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
