Live streaming capabilities of Nimble Streamer

Nimble Streamer provides wide feature set for live streaming. This includes both re-packaging content between protocols and transcoding to change the content itself.

Input protocols

The supported input protocols for live streaming are:

Enhanced interleaving compensation can be set up in case when your audio and video are unsynchronized.


By default, Nimble Streamer performs transmuxing of content. This means re-packaging on-the-fly without changing the content. It's taken using one protocol and streamed out via other selected protocols.
Same engine is used for transmuxing into various protocols to avoid processing overhead.


Transcoder for Nimble Streamer allows transforming content before packaging it into required protocols.
It's a premium add-on for Nimble Streamer available per subscription.

  • Input video content codecs areH.264, H.265/HEVC, VP8, VP9, MPEG2 and MPEG4

  • Advanced filtering with FFmpeg filters allows transforming content in various ways. Some examples are changing the video resize, graphic overlays, picture-in-picture, key frames alignments, audio re-sampling etc.
  • Decoding and encoding are done just once to avoid processing overhead.
  • Several advantages over traditional FFmpeg command-line tool.
  • Web UI provides easy-to-use drag-n-drop workflow to apply transcoding scenarios across various servers in a few clicks.
  • Intel® Quick Sync Video hardware and software support.
  • NVidia® NVENC hardware acceleration support - check stress-testing of Tesla M60 GPU to see some benchmarks.
  • NDI is available for input and output.

Transcoder documentation reference has links to all setup and configuration articles.

Output protocols
