If you want to loop pre-recorded videos on YouTube Live, a cloud playout service can run the playlist without keeping your own computer on. “Custom RTMP encoder” can mean a separate live encoder feeding a managed RTMP service, or it can mean sending a cloud-played video to a custom RTMP destination; those are different workflows.
The first decision is not which service has the longest feature list. It is whether you need to upload finished files for cloud playback, keep producing a live feed in an encoder such as OBS, or do both for separate parts of your operation. The available vendor documentation describes overlapping capabilities, but it does not establish that every service combines them or that one channel needs both.
Two meanings of a cloud YouTube loop workflow
In a file-playout workflow, you upload finished videos to a provider, arrange them in a playlist, connect the destination channel and schedule or start a live broadcast. The provider plays the files in sequence and repeats the playlist if its controls allow it. Your computer is not the source of the ongoing video once the cloud playback is running.
In an encoder-ingest workflow, your computer or another source generates a live feed. An encoder converts and sends that feed to a managed RTMP service, which then passes it on to YouTube or another destination. The source may show a live camera, a rendered scene, a game, an OBS composition, or a playlist that your local software is playing. Here, the encoder remains part of the production path even if a managed service handles delivery onward.
YouTube’s encoder guidance defines an encoder as a tool that converts video into a digital format for streaming. That describes a function, not necessarily a box on your desk: in cloud file playout, the provider handles the conversion and broadcast role for uploaded files. The meaningful distinction is who supplies the changing live feed and who has to keep that source operating.
There is also an output-side meaning of custom RTMP. A playout service may broadcast its cloud playlist to YouTube and, if supported, send the same programme to a custom RTMP destination. That does not mean it accepts an external encoder feed. For a fuller explanation of destination URLs and keys, see what custom RTMP means in practice.
Cloud playlist playout versus custom RTMP input
A cloud playlist is a fit when the material is already finished and the schedule is predictable: devotional songs through the morning, a lofi set overnight, or a local information loop that changes only when you upload a new version. You spend time preparing files, ordering them and checking the broadcast, rather than running an encoder continuously on a local machine.
External RTMP input is a fit when something must be generated live or changed in the encoder: a presenter joins, a camera switches, graphics update, or a game feed changes from moment to moment. The managed RTMP service receives that output from the encoder. It does not automatically turn arbitrary source files into a scheduled playlist unless the provider documents a separate file-playout feature.
A service can document both functions without requiring them to be used together. For example, you might use its file playout for an overnight archive loop and its RTMP ingest for a separately produced event. Alternatively, the only reason to use custom RTMP may be that a downstream destination requires an RTMP URL and key. Write down the actual source, destination and operator before treating “custom RTMP” as a requirement.
This distinction also matters for support. If a YouTube broadcast stops while using cloud playout, investigate the uploaded file, playlist, channel connection and provider’s handling of a dropped broadcast. With external ingest, add the encoder’s output, local network, RTMP credentials and managed receiver to that chain. A local source can fail while the cloud receiver is healthy; cloud file playout removes that particular dependency but does not eliminate the need to verify channel status and stream health.
What Gyre documents
Gyre describes a YouTube-focused workflow in which you upload video files, arrange them as a playlist, connect a YouTube account and run a continuous stream from its cloud service. YouTube’s own help page lists Gyre among cloud-based tools for streaming pre-recorded video continuously. These descriptions make Gyre relevant when the content is a prepared library and your intended destination is YouTube.
Gyre also describes its output as a standard RTMP live broadcast. That wording alone should not be read as confirmation that you can specify any arbitrary custom RTMP destination, nor as proof that Gyre accepts a feed from your own external encoder. Those are different capabilities. If your requirement is to ingest OBS into a managed RTMP server, ask Gyre directly for documentation of that exact path rather than inferring it from the existence of an RTMP output.
For a channel that mainly plays music or devotional material, the central practical questions are how playlists are ordered, whether the repeat behaviour suits the intended schedule, what file requirements apply, and what happens after a disconnect. The available research does not establish a like-for-like account of all current Gyre plan limits, support terms or restart behaviour, so confirm these points in the current vendor documentation before committing. Do not infer expected audience growth or monetisation from a feature page.
If your need is simply to keep finished material on air while your own computer is off, examine cloud playlist playout first. For a local production setup that must stay live from an encoder, look for explicit encoder-ingest details instead. A guide to planning a 24/7 Tamil music radio stream can help you think through the content and channel side separately from the transport method.
What Castr documents
Castr documents uploaded-video broadcasts as well as managed RTMP ingest. For prerecorded content, its page describes uploading MP4 files, scheduling a broadcast or looping a playlist, and sending the stream to YouTube. It also describes custom RTMP destinations for prerecorded broadcasts. Separately, its RTMP server page describes receiving an external encoder feed, including feeds from tools such as OBS, vMix or Wirecast, and distributing that received feed.
Those descriptions make the ambiguity especially visible. “Custom RTMP” on a prerecorded-stream page can refer to the destination of Castr’s cloud-played programme. “RTMP server” can refer to a receiver that accepts the programme produced by your encoder. One is cloud playout sent outward; the other is encoder output sent inward. Castr’s documentation describes both capabilities, but that does not mean your particular setup must join them into a single workflow.
Castr states that continuous 24/7 infinite-loop mode is available on Premium and higher plans. Playlist size, storage, file duration and concurrent prerecorded streams vary by plan according to its documentation. These are operational gates rather than small-print details: a playlist that exceeds an upload or duration limit can change the workflow you can actually run. Plan names and limits can change, so check Castr’s prerecorded streaming page and RTMP server documentation directly before purchase. Do not treat this article as a current plan matrix.
If you are already using OBS to create a composed scene, managed RTMP ingest may preserve that way of working while moving the receiving and distribution function to a provider. If you have no changing live source and only need old recordings played in order, starting with external ingest may add an encoder and network dependency without solving a problem you have. Castr is one documented example where the two capabilities exist, not evidence that every cloud service offers both.
When the workflows may be combined
A combined workflow is useful only when each stage has a job. One case is a live event that uses an external encoder for a presenter and camera, followed by a return to scheduled prerecorded material. Another is a production team that uses cloud playlists for routine hours but keeps OBS and managed RTMP ingest for interviews or special broadcasts. The switch between sources needs a clear operator and a tested handover; do not assume a playlist will automatically take over when the encoder stops.
A second case is distributing cloud-played content to more than one destination, where the provider explicitly supports YouTube and a custom RTMP endpoint. Here, custom RTMP is an output destination, not an input. Confirm whether the same playlist can be sent to both places, whether each destination needs its own setup, and how a failure on one destination affects the other. The research notes establish that Castr documents custom RTMP destinations for prerecorded streams, but do not settle every operational detail of multi-destination use.
A third case is using an encoder to create a composite that is itself continuously changing: for example, a presenter-led station with scheduled music between segments. In that arrangement, the encoder is not merely being used because the word “RTMP” appears in a product page; it is actively creating the programme. If you only have static or completed files, simpler cloud playout may be easier to operate.
The fallback playlist guide is useful when planning what viewers should see if a live source becomes unavailable. A fallback plan is not the same as automatic failover: ask which product behaviour is documented, what you would have to trigger manually, and whether the backup content has been tested on the actual channel.
Compare setup and operator responsibilities
The table compares the responsibilities implied by each workflow, not service quality. Vendor feature statements establish what a provider says it supports; they do not prove independent reliability, a particular uptime level or a YouTube outcome.
| Question | Cloud file playout | External encoder to managed RTMP |
|---|---|---|
| What supplies the programme? | Uploaded files arranged into a playlist | A live feed produced by OBS or another encoder |
| What must be prepared? | Files, order, schedule, destination channel and permissions | Encoder scene or source, output settings, RTMP URL and stream key |
| What stays active locally? | Usually no local playback computer for the ongoing cloud broadcast | The encoder and its source must remain available while sending the feed |
| What does the cloud service do? | Plays uploaded files and sends a live broadcast | Receives the incoming feed and, as documented, passes it to destinations |
| What can interrupt the workflow? | Invalid or unsuitable files, playlist or account setup, provider or destination issue | Any of those destination issues plus encoder, source, network or ingest issue |
| What must you verify? | Looping, schedule, file limits, channel connection and recovery behaviour | Supported ingest protocol, encoder compatibility, destination routing and recovery |
For a small devotional channel with a prepared set of bhajans, the first column may mean fewer overnight tasks: upload, order, connect and check. For a study stream with a live timer, changing overlays or a human host, the second column may better fit the production because the picture is not just a static playlist. A local encoder gives you control over composition but also leaves you responsible for its power, software, network and credentials.
If a Windows update, router restart or power cut has previously stopped your channel, consider which failure you are trying to remove. A cloud playlist avoids relying on your home computer for the repeated playback, but it does not guarantee uninterrupted service or remove YouTube-side checks. Our guide to keeping a YouTube lofi stream running after Windows updates discusses the local-computer failure mode; a cloud workflow changes that dependency rather than proving every other part cannot fail.
Questions to verify before choosing
Ask the provider to describe your exact signal path in ordinary language: “I upload files and you play them to YouTube,” or “I send OBS to your RTMP server and you forward it to YouTube,” or “you play files and send that output to my custom RTMP destination.” If sales or support answers only with a feature label, request a product help page or setup steps showing the direction of the feed.
For cloud playout, check file formats and size or duration caps, playlist capacity, scheduling, repeat behaviour, and whether you can replace a file without rebuilding the whole sequence. Check whether the channel connection stays authorised and what notification or recovery information you receive if a stream stops. If the stream carries music or worship recordings, independently confirm your rights and YouTube’s current rules; a vendor’s playback feature is not a rights clearance or a promise of monetisation eligibility.
For encoder ingest, check whether the service accepts RTMP, RTMPS or both, where its stream key is entered, whether it supplies one destination or more, and what happens if the incoming feed drops. Confirm that your encoder can output the required format and that your internet connection can sustain it. A test run should include stopping and restarting the encoder, checking the YouTube viewing page, and ensuring that private stream keys are not shown on screen or shared casually.
For either path, compare current plan limits, support hours and service terms on the provider’s own pages. Castr’s page describes tier-dependent constraints, and providers may change the plan matrix; Gyre’s documentation should likewise be checked for the particular destination and controls you need. Do not use vendor growth claims, generic testimonials or an unverified uptime statement as a substitute for a written answer about your workflow. Neither vendor capability nor a successful test guarantees YouTube approval, discoverability or revenue.
Finally, identify the person who checks the channel. A 24/7 broadcast still benefits from a practical routine: verify that the stream is live after setup, review the picture and sound, and know who can respond if a notice or source problem appears. If no one can operate an encoder at night, that argues for removing the encoder from the routine path where possible, not for assuming no monitoring is needed.
For a prepared file library where the main burden is leaving a computer on and responding to local restarts, StreamNeo can remove that specific local-playback burden by taking an uploaded video and running it as a YouTube live stream from the cloud; it is YouTube-only, so it is not a fit if your required destination is another platform or your workflow needs an external encoder feed.

FAQ
Does a cloud loop need a custom RTMP encoder?
Not necessarily. If you upload finished files to a service that plays them to YouTube, the service performs the cloud broadcast role; you do not necessarily need to run OBS or another encoder yourself. You need an external encoder when you have a live source to send into a managed RTMP service, or a documented workflow specifically calls for one.
Is a custom RTMP destination the same as an RTMP server?
No. A custom destination is where a service sends its outgoing stream, while an RTMP server can be a receiver for an encoder’s incoming feed. Ask whether the provider is describing input or output before you configure a URL and key.
Which is simpler for a 24/7 channel of finished videos?
Cloud playlist playout is usually the more direct workflow when the content is complete and needs only to repeat or follow a schedule. You still need to check file limits, playlist controls, account connection and recovery behaviour, and simplicity does not guarantee uninterrupted streaming.
Can I assume a provider that loops files also accepts OBS?
No. Treat file playout and external RTMP ingest as separate documented capabilities. Confirm the exact combination with the provider, because support for one does not establish support for the other.
