SIPSorceryMedia.FFmpeg

This project is an example of developing a C# library that can use features from FFmpeg native libraries and that inegrates with the SIPSorcery real-time communications library.

This project has been tested successfully on Windows, MacOs and Linux.

The classes in this project provide functions to:

  • Video codecs: VP8, H264
  • Audio codecs: PCMU (G711), PCMA (G711), G722, G729 and Opus
  • Video input:
    • using local file or remote using URI (like this)
    • using camera
    • using screen
  • Audio input:
    • using local file or remote using URI (like this or this)
    • using microphone

You can set any Video input (or none) with any Audio input (or none)

There is no Audio ouput in this library. For this you can use SIPSorcery.SDL2
