjan]: Is the Reason of failure is due to toolchain not mature? As toolchain : https://github.com/mstorsjo/llvm-mingw/releases  is not stable we may end compilation error for arm is what you highlighting as multitude of reasons ?

> What it takes to generate Windows on ARM libraries?

Right now builds work fine, just grab my set of scripts and build away.

>>[Niranjan ]: We have learnt from Kacper below 3 ways to compile:
Currently you have 3 ways to produce native Windows on ARM binaries.
Mentioned by Martin, LLVM based toolchain https://github.com/mstorsjo/llvm-mingw/releases
Mentioned by You, GNU based toolchain
https://github.com/Windows-on-ARM-Experiments

Are you following one of above step for compilation?

>>[Niranjan]: As Arm binaries are not compile on server, how the contributor can pick these binaries?
As for prebuilt binaries, it's fully up to contributors to decide to include ARM pipelines in their auto build scripts.

Niranjan
