Larix Broadcaster can send your phone’s camera and microphone to a YouTube Live stream by using the stream URL and key from YouTube Studio. It can support an extended broadcast, but configuration alone does not make it an uninterrupted 24/7 system.

A continuous camera feed still depends on YouTube activation and session handling, the Larix app and phone, power, heat, and a reliable upload connection. In particular, Larix documents different background behaviour on Android and iOS; do not assume an iPhone will keep sending video if the app is backgrounded or the phone is locked.

What an always-on Larix setup can mean

Larix Broadcaster is a mobile encoder: your phone captures live video and audio, encodes it, and sends the feed to a destination. Softvelum lists YouTube Live as a supported destination. That describes a way to publish from a phone, not a promise that a phone can operate unattended without interruption. See Softvelum’s Larix documentation for its product and destination information.

For a short event or a staffed camera, the distinction may not matter much. You can keep the app open, watch the feed and intervene if the connection drops. For a devotional channel, a shop floor camera or an overnight ambience stream, interruptions matter more: someone may need to restore the phone, reconnect the app, or deal with a YouTube session that needs attention.

The practical meaning of “always-on” should therefore be a requirement you test, not a setting you switch on. Decide whether the phone must run only while attended, whether occasional restart is acceptable, or whether no one can be present to recover a failure. A channel that needs a repeating playlist of existing videos has a different job from a live phone-camera feed. For a file-based channel, automating video rotation on a 24/7 YouTube stream in India is a more relevant starting point.

Larix can be a sensible fit when you need a portable camera feed and can keep the phone in the required state. If the actual requirement is unattended operation through the night, first test the whole chain: device, app, charger, network, recovery after a disconnect, and YouTube’s handling of the session. The documentation does not establish a guaranteed 24-hour run.

Enable YouTube live streaming

Before entering anything in Larix, confirm that the channel can go live. In YouTube Studio, use Create → Go Live and follow the activation steps if prompted. YouTube says first-time activation can take up to 24 hours, so complete this well before a planned broadcast rather than discovering the delay at launch. Check YouTube’s current live-streaming activation guidance for the applicable account steps.

Once the feature is available, open Live Control Room. You can create a new stream or select one already set up for the channel. The stream you choose is important: its current server URL and stream key are the destination credentials Larix will use. If you later select a different stream, do not assume the old connection details point to it.

Treat the stream key as a password. Anyone with the key may be able to send a feed to that broadcast, so do not put it in an article, public screenshot, chat message, or support post. If you need help diagnosing a connection, conceal the key and any part of the connection URL that contains it. You can rotate or replace a key through YouTube’s controls if it has been exposed.

This activation step is a platform dependency, not a Larix setting. A working app and a good mobile connection cannot bypass a channel that is not enabled for live streaming. Equally, successful activation does not guarantee that every future session will appear live automatically; check what Live Control Room asks you to do for the particular stream.

Create or select a stream in Live Control Room

In Live Control Room, create a stream for the broadcast or select the one you intend to use. Review its title, visibility, schedule and audience details before sending video. These settings affect how viewers encounter the stream, while the encoder connection details determine where Larix sends the feed. Keep the two tasks distinct: a successful encoder connection does not itself make a scheduled broadcast public or complete any confirmation YouTube requires.

Open the stream’s encoder setup and locate the server URL and stream key. Copy the values directly from the selected stream rather than relying on a URL remembered from a previous setup. YouTube may provide an RTMP URL and, where available, an RTMPS URL. RTMPS is the encrypted form of the transport; use it when YouTube offers that URL and your installed Larix version accepts it. Follow YouTube’s encoder setup instructions for the URL currently shown in your account.

Do not confuse the stream key with the public watch link. The watch link is for viewers; the encoder URL and key are private sending details. If you are preparing a phone for a colleague, enter the credentials privately on the device and explain how to remove or replace them if the phone changes hands.

For a scheduled stream or one with manual confirmation, plan to start Larix early enough to see the incoming preview. YouTube may show an incoming signal before you choose to go live. Wait for the preview and inspect the picture and sound, then follow the on-screen controls for that stream. Do not presume that pressing publish in Larix is the same action as starting the public broadcast in YouTube.

Copy the server URL and stream key into Larix

In Larix Broadcaster, open Settings, then Connections, and add a connection. Give it a recognisable name, such as “shop camera” or “temple hall”, so you can distinguish it from test destinations. Select the video-and-audio mode for a normal camera broadcast; Softvelum’s Larix setup documentation advises using video plus audio for YouTube connections.

Softvelum’s documented setup joins the YouTube server URL and stream key into a single Connection URL. Use the URL displayed for your stream in Live Control Room, then append a slash and the actual key if the interface calls for the combined value. Softvelum illustrates the server portion with rtmp://a.rtmp.youtube.com/live2, but use YouTube’s displayed server URL rather than treating that example as a universal endpoint. The final connection contains the private key, so keep it out of anything you share.

Save the connection and select it before publishing. If YouTube gives you an RTMPS URL and Larix accepts it, choose that rather than guessing an encrypted address yourself. If it does not work, compare the selected YouTube stream, URL and key character by character, and make sure Larix is publishing to the connection you just saved.

Then start publishing in Larix. Look for an outgoing status in the app and an incoming preview or status in Live Control Room. If the preview does not arrive, avoid repeatedly changing unrelated settings. First check the connection details, selected connection, video-plus-audio mode and phone internet access. Stop publishing before editing a connection if the app’s controls indicate that is necessary, and take care not to expose the key in a screenshot.

This is a live camera workflow rather than a video playlist. If you need to repeat prepared clips, looping multiple videos on YouTube Live with OBS covers a different source and operating model. A recurring programme built around uploaded recordings also has different recovery and scheduling considerations from a camera left pointed at a scene.

Check phone, network, and power constraints

A phone must remain able to capture, encode and send the feed. The most important practical difference in Larix’s documentation is background behaviour: its FAQ says Android can continue streaming when the app is in the background until it is explicitly closed, while iOS background mode cannot access the camera or encoder and allows audio only. That is not a reason to assume any Android handset will survive unattended indefinitely. Test the actual device and app version, and keep Larix foregrounded where camera video requires it. See the Larix FAQ for current platform notes.

A screen locking, battery policy, app termination, operating-system update or device restart can alter the session. Disable or adjust battery-saving behaviour only where appropriate for the device and app, and test the result. Do not rely on an iPhone continuing camera video after you leave Larix or lock the phone. If someone must monitor the camera feed, make that person and the recovery steps part of the plan rather than treating the phone as an unattended appliance.

Power is a separate dependency from network. A charger does not prove that a phone will remain stable during a long encode: charging, bright display, warm surroundings and camera use can all contribute to heat. Put the phone in a ventilated position, secure it so the framing cannot drift, and test the full arrangement for longer than a quick setup check. Avoid placing it in direct sun or enclosing it where heat cannot escape. A mount can help with a fixed view, but it does not solve thermal, app or connectivity problems.

The upload connection must sustain the chosen picture and sound settings. A Wi-Fi signal indicator alone does not show that the uplink is stable, and a mobile data connection may vary with location and congestion. Larix describes bitrate as a target; its FAQ notes that network problems can lead to frame loss for RTMP/RTSP, and adaptive bitrate behaviour depends on protocol and platform. Follow YouTube’s current encoder recommendations, then validate resolution, frame rate and bitrate on the actual phone and uplink rather than adopting a number without regard to those conditions.

Choice What it changes What to verify
RTMP or RTMPS RTMPS encrypts the transport using TLS/SSL; it does not make a weak connection stable. Use the URL Live Control Room supplies, and confirm Larix accepts it.
Android or iOS background use Larix documents background video streaming on Android; iOS background operation is audio-only. Test the actual device and do not expect background camera video on iOS.
Wi-Fi or mobile data Both can carry a live feed, but available upload quality and continuity depend on the place and conditions. Test at the intended installation point and observe the real feed.
Phone or unattended playout A phone captures a live camera; a prepared-video channel has different scheduling and recovery needs. Choose against the content and intervention requirement, not convenience alone.

For a truly unattended installation, write down what happens after power loss, app closure, a dropped uplink or a YouTube-side interruption. A phone-based camera may suit a staffed location or an occasional extended event. If a prepared channel must continue while your own computer is switched off, the trade-offs of hosted video streaming instead of a 24/7 streaming PC are worth considering. StreamNeo removes the need to leave a phone or local computer publishing an uploaded video, which is a different workflow from Larix’s live camera capture.

Test the feed and monitor YouTube stream health

Run a preflight from the exact location and with the exact phone, power arrangement and network you plan to use. Start Larix, check that the correct connection is selected, and wait for YouTube’s incoming preview. Confirm that the camera is framed as intended and that speech or other audio is audible without clipping, excessive noise or an unexpected silent mode. A preview visible only on the phone is not enough; check the receiving side in Live Control Room.

Watch YouTube’s stream health and the feed’s bitrate or dropped-frame behaviour during the test. The point is not to achieve a universal target by copying someone else’s settings: the usable result depends on resolution, frame rate, codec, phone capability and the real upload path. If the image stutters, simplify settings and retest, or improve the uplink before depending on the feed. Keep the test unlisted or otherwise controlled if you do not want viewers to see it, and verify the selected visibility before the real broadcast.

If YouTube receives no preview, check in a fixed order: verify the currently selected stream in Live Control Room; confirm that its URL and key match the Larix connection; verify video-plus-audio mode and selected connection; then check internet access and app status. Re-enter credentials carefully if needed, but do not share the key while asking for help. If the preview appears but is unstable, look at the phone’s thermal and power state as well as the uplink rather than assuming YouTube alone is responsible.

Monitor a longer trial as well as the initial connection. A quick preview can reveal a wrong key, but not necessarily what happens when a phone heats up, loses Wi-Fi or changes network. Test the recovery procedure: who notices a stopped feed, who can reopen Larix, and whether YouTube requires another action before viewers see the stream. Keep a note of the steps that worked so a second operator can follow them.

YouTube’s automatic archive rule is easy to misread. It says streams under 12 hours are automatically archived; that is an archive-handling statement, not evidence that every stream is forcibly stopped at that point, nor proof that one live session provides an uninterrupted archive beyond it. For a broadcast expected to last longer, check YouTube’s current guidance and plan explicitly for session and archive handling. When finished, stop sending from Larix and end the stream in YouTube Studio where applicable.

Decide whether the phone is the right source

Larix is appropriate when the content is genuinely live from a camera and you can accept the device and operator responsibilities. Examples include a staffed event, a temporary view from a venue, or a live presenter who can keep the app in the required state. In these cases, the value is direct capture from a phone rather than a pre-produced sequence.

It is a less certain fit when the channel must run unattended day and night with no one available to recover the feed. You would need to validate charger continuity, heat under sustained camera use, network resilience, the device’s behaviour after an app or system restart, and YouTube’s controls for that session. The reviewed documentation does not promise that combination will stay uninterrupted. If a power cut or router restart is plausible, include it in a controlled rehearsal rather than assuming the phone will reconnect correctly.

For a channel built from a fixed library of devotional recordings, ambience footage or scheduled announcements, a mobile camera encoder may solve the wrong problem. A hosted playout workflow or a computer-based encoder can be a better fit depending on how much control and intervention you need. Compare recovery, source changes, archive requirements and who will monitor it; do not choose solely on the fact that one setup connects successfully once.

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 for 24 hours?

Larix can publish an extended feed while the phone, app, network and YouTube session remain operational, but its documentation does not guarantee uninterrupted 24-hour operation. Test the complete installation and decide how interruptions will be noticed and recovered from before relying on it.

Can Larix keep sending camera video when my phone is in the background?

Softvelum documents Android background streaming until the app is explicitly closed, while its iOS background mode is audio-only because it cannot access the camera or encoder. Behaviour also depends on the device and current software, so test your exact phone and do not count on background video from an iPhone.

Is RTMPS required for YouTube Live?

Use the RTMPS URL when YouTube provides one and the Larix version on your device supports it; RTMPS encrypts the transport. Otherwise follow the current URL shown in Live Control Room and do not construct or guess a different endpoint.

Does YouTube stop every stream after 12 hours?

The cited YouTube rule says streams under 12 hours are automatically archived. That concerns archiving and should not be treated as a statement that every stream is forcibly stopped at 12 hours; check YouTube’s current session guidance for your broadcast.
