For a simple, fixed bhajan loop with a still image or uncomplicated visual, use Ubuntu Server 24.04 LTS on a dedicated host and FFmpeg. It avoids the desktop environment required for interactive production. Use OBS Studio if you need scenes, animated overlays, or hands-on control. Neither Ubuntu’s installation requirements nor OBS’s basic requirements guarantee that a particular machine can encode a reliable 24/7 stream; test the complete setup at the resolution and frame rate you intend to use.
Choose the setup that matches the stream
| Option | Best for | Trade-off |
|---|---|---|
| Ubuntu Server 24.04 LTS with FFmpeg | A fixed playlist or loop with a still image or simple visual. | A command-line workflow requires you to configure and monitor the process rather than manage it through a visual production interface. |
| Linux desktop with OBS Studio | Scenes, animated overlays, or interactive production. | OBS requires a graphical session and an OpenGL 3.3-compatible GPU; actual encoding needs depend on the encoder, resolution, frame rate, and scene complexity. Meeting the basic requirements does not ensure streaming performance. OBS Studio system requirements |
Ubuntu Server is the lighter starting point for a static devotional stream, not a promise that any low-powered computer will handle it. Canonical lists 1.5 GB minimum RAM and 5 GB minimum storage for an ISO installation; for cloud images, it lists 1 GB RAM and 4 GB storage. It suggests 3 GB or more RAM and 25 GB or more storage. Those figures describe OS installation, not FFmpeg encoding capacity, and Canonical notes that requirements vary by hardware, setup, and workload. Ubuntu Server installation requirements
Prepare the Linux host and media
1. Use a dedicated, stable machine
Install Ubuntu Server 24.04 LTS on a host that can remain powered on and connected to the internet. If you are buying hardware, treat a small-form-factor mini PC as a possible category, not a guaranteed solution: the machine’s suitability depends on the chosen encoder, visual workload, and settings. Keep the host in a ventilated place and avoid relying on a shared or unstable connection for a continuous broadcast.
2. Organize the audio and visual assets
Place the bhajan recordings and any accompanying image or visual in a stable location on the host. Decide how the tracks should repeat and whether the broadcast should show one still image or a simple visual. Check that the media plays as intended before configuring the live encoder. Use only music and imagery for which the channel has the necessary rights.

3. Install and configure FFmpeg
Use FFmpeg as the command-line encoder for a fixed loop. Choose an approach that repeats the intended audio and keeps the visual present for the broadcast. The exact command depends on the media files and how they are organized; the available platform guidance does not establish a single universally suitable loop command. Test playback and reconnect behavior before treating the host as unattended.
Set YouTube’s stream settings
Create the stream and protect its key
- Open YouTube Live Control Room and create or select the live stream.
- Copy the server URL and stream key into the encoder’s streaming configuration.
- Keep the stream key private. Anyone who obtains it may be able to send a feed to your stream.
- Choose RTMPS when configuring the encoder if available. YouTube recommends RTMPS, a secure extension to RTMP. YouTube encoder settings, bitrates, and resolutions
Use conservative video and audio settings
For a static image or uncomplicated visual, 720p at 30 fps using H.264 and a 3 Mbps video bitrate is a sensible starting point. For more visual detail, YouTube’s recommended H.264 bitrate at 1080p30 is 5 Mbps. These are YouTube recommendations, not universal minimums. The 1080p setting needs more sustained upload capacity; choose based on the host and connection rather than assuming higher resolution is always better.

| Setting | Starting point for a simple bhajan stream | YouTube guidance |
|---|---|---|
| Protocol | RTMPS | YouTube recommends RTMPS. |
| Video codec | H.264 | YouTube also lists H.265 and AV1 as options. |
| Resolution and frame rate | 720p30 for a still or simple visual | Up to 60 fps; select the resolution and frame rate the host can sustain. |
| Video rate control | CBR | YouTube lists CBR. |
| Keyframe interval | 2 seconds | Recommended interval; do not exceed 4 seconds. |
| Audio | AAC, stereo, 44.1 kHz, 128 kbps | YouTube lists AAC or MP3; for stereo AAC it lists 44.1 kHz and 128 kbps. |
For the platform’s codec, bitrate, and keyframe guidance, see YouTube’s encoder settings page. These recommendations can change, so consult the current guidance when configuring a new stream.
Check upload headroom at the streaming location
YouTube advises keeping 20% upload-bandwidth headroom beyond the total outgoing stream bitrate. Measure sustained upload performance where the Linux host will run, and account for other devices sharing that connection. A brief speed-test peak is not proof of a stable all-day connection. Network interruptions can affect reliability even when the encoder settings are correct. YouTube’s streaming tips also recommend monitoring the broadcast continuously.

Keep the stream running and protect archives
Plan recovery, not just process restart
You can configure a Linux process manager or service to restart FFmpeg after a process failure, but a restarted encoder is not automatically guaranteed to restore the YouTube live event. Test what happens after an encoder restart and a network interruption on the specific channel and setup. Confirm that YouTube receives the feed again rather than assuming a running FFmpeg process means viewers can see the stream.
Monitor the live output
- Check the public watch page, not only the encoder process.
- Listen for audio interruptions and watch for poor picture quality or a frozen image.
- Check that any local archive recording is being written and growing as expected.
- Recheck the stream after changes to media, network, encoder settings, or the host.
End events periodically if YouTube archives matter
YouTube says live streams shorter than 12 hours can be automatically archived, while streams longer than 12 hours may not be captured at all. Its guidance is: “If your live stream exceeds 12 hours, it may not be captured at all.” Keep a local archive backup and plan event endings if you need the YouTube archive.

Check music rights before going live
A devotional or religious purpose does not by itself establish permission to broadcast a recording. You need the rights required for the music and visuals in your live content. YouTube scans live streams for third-party content and may replace the stream image, interrupt the broadcast, or terminate it if it identifies material. If you have a licence for third-party content, YouTube says the rights holder may need to add your channel to its Content ID allowlist. Resolve permissions before starting the stream; do not assume that a recording is safe to use because it is already online. YouTube live-streaming terms and copyright guidance
Troubleshoot common failures
| Symptom | Likely cause | What to check |
|---|---|---|
| YouTube does not receive the encoder feed | Incorrect server URL or stream key, or a connection problem. | Verify the URL and key in Live Control Room and the encoder; confirm that the host can reach the internet. Keep the key private. |
| Stream drops or quality fluctuates | Insufficient sustained upload capacity, network disruption, or competing traffic. | Check the connection at the host’s location, leave YouTube’s recommended 20% headroom, and reduce bitrate or resolution if the connection cannot sustain the selected output. |
| Audio or image is missing or wrong | Media or encoder configuration does not match the intended loop. | Test the source files and local output before going live; check that the selected audio and visual remain present during playback. |
| FFmpeg restarts but the YouTube stream stays offline | Restarting the encoder does not necessarily restore the live event. | Test recovery with the channel and encoder. Verify the public watch page after a restart or network interruption. |
| Expected YouTube archive is absent or incomplete | A single event may exceed YouTube’s 12-hour archive behavior. | End events periodically when archives matter and keep a local recording. |
| Live stream is interrupted or replaced | YouTube may have detected third-party content. | Review music and visual rights, and ask the rights holder about Content ID allowlisting where applicable. |
