A Raspberry Pi 4 Model B is the sensible starting point for a modest 24/7 YouTube stream when you are encoding a live camera or scene. For a prerecorded video loop that is already encoded, the better low-power approach may be to copy the video and audio rather than encode them again.
The right choice depends more on the source and encoding path than on the board’s published power figure. Pi 4 can use hardware H.264 encoding in supported workflows, while Pi 5 uses software H.264 encoding, so you should assemble and measure the complete system rather than estimate a monthly bill from the board alone.
Choose between live capture and a prerecorded loop
Start by identifying what the Raspberry Pi is actually expected to do.
A live capture setup receives a camera feed, screen capture or another changing source. The Pi must capture the input, prepare the frames, encode them into a YouTube-compatible format and send the stream over the network. That makes the encoder and sustained CPU workload central to the decision.
A prerecorded loop is different. If your devotional video, bhajan programme, shop advert or ambience file is already encoded in a suitable format, FFmpeg may be able to read it and pass the existing audio and video through while rebuilding only the container or transport required for the broadcast. This is usually called stream-copy or remuxing. It avoids doing the same compression work again.
That distinction matters on a small computer. Re-encoding a long 1080p file continuously creates a sustained workload even though the visual content itself never changes. Stream-copying can be much lighter, but it is only appropriate when the source codecs, formats, timestamps and stream properties work with the rest of the pipeline.
For a camera-based devotional channel, local news loop with live inserts or small business feed, plan around capture and encoding. For a fixed playlist of finished programmes, test whether copying is suitable before buying a more powerful board. The workflow described in how to make a YouTube gaming livestream replay continuously is also useful as a reminder that looping and encoding are separate decisions.
YouTube’s current live guidance lists H.264 video, constant bitrate and a two-second keyframe interval, with the interval not exceeding four seconds. Its recommended H.264 bitrate examples are 5 Mbps for 1080p at 30 frames per second and 3 Mbps for 720p at 30 frames per second. These are ingestion recommendations, not proof that a particular Pi, storage device or internet connection can sustain the stream. Check the YouTube encoder settings guidance before choosing the final profile.
Compare the Pi 4 and Pi 5 encoding paths
The Raspberry Pi 4 Model B is the default choice when your live pipeline can use its hardware H.264 encoder. In supported camera and libav workflows, Raspberry Pi’s rpicam-vid documentation describes hardware H.264 encoding where that encoder is available. That can leave more general CPU capacity for capture, muxing, monitoring and network work.
This does not mean every FFmpeg command automatically uses the hardware encoder. The input method, installed packages, codec selection and pixel format all matter. You need to inspect the actual output and monitor the process rather than assume that the presence of a Pi 4 has solved encoding.
Pi 5 takes a different route for H.264. It does not have a hardware H.264 encoder. Raspberry Pi’s 2026 paper reports real-time 1080p30 software encoding under the paper’s tested settings, including a low-latency mode. That is useful evidence for a capable setup, but it is not a promise for every preset, bitrate, filter chain, camera format or surrounding workload.
Software encoding uses CPU resources continuously. A Pi 5 may be the better fit when you need more general processing capacity or when your chosen software-encoding settings have been validated, but it needs appropriate power and cooling for sustained work. A Pi 4 is usually the clearer first experiment when the objective is a modest H.264 stream with the lowest practical CPU burden.
| Choice | Encoding path | When it fits | What to verify |
|---|---|---|---|
| Raspberry Pi 4 Model B | Hardware H.264 in supported workflows | Live capture where hardware encoding is available, or a light stream-copy loop | Actual encoder selection, output profile, temperature and dropped frames |
| Raspberry Pi 5 | Software H.264 | A validated 1080p30 software pipeline or a workload needing additional CPU capacity | Preset, bitrate, CPU load, cooling, sustained behaviour and power at the wall |
| Either model | Stream-copy or remux where compatible | A prerecorded file whose existing streams are accepted by the pipeline | Codec compatibility, timestamps, keyframes, audio format and loop transitions |
The important comparison is not simply Pi 4 versus Pi 5. It is hardware encoding versus software encoding versus no re-encoding. Resolution, frame rate, bitrate, filters, audio processing and network conditions can change the result more than a board label suggests. For a broader look at bitrate decisions, see this guide to why a YouTube live stream can look blurry at high bitrate.
Gather the power supply and boot essentials
Use a power supply matched to the board. Raspberry Pi recommends a 5 V, 3 A, 15 W USB-C supply for Raspberry Pi 4. For Raspberry Pi 5, the official recommendation is the 27 W USB-C supply, with the documentation describing a 5 V, 5 A requirement for full peripheral capability.
Those are supply requirements, not a measurement of what the completed streaming system will consume. The board may be joined by a camera, USB storage, Ethernet hardware, cooling equipment, display adapters or other peripherals. Cable quality and voltage loss can also matter, particularly when a device is under sustained load.
Raspberry Pi’s documentation says, “We recommend using an official Raspberry Pi power supply.” That is a practical starting point for a channel intended to run unattended. A random phone charger may appear to work while the board is idle and then become unsuitable once encoding, storage and networking are active.
For boot media, a microSD card is the common simple choice. USB storage is also supported, but neither model includes onboard storage for your operating system and media. Keep the system image and the streamed files separate where practical. If the loop is large, storing it on reliable USB media can make replacement and migration easier, but introduce one change at a time during testing.
If you choose Pi 5 for sustained software encoding, treat cooling as part of the build rather than an optional decoration. The aim is not to chase a board temperature number in isolation. It is to prevent thermal behaviour from changing the encoder’s performance during a long run.
A small installation should also have a recovery plan. Label the power supply, board, storage and network cable. Keep a second boot image or a documented re-image procedure. If the channel matters to your business, make a copy of the configuration and the media file somewhere other than the device itself.
Use wired networking where practical
For a fixed streaming station, connect the Pi to the router by Ethernet when the room and installation allow it. Wired networking removes one variable from a system that already depends on a camera, storage, encoder and power supply. It does not guarantee a stable broadcast, but it gives you a more predictable local connection than relying on a marginal wireless signal.
Provision more upstream capacity than the configured stream bitrate and test the real connection at the installation point. A 5 Mbps video setting describes the stream payload, not every part of the connection. Protocol overhead, audio, other devices and fluctuations in the upstream path all need room.
Do not assume that a good download speed represents a good live upload path. Run the test at the time of day when the channel will operate, then leave the stream running long enough to observe network behaviour. There is no single India-wide ISP result that can be applied to every state, building or connection.
The router and modem deserve attention as well. If the Pi has backup power but the networking equipment does not, an outage can still stop the broadcast. Conversely, a backup supply sized only for the Pi may not support the complete network path for the required outage window. Measure and plan the connected equipment together.
Use RTMPS where your encoder supports it. YouTube describes RTMPS as the secure extension to RTMP in its official guidance. Keep the stream key private, enter it carefully and avoid placing it in shell history, public screenshots or shared configuration files.
Set up a lean Linux and FFmpeg workflow
Use a minimal Raspberry Pi OS or other suitable Linux installation rather than loading a desktop environment you do not need. A headless setup reduces the number of services and removes the temptation to use the Pi as a general-purpose computer while it is broadcasting.
Install only the capture, encoding, monitoring and administration tools required for the job. Keep the operating system and packages maintained, but schedule updates deliberately. An unattended update that changes the media stack immediately before a broadcast is not a useful experiment.
A sensible workflow has these stages:
- Capture the camera or read the media file.
- Select the intended resolution, frame rate, audio settings and bitrate.
- Encode with the appropriate hardware or software path, or copy compatible streams.
- Place the streams in the required container and send them to YouTube over RTMPS.
- Record useful logs and restart the process when it exits unexpectedly.
- Alert yourself when the process has stopped rather than relying on a viewer to notice.
For camera work, test the complete rpicam-vid or FFmpeg path with the same camera, cable and output settings you intend to use later. Raspberry Pi’s rpicam-vid documentation explains its libav route for saving or streaming media. Use the documented options as a starting point, then confirm what your installed version actually supports.
Run the streaming process under a supervisor or a service manager so it starts after boot and can be restarted after an ordinary process failure. A restart policy is not a substitute for diagnosis. If the process repeatedly fails because of an invalid input, full storage or a rejected format, automatic retries will only hide the cause.
Keep the command readable. Put sensitive values such as the stream key outside a script that is copied into public notes. Write down the chosen settings, input device, file path and recovery steps. Six months later, this record is often more useful than remembering that the original command once worked.
For a prerecorded channel, test one complete loop and the transition back to its beginning. Confirm that audio does not drift, the picture does not freeze at the join and FFmpeg does not gradually increase its memory use. If you are troubleshooting a black screen, this guide to fixing an FFmpeg YouTube stream black screen when looping videos covers a related failure mode.
Avoid re-encoding when stream-copy is suitable
Stream-copying means FFmpeg moves the compressed audio and video packets into a new output without decoding and compressing them again. It can be a strong fit for a finished video loop because the Pi is not asked to perform continuous video compression.
The limitation is compatibility. The source video must use a codec and properties accepted by the receiving pipeline. Its keyframes, timestamps, pixel format, audio codec and container behaviour must also fit the output. A file that plays in a desktop media player is not automatically a good source for a long live broadcast.
Start with a short test. Inspect the file, send a private or otherwise controlled test stream, and watch the YouTube health indicators and local logs. Look for frozen video, missing audio, timestamp warnings, unexpected reconnects and a loop transition that takes the stream offline.
If the source does not fit, you have choices. Re-encode the file once into a suitable format before putting it on the Pi. Re-encode continuously on the Pi if the content must change live. Or choose a different source file. Pre-converting a collection of finished programmes on a more capable computer can keep the always-on Pi’s job simple.
Do not force stream-copy merely to reduce CPU use. A stable, compatible encode is more valuable than a theoretically lighter command that produces invalid timestamps or an unreliable hand-off. The same principle applies to devotional playlists, rain sounds, shop adverts and local information loops.
A loop also needs a deliberate keyframe structure. YouTube’s two-second recommendation is relevant to the outgoing live stream, but copying a file does not give you permission to ignore the source’s timing. When the source cannot provide the access points and timestamps your output needs, a one-time conversion may be the cleaner solution.
This is where a cloud workflow can remove a particular operational burden: StreamNeo lets you upload the finished file once and run the YouTube broadcast without leaving your computer switched on, which is useful when the Pi would otherwise be used only to relay a completed loop. It remains YouTube-only, so confirm that this matches your channel plan.
Check stability and actual wall draw
A Raspberry Pi can stream to YouTube 24/7 in the sense that it can be configured to run continuously, but a configuration is not evidence of uninterrupted service. Before treating the channel as always-on, test the complete system for sustained operation and deliberately rehearse the failures that matter.
Unplug the network cable briefly and observe whether the process reconnects, exits or needs a manual restart. Test a router restart. Test a controlled power interruption. Check what happens when the Pi boots without the camera attached, when the media drive is slow to mount and when the stream key or input path is wrong. Record the result for each case.
Watch CPU use, memory use, temperature, encoder messages, dropped frames, network output and storage errors. YouTube’s dashboard can show stream health, but it does not replace local monitoring. A broadcast may still be running while frames are being dropped or the picture is arriving late.
Measure the assembled system at the wall with a suitable power meter. Include the Pi, power supply, camera, storage, cooling and any equipment that must remain powered for the broadcast. If the router and modem need backup during an outage, measure those as well.
Raspberry Pi documentation lists an approximate 600 mA typical active current for a bare Raspberry Pi 4 Model B under its stated conditions. The table notes that additional USB devices and HATs are not included. This is a reference point, not the wall consumption of a complete 24/7 streaming installation, and it should not be treated as evidence of reliability.
Once you have an average wall measurement, estimate energy for a 30-day month with:
average watts × 24 × 30 ÷ 1000 = kilowatt-hours per 30-day month
Then multiply the result by your applicable electricity tariff. Indian tariffs vary by state, distribution company and usage slab, so a single rupee figure would be misleading without your location and bill details. The meter reading is also more useful than a board-only estimate when you are deciding whether a different workflow is worth the effort.
For backup power, first decide the outage window you actually need. Measure the complete load, account for UPS efficiency and include the network equipment if the stream depends on it. Do not describe the result as uninterruptible until you have tested the exact arrangement under a realistic outage.

FAQ
Can a Raspberry Pi stream to YouTube 24/7?
It can be configured for continuous streaming, but the board alone does not establish continuous service. Test the complete camera or file workflow, network path, power arrangement and recovery behaviour before relying on it overnight or for a public channel.
Which Raspberry Pi is best for a 24/7 YouTube stream?
Pi 4 is the practical default for a modest live H.264 pipeline that can use supported hardware encoding. Pi 5 is worth considering when its tested software-encoding performance and additional CPU capacity suit your settings, but validate sustained load, cooling and power use first.
How much power does a Raspberry Pi use running all day?
Published board figures are only reference points and do not represent the assembled streaming setup. Measure the Pi, supply, camera, storage, cooling and network equipment at the wall, then use the measured average watts to calculate monthly kilowatt-hours.
Is stream-copy always better than encoding?
No. Stream-copy can reduce processing when an existing file is compatible with the output, but unsuitable codecs, timestamps or keyframes can cause failures. Test the complete loop and use a one-time conversion or continuous encoding when that produces the more dependable result.
