FFmpeg compilation fails on Windows platform

[yuanzhixiang]

Description

I'm trying to build a Rust project using ffmpeg-next on Windows, but the compilation fails during the FFmpeg configuration step. The error occurs when trying to run the FFmpeg configure script.

Environment

Operating System: Windows (version: windows11)
Rust version: rustc 1.79.0 (129f3b996 2024-06-10)
Cargo version: cargo 1.79.0 (ffa9cf99a 2024-06-03)
ffmpeg-next version: 7.0.2
Using Tauri: Yes

Cargo.toml Configuration

[dependencies]
ffmpeg-next = { version = "7.0.2", features = ["build"] }

Error Message

Questions

• Is there a known issue with building FFmpeg on Windows using this configuration?
• Are there any additional steps or configurations needed for Windows builds?

Any help or guidance would be greatly appreciated. Thank you!

先要保证能完成编译源代码中的例子

如果用 x86_64-pc-windows-gnu 编译的话
例如我用的 msys2 安装的 ffmpeg 需要电脑环境变量 添加
FFMPEG_DIR
C:\msys64\mingw64
其它的 类似操作，或者可以直接下载 ffmpeg 官方的 包
需要配置一个关键 项目
这个配置 由于 只在这个 项目中生效 所以 我给项目配置了单独的 config.toml
当前项目文件夹/.cargo/conifg.toml
[env]
BINDGEN_EXTRA_CLANG_ARGS = "--target=x86_64-pc-windows-gnu"

如果 用 x86_64-pc-windows-msvc 不需要上面的配置 但 需要 安装 vcpkg 和 llvm 并配置路径 注意 llvm 需要选择第二个 添加全部 系统变量路径 ，具体 安装过程不在复述。
安装 完成 vcpkg 后 一定要配置 系统环境变量环境
VCPKG_ROOT
...\vcpkg\

上面的都是 默认 编译为 gnu 或者 msvc ，如果 默认 为 gnu 想用 msvc 编译 具体命令为 以 编译 例子 remux 为例 反之亦然。

cargo +stable-x86_64-pc-windows-msvc build --example remux
