You can run a prerecorded YouTube Live stream from a VPS by putting FFmpeg in a Docker container, connecting it to YouTube with the stream URL and key from YouTube Studio, and keeping the container running. The example below transcodes a local video to 1080p30 H.264 and loops it; it is an implementation pattern, not a universally tested command. Check it against your video, FFmpeg build, VPS, and current YouTube settings before relying on it.
What you need before you start
- A YouTube channel with live streaming enabled. YouTube says first-time enablement can take up to 24 hours.
- A VPS with Docker installed, enough sustained outbound bandwidth for your chosen stream, and storage for the video file.
- A prerecorded video file. This guide transcodes it to H.264; source codecs, dimensions, frame rate, audio, and installed FFmpeg build can require changes.
- A stream created or scheduled in YouTube Studio, with its server URL and stream key available.
YouTube’s encoder workflow is to create or schedule a stream in Live Control Room, configure an encoder with the server URL and key, start sending video, and check the preview. For a scheduled broadcast, start the encoder and wait for the preview before selecting Go live. See YouTube’s encoder setup instructions.
Choose the ingest protocol and output settings
Use RTMPS for an ordinary VPS-to-YouTube encoder connection. It encrypts the RTMP stream. Google’s RTMPS guidance specifies a valid RTMPS endpoint, port 443, and correct server hostname handling for SNI; preserve the hostname in the endpoint rather than substituting an IP address. See YouTube RTMPS ingestion guidance.
YouTube’s encoder settings support H.264, H.265 (HEVC), and AV1 video over RTMP/RTMPS, up to 60 fps, constant bitrate encoding, and AAC or MP3 audio. YouTube recommends a two-second keyframe interval and says not to exceed four seconds. Its advanced audio recommendations include 44.1 kHz stereo at 128 kbps; Rec. 709 is its SDR color recommendation. These are platform recommendations, not a guarantee that a particular input or FFmpeg build complies. Consult the current YouTube encoder settings and bitrate guidance.

These are YouTube’s published bitrate figures, accessed in 2026. Plan for outbound capacity above the selected video bitrate to allow for audio and protocol overhead and network variation. YouTube’s figures do not establish a universal VPS CPU or RAM size: transcoding is more demanding than passing through compatible encoded tracks, and the actual load depends on your file and output.
YouTube also lists HLS and DASH ingestion. They are encrypted and support different codecs, but segment-based delivery generally has higher latency than RTMP/RTMPS. For a straightforward prerecorded encoder feed, RTMPS is the practical default unless a codec or workflow calls for another protocol. The official ingestion protocol comparison describes the supported protocols and codecs.
Create the Docker image and protect the stream key
The following is a simple Debian-based container pattern that installs FFmpeg, reads a key from a mounted secret file, and starts a looping transcode. It is not a Docker or YouTube-prescribed configuration. Validate the package availability and command against your VPS, media, and installed FFmpeg version.

- Create a working directory on the VPS, for example
mkdir -p ~/yt-live/media ~/yt-live/secrets. Copy your video into~/yt-live/media/. - Save the stream key outside the image and repository. Create
~/yt-live/secrets/stream_keywith only the key in it, then restrict access:chmod 600 ~/yt-live/secrets/stream_key. Do not commit it, put it in a public Compose file or image, or expose it in screenshots, shell history, or logs. A Docker secret or your provider’s runtime secret facility is preferable where available. - Create a Dockerfile in
~/yt-live/:FROM debian:bookworm-slim RUN apt-get update && apt-get install -y --no-install-recommends ffmpeg ca-certificates && rm -rf /var/lib/apt/lists/* COPY start.sh /usr/local/bin/start.sh RUN chmod 755 /usr/local/bin/start.sh ENTRYPOINT ["/usr/local/bin/start.sh"] - Create the startup script as
~/yt-live/start.sh. SetYOUTUBE_RTMPS_URLat runtime to the complete RTMPS server URL issued by YouTube, including its application path but not the key. This script appends the mounted key as the final path component:#!/bin/sh set -eu : "${YOUTUBE_RTMPS_URL:?Set YOUTUBE_RTMPS_URL to the YouTube RTMPS server URL}" STREAM_KEY="$(cat /run/secrets/stream_key)" exec ffmpeg -hide_banner -nostdin -re -stream_loop -1 -i /media/video.mp4 -c:v libx264 -preset veryfast -pix_fmt yuv420p -r 30 -b:v 10M -minrate 10M -maxrate 10M -bufsize 20M -g 60 -keyint_min 60 -sc_threshold 0 -c:a aac -b:a 128k -ar 44100 -ac 2 -f flv "${YOUTUBE_RTMPS_URL%/}/${STREAM_KEY}"This example re-encodes to 1080p30 H.264 at YouTube’s 10 Mbps recommended video bitrate for that mode. A two-second keyframe interval at 30 fps is 60 frames, hence
-g 60. It assumes a usable audio stream. It does not scale arbitrary input to 1080p; inspect your file and add a suitable scale or frame-rate filter if needed. If the source already has compliant encoded tracks, stream-copying may reduce CPU use, but only when the codecs, frame rate, keyframes, audio, and bitrate are appropriate.Recommended Free Tools
Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy. - Build the image from that directory:
cd ~/yt-live && docker build -t yt-prerecorded:local .. - Start the container, replacing the example URL with the exact server URL from YouTube Studio:
docker run -d --name yt-prerecorded --restart unless-stopped -e YOUTUBE_RTMPS_URL='rtmps://YOUR-YOUTUBE-ENDPOINT/live2' --mount type=bind,src="$HOME/yt-live/media",dst=/media,readonly --mount type=bind,src="$HOME/yt-live/secrets/stream_key",dst=/run/secrets/stream_key,readonly yt-prerecorded:localKeep the endpoint hostname intact for TLS/SNI. Protect access to the Docker host and its configuration: anyone able to inspect a running container or its output may be able to access sensitive connection details.
Go live, monitor, and stop the stream
- Check that the container is running with
docker ps. View its output withdocker logs -f yt-prerecorded; do not share logs publicly without checking for credentials. - Open YouTube Studio’s Live Control Room and wait for the encoder preview. Check the picture, audio, and stream health before proceeding. For a scheduled stream, select Go live once the preview is available.
- Monitor both the YouTube health indicators and container output. The Live Streaming API documents health issues including low bitrate, frame-rate mismatch, and a missing audio stream: see the LiveStreams API reference.
- To stop the feed, stop the container with
docker stop yt-prerecorded, then use the relevant Live Control Room controls. YouTube says streams shorter than 12 hours are automatically archived when ended; that archive behavior is separate from Docker’s restart policy.
Choose the right repeat and recovery behavior
The sample uses FFmpeg’s -stream_loop -1 to repeat one file indefinitely while the process remains active. For a one-time scheduled broadcast, remove that option so the file ends after one pass. For a playlist or a schedule of different videos, use a deliberate playlist or scheduler rather than assuming that a container restart will produce the programming you intend.

--restart unless-stopped asks Docker to restart the container after an exit or host restart; it does not guarantee that YouTube accepts the reconnect or that the VPS itself remains available. Check the preview and logs after a restart. Keep YouTube’s 12-hour archive behavior distinct from your loop, schedule, and container policy.
Troubleshooting
No preview or connection timeout
- Check that live streaming is enabled and that the correct stream is selected in Live Control Room.
- Compare the configured server URL and key with the values for that stream. A wrong, revoked, or mismatched key prevents the encoder from connecting.
- Confirm outbound access to the RTMPS endpoint on port 443. Preserve the endpoint hostname so TLS/SNI can work.
- Check container output for connection errors and verify the VPS firewall or provider network rules.
SSL or certificate error
Confirm that the URL is an RTMPS endpoint rather than an RTMP address, uses port 443, and retains the valid endpoint hostname. Google’s RTMPS documentation identifies endpoint, protocol, port, and SNI handling as relevant connection requirements.

Picture but no sound
Check that the input actually contains an audio track and that the output maps and encodes it to a supported format. The sample assumes audio and encodes AAC stereo; adapt it for a silent video rather than relying on an audio mapping that does not exist. YouTube flags missing audio as a stream health issue.
The container exits when the video ends
With the sample’s loop option, a normal end of file should not finish the input; without it, the file plays once. Inspect docker logs yt-prerecorded for a decode error, missing file, or invalid command. A Docker restart policy restarts an exited process but does not itself decide whether to loop a file or schedule the next program.
Costs and ongoing responsibilities
Your VPS bill depends on the provider and plan; the YouTube encoder guidance does not specify a universal server size or hosting cost. Measure sustained outbound capacity against your chosen bitrate and overhead, then validate CPU and memory under the actual transcode workload. Stream-copying can reduce encoding load when the source is already suitable, while transcoding gives you more control over output but consumes compute.
