If you want to play an existing video file as a YouTube live stream, neither Larix Broadcaster nor Larix Screencaster is documented as a file player or playout scheduler in the reviewed material. Broadcaster is for live mobile camera capture; Screencaster is for live capture of a phone or tablet screen.
That distinction matters because YouTube’s scheduled event does not play your file for you: a suitable encoder or playout workflow must send the video and audio. For continuous prerecorded streams, YouTube Help lists Gyre as a cloud option and also lists OBS as live-streaming software; check each workflow’s current capabilities before choosing it.
Short answer: choose by source, not by app name
The word “stream” can describe two different jobs. One is capturing something as it happens, such as a singer, a temple service, a phone screen or a live lesson. The other is taking a video that already exists and sending it out as a live broadcast, perhaps on a loop. The reviewed Larix descriptions establish the first kind of job, not the second.
| What you want to send | Documented fit in the reviewed material | What to plan for |
|---|---|---|
| A live scene from a phone camera | Larix Broadcaster | Mobile camera capture and live encoding |
| A live phone or tablet screen, such as gameplay or an app demonstration | Larix Screencaster | Screen capture and live encoding; check audio behaviour on your device |
| A stored video file, played as a YouTube live stream | Neither Larix app is established as the file-playout tool | A file-playout and live-encoding workflow |
| A continuous prerecorded channel | A dedicated continuous-stream workflow is worth considering | Confirm its file, looping, scheduling and monitoring details |
This is a conclusion about the product documentation reviewed, not a claim that no technical workaround exists. The safe buying and setup decision is not to assume that a capture app can select a stored file and play it on a schedule. If your real source is a live camera or screen, one of the Larix apps may still fit that narrower job.
What Larix Broadcaster is documented to do
Softvelum’s Larix documentation and the Google Play listing describe Broadcaster as a mobile live-capture and streaming app. The listed source is the device camera, with features such as camera switching and overlays; the listing also describes local MP4 recording and YouTube Live as a destination. Those capabilities make it relevant when the content is being captured on the phone, rather than selected from a folder as a prerecorded programme.
For example, a small shop might point a phone at a product demonstration, or a community group might stream a live event from a phone. In each case the camera is producing the picture as the event happens. A saved recording of last week’s event is a different source: the question then becomes how to play and encode that file, not how to capture a camera feed.
The fact that an app can record an MP4 does not establish the reverse function of playing that MP4 as a live source. Recording and playout are separate operations. Before relying on any feature not apparent in the current documentation, check Softvelum’s current guide and the current listing for your device rather than inferring it from the app’s ability to save video.
Broadcaster can be relevant to a live contribution workflow even if your channel’s main output is prerecorded. You might use a phone for an occasional live announcement, while keeping the scheduled file stream on a separate workflow. Treat them as distinct sources and test how you will switch between them before announcing a change to viewers.
If your immediate problem is specifically a phone camera that will not connect, this is a different question from file playout; the guide to troubleshooting Larix Broadcaster’s YouTube connection addresses that connection path. Fixing a connection will not turn camera capture into a documented video-file scheduler.
What Larix Screencaster is documented to do
Larix Screencaster is described in the store listings as a live screen-capture app. It can be appropriate when what viewers need to see is happening on the device display: a game, an app walkthrough, a slide presentation or a live demonstration. The screen is the source, and the app sends that live capture onward to a streaming destination. The Apple App Store and Google Play descriptions list YouTube Live among the destinations or uses.
That is not the same as opening a saved video and scheduling it to play continuously. A screen capture can show a video playing on the same device as a technical route, but the reviewed descriptions do not establish that as a dedicated prerecorded-file playout workflow. It also leaves practical questions about notifications, screen locking, battery, audio routing, interruptions and what happens when playback ends. If you investigate such a route, test it directly on the intended device and do not present it as a documented scheduler feature.
On iOS, Softvelum’s guidance says screen streaming can use microphone audio, while audio from another app is available only when that app supports ReplayKit. This is an iOS-specific note, not a general statement about Android. If you are planning to stream a music player, video app or lesson, verify the audio path on the actual app and device: seeing its picture on the captured screen does not prove that its sound will reach the broadcast.
For an app demonstration with spoken explanation, Screencaster may suit the source better than a camera encoder. For a bhajan video already stored as a file, it does not remove the need to choose a file-playout workflow. Decide first whether the source is genuinely live screen activity or an existing programme, then choose the encoder accordingly.
Why capture is not file playout
A live encoder receives a changing source and packages it for delivery. With Broadcaster, that source is the camera. With Screencaster, it is the screen. A file-playout system instead reads a stored programme, sends its picture and sound in sequence, and may need to repeat it, move to another item, or continue at a scheduled time. Both jobs can ultimately supply video and audio to a live broadcast, but the source handling is different.
YouTube’s encoder instructions explain the platform side of the hand-off: you enter the live server URL and stream key into the encoder, then send a signal that YouTube can receive. For a scheduled event, YouTube Help says to schedule it in Live Control Room, connect and start the encoder at the scheduled time, wait for the preview, and then choose Go live. The event page organises the broadcast; it does not supply or play the content file.
This separation helps locate faults. If an event exists in Live Control Room but the preview is blank, check whether the selected workflow is actually producing an encoder feed. If a live feed appears but has no sound, test the source’s audio capture and encoding separately. If a prerecorded playlist reaches its final item and stops, the issue is in playout or continuation behaviour, not in the YouTube event’s scheduling screen.
For a 24/7 channel, a workflow should also account for what happens outside the first successful connection. Ask how it behaves after a file ends, whether it can repeat or move through a playlist, how it handles an interruption, and how you will notice that picture or sound has stopped. These are operational requirements to verify, not reasons to assume that any one app guarantees uninterrupted broadcasting.
YouTube says streams under 12 hours are automatically archived. That detail can matter when planning how long a single broadcast is intended to run, but it does not provide a way to play a file or schedule a continuous channel. Check YouTube’s current instructions for your event type and account, and make the source workflow responsible for producing the feed.
Alternatives documented for prerecorded streams
For a continuous prerecorded stream, YouTube Help’s live-streaming guidance lists Gyre as a cloud option for continuous prerecorded-video livestreaming. YouTube Help also lists OBS as recording and live-streaming software. Those references do not mean every product or configuration will meet your needs: the cited Help page alone does not establish a complete local-file playlist procedure for OBS, and current supported formats, features and operating terms should be checked with the relevant provider.
The practical distinction is between a service intended to run prerecorded content continuously and a general encoder that can be configured as part of a broader workflow. If you already operate a computer and know how to configure video sources and playlists, a desktop workflow may offer more control. In return, you need to consider the computer’s power, network, operating-system updates, encoding load and what happens if the application closes. A cloud-oriented workflow can reduce dependence on your own computer being on, but you should still verify its limits and monitoring tools.
A useful next step is to read a workflow that addresses the same source. The guide to looping an exam-preparation playlist on YouTube Live is relevant if you have a sequence of lessons rather than a single camera feed. For a desktop setup, keeping OBS streaming when a video playlist ends focuses on what happens at the end of a playlist. Neither guide changes what Larix documents; they help you evaluate a file-based route.
Choose based on your operating constraints, not merely the word “live” in an app listing. A single event that you can supervise from a laptop may be a reasonable fit for a local encoder. A channel intended to run overnight or while you are away needs a clear answer for file continuation, recovery and monitoring. If you want to understand the broader planning choices for how many live streams you can create on YouTube in one day, keep that question separate from the source and playout decision.
Choose a workflow for your source
Start by writing down what is supposed to create the picture. “We want a YouTube stream” is too broad to make an app choice. “A phone camera at a live event”, “a tablet screen showing a live app”, and “a folder of recorded lessons on repeat” point to different tools and tests.
If you are filming live with a phone, test Broadcaster with the actual camera position, Wi-Fi or mobile connection, audio source and YouTube destination you expect to use. Check the picture and sound in YouTube’s preview before going live. For a mobile camera stream, also decide where the phone will sit, how it will stay powered, and whether you can keep the app in the required state for the length of the event.
If you are showing a live screen, test Screencaster on the exact device and app. On iOS, check the ReplayKit condition for in-app audio in Softvelum’s guidance; if the app does not support it, do not assume the screen stream will include that app’s sound. Make a short private or otherwise appropriate test before a public event, and check whether notifications, screen orientation or another interruption would expose information or disrupt the picture.
If you have a prerecorded file, choose a workflow that explicitly explains file input and live output. For a local workflow, confirm how the file is selected, how audio is mapped, what happens at the end, and whether looping or playlist transitions are supported. For a cloud workflow, confirm upload and format requirements, scheduling behaviour, current terms and how you inspect the live result. Do not infer these details from the fact that a product can publish an encoder feed.
For a 24/7 devotional or ambience channel, prepare the content and the operations plan together. Check that the video and audio are suitable to repeat, that transitions do not leave long gaps, and that somebody can verify the live preview or replay when needed. You can use remote monitoring ideas for a 24/7 Indian music stream to plan checks from another device. Monitoring detects problems; it does not replace a workflow that can continue the file source.
Check the setup before publishing
YouTube’s encoder setup instructions are the primary reference for configuring a scheduled broadcast. Create the event in Live Control Room, use the server URL and stream key in the chosen encoder or playout system, start the feed when required, and confirm YouTube receives a preview before selecting Go live. Follow the current instructions in your account, since interface labels and available options can change.
Before the public start, make a short test that follows the same path as the real stream. Check that the correct file or live source is selected, that both picture and audio arrive, and that the preview is stable enough for your needs. For a file, test an ending or transition rather than only the opening seconds. For a screen capture, test the exact audio behaviour and notifications. For a camera feed, check framing and ambient sound.
Keep the stream key private. If you share access with someone helping you set up, give only the access they need and follow YouTube’s current account guidance. A correctly configured key does not guarantee that the broadcast is suitable for publication: you are still responsible for the rights and permissions relating to the video, music, images and other material you send. Check current official guidance where you are unsure.
Plan how you will notice a failure after the event starts. Open the live page or monitoring view on another device, confirm that viewers can see and hear the programme, and decide who will respond if the feed stops. A green connection indicator alone may not tell you that a file has ended, audio has gone silent or the wrong source is playing.
If the work is a continuous file stream and leaving a computer running is the specific burden you are trying to avoid, StreamNeo turns an uploaded video into a YouTube live stream without keeping your own computer on for the broadcast.

FAQ
Can Larix Broadcaster play a prerecorded video file to YouTube?
The reviewed Broadcaster documentation describes mobile live capture and streaming, not a prerecorded-file player or playout scheduler. If you need to send a saved video, select a workflow that documents file playout and verify its YouTube encoder setup.
Can Larix Screencaster stream a video that is playing on my phone?
Screencaster is documented for live screen capture, so a playing video may appear as screen content in some device and app configurations. The reviewed material does not establish it as a dedicated file scheduler, and captured app audio may depend on platform and app support; test the precise route rather than relying on it for a continuous channel.
Does scheduling a YouTube event make the prerecorded file play?
No. Scheduling creates the event, while an encoder or playout system must provide the video and audio feed. YouTube’s encoder workflow describes connecting that feed and checking the preview before going live.
What should I use for a continuous prerecorded YouTube stream?
YouTube Help lists Gyre for continuous prerecorded-video livestreaming and also lists OBS as live-streaming software. Check the current product documentation for file support, looping, scheduling, operating terms and monitoring, then choose the workflow that matches how much of the stream you need to supervise.
