LiveMediaStreamer is an open source multimedia framework that allows the manipulation of multiple audio and video streams in real-time in many possible data flow configurations (called scenarios) through a JSON formatted TCP socket APIor by using the middlware RESTfull API. It is designed following a pipeline pattern. It consists in a number of filters that can be concatenated or connected with each other in order to process a desired data flow. Current filters are:

  • Receivers: RTSP, RTP, MPEG-TS and RTMP input protocols.
  • Transmitters: RTSP, RTP, MPEG-TS and MPEG-DASH output protocols.
  • Encoders: H.264, H.265 and VP9 video codecs and AAC, OPUS and G711 audio codecs support.
  • Decoders: Same as encoders.
  • Resamplers: Video resizer or audio resampler.
  • Mixers: Audio or video mixing filters with configurable layouts (PiP, NxM, …) and effects (fade, blend, crop, …).

.. when is it suitable to be used?

LiveMediaStreamer framework offers ease to create specific scenarios, from simple to complex configurations.

Its basic use cases might be:

  • Live streaming: RTP, RTSP, MPEG-TS and MPEG-DASH
  • Ingestion and transcoding: streaming network protocols and codecs translation
  • Live audio and video mixing: real-time configure many audio and video inputs to a desired final layout.
