Do these 3 things before closing this tab:
1Clear out junk files and repair common Windows errors2Fix the driver behind crashes, sound loss and screen glitches3Repair Windows errors before they cause bigger problemsFor one 24/7 YouTube playlist made from already-encoded files, start by testing a Linux VPS with about 2 vCPU and 2–4 GB of RAM. That is a practical trial configuration, not a YouTube requirement or a guarantee: CPU sharing, codecs, resolution, frame rate, filters and concurrent jobs all affect resource use. If FFmpeg must encode or transcode continuously, size the server from a test of your actual command rather than assuming the same small VPS will keep up.
First decide what FFmpeg will do
The key sizing question is whether FFmpeg only loops and sends finished media, or also has to encode, transcode, scale, composite or filter it. A static loop of pre-encoded media can be much lighter on CPU than real-time encoding. The 2-vCPU, 2–4-GB starting point is an inference for a single lightweight stream, not a universal minimum. One current hosting-provider guide separately suggests that baseline for a static loop, but it is commercial provider guidance, not an independent benchmark (SpaceNode’s FFmpeg streaming guide).

Looping pre-encoded files
If the files already have the video and audio formats you intend to send, and the command packet-copies them without expensive filters or re-encoding, begin with the smaller trial tier. Check CPU use anyway: an unexpected encode, filter chain, or concurrent process can change the workload. Allow disk space for the media you keep on the VPS, the operating system, logs and temporary files; storage need depends on file sizes, not the outgoing stream bitrate.
Encoding, transcoding or filtering
Real-time encoding is a different sizing problem. FFmpeg’s reported processing speed needs to remain at or above 1x for the stream to keep pace; sustained speed below that means it is falling behind. Resolution, frame rate, codec, preset, scene detail, filters and parallel encodes can all change CPU demand. Google’s VP9 guide illustrates this workload sensitivity with a tested quad-core desktop configuration in which some 2160p and 1440p settings fell below real time; those results do not predict performance on every VPS or codec (Google’s VP9 encoding guide).
#1 Best Overall
For heavier jobs, assess sustained CPU performance with representative media and the exact command. Hetzner describes shared CPU resources as suited to variable usage and dedicated vCPUs as appropriate for constantly high CPU use (Hetzner Cloud plans). AWS’s 2024 benchmark used FFmpeg 6.0 with particular x264 and x265 workloads, instances and output resolutions; its results support evaluating accelerator or larger compute for substantial multi-resolution transcoding, not assuming that a GPU VPS is cost-effective for one pre-encoded loop. AWS also advises validating results for the intended workload (AWS’s FFmpeg benchmarking article).
Set the stream target and budget its bandwidth
YouTube’s ingest recommendations describe the video stream sent to YouTube; they do not specify how much CPU or RAM your VPS needs. For H.264, YouTube’s current guidance recommends these bitrates:
| Target | Recommended H.264 bitrate |
|---|---|
| 720p30 or 720p60 | 8 Mbps |
| 1080p30 | 14 Mbps |
| 1080p60 | 17 Mbps |
Use a stable VPS outbound connection that can sustain the selected ingest bitrate, with headroom for protocol overhead and fluctuations. These figures are recommendations, not a guarantee that a provider can sustain the rate. YouTube advises checking upload bitrate with a speed test, testing with representative audio and motion, and monitoring stream health (YouTube’s live encoder settings and bitrate guidance).
Continuous streaming also uses substantial monthly transfer. Estimate usage from the actual outgoing bitrate and planned uptime, then compare it with the chosen plan’s included transfer and overage terms. Confirm how the provider counts outbound traffic; do not judge a plan by its base compute price alone.

Validate the VPS before paying for a long term
- Install your intended FFmpeg build. Confirm the build includes the encoders and features your command needs; available options vary by build (FFmpeg codec documentation).
- Run the exact playlist command with representative media. Include the actual resolution, frame rate, audio settings and YouTube ingest bitrate. If you will encode, pay particular attention to demanding scenes and verify reported speed stays at least
1x. - Observe the server while it runs. Check CPU, RAM, disk, network activity and FFmpeg logs. For a packet-copy loop, look for unexpected CPU use or unstable output; for encoding, look for speed dropping below real time.
- Test continuity and the platform path. Run long enough to observe process stability and reconnect behavior, then check YouTube stream health and the provider’s transfer accounting.
- Review the plan terms against the test. Confirm sustained-CPU policy and billing for the plan and region you intend to use before extending the commitment.
YouTube recommends testing before going live and monitoring stream health. The length and instrumentation of a VPS trial are practical precautions, not a guarantee of uninterrupted streaming.

- FFmpeg speed stays below
1xduring encoding: the workload is falling behind. Test a less demanding resolution, frame rate, codec or preset, reduce costly filters or parallel jobs, or move to compute that sustains the measured load. Re-test the exact setup. - CPU use is unexpectedly high during a supposed loop: check that the command is not re-encoding, scaling or applying filters, and check for other processes competing for CPU.
- YouTube reports poor stream health or an unstable connection: check that the VPS’s sustained outbound capacity exceeds the chosen bitrate with headroom, verify the configured ingest settings, and test again with representative content. Use YouTube’s stream-health feedback rather than treating the plan’s advertised network speed as proof of a stable route.
- Media will not fit or the server runs out of disk: account for the actual playlist files, logs and temporary files; outgoing bitrate does not determine local media storage requirements.
- Transfer costs exceed expectations: check the provider’s traffic accounting and overage terms, then estimate monthly use from actual bitrate and uptime before selecting a plan.
- The stream stops after a process or connection failure: inspect FFmpeg logs and your process supervision and restart setup, then test reconnect behavior. A VPS configuration alone does not guarantee an uninterrupted stream.
Or let it run in the cloud
If you would rather not maintain FFmpeg on a VPS, StreamNeo keeps an uploaded video or playlist looping to YouTube from the cloud: upload, add your YouTube stream key, and go live. Nothing has to stay on at home; it accepts uploads as made up to 4K 60fps at one flat price per slot, with automatic recovery if YouTube drops the stream. The first day is free with no card. Monthly pricing is $9.99 per month. Start the free day on StreamNeo.
