It’s based on .net standard 2.0

  • Watermark.marking a picture watermark during recording.
  • Screenshot.screenshot once or set a timer.

This package is based on FFmpeg v4.3 Resources under ffmpeg_v4.3 are from FFmpeg officical Website.You can download a newer version and replace it in the project.We are using the official shared version of ffmpeg package.

Since Linux has so many different version branches,we don’t support it yet.FFmpeg provides built packages for Debian/Ubuntu/Fedora and Redhat only.For other versions and custom requirements,you can build FFmpeg from its source code.So here we don’t provide linux support. but we will handle it soon.

If you wanna extend Linux support,just edit this place.


We just packaged a library to transfer command to FFmpeg CLI.It’s useful and simiple,except this,you also can use the FFmpeg API to use it for development.FFmpeg SDK only provide for baisc language like C.


Check the sample project to see how to use it easily.
