Scan for outdated or missing drivers - takes under a minuteDriver Scan →Clear out junk files and repair common Windows errorsFree Scan →Run two prerecorded YouTube Live loops from one VPS by launching two independent FFmpeg processes. Give each process its own media input, YouTube stream key, log, and restart policy; pace file playback in real time with -re; and use -stream_loop -1 to repeat the input indefinitely. Before relying on it, test both streams together: the VPS must sustain their combined upload bitrate, and any re-encoding must fit its available CPU.
What you need before starting
- A Linux VPS with both media files available locally and enough disk space for them.
- Two YouTube Live stream configurations, each with its own stream key and ingest URL from YouTube Studio’s Live Control Room.
- An installed FFmpeg build with the protocols and codecs required by your inputs and outputs.
- A plan to monitor both FFmpeg processes, outbound network use, and YouTube’s stream health.
Use the exact RTMPS endpoint displayed for each stream. YouTube recommends RTMPS, which encrypts the connection using TLS/SSL; do not assume an RTMP URL and an RTMPS URL can be interchanged. A stream key tells YouTube where to accept the encoder feed, so protect it like a password. YouTube’s current help pages, accessed 2026-10-03, cover managing live stream settings and encrypting a stream using RTMPS.
Prepare each stream’s command
For a compatible local video file, this is a representative command structure for the first stream. It is an example, not a universal preset or a tested VPS sizing recipe:
ffmpeg -re -stream_loop -1 -i /path/to/stream-one.mp4
-c:v libx264 -preset veryfast -b:v 5M -maxrate 5M -bufsize 10M
-g 60 -keyint_min 60 -sc_threshold 0
-c:a aac -b:a 128k -ar 44100
-f flv 'rtmps://INGEST_URL/STREAM_KEY'- Replace
/path/to/stream-one.mp4with the actual file path. - Replace the output URL with the exact RTMPS ingest URL and stream key shown in Live Control Room. Keep credentials out of shared scripts and unredacted logs.
- Build a separate command for stream two, with its own input file, output URL, and stream key. Keep the two commands independently manageable.
- Check the media’s actual resolution, frame rate, video and audio codecs, and whether it contains audio. Set output options to match your intended stream and YouTube’s supported settings.
-stream_loop -1 repeats the input indefinitely. -re reads the file at its native rate, which is important when sending a file as a live-style feed rather than consuming it as fast as the server can read it. FFmpeg documents these options and its real-time RTMP example in the FFmpeg documentation. FFmpeg options generally apply to the next input or output, so put input options before -i and output options before the output URL.

The example’s 5 Mbps video rate corresponds to YouTube’s recommended H.264 bitrate for 720p30, but it does not mean your file is 720p30 or that these settings suit it. Confirm resolution and frame rate before using the value. YouTube’s current encoder guidance, accessed 2026-10-03, lists H.264, H.265/HEVC, and AV1 for RTMP/RTMPS video, recommends constant bitrate (CBR), supports frame rates up to 60 fps, and recommends a two-second keyframe interval that should not exceed four seconds. Consult the full YouTube encoder settings and bitrate guidance for settings specific to codec, resolution, and frame rate.
Choose stream copy or re-encoding
The sample re-encodes video with libx264 and audio with AAC, giving you control of output settings at the cost of encoding work. Each FFmpeg process that re-encodes adds work to the VPS; two simultaneous software encodes can be demanding, but there is no universal CPU-core or memory requirement established for a particular quality.

If a file already has codecs and media characteristics that YouTube accepts, stream copy may reduce CPU use. It does not change the source streams to meet a different bitrate, resolution, frame rate, or codec requirement, so check compatibility rather than assuming that copy will work. FFmpeg’s documentation describes its input and output options; test the exact media and command before leaving either stream unattended.
Run and supervise two independent processes
Start one process per stream, with distinct commands, keys, and logs. This separation is practical deployment guidance: it lets you identify which stream failed and restart it without confusing its output with the other stream. The official documentation does not provide a ready-made two-process VPS recipe.

- Run the first command and verify that YouTube receives its video and audio and reports a healthy stream.
- Run the second command and verify it independently.
- Leave both running together long enough to check sustained CPU, memory, and outbound network use, plus dropped frames and YouTube stream-health messages.
- Use a process supervisor configured to restart a process if it exits, and retain separate logs and alerts for each stream.
- Test what happens when a process or network connection fails. Do not treat a successful initial connection as proof of unattended recovery.
FFmpeg documents protocol reconnect options, including retries and reconnects for certain network errors, but those options do not guarantee recovery from every RTMP/RTMPS ingest or YouTube-side failure. Check the FFmpeg protocol documentation for the specific protocol options supported by your build, then test your configuration. YouTube also recommends testing with representative moving video and audio and monitoring stream health and messages during streaming; see its encoder guidance.
Size the network for both streams
Add the configured outgoing bitrates of both streams to estimate sustained upload demand, then leave headroom. YouTube says the total bitrate must not exceed available upload bandwidth and recommends 20% upload headroom. Applying that reserve to two independent streams’ combined bitrate is a planning inference, not a published two-stream rule. Transport overhead and bitrate variation also mean the sum of video and audio settings is not an exact measurement of real network use. YouTube’s encoder settings and streaming tips explain its bandwidth guidance.

| H.264 example | YouTube minimum video bitrate | YouTube recommended video bitrate |
|---|---|---|
| 720p30 | 3 Mbps | 8 Mbps |
| 1080p30 | 5 Mbps | 14 Mbps |
| 1080p60 | 6 Mbps | 17 Mbps |
These are YouTube’s current H.264 recommendations, accessed 2026-10-03; other codecs and frame rates have different guidance. YouTube recommends 128 Kbps for stereo audio. Verify the VPS’s sustained outbound capacity in its region and test both streams simultaneously. Leave room for other server traffic, filters, scaling, and bursts. No universal VPS CPU, memory, or network plan can be specified without knowing the provider, region, encoding mode, and media properties.

Keep YouTube’s archive and DVR behaviors distinct when choosing stream duration. YouTube says streams under 12 hours are automatically archived. Separately, DVR rewind may be limited or unavailable for streams longer than 12 hours; DVR allows viewers to pause, rewind, and resume during a live stream. Check the current channel settings and YouTube help for the behavior that applies to your stream. See creating a YouTube live stream with an encoder and turning on DVR for live streams.
Troubleshoot common failures
| Symptom | Likely cause | What to check or do |
|---|---|---|
| YouTube never receives the stream | Wrong ingest URL or stream key, or an unsupported endpoint | Copy the exact RTMPS URL and key from the matching Live Control Room stream. Check the FFmpeg error output without sharing the key. |
| One stream works, but the other does not | The second process may have the wrong input, key, URL, or conflicting configuration | Inspect its command and log separately; verify that it uses the second stream’s own destination and key. |
| Video or audio settings are rejected or unhealthy | Output codec, bitrate, resolution, frame rate, or keyframe interval may not suit the stream | Inspect the file’s properties and compare the output with YouTube’s current encoder guidance for that codec and resolution. |
| Dropped frames or unstable delivery when both run | The VPS may lack sustained upload capacity or encoding headroom | Check combined outbound bitrate and server CPU during a simultaneous test. Reduce output demands or use a VPS with adequate measured capacity. |
| A loop plays too quickly or stops at the end | Real-time pacing or infinite looping is missing or placed incorrectly | Confirm -re and -stream_loop -1 apply to the intended file input, before its -i. |
| Stream remains down after a disconnection | Reconnect behavior may not cover the failure, or FFmpeg may have exited | Inspect the process log, verify supported reconnect options, and configure and test a supervisor restart policy and alert. |
Or let it run in the cloud
