[ffmpeg] Build error on x64-windows-static

[baiyfcu]

The files msys2-gawk-5-01baeb86.3.1-1-x86_64.pkg.tar.zst and msys2-gzip-1.13-1-x86_64.pkg.tar.zst show some file sizes as 0 when opened on Windows ARM, causing issues with extraction. After re-packaging these two files, they can be extracted correctly.

In the compressed file msys2-gawk-5-01baeb86.3.1-1-x86_64.pkg.tar.zst, the problematic file is usr\bin\gawk.exe. In the file msys2-gzip-1.13-1-x86_64.pkg.tar.zst, the problematic file is usr\bin\gunzip.

I guess the 0 KB files are symlinks. Not sure how it is actually implemented, but I guess they could be extracted as pure copies.

I can't reproduce this issue locally.

It might be related to this.

Let me confirm if this issue has been tested in a Windows ARM environment on your side.

When installing libiconv:x64-windows-static with vcpkg, it shows an error similar to this.

Currently, the issue can be resolved by extracting the files using the above command, then re-compressing them. After that, replace the file in the vcpkg downloads directory with the newly compressed file and modify the SHA256 string on line 313 of the scripts/cmake/vcpkg_acquire_msys.cmake file.

On Windows, when I copied the user directory and compressed the newly copied user directory, after compression, it worked normally. However, there were some extra files in the compressed archive.

For cmake -E tar ..., another issue shows a problem with locales vs. Unicode: #43176. The suggested mitigation was to "change system locale to en-US." Would this make a difference here?

[baiyfcu]

After changing the system locale, it seems to be working. However, I found an issue when using the built-in tar -xvf msys2-binutils-2.43.1-1-x86_64.pkg.tar.zst, as it reports an error.

Does vcpkg use that "built-in tar"?

[baiyfcu]

To prevent any modified cache, I pulled the latest code from the vcpkg repository again, but the issue still persists.

Using the built-in Windows tar tool to extract and then re-compress and replace the files can resolve the issue.
Although there is an error message during extraction, it can be ignored and does not affect usage.
