Larix Broadcaster can send a phone’s live camera and microphone to YouTube Live through an encoder connection. Entering YouTube’s server URL and stream key gets the video to YouTube; it does not make a phone a dependable unattended 24/7 playout system.
If you need a camera feed, test the actual phone, power supply and network, and arrange for someone to notice interruptions. If you need prerecorded video to play continuously, that is a different workflow. Also plan for the replay: YouTube says streams longer than 12 hours may not be captured as an archive.
What Larix can send to YouTube Live
Larix Broadcaster is a mobile encoder: it captures live video and audio on a supported phone and sends them to a streaming destination. YouTube lists Larix among its mobile encoder options, and Softvelum documents a connection workflow using RTMP. The encoder is therefore a way to transmit a live camera scene, not a tool that turns a video file into an endless playlist.
That difference matters when you plan the channel. A temple, shop, classroom or outdoor view is a live camera use case. A bhajan recording, lofi mix, nature film or daily news package that must play while nobody is at the phone is prerecorded playout. A phone encoder’s ability to connect to YouTube does not establish that it can schedule or repeat those files without supervision.
For the live-camera case, Larix handles capture and sending. YouTube Studio handles the stream’s destination-side setup and gives you the preview and health indicators. Your phone, its operating system and the network still determine whether capture and transmission continue. A connection that works for a short test proves only that the components can communicate under those conditions.
If your plan is instead to rotate recorded clips, first decide how those files will be prepared and played. Our guide to converting recorded MP4s for YouTube Live covers file compatibility; it does not turn Larix into a file playout system. For a church or devotional channel comparing continuous prerecorded workflows, see cloud services for continuous sermon streaming, and check that any approach fits your rights and operating needs.
Two different meanings of “24/7”
A live phone camera sends what the lens and microphone capture at that moment. If the phone is aimed at a fixed scene, the audience sees the room or view as it changes; if the app stops capturing, there is no new camera picture to send. A prerecorded stream instead plays media files as a programme, potentially in a planned sequence or loop. The content may look live to a viewer, but its source is prepared video rather than the phone’s camera.
These workflows ask different things of you. With a camera, you need a device that stays awake and usable, a stable mount, reliable power, adequate upload capacity and a person or process that can respond to a failed connection. With prerecorded playback, you need media prepared in an accepted format, an encoder or playout arrangement that can keep presenting it, and a plan for changing or repeating material. Do not buy a phone accessory or configure Larix on the assumption that it will solve the second problem.
Softvelum’s guidance describes different background behaviour on Android and iOS. On Android, Larix can continue streaming in the background until the app is explicitly closed. On iOS, backgrounding makes the camera and encoder inaccessible, leaving only audio. That means you should not treat a locked or backgrounded iPhone as a camera video source for an unattended continuous stream. Check the current Larix documentation and test your own device before relying on any behaviour.
If your requirement is video files running around the clock, YouTube’s encoder directory describes Gyre as a cloud service for continuous prerecorded-video streaming. That is a separate category from Larix’s camera capture, not a Larix setting. A nature playlist loop made with VLC is another distinct workflow to investigate if you are prepared to keep a computer and its playback setup running. In either case, test the precise process you intend to use rather than inferring unattended reliability from a successful camera test.
Prepare YouTube Live and the encoder connection
Before configuring Larix, make sure the channel is allowed to stream. YouTube Help currently says a channel needs to be verified, must have no live-stream restriction in the preceding 90 days, and the person streaming must be at least 16. First-time live activation may take up to 24 hours. These are YouTube’s stated requirements, not a guarantee that every channel will be enabled immediately; check the current live-streaming eligibility guidance before a planned start.
In YouTube Studio, open Create, choose Go Live, and create or select an encoder stream in Live Control Room. Set the title, privacy and other stream details for the broadcast you intend to run. The Live Control Room supplies a server URL and a stream key. They are distinct pieces of connection information: the URL identifies where the encoder sends its feed, and the key identifies which stream it should enter.
Treat the key as a password. Do not include it in a public screenshot, a shared checklist or an unredacted support message. If it is exposed, replace or reset it using YouTube Studio and update the encoder connection. Keep an unambiguous private note of which connection belongs to which channel; a mistyped or stale key can make troubleshooting confusing, particularly if you manage more than one broadcast.
YouTube’s encoder settings guidance covers supported transport, codecs and quality settings. It recommends RTMPS where available, constant bitrate (CBR), a two-second keyframe interval, and no more than four seconds between keyframes. These are encoder recommendations for YouTube ingestion, not a promise that the phone or mobile connection can sustain a chosen quality. Start with a modest setting that fits measured upload capacity, then verify the actual stream in Live Control Room.
Connect Larix with the server URL and key
Install Larix Broadcaster from the appropriate app store and grant the permissions it needs to use the camera and microphone. In the app, add a connection and enter the server address and stream key in the fields provided by the current version. Softvelum documents the relationship between the server/application address and key; its YouTube example uses the RTMP address rtmp://a.rtmp.youtube.com/live2 followed by a slash and the key. Use the server URL YouTube currently shows for your stream rather than assuming an older example is still the correct choice.
If YouTube offers an RTMPS server address, prefer that secure transport where the app and connection support it. Do not paste the entire server URL into the key field or append a second key if the app asks for server and key separately. App layouts can change, so use the current Larix instructions if field names differ. Keep the key hidden while entering or checking the connection.
Choose a resolution, frame rate and bitrate based on what the phone can capture and the upload connection can sustain. For reference, YouTube’s current table lists H.264 720p at 30 frames per second with 3 Mbps minimum and 8 Mbps recommended; for H.264 1080p at 30 frames per second it lists 5 Mbps minimum and 14 Mbps recommended. Those figures are YouTube’s ingestion recommendations, not a minimum internet-speed guarantee or a claim about what Larix will deliver on your handset. Leave room for upload variation rather than setting a bitrate equal to a speed-test result.
The Larix settings available can differ by operating system. Softvelum says Android bitrate is entered manually, while iOS offers preset values and defaults based on resolution. It also notes that mobile encoders use system encoders, so a particular phone may not hold an exact frame rate. If the picture or sound breaks up, lower the encoding demand and test again before you commit to a long broadcast. You can also read our low-volume troubleshooting guide for YouTube internet radio for practical checks on signal level and listening tests.
Start with an unlisted test if appropriate. In Live Control Room, wait for the preview, inspect stream health and listen to the audio from another device. Confirm the image has the expected orientation, focus and exposure, and that the microphone is not covered or picking up an avoidable hum. Do not rely on seeing a picture on the phone itself; confirm what reaches YouTube.
Test power, network and device behaviour
A phone that streams successfully for a few minutes may still fail in a warm room, on a congested connection or after an operating-system prompt. Run a representative test using the same mount, charger, cable, app settings, network and room temperature you expect to use. Include the actual scene and sound: a still image does not reveal how motion, changing light or a loud sound affects the stream.
Test the upload connection at the place where the phone will sit, at the time of day when the channel is likely to run. A speed test is only a snapshot. Watch the live health indicators and picture over a sustained period, and note whether the connection changes when other people use the network. If you use mobile data, verify coverage and data arrangements with your provider; do not assume a signal shown on the phone means stable encoder upload.
Power is equally practical. Use a compatible charger and cable, secure the phone so that the connector is not under strain, and make sure the charging arrangement does not obstruct ventilation. Continuous camera use and charging can add heat, but there is no universal safe runtime for every device and environment. Check for temperature warnings, dimming, charging pauses, app closure or a battery level that declines while plugged in. Stop the test if the device becomes uncomfortably hot or behaves abnormally.
Test how the phone behaves when you leave the app, lock the screen, receive a call, lose Wi-Fi briefly or let the network switch. On iOS, backgrounding the app prevents camera video capture according to Softvelum’s guidance, so a camera stream requires the app to remain in the foreground. On Android, background streaming is documented as continuing until the app is explicitly closed, but that does not establish how a particular device handles heat, battery optimisation, updates or an interrupted network. Turn off disruptive notifications where suitable, but do not mistake a setting change for proof of reliability.
Write down the settings and conditions that passed your test: phone model and OS, Larix version, chosen quality, network, charger, mounting position and any observed interruption. Repeat the test after a meaningful change, such as a different router, app update or phone. If a second person will operate the channel, let them practise reading the preview and recovering the stream before the public launch.
Monitor interruptions and plan restarts
An always-on channel needs a way to detect that it is no longer live. Keep Live Control Room available on a separate device or computer during initial operation, and agree who checks it and what they will do if the preview disappears or stream health degrades. A viewer message may be the first warning, but it is not a dependable monitoring plan. For a small business or devotional channel, a simple rota and a private contact method can be more useful than assuming the phone will reconnect by itself.
Decide in advance how to respond to a brief network interruption, a closed app, a phone restart or a power failure. The recovery steps might be to restore the network, open Larix, confirm the selected connection and start sending again, then confirm the preview in Studio. Test these steps during a private or unlisted session. The reviewed documentation does not provide a universal guarantee of automatic reconnection or uninterrupted operation across phones and networks, so do not build a promise to viewers around it.
A restart can also affect the public experience. If a session ends, a viewer may need to reopen the stream or wait for the new broadcast, and the new segment may have a different link or appearance. Communicate planned maintenance plainly, and keep a written runbook with the channel, stream name, connection choice and recovery contact. Never place the stream key in that runbook if it will be shared broadly.
If what you actually need is for a programme to continue while the operator is away, compare the work of maintaining a phone camera setup with a dedicated continuous playout workflow. For example, a bhajan channel workflow using Switchboard Live is relevant to prerecorded devotional programming, whereas it is not an alternative camera mode inside Larix. StreamNeo can remove the need to leave a personal computer running for a prerecorded file-based YouTube broadcast: you upload the video, provide the channel’s stream key, and the broadcast can run with your computer off, with monitoring and restart handling. It is YouTube-only, and it does not solve the distinct need for a phone camera feed.
Plan for archives and local recordings
Do not assume YouTube will preserve a complete replay of a 24-hour broadcast. YouTube Help says a stream longer than 12 hours may not be captured at all, and recommends making a local archive as a backup. This is an archive caveat, not a statement that YouTube automatically ends every live stream at that duration. Check the current archive guidance and verify the result after a test rather than relying on an expected replay to exist.
If a YouTube replay matters, one practical approach is to plan shorter sessions and restart at a time that suits the channel. Segmenting still requires an operator or a tested workflow to stop and start the broadcasts, and it may create gaps or separate archive entries. Confirm how the channel’s Live Control Room presents the stream and whether the resulting replay is available before advertising that viewers will be able to watch it later.
A local recording offers another layer of protection, but it has its own limits. Check whether the phone and app can record locally while sending, how much storage is available, whether the file remains playable after an interruption, and whether the device can handle the extra workload. A separate recording device may reduce reliance on one phone, but it adds another battery, storage and file-checking task. Make a test recording, play it back on a different device and confirm both picture and sound.
For content that must be preserved, decide who copies the file, where it is stored, how long it is retained and how a failed copy will be noticed. Label segments with date and programme details, and avoid treating a phone’s camera roll as the only archive. If the recording includes music or other third-party material, check the relevant rights and YouTube’s current policies separately; a local copy does not change those obligations.
Before committing, compare the operating options on the pricing page. When the file and channel are ready, start free — 24-hour trial, no card.
FAQ
Can Larix Broadcaster run a YouTube stream continuously from a phone?
Larix can send a live phone camera feed to YouTube, but that capability alone does not establish reliable unattended 24/7 operation. Test the actual device, power, network and recovery process, and arrange monitoring. On iOS, backgrounding removes access to camera video; Android behaviour can still vary by device and conditions.
Where do I put the YouTube stream key in Larix?
Create or select an encoder stream in YouTube Studio and copy the server URL and stream key shown in Live Control Room. Add a Larix connection and enter those details in the appropriate fields for the current app version. Keep the key private, as it is a credential that can direct a broadcast to your channel.
Will YouTube save a 24-hour stream as a replay?
It may not. YouTube warns that streams longer than 12 hours may not be captured as an archive, so use a local recording backup if the footage matters and verify it after a test. Planned shorter sessions may help with replay planning, but require a safe, tested restart process.
Can I use Larix to loop prerecorded videos?
Larix’s documented use here is encoding live camera video and audio from a phone, not scheduling or looping a collection of files. For prerecorded playback, choose a separate playout workflow and test its continuity, rights and archive plan. Do not treat a successful Larix camera connection as evidence that prerecorded video will keep playing unattended.
