LL-HLS low-latency live RTMP+SRT standard encoder Auto live-to-VOD archive

Oceaniek streams live sports on FastPix Live. AaoNxt uses Live for premiere events. Aadhan publishes vertical news on FastPix Live.

TRUSTED BY PRODUCT TEAMS SHIPPING VIDEO AT SCALE

Why this matters

Three things live streaming usually breaks. FastPix Live is built for them.

Low-latency broadcast on standard HLS.

Low-latency HLS broadcast with standard players and encoders. No exotic stack to ship.

One API for live AND on-demand.

auto_archive: true on stream creation. The replay asset is playback-ready the moment the broadcast ends. Same playback ID convention, same analytics.

Predictable cost for live too.

Encoded minutes, delivered minutes, archive storage. Set a max resolution per stream and per-stream cost stays predictable.

How it works

Three primitives, one API surface.

TL;DR: 3 calls from create to playback

Create the stream

POST /v1/live/streams. Returns the RTMP ingest URL and the LL-HLS playback URL in one response.

Point your encoder

OBS, Wirecast, vMix, FFmpeg, or any hardware encoder. RTMP / RTMPS / SRT all supported.

Viewers watch

LL-HLS playback in any compatible player. Auto-archives to VOD when the stream ends.

Ingest from any standard encoder.

RTMP, RTMPS, SRT supported. Authenticated stream keys. Backup ingest for redundancy.

LL-HLS broadcast live

Standard HLS player support, no exotic plumbing. Sets the player buffer to the minimum that maintains stable playback. DVR and instant live clipping shipped on the same broadcast - cut a VOD asset from the live stream while it's still in progress, jump back through the DVR window to replay any moment.

Live ends, replay is ready.

FastPix automatically packages the broadcast as a VOD asset the moment the stream ends. Same playback flow.

Customers

“Low latency for live sports was non-negotiable. FastPix gave us that plus instant clip-to-publish for highlights on one API. We stopped fighting infrastructure.”

Oceaniek engineering team

Live sports streaming

“Live + replay on the same API meant our small team didn't have to build a second pipeline for the on-demand library. auto_archive: true and we were done.”

Questions developers ask

Live streaming questions, answered.

How low is 'low latency' really?
2 to 3 seconds glass-to-glass on standard LL-HLS. Sub-1 second requires WebRTC, a different product category; FastPix does not currently offer sub-1s WebRTC. For interactive use cases under 1s, talk to us about roadmap.
Can I use my existing encoder?
Yes. RTMP, RTMPS, and SRT are supported. OBS, Wirecast, vMix, FFmpeg, hardware encoders, anything that speaks standard live protocols.
How do I migrate from AWS MediaLive + MediaPackage?
Move ingest, transcoding, packaging, CDN, and replay archive into one FastPix Live API call. Keep your AWS account for downstream workflows if you want. Full AWS migration path.
How does auto-archive work?
Set auto_archive: true on stream creation. The moment the stream ends, FastPix packages the broadcast as a VOD asset using the same playback ID convention. Replay is ready in seconds.
How is FastPix Live different from Cloudflare Stream?
Cloudflare Stream is bundled with the rest of the Cloudflare edge. Choose them if you already run on Cloudflare. FastPix Live ships low latency LL-HLS, mid-event clipping, and auto-archive on one API. FastPix vs Cloudflare Stream.
How is FastPix Live different from AWS Elemental MediaLive?
AWS Elemental MediaLive requires you to also wire MediaPackage, MediaTailor, MediaStore, MediaConnect. FastPix Live is one API for ingest, transcoding, packaging, delivery, and replay. FastPix vs AWS.
Can I clip live content as it happens?
Yes. Mid-event clipping is available during the live stream, and the Clipping Agent can produce highlight clips automatically from the replay asset.
What is the max concurrent streams I can run?
Plan-based. Free trial pathway supports a small number of concurrent live streams; paid tiers scale up. See pricing.
How do I add live to a React or Next.js app?
Create the stream via the API, embed the FastPix Player with the live playback ID. Player handles LL-HLS, captions, and DRM.
How do I monitor live stream quality?
FastPix Video Data tracks every live session: connect rate, rebuffer ratio, viewer drop-off, regional spread. Real-time dashboard during live, full session log post-event.
What about CTV apps for live sports?
CTV apps (LG, Samsung, Roku) play LL-HLS via the FastPix player. Smart TV cert queue applies to native apps; web-player playback on Tizen and webOS is shipping today.
Can I run a 24/7 channel via Live + Cloud Playout?
Yes. Cloud Playout takes scheduled VOD assets plus live segments and produces a continuous channel with SCTE-35 markers for FAST distribution.
