DirectShow Filter usage with GraphEdit / GraphStudioNext

All Live Video Encoder components are available as DirectShow filters and may be used within DirectShow applications.

We recommend using GraphStudio as a replacement for GraphEdit, as RTMP URLs may be set easily with this software.


Setting DirectShow properties from C++

The H.264 parameters may be set by calling the InanoCodecOpts interface. The RTMP output path may be set by calling the SetFileName() method of the default DirectShow FileSinkFilter interface.
