RTMP and HLS do different jobs: RTMP is used in some workflows to send an encoded stream to an ingest endpoint, while HLS is an HTTP-based format for delivering live or recorded video to viewers. For most live-video systems, production, ingest, packaging, and playback are separate stages—and the protocol used at one stage does not automatically determine the others.
Where protocols fit in a live-video workflow
A useful way to understand streaming protocols is to follow the video from its source to its audience. A camera or playback source produces media; an encoder prepares it; an ingest service receives it; a server or streaming platform may package it; and a player delivers it to viewers. Different protocols can serve different links in that chain.
- Capture and encode: The source is turned into encoded audio and video. A protocol does not, by itself, perform this encoding.
- Contribution or ingest: The encoded stream travels from a production tool or source to a service. RTMP, SRT, and WHIP can be used in this role, depending on endpoint support and workflow.
- Package and distribute: A service may prepare media for delivery through infrastructure such as a CDN.
- Viewer playback: Adaptive HTTP formats such as HLS and MPEG-DASH deliver media to a player, which can choose among available renditions as network conditions change.
A protocol is not a codec, an encoder, a streaming platform, or a guarantee of end-to-end latency. A service may accept one protocol for ingest and use another for playback. Check both the sending and receiving endpoints before choosing a workflow.
RTMP vs. HLS: what is the difference?
RTMP is best understood here as a contribution or ingest option: a production tool sends an encoded stream to an endpoint that accepts it. HLS is a delivery format: a service makes live or prerecorded media available to players over HTTP. They are therefore not direct substitutes in every workflow.

The CDN Alliance’s workflow paper lists RTMP among protocols used to send encoded streams into CDN or cloud infrastructure. It describes HLS or DASH ingest as possible but rarely used in the practice covered by that paper; this is an industry account, not a universal platform rule. The receiving service determines which ingest methods it accepts. The sources available for this explainer do not establish a current primary RTMP specification or support details for particular platforms, so verify those details with the platform you plan to use.
Apple describes HLS as sending audio and video over HTTP from ordinary web servers and CDN infrastructure. It supports live and prerecorded media, alternate bitrate streams, and playback adaptation to available network conditions. Apple’s HLS authoring recommendations cover matters such as codecs, containers, playlists, and failover, but those are Apple-platform recommendations rather than a universal requirement for every HLS deployment.
How the main streaming protocols compare
| Technology | What it is | Typical role | What to check |
|---|---|---|---|
| RTMP | A real-time messaging and stream transport used in some workflows | Encoder or production tool to an ingest endpoint | Whether the receiver accepts it, codec compatibility, network path, and operational familiarity |
| HLS | An HTTP-based live and on-demand media delivery format | Server or CDN to player | Device and player support, adaptive bitrate renditions, CDN fit, and latency configuration |
| MPEG-DASH | An adaptive HTTP streaming standard | Server or CDN to player | Player and platform support, media format and codec profile, packaging, and latency features |
| SRT | An open-source transport technology | Contribution or distribution across variable networks | Endpoint support, packet-loss recovery, encryption, and configured latency |
| WebRTC | A framework for interactive real-time communication | Browser or app interaction and real-time media paths | Interactivity needs, signaling and connectivity, encryption, and deployment scale |
| WHIP | An HTTP-based protocol for WebRTC ingestion | WebRTC source to a streaming service or CDN | Endpoint support, workflow integration, and whether the playback path should remain interactive |
HLS and MPEG-DASH for viewer delivery
HLS
HLS is designed for HTTP delivery and can use ordinary web servers and CDN infrastructure. A presentation can include alternate bitrate streams so playback can adapt to available bandwidth. Apple’s overview says HLS “dynamically adapts to network conditions by optimizing playback for the available speed of wired and wireless connections.” That describes an adaptive delivery capability, not a guarantee that every implementation will avoid buffering.

Apple also documents Low-Latency HLS, which uses features including partial media segments, playlist delta updates, blocking reloads, preload hints, and rendition reports. Its current authoring specification recommends a one-second Low-Latency HLS part target. That is a part-duration recommendation—not a promise of one-second glass-to-glass latency. Apple further says the target must be at least the maximum round-trip time expected for 95% of clients and should be at least three times that P95 round-trip time.

Apple says clients can fall back to regular-latency playback when the low-latency configuration requirements are not met. A low-latency label alone does not make a complete workflow low-latency.
MPEG-DASH
MPEG describes DASH as a standard for live and on-demand streaming. It has provisions for MPEG-4 and MPEG-2 Transport Streams and can also be used with other media formats. Like HLS, it belongs to adaptive HTTP delivery rather than being a general-purpose contribution protocol.

There is no universal winner between DASH and HLS established here. Compare the actual player and platform support, content formats, packaging setup, and latency features for the audience and infrastructure you have.
SRT for contribution over variable networks
SRT is an open-source transport option intended for streaming across unpredictable networks. Haivision describes the technology in those terms, and the SRT project documentation highlights encryption and packet-loss recovery. The project’s version 1.5.4 protocol text describes a UDP-based, user-level transport with reliability and security mechanisms.
SRT handles transport between endpoints; it does not encode the video or define an adaptive HTTP playback format for viewers. Whether it helps in a particular setup depends on both endpoints supporting it and on how the transport is configured. Its packet-loss recovery and encryption features should not be mistaken for a complete production, packaging, or distribution system.

WebRTC and WHIP for interactive and real-time workflows
WebRTC is built for interactive real-time communication, including media exchanged between browser peers. In RFC 8834, the IETF identifies RTP as required for WebRTC media transport and requires secure RTP profiles; WebRTC endpoints must use SRTP and SRTCP to protect generated RTP and RTCP packets.
WHIP addresses a different link in a workflow: it defines HTTP-based ingestion of WebRTC content into streaming services or CDNs. RFC 9725, published in March 2025, says the protocol can feed conventional media platforms as well as WebRTC end-to-end platforms. WHIP is an ingest path for WebRTC media, not a replacement name for HLS, DASH, or the encoding process.

- Sending an encoded program to a service: Check the service’s ingest options. RTMP remains a familiar contribution option in some workflows; SRT or WHIP may fit where supported and where their respective network or WebRTC workflows are appropriate.
- Delivering live or recorded video to viewers: Compare HLS and MPEG-DASH against your target players, platforms, content packaging, CDN, and latency requirements.
- Enabling interactive, real-time media: Consider WebRTC where the application needs interaction, and check how signaling, connectivity, security, and deployment are handled.
- Crossing an unreliable network: Consider whether SRT is supported at both ends and whether its transport behavior fits the path and latency you can configure.
Before committing, test the complete route: source and encoder, ingest endpoint, any packaging or CDN layer, and the actual viewer player. Receiver compatibility and player behavior matter as much as the protocol’s headline features.
What is the lowest-latency streaming protocol?
There is no defensible universal winner from the evidence available here. WebRTC is designed for interactive real-time communication, while Low-Latency HLS can reduce delay in HTTP delivery when its required backend and client support are in place. SRT’s configured transport latency is another part of a contribution or distribution path, not a glass-to-glass result by itself.
End-to-end delay depends on the whole system: encoder and decoder processing, packaging duration, playlist or signaling behavior, server and CDN support, network path, and player buffering. The cited sources do not provide a controlled, cross-protocol latency benchmark, so do not treat a protocol label or the one-second HLS part target as an end-to-end latency figure.
Keeping a prerecorded YouTube stream live around the clock
If your goal is to loop uploaded recordings as a 24/7 YouTube channel, that is a workflow and operations problem as well as a protocol choice. A DIY setup needs a playback source, an encoder or streaming application, a connection to YouTube’s ingest endpoint, and ongoing power and network access. The protocols above explain how media can move through a system; they do not by themselves keep a computer running or restart a dropped stream.
