To stream from a Samsung Galaxy to YouTube Live with Larix Broadcaster, copy the current server URL and stream key from YouTube Studio into a Larix connection, then start sending video and check the result in Live Control Room. The phone captures the picture and sound; YouTube supplies the destination details and controls for starting or scheduling the broadcast.
The precise menu names can differ by Galaxy model, Android and One UI version, and Larix release. Use the current values shown in your own YouTube Studio stream, and treat the stream key like a password: anyone who obtains it may be able to send video to your stream.
What you need before starting
Have a YouTube account with access to live streaming, your Samsung Galaxy, Larix Broadcaster, a stable internet connection, and enough battery or a charger for the session. YouTube’s encoder workflow is described in its official setup guide. Account eligibility and setup can vary; check the current YouTube guidance and Studio status rather than assuming that installing an app makes an account ready to stream.
Think about where you will be broadcasting and what the phone will show. A phone camera is suited to a presenter, a small event, a shop demonstration, or a temporary view of a space. It is less suited to a fixed, unattended channel that must loop the same video all day: a phone camera is a live camera source, not a way to turn an uploaded recording into continuous playback.
Check the upload connection at the place you intend to stream. A speed test is only a momentary indication; mobile reception and Wi-Fi congestion can change, and a stream that starts successfully may later lose picture or sound. If you are weighing a phone broadcast against an ongoing channel, the practical concerns are different from planning long-running video playback, as outlined in this guide to keeping a 24/7 meditation stream running after OBS crashes.
Charge the phone, keep it somewhere it cannot be knocked over, and consider how it will stay cool and connected. If you plan to use an external microphone, check that its connector and Android support fit your particular Galaxy before the day of the broadcast. YouTube lists external microphones and headphones as common streaming equipment, but that does not establish compatibility for every phone or accessory.
Get the YouTube server URL and stream key
Open YouTube Studio and choose Create → Go live to reach Live Control Room. Select the Stream tab. If you are setting up a first stream, edit the stream details and create a stream as prompted; if you have streamed before, you may be able to use an existing stream and its current settings. Follow the current on-screen workflow, since labels and available choices can change.
Keep the server URL and stream key available for entering into Larix. YouTube describes these as the details you enter in your encoder to begin sending a live stream. Copy the values for the stream you intend to use, not from an old note or a tutorial example. A key is a credential, so do not show it in a screen recording, screenshot, chat, or public post. If it is exposed, use YouTube Studio’s current controls to manage or replace it.
Before leaving Studio, set the stream’s title and visibility with the audience in mind. YouTube offers public, private, and unlisted visibility choices. A public stream can be found by viewers; an unlisted stream is accessible to people with its link; a private stream is restricted. Check the current privacy controls and intended audience before sharing the watch page. Do not assume a visibility default is appropriate for your account or event.
You can set up an immediate stream or prepare a scheduled stream. With an immediate stream, the encoder’s data can make the stream live as soon as it is received. For a scheduled stream, the encoder preview may appear first, and you then start the event using Go live in Live Control Room. Choose the flow that matches whether you want to go live as soon as Larix connects or wait for a deliberate start time.
Install and open Larix Broadcaster
Find Larix Broadcaster in the Google Play Store and install it from the app listing. YouTube includes Larix Broadcaster among Android mobile encoder options; its mobile encoder guidance is a useful place to confirm the current workflow. Open the app after installation and allow camera and microphone access when Android asks, if you intend to send both picture and sound.
The permission prompt wording and route to app permissions can differ across Android and One UI versions. If you denied access previously, use your Galaxy’s Settings app to find Larix’s permissions and enable only the access required for the broadcast. Do not rely on a remembered path from a different Galaxy model. Return to Larix and check that its camera preview appears and that the selected audio source is the one you expect.
You may see connection, camera, audio, or settings controls in Larix, but their names and arrangement can change between app versions. Softvelum’s Larix documentation covers its connection setup and stream options. Use it alongside the current app display rather than following a screenshot whose version you cannot confirm.
Add a YouTube connection in Larix
Create a new connection in Larix and enter the server URL and stream key from YouTube Studio. Larix’s YouTube instructions describe the RTMP connection as the server or application URL combined with the stream name or key. In practice, use the current values YouTube provides and the URL field format Larix currently requests; do not substitute a sample key or construct a destination from memory.
Check the entered values carefully before saving. A missing character, extra space, or key from another stream can prevent YouTube from receiving the intended feed. If the app presents separate fields for a URL and stream key, put each value in the matching field. If its current connection interface expects a combined connection URL, follow Larix’s documentation for that version. Do not paste the key into a public note or share it with someone helping you via a visible screenshot.
Confirm that the connection sends audio + video, not a video-only or audio-only mode. Softvelum advises checking this mode and choosing an appropriate bitrate for YouTube. “Appropriate” depends on the picture settings and the upload connection available at the location; the evidence here does not establish one bitrate that suits every Galaxy or network. Start with a setting your connection can sustain and check the received preview rather than assuming a larger number is automatically better.
If the connection does not save or later fails, compare it with the live values in Studio and Larix’s current setup documentation. Avoid changing several settings at once: correcting one field and testing again makes it easier to identify what was wrong. For audio-specific fault checks on a different encoder workflow, this YouTube stream audio troubleshooting guide offers a useful set of symptoms to think through, but Larix labels and controls may differ.
Choose the camera and check video settings
Use Larix’s camera controls to choose the front or rear camera, depending on whether you are presenting to the phone or filming a subject in front of it. Check framing before you start sending: make sure the subject is visible, the phone is stable, and bright windows or lamps are not washing out the picture. If a viewer needs to read a sign, product label, or text, check that it is legible in the actual preview rather than only on the phone’s small local display.
Review the available resolution, frame-rate, and bitrate settings, but do not assume that a setting supported by one Galaxy is supported or sensible on another. The phone model, lighting, movement, mobile signal, Wi-Fi conditions, and YouTube’s current encoder guidance all matter. If the image stutters or the preview is unstable, lower the demand on the connection or use a steadier network and test again. This is a practical adjustment, not a guarantee that a particular setting will work everywhere.
Check audio before broadcasting. Speak at the expected distance from the phone or microphone and watch for Larix’s audio indication if available. Listen with headphones if you can do so without disrupting the setup. Confirm that the app has microphone permission, the intended input is selected, and that background noise or handling is not overwhelming speech. If you intend to use an external microphone, test the exact cable or adapter with the phone in advance; connector shape alone does not prove compatibility.
A short private or unlisted test can help you check framing, sound, and delay without inviting the public to an unfinished stream. Set privacy deliberately in YouTube Studio, and use a test stream that you can identify. Do not share its link widely if it is meant only for checking.
Start the stream and verify YouTube’s preview
When the camera, audio, connection, and Studio details are ready, start sending from Larix. Watch for a connection status or other indication that the app is transmitting, then return to Live Control Room. Check that YouTube receives the encoder signal and that a preview appears. The phone’s own preview only shows what Larix is capturing; the Studio preview confirms that the feed is reaching YouTube.
For a stream intended to go live immediately, follow Studio’s current indication once encoder data arrives. For a scheduled stream, wait for its preview in Live Control Room and select Go live there when you are ready. Starting the encoder and making a scheduled event public are distinct steps. Confirm the event title and visibility before committing to the scheduled start.
After it is live, check the picture and sound from a separate viewer’s perspective if practical. A second device can reveal a muted stream, poor framing, or an unexpected public page that the phone display will not show. Keep the Galaxy powered, in a stable position, and within a reliable network area. If you are streaming a webinar or demonstration, planning the viewer experience also matters; this advice on hosting a webinar people will watch covers preparation beyond the encoder connection itself.
If YouTube receives no image or audio, first verify that the stream URL and key belong to the right Studio stream and are entered as Larix expects. Then check camera and microphone permissions and confirm the connection mode includes both audio and video. If a scheduled event is waiting rather than live, look for its preview in Studio and use the event’s Go live control when appropriate. These checks follow the documented workflow, but they cannot diagnose every device, network, or codec issue.
To finish, stop sending from Larix. YouTube says streams under 12 hours are automatically archived after encoder transmission ends; check the current YouTube help on encoder streams for current handling. If a recording matters, verify the archive in Studio rather than assuming the stream ended or saved as intended.
A phone-camera workflow is useful when you are present and can watch the device. It is not a substitute for managing a long, unattended video loop from a recording. When the recurring problem is a computer that must stay on to send a fixed programme, StreamNeo removes that specific burden by letting you upload a video and run it as a YouTube live stream while your computer is switched off.

FAQ
Do I need a stream key to connect Larix to YouTube?
Yes. YouTube Studio provides the server URL and stream key that an encoder such as Larix uses to send the stream. Treat the key as private, and use the current values for the stream you are setting up.
Why does my scheduled stream show a preview but not go live?
A scheduled stream may require you to start it from Live Control Room after the encoder preview appears. Check that you are viewing the intended event, then use its Go live control when you are ready.
Can I follow the same menu steps on every Samsung Galaxy?
Not necessarily. Menu names and permission paths can vary by Galaxy model, Android and One UI version, and Larix release. Follow the labels on your phone and consult current Larix and YouTube documentation if a control has moved.
Will this setup keep a broadcast running without interruption?
No setup sequence can promise an uninterrupted broadcast. A phone stream depends on the device, power, permissions, network, and correct YouTube connection, so test in the intended location and monitor the live preview.
