Decoder : this field allows change h264-decoder for handle input video stream.
No Decode - use this mode if you don't need NDI or SDI output and plan use only CrossLine or UDP Multicast output.
Software decoder– good choice for bitrate under 10Mbs. It allows correct decode all h264 profiles.
Hardware decoder allows decrease CPU usage but more sensitive to h264 profiles. Use HW decoder for hight speed bitrate for get real profit. Be aware: some HW decoders allow only 1 or 2 decode process in same time (it depends on hardware).
HW: video tools– good choice for macOS user.
HW: dxva2 – Windows way for use HW (uses D3D9 video functionality)
HW: d3d11va – other Windows way for use HW (uses D3D11 video functionality)
