A free scan shows the junk files, broken settings and background clutter dragging Windows down - then fixes them in one click.Free scan · Windows 10 & 11To loop a prerecorded video on YouTube Live from Oracle Cloud, run FFmpeg on a compute instance with -stream_loop -1 before the input file, encode or copy the media into a YouTube-compatible stream, and send it to the RTMPS address and stream key shown in YouTube Live Control Room. The instance must stay running and have enough processing capacity and upload bandwidth; Oracle’s Always Free allowance does not guarantee available capacity or suitable encoding performance.
What this setup does—and what it does not do
This is a live-ingestion workflow: FFmpeg repeatedly reads a local prerecorded file and sends it to a YouTube Live event. It does not make an ordinary uploaded YouTube video repeat automatically. You need a channel eligible to stream live and an encoder connection to a stream configured in YouTube Live Control Room. YouTube says streams under 12 hours are automatically archived; that guidance does not establish what will happen to a single uninterrupted stream lasting longer than 12 hours. YouTube Help: Create a live stream with an encoder.
The broad sequence is: verify live access, create the event, prepare an Oracle Cloud Infrastructure (OCI) instance and media file, install and configure FFmpeg, run a short test, then monitor the stream. RTMPS is YouTube’s recommended general encoder connection; use the exact endpoint shown in Live Control Room rather than guessing its URL path. YouTube Help: Choose live encoder settings, bitrates, and resolutions.
1. Check YouTube access and create the live event
- Enable live streaming and check restrictions. Verify the channel can stream and has no live-streaming restriction in the preceding 90 days. Complete any account verification or activation steps YouTube displays before you plan a broadcast.
- Create or schedule the stream. In YouTube Studio, open Live Control Room and create or schedule an encoder stream. Use the live-stream configuration shown there; do not assume the settings for an uploaded video are the same.
- Copy the ingest details securely. Copy the RTMPS server URL and stream key from the event’s encoder settings. Treat the key like a password: anyone who obtains it may be able to broadcast to that event. Do not put it in a public script, repository, screenshot, or article.
YouTube recommends RTMPS, its encrypted extension of RTMP. The exact server URL and key are event-specific, so substitute the values supplied in Live Control Room. YouTube Help: encoder settings.

2. Prepare an Oracle Cloud instance and media file
Choose and check the instance
If you are relying on OCI Always Free compute, Oracle says eligible Always Free compute instances must be created in the tenancy’s home region. Oracle also lists 10 TB per month of outbound data transfer for Always Free resources. These allowances do not guarantee that a suitable shape is available, that your tenancy has capacity, or that a particular instance can encode your source reliably. Check the current console entitlements, capacity, tenancy limits, workload performance, and billing state before relying on the instance. Oracle Cloud Infrastructure: Always Free Resources.
For a sustained broadcast, the instance needs to read the full media file and keep up with the chosen video and audio encoding workload. Whether a CPU can do that depends on the source, encoder, resolution, frame rate, and settings; the Always Free allowance by itself says nothing about your encoding speed. Test the actual workload before depending on it.

Transfer the source file and protect credentials
Place the video somewhere the instance can read, such as its local disk, and confirm the available storage is sufficient. Use a private transfer method and restrict permissions on files containing the stream key. Avoid embedding the key directly in a command that could be retained in shell history or visible to other users on the instance. A protected configuration file or a carefully managed environment variable is safer; restrict access to it and do not print it in logs.
3. Install FFmpeg and choose compatible output settings
Install FFmpeg using the package manager for the operating system on your OCI instance, or use a trusted FFmpeg build appropriate to that system. Confirm it is available with ffmpeg -version. Package names and available encoder builds vary by operating system and repository, so use that system’s current package instructions rather than assuming one installation command fits every instance.

Choose the output codec, resolution, frame rate, bitrate, and keyframe interval to match YouTube’s current encoder guidance and your source. YouTube’s guidance gives recommended H.264 bitrates of 10 Mbps for 1080p at 30 fps and 17 Mbps for 1080p at 60 fps. It recommends CBR and a two-second keyframe interval, not exceeding four seconds. Those figures apply to the specified H.264 resolutions and frame rates; other resolutions and codecs have different recommendations. Check the current table before selecting settings. YouTube Help: encoder settings and bitrate table.
For file input, FFmpeg’s -re option reads at the input’s native frame rate, which is useful when packet timing should resemble a live feed. Do not apply it indiscriminately to a genuine live-capture input. Put -stream_loop -1 before the relevant -i; this tells FFmpeg to loop that input indefinitely. FFmpeg documentation.

4. Run FFmpeg with an infinite input loop
This illustrative command re-encodes the file to H.264 and AAC, outputs FLV for the RTMP-family ingest, and sends it to an RTMPS endpoint. It is a template, not a tested configuration; the sample bitrate and GOP are not universal recommendations.
ffmpeg -re -stream_loop -1 -i input.mp4
-c:v libx264 -preset veryfast -b:v 4500k -maxrate 4500k -bufsize 9000k
-pix_fmt yuv420p -g 60 -c:a aac -b:a 128k -f flv
'rtmps://YOUR_YOUTUBE_INGEST_URL/YOUR_STREAM_KEY'Replace input.mp4 with the media file’s path and the URL with the exact RTMPS URL and key from Live Control Room. Keep the real key private. FFmpeg documents the input-loop option, real-time input rate, RTMP-family protocols, and FLV streaming output. FFmpeg documentation.

Adjust the command to your source and target
- Bitrate: The sample’s 4500 kbps video bitrate is only an example. Set bitrate and output resolution/frame rate in line with YouTube’s current table and the bandwidth your connection can sustain. The cited 1080p H.264 recommendations are 10 Mbps at 30 fps and 17 Mbps at 60 fps; do not apply them to different codecs or resolutions as if they were universal.
- Keyframes:
-g 60means 60 frames per GOP. It corresponds to a two-second GOP only at 30 fps. At another frame rate, choose a GOP that gives the recommended two-second interval; keep the interval within YouTube’s stated maximum of four seconds. - Re-encode or copy: The example re-encodes video and audio. Re-encoding lets you select output settings but uses instance processing capacity. Stream copy can avoid encoding work when the source codecs and parameters are compatible with the chosen YouTube ingest settings, but it does not convert an incompatible source into a compatible one. Confirm the source format and test playback before depending on stream copy.
- Preset and pixel format:
veryfastandyuv420pare example x264 and pixel-format choices, not a guarantee that any instance can encode at the selected resolution and frame rate. Watch FFmpeg’s output for speed falling below real time or encoding errors. - Audio: The example encodes AAC at 128 kbps. Check that the file has the audio you intend to broadcast and verify it in YouTube’s preview; a silent source will not gain meaningful program audio by being encoded.
FFmpeg also supports FIFO output recovery options that can retry after certain temporary network failures. Treat that as optional hardening, not a guarantee of uninterrupted playback or a substitute for monitoring. FFmpeg format documentation.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.5. Test the stream before relying on it
- Start the command while the YouTube event is open in Live Control Room.
- Wait for the incoming stream preview and check that video, motion, and audio are present and correct.
- Check the stream-health indicators and the instance’s outbound bandwidth. YouTube recommends leaving 20% spare bandwidth, testing the stream, previewing it in Live Control Room, and monitoring stream health. YouTube Help: encoder settings and YouTube Help: streaming tips.
- Confirm FFmpeg can sustain the selected encoding settings without falling behind. Make changes and test again if the preview stutters, the health status degrades, or the instance cannot keep up.
Do not treat a successful connection as proof the stream will stay healthy indefinitely. For a long broadcast, plan how you will notice a stopped process, host interruption, lost network connection, or YouTube-side disconnect, and how you will restart or reconnect.
6. Troubleshoot common failures
- YouTube never receives the stream: Recheck that the event is open and the endpoint and key exactly match its Live Control Room settings. Ensure the instance has outbound network access. If the key has been exposed, replace it in YouTube and update the protected configuration.
- The connection is refused or drops repeatedly: Confirm you are using the provided RTMPS endpoint and not a guessed URL. Check instance networking and available upload bandwidth. A retry feature may help with temporary failures, but does not resolve a persistent network or configuration problem.
- Preview appears but playback stutters or stream health is poor: Check the uplink and leave the recommended bandwidth headroom. Reduce the target bitrate or output demand if the connection or instance cannot sustain the selected settings, then test again.
- FFmpeg falls behind or reports encoding errors: Verify that the file is readable and that the chosen codec is available in the installed FFmpeg build. Check whether CPU encoding can keep up; choose a less demanding output or a suitable hardware encoder if the instance supports one, then validate the result in Live Control Room.
- Video works but audio is absent or wrong: Inspect the source’s audio streams and check the audio codec and mapping. Confirm sound in the Live Control Room preview before relying on the event.
- The stream stops after a host or process interruption: Restarting FFmpeg may restore the encoder connection, but a host reboot, network outage, or YouTube event state may require separate recovery. Monitor the process and event, and test your restart procedure rather than assuming automatic recovery.
- You expect one archive from a stream longer than 12 hours: YouTube’s cited guidance promises automatic archiving for streams under 12 hours, not a single archive for a longer uninterrupted stream. Plan around that limit rather than relying on an unsupported archive outcome.
7. Check rights and channel-policy risks
Looping a file does not grant permission to broadcast its music, footage, narration, or other protected material. Use content you own or are authorized to stream, and check rights for every component, including background music. YouTube’s live-streaming access and content rules still apply to an encoder-based broadcast. A prerecorded loop also needs an editorial purpose and appropriate rights; automation does not exempt it from platform policies. Review YouTube’s current live-streaming requirements and policies before broadcasting. YouTube Help: live streaming.
Or let it run in the cloud
If you do not want to operate FFmpeg and an OCI instance, StreamNeo keeps an uploaded video or playlist live on YouTube from its cloud service: upload the recording, add your YouTube stream key, and go live. Nothing has to stay on at home, and the stream can continue with your computer off. It streams the upload as made, up to 4K 60fps, at one price per slot; it does not re-encode or use quality tiers. It also automatically recovers if YouTube drops the stream. The first day is free with no card; after that, the Monthly option is $9.99 per month. StreamNeo is for YouTube and uploaded videos, not live camera input. See StreamNeo, then start the free first day.
