Important

The FFmpeg API is vast and complex and this project exposes it with minimum modifications - support is very limited. Please consider to ask how to questions on stackoverflow.com or in special repository on github.com. The community may be able to offer some assistance but you will largely be on your own. As another option you can search for a solution in C(lang) as with some effort you can convert it to C#. Here repository with C# converted examples: https://github.com/stjeong/ffmpeg_autogen_cs

FFmpeg.AutoGen

FFmpeg auto generated unsafe bindings for C#/.NET and Mono.

Usage

The basic example of the library usage: video decoding, conversion and frame extraction to jpeg is included in FFmpeg.AutoGen.Example project.
For the more sophisticated operations please refer to offical ffmpeg Documentation expecially API section of it. Nuget packages version uses semantic versioning and in sync with MAJOR and MINOR version of FFmpeg as PATCH incremets does not changing API.

Please check the example project, it shows how to specify the path to libraries.

brew install ffmpeg

Normally you need to set static ffmpeg.RootPath = with full path to FFmpeg libraries.

• on Linux:
