You can use Larix Broadcaster to send a live mobile encoder feed to YouTube Live over RTMP or RTMPS. Whether your current Larix version can play a bhajan video stored on your phone as that feed’s source is a separate question, and the official material reviewed does not confirm it.
Check that capability on your exact device, operating system and app version before you plan around it. The steps below cover the documented encoder connection, how to test a file-playback path if your app offers one, and what to do if it does not.
What Larix Broadcaster is documented to do
Softvelum describes Larix Broadcaster as an app for streaming live video and audio from a smartphone or tablet. Its documentation covers publishing a live feed using RTMP, including RTMPS support. That is not the same as confirming that the app can select a video from your camera roll and play it continuously into the encoder.
YouTube’s encoder workflow is straightforward in principle: create a live stream in YouTube Studio, then give the encoder the server URL and stream key shown in Live Control Room. YouTube states this in its guide to creating a live stream with an encoder. The URL routes the feed; the key authorises it. Neither credential changes what source Larix can capture.
Keep those two questions separate while planning: can Larix connect to YouTube, and can your build of Larix use the stored file you want to broadcast? A successful connection test answers only the first. For a channel that needs a prerecorded devotional programme rather than a camera view, the source question is the deciding one.
If the main aim is a repeating bhajan playlist rather than a one-off mobile broadcast, compare the requirements with this overview of tools for looping a YouTube music stream. It can help clarify whether you need mobile capture, file playout, or an always-on arrangement.
Confirm file-source support before configuring the event
Do this check before scheduling a stream or telling viewers when it will begin. The reviewed Broadcaster pages explain live capture and publishing, but do not establish a direct “choose a prerecorded file” source. That gap is not proof that no version can do it; it means you need confirmation for the particular app build and operating system you will use.
Open the current app and look for an explicitly documented media or file source, rather than assuming that a camera preview can be replaced with a video-player screen. Check Softvelum’s current product and setup documentation, the app’s current release notes or support material, and the device’s available input options. If an option appears, confirm what it actually sends: the file’s picture and soundtrack, a screen image, microphone audio, or some combination.
Write down the device model, operating system version and Larix version during this check. App behaviour can change between releases and platforms; a tutorial for another phone is not confirmation for yours. If the official material does not settle it, ask Softvelum support or perform a rehearsal using the same device and file you intend to use. Do not treat a menu item with an unclear label as a working file-playout path until the YouTube preview confirms both picture and sound.
Larix Screencaster is a separate Softvelum app that streams a device screen. It may be worth investigating if the bhajan video plays in another app, but screen streaming does not by itself guarantee that the other app’s sound will be captured. Softvelum documents platform-specific restrictions on capturing audio from other apps, so test both channels of output rather than relying on a picture-only preview.
A useful decision rule is simple: if you can identify and test a file source in your current Broadcaster build, proceed to a private rehearsal; if you cannot, do not build the event around an assumed capability. Move to a separately verified playout method instead.
Prepare YouTube Live and protect the stream key
Check channel eligibility well before the event. YouTube’s current guidance says a channel needs to be verified and have no live-streaming restrictions in the preceding 90 days. First-time activation can take up to 24 hours. Those are YouTube’s operating requirements, not a guarantee that any particular event or content will be approved; review the current eligibility guidance in your account.
In YouTube Studio, open Go Live and create or schedule a stream. Use the current server URL and stream key displayed in Live Control Room. If the stream is scheduled, make sure you know whether the final step is to start the encoder, click Go live in Studio, or both for the configuration you chose. YouTube’s preview should show an incoming feed before you make the programme public.
Treat the stream key like a password. Anyone who obtains it may be able to send a feed to the associated stream. Do not place it in a public post, screenshot, shared document or message to viewers. If you think it has been exposed, replace it in Studio and update the encoder destination before the next rehearsal.
For a first run, create an unlisted or private rehearsal rather than experimenting during a public devotional programme. Confirm that the intended account and stream are selected in Studio, and keep the Live Control Room open so you can see whether YouTube receives the feed. Read YouTube’s current instructions for the stream you create instead of reusing an old URL or key from another broadcast.
Configure Larix for RTMP or RTMPS
YouTube recommends RTMPS, the encrypted extension of RTMP. In Live Control Room, use the lock icon in the stream settings to reveal the RTMPS server URL, then copy the exact current URL and stream key into Larix. YouTube explains the transport in its RTMPS encryption guidance. Prefer the endpoint Studio provides rather than copying an address from an old guide.
In Larix, create or edit a connection and enter the server/application path and stream key in the fields the app provides. Follow Larix’s current instructions for how its connection URL is assembled; do not assume that the key belongs in a particular field if your version presents a different layout. Confirm that the publishing mode carries both video and audio. Softvelum’s YouTube example uses video-and-audio mode because YouTube does not accept a video-only or audio-only feed in that setup.
YouTube’s current encoder settings guidance lists H.264, H.265/HEVC and AV1 video options, frame rates up to 60 fps, CBR bitrate encoding, AAC or MP3 audio, and a recommended two-second keyframe interval with a four-second maximum. These are platform settings, not a reason to push a mobile device to its highest possible output. Choose settings supported by the encoder and connection, and validate them in a rehearsal. If Larix does not expose a setting or source mode you need, do not infer that the platform recommendation means your app can provide it.
After saving the connection, check every character of the URL and key before starting. A connection error may come from a mistyped destination or an expired key; it does not demonstrate that the file source works. If you need help diagnosing a changed credential, this guide on reconnecting after a YouTube stream key expires covers the separate connection issue.
Test the prerecorded playback path if your build supports it
Only continue on this path if your current app and device offer a source that you have verified can send the stored bhajan file. First use a short, non-public rehearsal with the actual file. Start the file in the way the app requires, start Larix publishing, and watch the YouTube preview. Confirm that it is the intended video, that the audio is the file’s soundtrack rather than room sound, and that the picture and sound continue together.
Test the controls you would need during a real programme. Check what happens if the phone locks, the display changes orientation, a notification arrives, the file reaches its end, or the playback app is interrupted. These behaviours are device- and app-dependent; no general Larix file-playback recipe should be inferred from the RTMP setup. Do not assume a video will repeat, that playback continues in the background, or that the stream reconnects into the same programme without checking.
If your proposed method uses screen capture, test that separately from direct file input. Confirm that the captured image is not obscured by controls or notifications and that the soundtrack is present. Some mobile operating systems or apps restrict capturing another app’s audio. A microphone picking up the phone speaker is not equivalent to clean playback audio and can introduce room noise or echo.
Keep the rehearsal private or unlisted and ask another person to view it from a different device. A preview on the broadcasting phone alone may not reveal how the public watch page behaves. Verify the image and sound from a viewer’s perspective, then repeat any step that was inconsistent before committing to the live programme.
If the source cannot be made reliable during the test, stop there. A stable RTMP connection does not repair a missing or intermittent file feed. Switch to a different, tested playout workflow rather than leaving a public event dependent on an unconfirmed input.
Check picture, sound and stream output
A bhajan broadcast needs intelligible, steady audio as well as a visible picture. Listen to the YouTube preview and the watch page on a second device at a comfortable listening level. Check that the opening is not silent, the music is not distorted, and any spoken introduction remains audible. Do not rely only on the phone’s own speaker, which may hide a routing or capture problem.
Watch for sync drift, black frames, frozen images, abrupt changes in orientation and unexpected overlays. If the video file contains its own soundtrack, make sure you are not also capturing a microphone or other app audio unless that is intended. A recording that sounds right locally may be muted or altered in the outgoing feed because of the way the device captures playback.
YouTube recommends testing and previewing before going live, then monitoring audio and video during the broadcast. Keep Studio available, and ask a moderator or trusted viewer to report problems from the watch page. For a practical checklist focused on a common failure, see why an Indian music stream may have no sound.
Also test what happens when your internet connection changes. A mobile connection can fluctuate, and high output settings may be harder to sustain than a modest test configuration. Use an available stable connection where possible, observe YouTube’s incoming status, and lower output settings if the encoder or network cannot maintain the feed. Do not treat a successful start as proof that the stream will remain healthy unattended.
Before the event, check the opening and ending of the actual file and confirm that you have rights to stream the recording and the underlying musical composition. YouTube’s live streaming policies require live content to follow its Community Guidelines and Terms of Service. They do not establish that you have permission to broadcast a particular bhajan. Check the rights applicable to both the composition and the sound recording, and use media you own or are authorised to stream.
Choose a different workflow if Larix cannot play the file
If direct file playback is unavailable or unverified, choose a workflow that explicitly supports the source you need. That might mean another encoder or playout arrangement that can take a stored video as input, but its compatibility, operating requirements and reconnect behaviour still need to be checked independently. Do not assume a tool’s ability to publish to YouTube proves that it can loop or play your file.
A mobile screen-capture workflow is a possible experiment, not a guaranteed substitute. Larix Screencaster is distinct from Broadcaster, and audio capture from other apps can be restricted. If you test it, verify the picture and soundtrack on an unlisted stream using the target device and playback app. If the sound is absent or unreliable, the workflow is not suitable for the programme as configured.
For a longer-running channel, a phone-based live capture workflow also has practical limits: the source device must keep the relevant app and connection functioning, and someone needs a plan to notice and respond to interruption. Compare that with an encoder or managed playout arrangement designed for prerecorded media. The right choice depends on whether you need a single scheduled programme, a repeating playlist or an unattended channel; each requires its own rehearsal and monitoring plan.
If your real requirement is an ongoing file-based channel, this guide to a pre-recorded bhajan live-streaming setup for a devotional channel in India explores that broader decision. For comparison, StreamNeo removes the need to keep your own computer running by taking an uploaded video and broadcasting it to YouTube, but it is YouTube-only and does not establish that Larix can play a local file.
End a rehearsal by stopping the encoder and ending the test stream in Studio. For a public broadcast, monitor it while live, stop the encoder when the programme is finished and end the stream in Live Control Room. YouTube says streams under 12 hours are automatically archived; check the current Studio state and archive after the event rather than assuming a local recording exists.
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 stream a prerecorded bhajan file directly?
The reviewed official Broadcaster materials document live capture and RTMP/RTMPS publishing, but do not confirm direct selection and playback of a stored video file. Check the current app version and operating system, then test the exact file and output before relying on it.
Is Larix Broadcaster the same as Larix Screencaster?
No. They are separately named apps, and screen streaming does not guarantee that audio from the playback app will be captured. Verify both picture and sound in a private rehearsal on your device.
Should I use RTMP or RTMPS for YouTube?
Use the current RTMPS destination from YouTube Studio where your encoder supports it; YouTube recommends encrypted RTMPS transport. Copy the exact URL and stream key shown for your stream, and keep the key private.
What should I check before making the bhajan stream public?
Confirm YouTube channel eligibility, rights to the composition and recording, and a working preview with the intended picture and audible sound. Rehearse privately or unlisted, monitor from another device, and check YouTube’s current policies and settings.
