A continuous YouTube stream on an AWS Lightsail VPS uses the VPS as a software-encoder host. The instance reads a video or generated feed and sends it to YouTube through the ingest URL and stream key.
This arrangement can keep your own computer switched off, but it does not guarantee uninterrupted streaming. You still need to check YouTube access, secure the instance, test the encoder, monitor the broadcast and plan what happens after a process, network or account failure.
Confirm YouTube Live access and choose a stream
Start in YouTube rather than AWS. YouTube requires the channel to be verified, live streaming to be enabled and free of a live-streaming restriction in the previous 90 days. For a channel enabling Live for the first time, activation may take up to 24 hours. Check the current requirements in YouTube's live-streaming eligibility guidance before planning a launch date.
In YouTube Studio, open Create, then Go Live, and select Stream. You can create a new stream or reuse an existing setup. Give the event a clear name, select the intended privacy setting and note whether the stream will start manually or use the relevant automatic behaviour available in your account.
The Live Control Room provides two separate pieces of information for an encoder:
- The stream URL, which identifies YouTube's ingest endpoint.
- The stream key, which authorises the encoder to send to the selected stream.
The key is a credential, not a label. Treat it like a password. Do not place it in a public Git repository, a screenshot, a shared document, a world-readable configuration file or a command copied into a public support forum. YouTube explains how stream keys and encoder settings work in its encoder setup documentation.
If you think the key has been exposed, reset it in Live Control Room and update the encoder. A reset can interrupt a running broadcast, so record the change in your operating notes and confirm that the new key is in the service configuration before restarting the process.
Choose a stream that matches the content you are actually sending. A devotional loop, a rain-and-lofi station and a local information loop may all use the same VPS pattern, but they have different audio, visual and recording needs. For an example of the media planning involved in a long-running audio-focused channel, see this 24/7 rain sounds and lofi radio setup.
Create and secure an AWS Lightsail Linux instance
In the AWS Lightsail console, create a Linux or Unix instance in a Region suitable for your administration and expected network path. An OS-only image is the straightforward choice when you intend to install and configure the encoder yourself. Choose the instance bundle only after considering two different loads: the CPU and memory needed to encode, and the outbound data transfer produced by the stream.
A prerecorded file still consumes CPU if the VPS is decoding and re-encoding it. A simple file that is already in a suitable format may use less processing than a source that needs scaling, frame-rate conversion, filters or several audio operations. Do not assume that a bundle which can run the operating system will also encode your chosen resolution and bitrate comfortably.
Lightsail offers browser-based SSH access, which is useful for initial administration. A static IPv4 address can be useful when you need a stable address for administration or DNS. It is not the YouTube stream key and it does not need to be part of the YouTube ingest configuration.
Review both IPv4 and IPv6 firewall settings. Lightsail documents these as separate rule sets. For a basic Linux instance, commonly present inbound rules may include SSH, HTTP and HTTPS. Remove rules you do not need, and restrict SSH to trusted addresses where practical. AWS describes the Lightsail firewall and its inbound rules.
For this push architecture, the encoder starts an outbound connection to YouTube. You do not need to expose an inbound RTMP or RTMPS listener on the instance merely because the VPS is sending a stream. Avoid adding ports by habit. Add an inbound rule only when you have identified a service that genuinely needs to receive connections.
The firewall is only one part of the security arrangement. Use a current Linux image, apply available package updates, avoid running the encoder as root and keep administrative access separate from the account used to run the media process. If you attach other services to the instance, review their authentication and logging separately.
Before committing to a bundle, read the current Lightsail pricing and bundle information for the selected Region. AWS allowances and charges can change, and outbound transfer for a continuous stream may be material. Do not use a price from an old tutorial as your cost estimate.
Connect to the instance and prepare the media source
Connect through Lightsail's browser SSH or another authorised SSH method, then create a dedicated directory for the source and service configuration. For example, you might keep a loop file below /srv/stream/, with logs and service files stored separately. The exact path is your choice, but consistent paths make restart procedures easier to document.
Install FFmpeg from trusted packages for the selected distribution or from an official build source. FFmpeg is an implementation choice for this setup, not a requirement imposed by YouTube. Check the installed build and its available protocols before relying on a particular command. The encoder must be able to open the supplied RTMPS endpoint and negotiate the required connection.
Copy the media file to the instance and check it before attempting a public broadcast. Confirm that it opens, has the expected duration, contains the intended audio tracks and does not stop at the first end-of-file. For a loop, FFmpeg needs an input option that repeats the file. A source with no audio also needs deliberate audio handling rather than an assumption that an audio track exists.
A useful preparation checklist is:
- The file is present at the path used by the service.
- The service account can read it.
- The disk has room for the source and logs.
- The source does not depend on a mounted laptop drive or temporary upload location.
- The output resolution and frame rate are known.
- The audio layout is known, including whether silence should be generated.
- The process will not write the stream key into its normal log output.
If the source is a set of clips rather than one prepared file, decide how the playlist should behave when one item is missing or fails. A single long file is easier to reason about, but it does not remove the need to monitor the encoder. If the source is a lecture or lesson, the problem of reaching the end of the input is especially important; this guide to preventing a 24/7 lecture stream from restarting covers the operational issue in a different setting.
Configure the software encoder with YouTube's URL and stream key
Use the exact ingest URL displayed for the selected stream. Prefer RTMPS when the encoder and the supplied endpoint support it. YouTube's current guidance should determine the codec, resolution, frame rate, bitrate, keyframe interval and audio settings. For H.264 1080p30, YouTube lists a recommended video bitrate range of 5 to 14 Mbps, while also recommending constant bitrate and a two-second keyframe interval. That is an encoder recommendation, not a promise that every Lightsail bundle can encode it.
The following is an illustrative FFmpeg pattern, not a tested command or a universal instance recommendation:
ffmpeg -re -stream_loop -1 -i /srv/stream/loop.mp4 \
-c:v libx264 -preset veryfast -pix_fmt yuv420p \
-r 30 -g 60 -b:v 5M -maxrate 5M -bufsize 10M \
-c:a aac -b:a 128k -ar 44100 \
-f flv "$YOUTUBE_INGEST_URL"
Adapt the input, codecs, bitrate, frame rate and complete ingest URL to the source and the current YouTube guidance. Confirm that the installed FFmpeg build supports the protocol and TLS features needed by the URL supplied in Live Control Room. If your source has no audio track, change the mapping or create the required audio deliberately rather than copying this command unchanged.
The -re option tells FFmpeg to read a file at approximately its normal playback rate. The loop option prevents a normal end-of-file from stopping the input. The video settings determine how much work the VPS must do. A slower preset may reduce CPU use at the cost of compression efficiency, while filters or scaling can increase the load.
Keep the URL and key out of the command history where possible. One approach is to place the complete destination in a root-readable environment or secrets file with restrictive permissions, then have the service read it. Check permissions with the chosen account and confirm that error logs do not print the credential. Do not put the key in a source file that will later be copied into a public repository.
For more detail on keyframe timing, see how often FFmpeg should send keyframes to YouTube. The important point is to align the encoder with YouTube's current requirements rather than treating one copied command as permanent.
Start the outbound stream and check YouTube's preview
Start the encoder manually during the first setup. Watch its output for input errors, permission failures, codec errors, connection failures and repeated reconnect messages. A process that remains visible in the terminal is not proof that YouTube is receiving a healthy broadcast.
Open the matching event in Live Control Room and wait for the incoming preview. Check that the preview shows the intended content, the audio meter behaves as expected and the event has the correct privacy and audience settings. Confirm that the preview belongs to the stream whose key you placed in the encoder.
Use a private or unlisted event for the first check if that suits your workflow. Do not make a public stream your only test of whether the source loops, the audio is present or the encoder can maintain its output. YouTube recommends previewing and checking stream health before and during a broadcast. Its live encoder settings and stream-health guidance should be the reference when the interface or available settings change.
Once the preview is correct, start the broadcast using the control shown for that event. Then watch the player from a separate device or network. Compare what you see in the player with the encoder logs and the Live Control Room status. This helps distinguish a local playback problem from an ingest or processing problem.
Keep the process running and monitor it
A terminal session is not a 24/7 operating plan. Run the encoder under a process supervisor such as systemd, with a dedicated non-root service account, an explicit working directory and logs that can be inspected without exposing the stream key.
A restart-on-failure policy is useful when FFmpeg exits because of a process error. It does not automatically solve every lost connection, and it does not protect against an instance failure, a full disk, a missing source file, an account restriction or a YouTube-side issue. If the encoder needs an explicit retry loop for failed connections, implement and validate that behaviour separately.
Define what you will monitor before leaving the stream unattended:
- Whether the encoder process is present.
- Whether its logs show repeated failures or a stalled input.
- Whether the instance has available disk space and acceptable CPU load.
- Whether YouTube reports an incoming signal and healthy stream.
- Whether the public player is still showing current content.
- Whether an alert reaches a person who can act on it.
Keep logs bounded so a long-running error does not fill the disk. Retain enough information to identify when the process stopped and why, but redact credentials. Write down the restart steps and keep a second administrative route available if your normal connection fails.
A managed workflow can remove the need to keep a personal computer running. For example, StreamNeo lets you upload the video once, provide the YouTube stream key and run the broadcast with monitoring and automatic process restarts, while leaving you responsible for the channel, content and YouTube settings. The Lightsail approach gives you more direct control, but also leaves the instance, encoder and recovery design in your hands.
Plan for network interruptions and recovery
The VPS sends data outward to YouTube, so the main network question is not whether viewers can connect to the instance. It is whether the instance can maintain its outbound connection to YouTube and whether the encoder responds sensibly when that connection disappears.
A short interruption may produce a reconnect attempt, an FFmpeg error or a stopped process, depending on the command and build. Do not infer the behaviour from the presence of a supervisor. Test the actual command with a non-public stream and observe what happens when the network path is interrupted, the process is terminated and the instance is rebooted.
Create a recovery checklist with these cases:
- FFmpeg exits. Check the last log lines, confirm the source still exists and restart the service if appropriate.
- The outbound connection fails. Check instance networking, the destination URL and YouTube stream status before repeatedly restarting.
- The instance reboots. Confirm the service is enabled to start at boot, then verify that the source is mounted and readable.
- The stream key changes. Update the protected configuration and restart the encoder deliberately.
- The source ends or becomes unreadable. Replace the file or correct the loop and permissions before returning to public streaming.
- YouTube reports a restriction or policy issue. Stop treating the problem as an infrastructure fault and review the official channel and stream guidance.
Also plan for recording. YouTube's automatic archive statement is limited to streams under 12 hours. A continuous 24/7 broadcast therefore needs a separate decision if preserving a complete recording matters. You could segment the broadcast into scheduled sessions, record a local copy with sufficient disk capacity or accept that a complete archive may not be available. Verify the current behaviour for your chosen stream configuration rather than assuming a long broadcast will become one complete video.
Finally, estimate transfer as bitrate multiplied by runtime, then compare that result with the allowance for the selected Lightsail bundle and Region. Include audio and protocol overhead in your planning. A higher bitrate can improve the picture but increases transfer use, and a heavier encoding profile can increase CPU load. Recheck AWS's current table and pricing calculator before choosing a production bundle.
Before committing, compare the operating options on the pricing page. When the file and channel are ready, start free — 24-hour trial, no card.
FAQ
Does a Lightsail public IP send the stream to YouTube?
No. The public IP is an address for the instance and may be useful for administration. The encoder sends to YouTube using the ingest URL and stream key shown in Live Control Room.
Do I need to open an inbound RTMP port?
Not for this push design. FFmpeg initiates an outbound connection to YouTube, so an inbound RTMP listener is not required. Keep only the inbound administration and application rules that you have a specific reason to expose.
Will systemd keep the YouTube stream running after every interruption?
It can restart a process that exits, but it cannot guarantee recovery from every network, instance, source, account or YouTube-side failure. Test the encoder's reconnect behaviour and pair process supervision with stream-health monitoring and an operator alert path.
Can YouTube archive a continuous 24/7 stream automatically?
YouTube's automatic-archive guidance is limited to streams under 12 hours. If a complete recording matters, use planned segments or a separate recording and retention process, then check the current official guidance for the stream configuration you use.
