RTMP Hosting

What is streaming hosting and why do I need it?

Live streaming video involves special communication, beyond regular HTTP requests used in standard sites. Special software is required to run on server side as services for accepting and serving the streaming connections from clients. This is used in addition to web hosting where website files and scripts are hosted. For more details see VideoWhisper application requirements. A relay streaming server is always used by VideoWhisper solutions for reliability, scaling (standard P2P solutions require broadcasters to have server grade connections for similar usage) and also centralized access/interaction control necessary in these projects.

Streaming can be done using multiple protocols:
RTMP - Real Time Messaging Protocol is a protocol for streaming audio, video and data over the Internet, between web based Adobe Flash applications (PC browsers) or other clients and a server. RTMP is supported by multiple encoders like desktop OBS, Wirecast, GoCoder (for iOS/Android) and hardware video publishing devices. As RTMP is supported using Flash plugin in browser, RTMP streams can be delivered to mobile users using HTML5 HLS, MPEG-DASH (after transcoding if necessary).
WebRTC is a free, open project that provides browsers and mobile applications with Real-Time Communications (RTC) capabilities via simple APIs. WebRTC is supported in HTML5 web applications (PC and mobile browsers) for broadcasting and playback of live video. Does not require Flash. Latest VideoWhisper solutions are built to use WebRTC.
RTSP - Real Time Streaming Protocol (RTSP) is a network control protocol designed for use in entertainment and communications systems to control streaming media servers. RTSP is usually used by IP cameras but can also be used by other streaming solutions for accessing and publishing streams. Is not supported directly in browsers or by Flash plugin so delivery to web users is possible only in other formats (and transcoding may be required).

What hosting type and how much streaming bandwidth and do I need?

Streaming Hosting Type : Depends on required features.

  • To add live streaming capabilities to an existing website / host, the WebRTC Host - Streaming Only plans can bring the necessary features (HTML5 WebRTC, HLS & RTMP, RTSP). When using remote streaming services, you will need your current web hosting to include access to latest FFMPEG and codecs for stream snapshots, analysis, transcoding.
  • All features are available with the WebRTC Host - Complete Hosting plans. Includes snapshots & transcoding, archiving, recording, VOD, HTML5 WebRTC, HLS/DASH delivery for mobiles, HTML5 WebRTC, external session control (rtmp, webrtc), re-streaming (including RTSP 24/7 IP cameras).
  • If you just need the remote flash based videochat, conferencing, live streaming functionality you should review the Remote RTMP (Cloud) hosting plans that just provide the rtmp address for streaming and interactions. You get a turnkey functional RTMP address to use remotely, in combination with your existing web host, to configure in Flash based web apps or encoder apps.
  • If you also need web hosting and/or VOD (video on demand) delivery and/or expect big usage spikes but no archiving/recording/transcoding, you should consider Red5 plans and servers that provide great rates for bandwidht.
  • For all features including archiving, recording, transcoding & HTML5 WebRTC, HLS/DASH delivery for mobiles, HTML5 WebRTC, external session control (rtmp, webrtc) and great reliability, you can also check the Wowza SE based legacy plans and dedicated servers.

Streaming Connection and Bandwidth : Depends on streaming bitrate configured, communication logic (streams per user) and users.
Bandwidth usage involves both server connection and network transfer requirements (monthly bandwidth allocation) that need to be available with your provider. |
Connection size limits maximum numbers of simultaneous users depending on streaming bitrate and monthly transfer limits hours of streaming, also depending on quality settings configured.

Connection and bandwidth requirements per user depend on streaming bitrate and number of streams consumed per user.

Streaming Bitrate
Video quality depends on allocated bandwidth per stream and should be adjusted depending on resolution settings.
Higher resolution requires more bandwidth to show a clear picture without much pixelation. More pixels require more bandwidth.
High resolution streams require more bandwidth, from 1Mbps (360p) to 8 Mbps (Full HD) or even more for extreme resolutions like 2K, 4K.
Resolution and bitrate can be configured from settings, as needed, for each project.

Streams per User
numbers of streams consumed per user (that server needs to stream to and from each user) depends on application type and communication logic.
For 1 way broadcasts each user consumes 1 stream. For Live Streaming application broadcaster transmits 1 stream to server and each viewer receives that stream from server.
If there are 2 way private video chat rooms where each user sees 1 other video and transmits 1 video, 2 streams per user will be required.

Bandwidth Estimation Example
Ex. 1. At starter videochat quality (recommended for sites with low connection users), each user with webcam using our applications with default settings, streams a 240p video around 62kb/s (that's around 500kbps because 1 byte = 8 bits).
Multiplied by 3600 seconds in an hour and adding communication required for extra features, sound that means around 0.25Gb/user/video/hour.
While a 1 to many live streaming application will use 1 stream per viewer, a many to many video conferencing that allows in example 1 webcam broadcast and 3 videos to be watched from other users will require 4 streams/user, meaning 1gb/user/hour.

Ex. 2. For high quality video (in example 720p at 5Mbps), that's around 2.3Gb/hour transfer per stream, meaning about 54Gb per day and 1300Gb/month for continuous streaming.
For a 4 hours event watched by 100 users that will demand 500 Mbps connection bitrate and 920 Gb bandwidth transfer.


Recommended Plans

  • For remote videochat, conferencing, live streaming functionality with no other features (no archiving, recording, vod, transcoding) you should review the Remote RTMP (Cloud) hosting plans.
  • For testing & developing, exploring your options during development, we recommend the Wowza Stream Developer plan. It provides multiple options that may be required when developing .
  • For personal sites or private meetings and events with invite only participans (under 50 simultaneous users), the Remote Consultant, Wowza Stream Developer / Startup on Red5 Premium 3 Popular plan can be used.
  • For startup sites where active users are on the site most of the time, ex. 50-100 simultaneous users, Remote Performer, Wowza Stream Startup or Red5 Premium 3-4 plans can be used.
  • For active sites, broadcasting public events to 100-400 simultaneolus users, continuous usage, higher plans are the way to go (Remote, Wowza or Red5).
  • For big projects where you estimate several hundreds or thousands of users, dedicated servers should be setup.
  • For huge projects where you estimate several thousands of simultaneous users, contact us to discuss special multi server load balancing solutions.
Compare RTMP Hosting Types
RTMP is no longer suitable for websites as support was based on older Flash plugins. Major browsers discontinued Flash support in 2020. For web based live streaming, see HTML5 live streaming options, unless you need only RTMP for some other usage or custom app. HTML5 live streaming server services (recommended) are available with the WebRTC Host plans: Complete Hosting (recommended) & Stream Only (when FFmpeg is available on current web host). Latest PaidVideochat & BroadcastLiveVideo solutions implement HTML5 interfaces that can be used instead of older Flash apps, with suitable HTML5 hosting services.

* = WebRTC apps require FFMPEG with video codecs on web host to generate snapshots and stream analysis, transcoding. Also session control is requred.
NR = Not Recommended. Red5 can be used for recording/archiving but often produced skipped frames in our tests.
Plesk = Managed web hosting on VPS is available on Plesk for 10 domains.
CPanel = Managed web hosting with a CPanel account. Higher plans allow multiple domains.
WHM CPanel = Host unlimited domains, cpanel accounts.
HTTPS is required by certain browsers to allow webcam publishing, MPEG DASH or WebRTC.
HTML5 HLS, MPEG DASH, WebRTC are available with Wowza Streaming Engine based hosting.
Advanced features of plans that include both web and rtmp require site to be deployed on that web account (same server).

Host RTMP on your Own Dedicated Server or VPS

A VPS can be used for live video streaming project development and testing but is not recommended at production times.
Dedicated servers are recommended.

Multiple VPS (Virtual Private Servers) share same server with same hardware (disk, cpu, memory, connection).
While resulting performance issues are not visible when serving http pages, frame loss/latency/temporary freezing can occur in live streams on a VPS, depending on how the other VPS on same server use the shared physical resources and temporary lock these.

Choosing RTMP server type, when running your own dedicated server:

RTMP Server Types Recommended For Own Server License
Red5 Open Source Flash Server
