Rusty FFmpeg

Cross platform FFI bindings for FFmpeg inner libraries. This is a crate that:

1. Linking FFmpeg libraries for you.
2. Generates Rust binding for FFmpeg libraries.

Usage

To use this crate, you need to set several environment variables.

Simplest:

Build ffmpeg staticly and set FFMPEG_PKG_CONFIG_PATH to the path of the generated FFmpeg package-config files. And you don't need to set other environment variables for static linking.

More complex

You need to set environment variable for both linking and generating bindings.

To link:

1. Dynamic linking with prebuilt dylib: Set FFMPEG_DLL_PATH to the path of dll or so. (Windows: Put corresponding .lib file next to the .dll file.)

2. Static linking with prebuilt staticlib: or set FFMPEG_LIB_DIR to the path of the FFmpeg prebuilt libs directory.

To generate bindings:

1. Compile-time binding generation(requires clang dylib): Set FFMPEG_INCLUDE_DIR to the path to the header files for binding generation.

2. Use pre-built binding: Set FFMPEG_BINDING_PATH to the prebuilt binding file.

Attention

FFI is not that easy, especially when you are dealing with a big old C project. Don't feel depressed when there are some problems. The CI check already have some typical use cases, you can check it. File an issue if you still have some problem.
