First check whether YouTube says the broadcast has ended or whether it is still live while the video has stopped. Those are different failures: the first points you towards transmission and event status; the second towards the source player, playlist or automation that should supply the next video.
There is no evidence here for one universal cause, and 4K60 settings do not determine whether a playlist repeats. Treat loop behaviour and encoder ingestion as separate diagnostic tracks, and note what the YouTube event, encoder and source player each report before changing anything.
Check whether the broadcast is still live
When the first video finishes, look at both the Live Control Room and the public watch page. Record whether the event is still live, whether its preview is moving, and whether the encoder says it is sending. Check at the time the symptom occurs if possible; a later visit may show an archived event or a restarted broadcast rather than the original state.
If the event has ended, the problem is not simply that a video stopped advancing. YouTube’s encoder guidance says that ending a stream involves stopping content transmission from the encoder. That makes the encoder’s running and sending state important evidence, but does not prove the encoder caused this particular stop. Check the event status and the source together rather than assuming one caused the other. See YouTube’s encoder streaming guidance.
If the event remains live but the preview is frozen, black or no longer changing, the event and its incoming content are out of step. The source may have reached the end of its queue, stopped decoding, or failed to provide the next item while the broadcast session stayed open. In that case, changing YouTube’s event settings is unlikely to fix an unverified player or playlist condition.
A useful first note is a short timeline: when the first video ended, what the source did, what the encoder displayed, and what the event status showed. If you run a devotional, music or store-promotion loop, also note whether the final frame remains visible, the preview goes blank, or the whole event closes. These observations narrow the next check without assuming the same cause for every setup.
For a broader view of the transmission side, compare the symptom with why an FFmpeg stream can show offline after starting. That issue is not the same as a loop ending, but it is a useful reminder to distinguish a live event from a healthy feed.
Determine whether the source stopped or failed to advance
Once you know the event remains live, inspect the component that supplies video. This could be a media player, playlist application, encoder scene, scheduled automation or a workflow that hands one file to another. Find out whether it still has an item queued and whether it is attempting to open the next item.
Look at the source player’s own status at the boundary between videos. Does playback stop at the last frame, return to the first frame, show an error, or disappear? If the player has a playlist view, capture the queue order and the state of the first item after the current one. A YouTube preview that keeps showing the final frame, while the event stays live, is consistent with a source that is no longer advancing; it is not proof of a particular loop-setting error.
Check whether the source is configured to repeat the current item, repeat the full playlist, or stop at the end. These behaviours are not interchangeable. A repeat-current-item setting may keep one video running but never move through a queue; a playlist set to stop may play every item once and then leave the broadcast without new content. The names and locations of these controls vary by application, so use the documentation for the player or encoder you actually use.
If the next file fails to load, check that it is available to the application, that its path or file name has not changed, and that its format can be decoded in the active workflow. If the source is remote or scheduled, verify that the next item is actually assigned and available at the time it is due. Do not replace equipment or alter stream resolution until you have evidence that the source can or cannot advance.
For background on building a queue intended to run continuously, see how a 24/7 YouTube gaming stream uses a playlist. The content may differ from your channel, but the useful diagnostic distinction is whether the sequence is configured to continue beyond one item.
Inspect playlist and source loop behaviour
A playlist can look correct at a glance and still have an end condition. Check its repeat or continuation mode, the order of items, and whether the application treats the list as a queue that empties after one pass. If the playlist contains only one video, repeating the playlist may still appear different from advancing through a multi-video sequence. Test the specific behaviour you expect: replay the same file, move from file one to file two, then continue through the end of the list.
When a single source is meant to repeat, test it locally or in a private test event before relying on it. Watch the transition at the file boundary rather than checking only that the first minutes play. A file may play successfully from beginning to end while the player still has no instruction to reopen it. Conversely, the player may be configured to repeat but encounter an unsupported transition or missing file when it tries.
In an encoder with multiple scenes or media sources, check which source is active and whether its playback state resets when it reaches the end. A scene can remain on screen while its media source has ended. If an automation rule is supposed to restart it, inspect the rule’s trigger and the action it takes. Do not conflate a scene staying selected with the underlying video continuing to play.
Third-party applications expose different controls, and the official YouTube guidance does not document their playlist logic. Avoid treating any one menu option as a confirmed fix for all players. If you use OBS media sources, the article on an OBS media source ending after one video is a relevant application-specific comparison, but verify its steps against your OBS version and actual source configuration.
If the loop behaves correctly in a local test but stops only during a live broadcast, compare what the player does with what the encoder receives. A local preview can establish that the source advances, while a live preview can reveal whether that changing picture reaches YouTube. This separates source behaviour from the next link in the chain.
Review encoder transmission and YouTube status
If YouTube’s event ended, or its preview stopped receiving a changing feed, inspect the encoder’s transmission state and messages around the same time. Record whether it is still connected and sending, whether it shows an error, and whether the stream preview changes. YouTube recommends monitoring stream health and messages and checking the preview before starting; see its streaming tips.
A brief network interruption may affect transmission, but the fact that a source stops after one video is not by itself evidence of a network fault. Check the stream health indicators, encoder log and available upload capacity before attributing the symptom to the connection. If the encoder reports that it is sending continuously while only the source image is static, return to the player and its loop behaviour.
If you use HLS ingestion, review HLS requirements specifically. YouTube’s HLS ingestion guidance specifies TS segments, segment durations from one to four seconds, a rolling playlist with no more than five outstanding segments, and HTTPS POST/PUT. These conditions apply to HLS; they are not general loop controls, and you should not apply them to an RTMP workflow.
YouTube states that streams under 12 hours are automatically archived in its encoder guidance. That archive behaviour does not explain why a source stopped after one video, nor does it establish that the stream was healthy beforehand. Use the event record as supporting evidence, not as a substitute for checking what the encoder and source were doing when the symptom began.
Check logs and reproduce the stop
Before changing settings, gather a small set of facts: encoder or player name and version, ingestion protocol, codec, configured resolution and frame rate, bitrate, stream-health messages, event status, and the source’s state at the end of the first video. Add the time of the failure and whether the preview kept moving. This gives you a comparison point and makes it easier to ask a useful question of an application’s support team.
Read the log around the transition, not only the last line after the event has ended. Look for a source end-of-file message, a failed attempt to open the next item, a disconnection, an encoder error or an explicit stop command. A log entry is evidence of an event in that application; it does not necessarily show what YouTube or another component saw. Compare timestamps across applications where possible.
Then reproduce the issue with the same playlist and representative video, ideally in a controlled test rather than on the channel’s main audience-facing event. Note whether the source advances locally, whether the encoder continues sending, and whether YouTube’s preview follows. Change one relevant setting at a time, then repeat the test. If you change loop mode, codec, bitrate and network at once, a successful test will not tell you which change mattered.
For a pre-recorded continuous broadcast, the event replay workflow offers another comparison for thinking through the content source and the broadcast as separate parts. The important point is to test the hand-off between items, not merely confirm that one file can be sent successfully.
Treat 4K60 settings as a separate diagnostic
Only investigate 4K60 ingestion after recording the source and event behaviour. YouTube’s published settings for 2160p at 60fps are codec-dependent: the returned settings table lists AV1/H.265 minimum and maximum bitrates of 10 Mbps and 40 Mbps, and recommends 35 Mbps for H.264. Verify the current guidance for your encoder and selected codec before changing values; do not use a number for one codec as if it applied to another. See YouTube’s live encoder settings.
The same guidance recommends a two-second keyframe interval and says not to exceed four seconds. It also says 4K streams use normal latency rather than the low-latency option. These are ingestion and delivery settings. They can help you assess whether a 4K60 feed matches YouTube’s published requirements, but they do not tell a playlist to repeat or explain why a source stopped at the end of a video.
Check that the available upload bandwidth can support the total stream bitrate, with room for normal variation. YouTube’s streaming tips recommend leaving 20% bandwidth headroom. Run an upload test under conditions representative of the stream and watch health indicators during a test; a single speed result is not a guarantee of a stable overnight connection. If stream health is poor, investigate transmission separately from the loop state.
The distinction matters in practice. If the event ended and the encoder reports a transmission failure, investigate the feed and connection. If the event remains live, the encoder is sending, and the preview holds the last frame, start with source advancement. The same 4K60 configuration could be present in either case, so it is not a diagnosis on its own.
Validate the correction before relying on it
After changing a source or encoder setting, run a test long enough to pass the exact point where the previous attempt stopped. Include the same file boundary and, if the usual queue has more items, let it advance through more than the first item. Confirm that the source changes, the encoder remains active, and the YouTube preview shows the change. One successful playback of the first file does not test the failure condition.
If the broadcast is intended to stay live overnight, test the actual operating pattern before depending on it: same playlist, same encoder, same protocol, and the expected connection. Keep a note of the setting changed and the result. Avoid calling a fix permanent on the strength of a short test; a repeatable test gives better evidence but cannot guarantee that future transmission will not be interrupted.
For channels where a personal computer shutting down or needing attention is the operational problem, StreamNeo removes that specific need by turning an uploaded video into a YouTube live stream that can keep running with your own computer switched off. It does not diagnose why an existing player failed to loop, and it is YouTube-only; first establish that an uploaded-file workflow suits your channel and its content.

FAQ
Why does my YouTube Live stream stop after one video?
There is no single confirmed cause from that symptom alone. Check whether the event ended or remained live, then inspect the source player’s loop or playlist behaviour and the encoder’s transmission status.
Can 4K60 settings make a playlist stop repeating?
The published 4K60 bitrate, keyframe and latency guidance concerns stream ingestion, not playlist repetition. Check those settings if the feed or stream health is poor, but investigate loop behaviour separately.
What should I record before asking for help?
Note the event status, source behaviour at the file boundary, encoder status and messages, application versions, protocol, codec and current stream settings. A timestamp and a short test showing whether the source advances locally can make the report more useful.
Should I buy a new encoder or router?
Not before you know which part stopped. If the event remained live and the source stopped advancing, replacing network equipment may not address the cause; collect the player and transmission evidence first.
