Low-latency streaming

Low-latency streaming: less waiting, more live.

In an auction, a class or an interactive event, every second counts. Choose the output based on who is watching: WebRTC up to 0.3 s to interact, LL-HLS ~3 s to follow the action closely and HLS for massive audiences.

WebRTC and LL-HLS add on to your paid video plan from USD 20/month per channel.

The protocol depends on who receives your feed.

SRT connects production equipment. WebRTC, LL-HLS and HLS deliver video to viewers.

SRT

The ingest that survives unstable networks.

SRT speeds up the encoder-to-origin leg; the output sets how long your audience waits. That is why you choose both.

The same moment, three different waits.

How long the same moment takes to reach the screen, depending on the output you choose.

Measure it yourself

Measure the real delay, not just the ping.

Film a stopwatch, open it in your player and compare both in the same photo. The difference is your end-to-end latency.

  • Repeat the test on different networks and devices
  • Write down encoder, bitrate, protocol and region
  • Measure your chat or bidding system separately: it travels on another channel

Your live stream with less delay in 4 steps.

  1. Define the interaction

    How much delay your event tolerates and how many people will watch.

  2. Connect your encoder

    Send over RTMP or SRT and match bitrate and keyframes to your connection.

  3. Choose the output

    HLS is included, or add WebRTC or LL-HLS to your channel.

  4. Measure before the event

    Test from your audience regions, with 24/7 support by your side.

Your questions about streaming without delay

Every internet stream has some latency; what you choose is how much. At XtreamCast: WebRTC up to 0.3 s, LL-HLS ~3 s and standard HLS about 30 s, a margin our player keeps on purpose to absorb network drops. On ingest, SRT recovers lost packets without cutting the feed.

SRT speeds up and stabilizes the leg between your encoder and the origin. What your audience sees is set by the output: HLS, LL-HLS or WebRTC.

With our player in the browser, once the add-on is enabled on your channel. Ingest stays RTMP or SRT, and the WebRTC output is delivered through our player, with no WHEP endpoint for third-party players.

HLS, ideally with Global CDN, or LL-HLS if that audience needs to follow the action closely. WebRTC performs best with interactive groups such as bidders or students.

Paid video plans start at USD 25/month with HLS and RTMP and SRT ingest included. WebRTC adds USD 20/month and LL-HLS USD 20/month per channel.

You can start with our free plan, no card required, to validate your encoder, your connection and the player. WebRTC and LL-HLS are add-ons for paid plans: to assess them for your event, talk to an expert.

Choose channel features and capacity

Included in Started+, Pro+ and Max+

RTMP/SRT ingest, HLS output, branded player, up to 10 restream destinations, Recording Cloud, Live Editor Pro and a VOD library. Everything is configured from the panel, within your plan transfer and storage.

Video add-ons

Live Station: USD 10/month per channel. ABR transcoder: USD 20/month. WebRTC: USD 20/month. Global CDN: USD 20/month. They are enabled per channel; on Enterprise+ they are defined in the proposal.

Custom projects

Projects with DRM, SSO, EPG or your own apps: we assess them with an expert. SecureToken, geo-blocking and player domain restriction come with the panel, and the player embeds in the platform where your users sign in.

Started+ begins at USD 25/month with 1 TB of transfer and 5 GB of storage; Pro+ and Max+ go up to 3 and 6 TB. No automatic overage charges: we notify you at 80% and 100% of your transfer and you can add capacity instantly from the panel, prorated. For 24/7 feeds, size with headroom or move to Enterprise+, with transfer from 100 TB/month defined in the contract. Transfer policy (Terms, section X)
