Random freezes, missing sound and display glitches usually trace back to one bad driver. Find and replace yours safely.Free scan · under a minuteYou can use FFmpeg’s concat demuxer to play a compatible playlist of bhajans repeatedly into a live encoder output. For YouTube, that means preparing a manifest, supplying a continuous video picture if needed, pacing the input in real time, and sending it to the current RTMPS ingest address with your stream key. The loop repeats the playlist; it does not guarantee that your computer, internet connection, or YouTube event will stay live indefinitely.
What you need before you start
- FFmpeg installed on an always-on computer or server, with the required input and output support in its build.
- Bhajan files that you have permission to broadcast, and a manifest listing them in playback order.
- A stable upload connection with capacity for your chosen video and audio bitrates.
- A YouTube channel enabled for live streaming, plus the current server URL and stream key from YouTube Live Control Room.
- A still image or video to provide the picture if your live destination expects video. Audio-only acceptance depends on the destination and its current settings, so do not assume it will work.
Test the actual files, visual, output settings, network, and YouTube event before announcing a continuous broadcast. Keep the stream key private: treat it like a password, and do not put it in a public script, repository, or log.

Prepare the concat playlist
Create a UTF-8-compatible text file named bhajans.ffconcat. The first line identifies the concat format; each subsequent file line gives one track. For example:
Do these 3 things before closing this tab:
1Fix the driver behind crashes, sound loss and screen glitches2Repair Windows errors before they cause bigger problems3Scan for outdated or missing drivers - takes under a minuteffconcat version 1.0
file '/srv/media/bhajan-01.mp4'
file '/srv/media/bhajan-02.mp4'
file '/srv/media/bhajan-03.mp4'Use paths that exist on the machine running FFmpeg. Quote and escape paths correctly if they contain spaces or special characters. The concat demuxer expects the listed inputs to expose matching streams, including codecs and time bases. It uses file durations to place the next file, so inaccurate duration information can cause timestamp artifacts or trouble at transitions.

For a trusted local manifest with absolute paths, the example command below uses -safe 0 to permit those paths. Do not use that option blindly with an untrusted manifest: safe-path checks help prevent unwanted file access. If your files use paths accepted by the default safe mode, remove -safe 0.
Choose stream copy or normalization
Use compatible files for the simplest playlist
Stream copy avoids decoding and re-encoding the audio, reducing processing work. It is suitable only when the inputs are compatible with one another and their format is acceptable to the destination. A playlist that mixes incompatible codecs, stream layouts, or time bases can fail or produce glitches.
Normalize files that do not match
If the tracks are inconsistent, normalize them in advance to a common audio codec, sample rate, channel layout, and container, then list the normalized files. The appropriate settings depend on your source material and destination; there is no universally best preset. When inputs need to be joined with re-encoding, FFmpeg’s concat filter is the alternative to the concat demuxer. It requires a filter graph and more encoding work, so validate the result before using it for a long broadcast.
Run a looping playlist with a continuous picture
This starting pattern uses a local still image for video and loops the audio playlist. It encodes the picture as H.264 and the audio as AAC, then sends the output in FLV format to an RTMP-family endpoint. Replace the image path and destination placeholders; use the exact ingest URL and key supplied by your platform.

The sample video bitrate is only an example, not a recommended YouTube setting for every resolution or connection.- The example’s 128 kbps AAC stereo audio and 44.1 kHz sample rate are conservative starting values, not a substitute for checking the destination’s current requirements and monitoring stream health.
This is an illustrative command, not a tested universal configuration. Confirm that the installed FFmpeg build accepts the options and that the destination receives valid audio and video. For a moving visual, use a looped video input or a suitable filter graph, and validate that it remains available as long as the audio. Do not put an actual stream key in a public command transcript.
Configure the YouTube live destination
Use the current ingest details
In YouTube Live Control Room, create or select the live event and copy its current server URL and stream key into the encoder destination. YouTube recommends RTMPS, the secure form of the RTMP streaming protocol. If credentials are changed or an event is reset, update the encoder with the current values rather than relying on an old saved endpoint.
Match encoder settings to the event and connection
YouTube’s current encoder guidance lists H.264, H.265, or AV1 video, up to 60 fps, constant bitrate (CBR), AAC or MP3 audio for RTMP/RTMPS, and a recommended two-second keyframe interval that should not exceed four seconds. Its advanced guidance includes 44.1 kHz stereo audio and 128 kbps stereo audio. Use settings appropriate to the selected resolution, account setup, FFmpeg build, and available upload capacity; a bitrate shown for one resolution should not be copied automatically to another.
YouTube’s encoder setup says streams under 12 hours are automatically archived. That does not establish that a single 24-hour event is supported indefinitely, or how completely a 24/7 broadcast will be archived. Plan and verify the event behavior in YouTube’s current controls instead of treating an endless FFmpeg loop as proof that one YouTube event can run forever.

Use HLS only when your workflow calls for it
RTMPS is the straightforward choice for this basic FFmpeg pattern. YouTube also documents HLS ingest for some use cases, but it is a segment-based workflow with higher latency than RTMP. The documented requirements include HTTPS, TS segments, segments of 1–4 seconds, and a rolling playlist with no more than five outstanding segments. HLS therefore needs suitable packaging; it is not a drop-in replacement for the example’s RTMPS output.
Preflight, monitor, and plan recovery
- Run the complete playlist before going public. Check that every track opens, transitions cleanly, and produces the intended audio and picture.
- Check YouTube’s stream-health messages. Confirm that the event receives the expected audio and video and review warnings before promoting the stream.
- Leave bandwidth headroom. YouTube recommends that total streaming bitrate fit within upload capacity with 20% headroom. A disruption in connectivity can break the stream.
- Watch the host as well as the event. Monitor the FFmpeg process, output, host load, storage, and network. A restart policy and remote monitoring can help identify or recover from some failures, but they cannot guarantee uninterrupted service.
- Keep a recovery plan. FFmpeg documentation includes an RTMP FIFO output pattern that attempts recovery after temporary output errors. Such recovery does not fix a power loss, reboot, disk failure, expired credentials, persistent network fault, or platform-side termination.
Common FFmpeg concat and live-stream problems
The playlist fails to open
Check the manifest’s first line, file paths, permissions, quoting, and whether the files are available to the FFmpeg process. If you used absolute paths rejected by safe-path checks, only disable those checks for a manifest you trust.
Audio clicks, gaps, or timestamp errors at a transition
Confirm that the input streams match in codec and time base, and inspect duration metadata for inaccurate values. If tracks differ, normalize them before concatenating or use a concat-filter workflow that re-encodes them.
The stream ends when a track or visual ends
Verify that -stream_loop -1 is applied to the concat input and that the visual input is designed to remain available. Avoid relying on a finite image/video duration or -shortest without validating its interaction with the inputs.

YouTube reports unstable or insufficient input
Check actual upload capacity, reduce output bitrate if needed, and preserve the recommended 20% headroom. Verify the selected resolution and frame rate, then inspect YouTube’s health messages for encoder or network problems.
The server rejects the output
Recheck the current ingest URL and key, transport, container, codecs, keyframe interval, and event settings. A key copied from another event or a stale saved URL may no longer be valid.
FFmpeg stops after a disconnection
Review FFmpeg’s error output and YouTube’s event status. An RTMP FIFO recovery configuration can address some temporary output failures; use the options in the current FFmpeg documentation and test them with your build. For recurring failures, investigate the host, network, credentials, and event rather than assuming retries make the setup fault-proof.

Rights and continuous-play considerations
Use recordings and compositions for which you have the necessary permissions to broadcast and livestream. A bhajan’s devotional subject, traditional status, or availability online does not by itself establish that the composition or the particular recording is cleared. The rights status of any specific track depends on the work, recording, permissions, and relevant circumstances; no particular song or recording can be assumed safe here.

A playlist that loops forever is an encoder behavior, not a promise of 24/7 service. The machine must stay powered, FFmpeg must keep running, the connection must remain available, and YouTube must continue accepting the event. YouTube’s under-12-hour archive guidance is not evidence of indefinite event support or full archiving for a 24/7 stream.

Cost and operating trade-offs
FFmpeg is free software, but a self-hosted stream still depends on the cost and reliability of the always-on computer or server, electricity, network service, storage, and the time needed to monitor and recover it. A VPS or dedicated host can move the machine off-site, but check its compute, storage, data-transfer charges, restart options, and provider terms before relying on it; suitability varies by provider. StreamNeo instead charges per slot and includes cloud playback and the listed storage and support. Compare the operational responsibilities as well as the price when choosing.
