A live streaming server receives video from a broadcaster such as OBS and makes it available for viewers to watch. Hosting one means choosing either a managed streaming service or server software you operate yourself, then configuring two separate paths: ingest from broadcaster to server and playback from server to viewers. A successful OBS connection proves the first path works; it does not by itself configure a viewer-facing player, HTTPS, scaling, recording, or access controls.
What a live streaming server does
In a typical setup, OBS captures and composes the camera, microphone, game, or other sources, encodes the video, and sends it to an ingest endpoint. The server may relay or transcode the incoming feed, package it into formats for playback, and serve a player or playback URL. A content delivery network (CDN) may also be part of the delivery path.
Keep the two sides distinct:
- Ingest: the broadcaster sends the encoded stream to the server or managed service.
- Playback and delivery: the server or CDN makes the stream available to viewers through a player or playback URL.
For example, the Owncast developer documentation describes an FFmpeg-to-HLS playback pipeline. AWS’s reference architecture describes packaged playback using HLS, DASH, and CMAF. These are examples, not evidence that every server uses the same end-to-end protocol. Owncast’s video-pipeline documentation; AWS Live Streaming on AWS Implementation Guide.
Choose managed hosting or software you operate
| Approach | What it provides | What you still need to consider |
|---|---|---|
| Managed streaming service, such as Amazon IVS | A channel with assigned ingest details, a secret stream key, and a playback URL; OBS or supported software can send the stream. | Compare supported protocols, latency needs, player integration, service constraints, and current usage charges. The documentation cited here does not establish a current price comparison. |
| Integrated self-hosted server, such as Owncast | A deployable service with a web interface, RTMP ingest, and an integrated broadcast/viewer workflow. | You operate installation, public network reachability, credentials, upgrades, uptime, and bandwidth or delivery capacity. |
| Streaming server software, such as Ant Media Server or NGINX with its RTMP module | More choice over protocols and architecture. NGINX’s documented module supports RTMP, HLS, and DASH; Ant Media’s quick start describes SSL, a web panel, and WebRTC publishing and playback. | Configuration responsibility is higher. An RTMP module alone is not a complete end-user streaming platform; check ingest, packaging, playback, SSL, scaling, and support. |
When comparing options, check who patches the server, supported ingest and playback protocols, latency and device/player support, whether transcoding or adaptive-bitrate packaging is needed, audience and egress capacity, access control, recording and moderation requirements, observability, support, and total operating cost. There is no universal server size, audience ceiling, latency figure, or cost established by the cited documentation.

For a managed example, AWS’s Amazon IVS channel guide explains channel setup and its ingest and playback details. For self-hosting, Owncast’s installation guide covers installation routes, while Ant Media’s quick start describes a separate server workflow. Use each product’s current production documentation for deployment and hardening rather than treating an introductory guide as a complete production checklist.
How to set up a self-hosted streaming server
The following is a deployment sequence, not a universal install command: the exact steps and requirements depend on the software you select. Owncast offers quick-installer, manual-release, container, and hosting-provider routes. Its documentation cautions against running an uninspected remote installer as root.

- Choose the server and hosting model. Select an integrated service such as Owncast or a more configurable server stack, and provision a supported host with public network reachability. Size it for the actual software, encoding or transcoding workload, and delivery design; the referenced guides do not support one general-purpose server-size recommendation.
- Install from the selected product’s current guide. Follow the route that matches your host and review its deployment requirements. For an introductory Owncast path, start with the installation guide and, if using a manual deployment, its manual install instructions. For Ant Media, use the quick start for the documented initial setup.
- Set up the domain, HTTPS, and firewall. Configure the web-facing service and SSL as appropriate for your software, then expose only the ports the selected implementation requires. Owncast’s manual guide lists TCP 8080 for its web interface and TCP 1935 for RTMP ingest as defaults; these are Owncast defaults, not universal streaming ports. Owncast’s proxy guide explains HTTPS and notes that OBS RTMP ingest goes to Owncast rather than through the HTTP proxy. See Owncast’s SSL and HTTP proxy guidance and its manual setup guide.
- Apply the correct network rules for the chosen service. For Amazon IVS low-latency service, AWS lists RTMPS TCP 443, RTMP TCP 1935, SRT TCP 9000, and WebRTC TCP 4443 plus UDP 32768–61000. These are IVS-specific network requirements, not a port list to copy to an Owncast or other host. Check the current Amazon IVS network requirements for the service and protocol you actually use.
- Secure the admin account and stream key. Set a unique, strong admin password and stream key; replace any defaults or examples. Treat the key as a password: AWS warns that anyone with an IVS channel stream key can stream to that channel. Use RTMPS where supported and appropriate, secure the web interface with SSL, and rotate any key that has been exposed. See AWS’s channel guidance and Owncast’s SSL guidance.
- Point OBS at the ingest endpoint. In OBS, choose the relevant service or custom streaming server, enter the assigned server URL and stream key, and configure output settings compatible with your server or service. Owncast uses the
/live/path and a stream key; its default ingest port is TCP 1935. Ant Media’s sample custom RTMP URL isrtmp://<SERVER_IP_OR_DOMAIN_NAME>/live; its guide says this example assumes security options are not enabled. AWS recommends a two-second keyframe interval for its documented low-latency OBS path. That interval is AWS-specific guidance, not a universal setting for every server. See Owncast’s broadcasting setup, Ant Media’s OBS guide, and AWS’s streaming software setup. - Verify playback separately from ingest. Start the broadcast, confirm that OBS reports a connection and the server shows the stream as live, then open the viewer-facing player or playback URL from a separate browser or device. Test from a network representative of your audience, including HTTPS and embedded playback if you use them. Ant Media’s guide says to confirm the stream as “Broadcasting” in its web panel; Owncast documents a browser interface and admin area.
- Plan to operate it continuously. Decide how you will check logs and health, apply updates, back up configuration, rotate keys, handle recording, monitor capacity and delivery bandwidth, and recover from disconnects. Limits vary by product: AWS documents a 48-hour maximum stream duration and a 30-second no-data disconnect window for Amazon IVS; confirm the current IVS documentation before relying on those service-specific limits.
Protocols: contribution is not playback
RTMP is used for contribution in the Owncast and Ant Media examples. Amazon IVS also documents RTMPS and SRT options. The playback format may differ: AWS’s reference architecture describes HLS, DASH, and CMAF packaging. Configure the broadcaster for the server’s ingest protocol and separately make sure the viewer player supports the playback route you provide. Do not assume that opening an RTMP port alone gives viewers a working player.
Troubleshoot the common failures
OBS cannot connect
- Check the hostname or IP address, port, endpoint path, and stream key for typos.
- Confirm the firewall or cloud security group allows the selected protocol and port.
- Check that the URL scheme matches the service: for example, RTMP versus RTMPS. AWS notes that OBS needs a version that supports RTMPS when RTMPS is selected.
- Verify that the endpoint and key belong together and have not been rotated or revoked.
For service-specific connection requirements, consult AWS’s OBS setup and Owncast’s port and setup notes.

OBS connects, but viewers see no stream
- Check whether the server reports the broadcast as live.
- Test the playback URL and player independently; ingest success and viewer delivery are separate stages.
- Review proxy and HTTPS configuration, including whether the player points to the correct host and playback path.
- Check that the selected player supports the server’s playback format.
Viewers buffer or cannot reach playback
- Check encoding compatibility, available network throughput and egress, firewall rules, and any CDN path.
- Determine whether your architecture needs transcoding or adaptive-bitrate renditions for the expected devices and network conditions.
- Do not assume that lowering the ingest bitrate alone fixes a delivery-capacity, packaging, or player problem.
There is no exact concurrent-viewer ceiling supported by the cited material. Establish capacity for the selected software, hardware, bitrate, transcoding load, and delivery design rather than relying on a generic number.
