Nimble Streamer Live Streaming Capabilities
Nimble Streamer is a powerful and flexible media server that provides a wide range of features for live streaming. The server supports a variety of input protocols including RTMP, RTMPS, SRT, NDI, WebRTC, RIST, RTSP, MPEG-TS, HLS and Icecast. The server can also perform transmuxing, which involves re-packaging content in real-time without changing it, and transcoding, which allows changing the content itself.
The server is highly efficient and has a low resource consumption, making it one of the most efficient streaming servers on the market. Load balancing techniques can be used to create robust delivery networks and spread the load between multiple instances. Nimble Streamer is also used for building secure content delivery networks, with features like hotlink protection, pay-per-view, geo blocking, and encryption.
Nimble Streamer is a versatile and highly efficient streaming server that provides a wide range of features for live streaming, making it a great choice for any content owner, operator or streaming entity looking to deliver high-quality video content.
Nimble Streamer Live Streaming Specifications
The supported input protocols for live streaming in Nimble are as follows:
- RTMP and RTMPS for pulled and published streams
- SRT for Listen, Pull and Rendezvous modes
- NDI via Nimble Live Transcoder
- New: WebRTC WHIP ingest
- RIST for Listen and Pull modes
- RTSP for pulled and announced streams
- MPEG-TS for HTTP and UDP streams
- HLS for pulled streams
- Icecast and SHOUTcast
Hot swap capabilities like Emergency hot swap and Failover hot swap allow switching between source origin and substitute streams with no glitches or artifacts.
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.
The same engine is used for transmuxing into various protocols to avoid processing overhead.
Nimble Streamer Transcoder is a premium add-on that provides advanced filtering capabilities and supports a wide range of input and output codecs, including H.264, H.265/HEVC, VP8, VP9, and more. The server also provides support for a variety of output protocols, including ABR HLS, ABR MPEG-DASH, RTMP, RTMPS, SRT, RIST, RTSP, MPEG-TS, Icecast, and SLDP. Nimble Streamer provides DRM protection and server-side ads insertion through its Advertizer framework.
- Input video content codecs are H.264, H.265/HEVC, VP8, VP9, MPEG2 and MPEG4
- Input audio codec are AAC, MP3, MP2, Opus, Speex and PCM G.711 (a-law, μ-law).
- Output video codecs: H.264 and HEVC
- Output audio codecs: AAC and MP3
- Pass-through of original codecs may also be used
- 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.
The supported output protocols for live streaming are highlighted below:
- ABR HLS with MP4, fragmented MP4 (fMP4), audio-only and MPEG2TS containers
- Apple Low Latency HLS is fully supported by Nimble Streamer for fMP4(CMAF) and audio-only containers
- ABR MPEG-DASH
- Read more about ABR setup for outgoing streams
- HTTP/2 can be used for HLS and MPEG-DASH live output in modern browsers
- SRT for Push (Caller), Listen and Rendezvous modes
- RIST for Push and Listen modes
- RTMP and RTMPS for re-publish and playback
- NDI as Nimble Live Transcoder output
New: Synchronize NDI output with SEI metadata
- SLDP for low latency live playback
- RTSP for playback and re-publish
- MPEG-TS via UDP and TCP, with multiple programs
Take a look at our Get ready for Flash farewell and RTMP decline article about future discontinuity of Flash support by Adobe in 2020. We describe the need to transitioning from RTMP to other technologies for playback purposes and we propose SLDP as an alternative.
- DVR feature set allows recording incoming live streams and provide playback via HLS and MPEG-DASH.
- DVR HLS supports both HEVC (H.265) and AVC (H.264) codecs for fMP4 and MPEG2TS containers simultaneously.
- Server playlist allows creating live streams from VOD files.
- RTMP and RTSP re-publishing allows streaming to edge servers for further transmuxing into protocols required by viewers.
Take a look at example of building delivery network based on RTMP re-publishing from origin to edge.
