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 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 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.
