1Repair Windows errors before they cause bigger problems2Scan for outdated or missing drivers - takes under a minute3Clear out junk files and repair common Windows errorsFor a fixed prerecorded feed, FFmpeg is usually the simpler Linux choice: it can loop a file indefinitely from the command line. Choose OBS instead when you need a visual scene, multiple sources, overlays, previews, or hands-on controls. Neither program guarantees uninterrupted streaming by itself; the host, network, process recovery, media, and YouTube event setup all matter.
Choose by how you need to operate the stream
| Need | Better fit | Why |
|---|---|---|
| One or more prerecorded files sent in a repeatable, unattended pipeline | FFmpeg | Its -stream_loop -1 input option loops a source indefinitely, and it can be run as a supervised command-line process. [FFmpeg documentation] |
| A composed program with scenes, multiple visual or audio sources, overlays, or operator previews | OBS | Its visual production workflow makes it easier to compose and operate a live scene. OBS also documents reconnect behavior for supported outputs. [OBS output reference] |
| A continuous feed without maintaining a Linux machine at home | StreamNeo | It runs prerecorded YouTube streams in the cloud, at any uploaded quality up to 4K 60fps for one flat price per slot, with the first day free. |
This is a workflow recommendation, not a claim based on comparative uptime testing. A file loop, reconnect setting, and running process cannot by themselves ensure that YouTube keeps the same broadcast live or that a failed computer comes back online.

What you need before configuring either encoder
- A YouTube channel eligible to create live streams and access to YouTube Studio.
- The video and audio files you intend to play, checked for their actual codecs, frame rate, resolution, audio, and behavior at the end-to-start loop boundary.
- A Linux host with sufficient resources for the selected encoder, output quality, and workload. OBS lists OpenGL 3.3 compatibility and X Window System or Wayland for Linux/Unix, but warns that actual CPU demands vary with encoder, resolution, FPS, and scene complexity; compatibility alone does not guarantee streaming or recording capability. [OBS system requirements]
- A stable upload connection with headroom for the chosen video and audio bitrate, plus a way to monitor the process and recover it after a host or process failure.
- A plan for the YouTube broadcast event and for any complete recording you need. YouTube says streams under 12 hours are automatically archived; its help page does not promise an automatic archive for longer continuous streams. [YouTube Help: Create a live stream with an encoder]
Set YouTube’s ingest settings to match your stream
YouTube supports RTMP and RTMPS ingest, and lists H.264, H.265/HEVC, and AV1 video with AAC or MP3 audio. It recommends CBR and a 2-second keyframe interval, which should not exceed 4 seconds. YouTube recommends RTMPS for an encrypted connection. Use the current YouTube encoder settings for the full codec and resolution table; these are recommendations, not a guarantee that every encoder build or account accepts every combination.

| H.264 output example | YouTube recommended video bitrate |
|---|---|
| 1080p at 30 fps | 10 Mbps |
| 1080p at 60 fps | 12 Mbps |
Those two figures are YouTube’s recommendations; other frame rates, resolutions, codecs, and audio settings have separate values in its table. YouTube recommends automatic resolution and frame-rate detection by default. Choose the output to suit the source and your available upload bandwidth rather than assuming that a higher setting is automatically better.

Keep the stream key private
Create or schedule a live stream in YouTube Studio, then provide the encoder with YouTube’s server URL and stream key. Treat the key like a password: do not publish it in a command, screenshot, shared log, or public repository. If it is exposed, replace it in YouTube Studio and update the encoder configuration. A scheduled workflow lets viewers get reminders; YouTube’s documented process has the encoder start sending content and the operator click Go Live after the preview appears. [YouTube Help]
Run a prerecorded loop with FFmpeg
FFmpeg’s -stream_loop is an input option. Put it before the corresponding -i; -1 means infinite looping. [FFmpeg documentation]
Rank #2
- 【1080P HD High Quality】Capture resolution up to 1080p for video source and it is ideal for all HDMI devices such as PS4, PS3, Xbox One, Xbox 360, Wii U, DVDs, DSLR, Camera, Security Camera and set top box.

- 【Support Mic-in for Commentary】Rybozen capture card has microphone input and you can use it to add external commentary when playing a game. Please note: it only accepts 3.5mm TRS standard microphone headset.
- Inspect the source and your FFmpeg build. Confirm the file’s video and audio codecs, resolution, frame rate, duration, and whether your FFmpeg build includes the encoders you plan to use. Test the actual file at the loop boundary; a discontinuity, silence, or incompatible stream can be visible even when looping works as configured.
- Create the YouTube event. In YouTube Studio, create or schedule the stream and obtain its server URL and stream key. Use RTMPS where the encoder and endpoint support it.
- Choose output encoding. Configure the video codec, resolution, frame rate, CBR bitrate, and 2-second keyframes to match YouTube’s current settings. Configure AAC or MP3 audio and an appropriate audio bitrate. A stream-copy approach may avoid encoding, but only use it if the source’s codecs, timestamps, and parameters are accepted by the chosen ingest; otherwise transcode and test.
- Place the loop option before the input and send to YouTube. The command structure is
ffmpeg -re -stream_loop -1 -i "video.mp4" -f flv "rtmps://SERVER/APP/STREAM_KEY". Replace the bracketed options and endpoint with values matching your file, FFmpeg build, and YouTube Studio. This is a structural example, not a universal production command: protocols, codec support, stream-copy eligibility, and account ingest requirements vary. Keep the key out of public logs and files. - Test before leaving it unattended. Confirm YouTube receives a stable preview and audio, start the broadcast using the Studio workflow if required, and observe at least one full file loop. Verify the restart and reconnection behavior you intend to rely on instead of assuming the encoder will recover every failure.
- Supervise the process and host. Run FFmpeg under a service manager or other process supervisor configured for your Linux distribution so a process exit can be detected and restarted. Monitoring and restart policy are separate from FFmpeg’s loop option; a host shutdown, network outage, expired or invalid key, or ended YouTube event still needs its own recovery path.
The command-line example leaves encoding options abstract on purpose: a correct bitrate and codec combination depends on the source, FFmpeg build, desired output, and YouTube’s current settings. Validate the exact command with your own files and account before relying on it continuously.
Build and reconnect a prerecorded scene in OBS
- Install OBS for your Linux distribution and verify the graphics environment. Meet the listed OpenGL 3.3 and X Window System or Wayland requirements, then test the actual CPU or hardware-encoder load at the output resolution and frame rate you intend to use. [OBS system requirements]
- Make a scene for the prerecorded source. Add the media as a source, arrange any overlays or additional audio/video sources, and verify what happens when playback reaches the end. Configure looping for the media source if the chosen source and OBS version expose that control; test several loop boundaries and check audio synchronization.
- Set the output and stream destination. In OBS, open Settings and configure the stream service/server and stream key from YouTube Studio. Set the video and audio output to YouTube-compatible codecs, CBR, a 2-second keyframe interval, and bitrate appropriate to resolution and frame rate. Use YouTube’s current encoder table rather than carrying over settings from a different resolution or codec.
- Enable and test reconnect behavior. OBS documents reconnect settings for supported outputs, including a starting retry interval and maximum retry count; the retry interval doubles with each attempt to avoid overloading services. Confirm the available controls in your installed version and test recovery. Reconnect is not a guarantee that YouTube preserves the same event, and it does not restart OBS after the host or application itself fails. [OBS output reference]
- Preview, go live, and monitor. Confirm the YouTube preview, audio, scene transitions, and loop behavior before leaving the stream unattended. If you use a scheduled event, follow YouTube Studio’s preview and Go Live steps. Plan separate monitoring and recovery for OBS exits, Linux restarts, network loss, and the YouTube event state.
OBS is more convenient than a command line when you need to see and operate the composition. It still requires an available Linux host and enough real-world capacity for its encoding and scene workload.

Understand the YouTube broadcast and archive separately
YouTube treats encoder delivery settings and the viewer-facing event as distinct objects: a liveStream represents transmission settings, while a liveBroadcast represents an individual watchable event or video. The distinction matters if you want a 24/7 feed and separate event videos, such as an interview that starts and ends independently of the continuous channel feed. Google documents an API example of that pattern; API automation is an advanced route, not a requirement for a basic encoder setup. [YouTube Live Streaming API: broadcasts]
Stop sending content when you want to end the stream, and verify the event’s state in Studio. If a complete replay is important, do not rely on an automatic archive for a broadcast lasting 12 hours or more: YouTube documents automatic archiving for streams under 12 hours, but does not promise it for longer continuous streams. Arrange a separate local or other recording workflow and test its storage and recovery.

Common failures and practical fixes
| Symptom | Likely checks and fix |
|---|---|
| YouTube receives no signal | Check the server URL and stream key in Studio, whether the event is ready to receive the encoder, and whether the endpoint expects RTMP or RTMPS. Replace a key that may have been exposed. Check the encoder log for connection or protocol errors. |
| Preview appears but YouTube reports an encoding problem | Compare codec, resolution, frame rate, bitrate mode, keyframe interval, and audio format against YouTube’s current encoder settings. Confirm FFmpeg actually has the requested encoder, or that OBS is using the intended output profile. |
| Video stutters or drops frames | Check whether the machine is overloaded by encoding or OBS scenes, and whether upload bandwidth is stable at the configured bitrate plus audio. Reduce output demands or use a suitable hardware encoder only after testing the resulting stream. |
| Audio is missing, out of sync, or cuts at the loop point | Inspect the source’s audio stream and timestamps, test the file boundary, and verify the output audio codec and sample configuration. Re-encode when stream copy or source timing produces incompatible output. |
| Stream disconnects and does not return | Check the network, key, endpoint, event state, and encoder logs. OBS’s reconnect feature applies to supported outputs but does not recover a dead host or guarantee a live YouTube event. For FFmpeg, use external process supervision and verify that restarting the process can rejoin the intended event. |
| The stream ends, but the expected full replay is missing | Check the broadcast duration. YouTube says streams under 12 hours are automatically archived; for longer continuous feeds, use a separate recording plan if a complete archive matters. |
Cost and operational trade-offs
With OBS or FFmpeg, the software is only one part of the operating cost. You also need a Linux computer kept on, electricity, a reliable connection, sufficient encoding capacity, and a way to monitor and recover failures. OBS’s compatibility requirements are a starting point, not a performance guarantee; workload depends on encoder, resolution, frame rate, and scene complexity. A Linux mini PC or small-form-factor computer may suit a dedicated host, but the right hardware tier depends on the actual workload.
