Important Please do support Ukraine!

GitHub response to the war in Ukraine
GitHub as a company is also donating $100,000 to Razom and matching an additional $200,000 of donations from employees to help support relief efforts in the region.

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#.

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.

• on Windows:
  Native ffmpeg libraries are pre bundled in this repository, please note the are GPL(!) libraries. The x64 libraries source from CODEX FFMPEG. Please check to example project it shows how specify path to libraries.

• on OS X:
  Install ffmpeg via Homebrew:

brew install ffmpeg

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

• on Linux:
  Use your package manager of choice. Normally you need to set static ffmpeg.RootPath = with full path to FFmpeg libraries.

Generation

The bindings generator uses CppSharp.

Prerequisites:

• As of time of writing, FFmpeg 5.1 is supported, whilst FFmpeg 6.0 is not. Versions older or inbetween may or may not be supported. Check and contribute to the table below to keep track of the version used.
• Visual Studio 2022 with C# and C++ desktop development workloads and Windows SDK for desktop. Older Visual Studio versions are not supported in the master branch and require minor modification of the project file to do so.

Steps to generate:

• Set the Active Solution plattform to a specific plattform and not AnyCPU. Eg. x64 or x86
  • Just for clarification: Only FFmpeg.AutoGen.CppSharpUnsafeGenerator needs to run in a specific architecutre. The bindings may be used in your project as as AnyCPU or another architecture. However, the bindings won't be valid, even if paired with a .dll of the correct plattform. Bindings need to be regenerated per plattform and included per-plattform with program logic to switch between them.
• Run FFmpeg.AutoGen.CppSharpUnsafeGenerator;
• All files with extension *.g.cs in FFmpeg.AutoGen project will be regenerated.
