Rust wrapper for FFmpeg libraries

Crates.io MIT licensed Build Status

This library provides a Rust interface for FFmpeg libraries. Rather than supporting all FFmpeg features, we focus on safety and simplicity of the interface.

Supported features

  • Demuxing any self-contained media container
  • Muxing any self-contained media container
  • Setting metadata
  • Seeking
  • Decoding audio and video
  • Encoding audio and video
  • Video frame scaling and pixel format transformations
  • Audio resampling
  • Bitstream filters

Requirements

  • FFmpeg v4.x or v5.x libraries. The following libraries are required:
    • libavutil
    • libavcodec
    • libavformat
    • libswresample
    • libswscale

Compilation

The following env. variables can be used to set correct paths to FFmpeg header files and libraries:

  • FFMPEG_INCLUDE_DIR - path to the FFmpeg header files
  • FFMPEG_LIB_DIR - path to the FFmpeg libs

If you require building for multiple platforms, you can append _PLATFORM_TARGET_TRIPLET to both of the above to create platform specific env. variables, for example:

  • FFMPEG_INCLUDE_DIR_AARCH64_LINUX_ANDROID = ${jniInclude}/arm64-v8a/
  • FFMPEG_LIB_DIR_AARCH64_LINUX_ANDROID = ${jniLibs}/arm64-v8a/
  • FFMPEG_INCLUDE_DIR_X86_64_LINUX_ANDROID = ${jniInclude}/x86_64/
  • FFMPEG_LIB_DIR_X86_64_LINUX_ANDROID = ${jniLibs}/x86_64/

If you prefer static linking, you can force it using:

  • FFMPEG_STATIC=1

License

Even though this library is distributed under the MIT license, the FFmpeg project has its own license policies that need to be respected. See https://ffmpeg.org/legal.html for more details.
