There is no universal SRS VPS minimum for streaming a playlist to YouTube all day. SRS documents Docker deployment and an FFmpeg publishing example, including a looping input, but does not specify a guaranteed CPU, RAM, storage, or bandwidth requirement. Size the VPS for your actual media and workflow, then test the complete path before relying on it.
How the playlist-to-YouTube setup fits together
A typical relay is playlist input → FFmpeg → SRS → YouTube Live. SRS’s Docker getting-started guide shows how to run SRS and publish to it with FFmpeg; its example uses -stream_loop -1 to loop an input file. The SRS project describes its protocol and Docker support.

These are building blocks, not a complete, tested YouTube playlist configuration or a promise that a particular VPS will run unattended all day. Configure the YouTube destination and stream key separately, keep the key private, and test the entire route from playlist through SRS to YouTube Live Control Room.

What VPS resources should you choose?
The official SRS setup guide does not state a minimum CPU, memory, storage, or network plan. Any specific VPS size should therefore be treated as a workload-based estimate, not an SRS requirement. Your sizing depends chiefly on whether FFmpeg copies compatible streams or decodes and re-encodes them.
#1 Best Overall
Check these factors before choosing a plan
- Processing mode: Stream copying compatible audio and video avoids the decoding and encoding work that transcoding requires. If you must transcode, scale, or change codecs, CPU capacity matters more. This is engineering guidance, not a benchmark or published SRS minimum.
- Media and output: Note the playlist’s resolution, frame rate, video and audio codecs, and the output bitrate you intend to use.
- Network allowance: A continuous outbound stream uses sustained bandwidth. Check the VPS provider’s transfer allowance and policies against your configured output bitrate; the SRS and YouTube documentation do not establish provider-specific caps.
- Other work on the server: Account for any additional services, viewer delivery, or recording. Storage is relevant if you keep media or recordings on the VPS; it is not inherently the same requirement as relaying a playlist stored elsewhere.
- Operations: Decide how you will detect a stopped process, restart it, and restore the YouTube stream after an interruption.
Run a representative test with the actual playlist and intended settings. Observe CPU and memory, verify outbound bitrate and provider limits, and test recovery before relying on the server for a continuous broadcast.
Set the YouTube encoder output
YouTube’s live encoder settings guide lists RTMP and RTMPS and recommends RTMPS: “We recommend streaming to YouTube Live with RTMPS, a secure extension to the popular RTMP video protocol.” Its guidance includes H.264, H.265 (HEVC), and AV1 video; up to 60 fps; CBR bitrate encoding; a recommended two-second keyframe interval, not exceeding four seconds; and AAC or MP3 audio.
Choose a bitrate from YouTube’s current table for your selected resolution and frame rate rather than assuming one value works for every output. Confirm that the encoder’s output matches your YouTube stream configuration and check the incoming stream in Live Control Room.

- Test the real media and settings. YouTube advises testing before streaming, using representative audio and movement. Do this with the actual playlist and output configuration.
- Check playlist progression. Confirm that FFmpeg moves through the intended items or loops the input as expected. The documented SRS and FFmpeg examples do not establish all-day uptime for your particular setup.
- Verify YouTube’s incoming stream. Confirm that Live Control Room reports a healthy stream, then monitor stream health during operation, as YouTube advises.
- Observe resource use and transfer. Check CPU and memory under the real workload, especially if transcoding, and verify sustained network use against your VPS plan.
- Exercise recovery. Test what happens if FFmpeg or SRS stops and how you will restart the process and restore the stream. Treat this as an operational safeguard to validate, not as a guarantee supplied by SRS or YouTube.
Troubleshooting: common symptoms and checks
- YouTube does not receive a healthy stream: Check the configured destination and stream key, confirm FFmpeg is publishing to SRS, and verify the protocol and encoder output settings. Inspect the incoming stream in Live Control Room.
- The playlist stops advancing: Check that the FFmpeg input and loop behavior match the intended playlist. Review whether the FFmpeg process is still publishing to SRS.
- CPU use is unexpectedly high: Confirm whether FFmpeg is transcoding, scaling, or changing codecs rather than stream-copying compatible media. Re-test with the intended output settings and assess CPU use on that workload.
- The stream interrupts after running for a while: Check process status, provider transfer limits, and network stability. Test restart and restoration behavior instead of assuming the VPS or relay recovers automatically.
Or let it run in the cloud
If your goal is a YouTube channel that keeps playing uploaded videos without maintaining your own relay, StreamNeo is a cloud alternative: upload a recording or build a playlist, add your YouTube stream key, and go live. Nothing has to stay on at home. It streams your upload as made, up to 4K 60fps, at one price per slot; it can automatically recover if YouTube drops the stream. The first day is free with no card. Monthly billing is $9.99 per month. Start your free day with StreamNeo.
