When FFmpeg disconnects from a YouTube Live stream on an OVHcloud VPS, first establish what stopped: the FFmpeg process, its network output, YouTube ingest, or something around the VPS. A VPS name alone does not identify the cause, so keep timestamps and logs before changing settings.
This guide follows those layers in order. You will compare the evidence from FFmpeg with YouTube’s stream-health feedback, then inspect the host and route, changing one thing at a time. Do not share your stream key while collecting or asking for help.
Capture the disconnect evidence safely
Start a record before the next test, rather than relying on memory after an overnight interruption. Note the date and time, including the time zone, when the stream started, when the picture disappeared, when FFmpeg reported an error or exited, and when YouTube’s Live Control Room changed its status. If the times differ, preserve each one; the sequence can help distinguish a local process event from an ingest warning.
Save the complete FFmpeg startup banner, which identifies the installed version and build configuration, along with the exact command used to publish. Keep the command private and replace the stream key and any other credentials with a clear marker such as [REDACTED] before sharing it. Check arguments, environment variables, shell history and copied logs for a key as well: redacting only the most obvious part of the command is not enough.
Preserve the surrounding log lines, not only the last error. A message shortly before the disconnect may explain what FFmpeg was doing, while the final line may merely report that a connection closed. Record whether the process disappeared, stayed running, began writing output again, or required a manual restart. Take a note or screenshot of the corresponding YouTube stream-health message and the event or ingest endpoint selected in the Control Room.
A compact incident note can include the VPS plan and region, the stream resolution and frame rate, output protocol, process start and failure times, relevant resource readings, firewall changes, and the exact health message. Add facts you measured, not guesses such as “the host dropped it”. This is useful whether you later review the issue yourself or ask support to investigate.
The distinction between a machine used as a stream host and a local computer matters when planning the next test. The VPS versus spare-PC comparison can help you think through which operating environment you can observe and maintain; it does not establish the cause of a particular disconnect.
Did FFmpeg exit or keep running?
First check whether the FFmpeg process still exists after the picture stops. Use the process manager or service supervisor you already use, and compare the result with the process ID and log timestamps. If the process exited, find out whether it ended normally, reported an error, or was stopped by a supervisor, operating-system event, or manual action.
If FFmpeg is still running, that does not mean it is still sending a usable stream. Look for continuing output, a connection or write error, a stalled input, or a process that is alive but making no progress. If the log is quiet, compare file positions, resource use, and the latest output timestamp where available. A static process listing cannot tell you whether media is reaching YouTube.
Classify the incident provisionally:
| Observation | What it narrows down | Next check |
|---|---|---|
| FFmpeg exited | Process failure or external stop is possible | Capture the exit status, final log lines and supervisor or system events |
| FFmpeg remains alive but reports a write or connection error | The publishing output needs investigation | Read the error in context and compare YouTube health at the same time |
| FFmpeg appears active while YouTube reports unhealthy or no incoming video | The process and ingest do not agree | Check stream key, destination, output settings and health details |
| The stream resumes without a process restart | A transient or recovered condition is possible | Record how long recovery took and whether media continuity was affected |
These are directions for diagnosis, not conclusions. For example, an FFmpeg connection error does not by itself prove whether the endpoint, route, firewall or host caused it. Likewise, a YouTube warning does not show whether the warning preceded the output failure or followed it. Use the timestamps to establish the order.
If you operate a looped file rather than a changing live camera feed, note whether the input itself reached its end or stopped being readable. The FFmpeg looping guide for YouTube Live offers context for that sort of publishing setup, but options and examples must still match your installed FFmpeg build and command.
Read FFmpeg output and logs around the incident
Read the log from startup through the failure, then zoom in on the minutes around the recorded time. Identify whether FFmpeg opened the input successfully, began the expected output, and continued to report progress. Search for connection closures, write failures, timeouts, input read errors, timestamp warnings, and exit messages, but interpret each against the lines around it. The same word can mean different things depending on whether it refers to the input or the YouTube output.
Check that the destination and stream key correspond to the active YouTube event. Do not paste the full publishing URL into a public forum if the key is embedded in it. Redact that part while retaining enough context to show whether the endpoint is RTMP or RTMPS and which command options are being used. If you need someone to review a command, provide the FFmpeg version, build banner and sanitized arguments together.
FFmpeg’s protocol documentation describes RTMP as multimedia streaming over TCP/IP and documents protocol options including tcp_keepalive and rw_timeout. Keepalive enables a basic operating-system mechanism that can help detect a dead peer or maintain a long-lived idle connection; platform-specific tuning remains outside that option. The generic read/write timeout is expressed in microseconds. These settings affect connection behaviour and observability, but neither is proof that a route is healthy or a universal repair for a failed output.
Be careful with advice copied from HTTP input examples. FFmpeg documents options such as reconnect and reconnect_at_eof in the HTTP protocol context. Do not assume those flags automatically reconnect an RTMP publishing output just because they appear in a command found online. Confirm that an option applies to the protocol and direction you are using, and check the documentation for your installed version.
The FIFO muxer is a separate output strategy that can buffer packets and attempt recovery from temporary failures. A development-list example shows a pattern using -f fifo, -fifo_format flv and recovery-related options with an RTMP destination. Treat it as something to validate in a controlled test, not a promise of seamless continuation. Buffering, dropped packets, delay, timestamp continuity and YouTube’s response all need checking on your actual build and stream.
Check YouTube ingest health and encoder settings
Open the YouTube Live Control Room for the event that was active when the interruption occurred. Record the stream-health status and any message shown, then check whether the selected event, stream key and ingest destination match the FFmpeg command. A key can be valid yet belong to another setup or event, so compare the actual configuration rather than assuming that an old saved command is still right.
YouTube’s encoder settings guidance recommends RTMPS, constant bitrate (CBR), and a two-second keyframe interval that should not exceed four seconds. Recommended codec and bitrate depend on resolution and frame rate. For example, YouTube’s guidance lists H.264 1080p30 at a 5 Mbps minimum and 14 Mbps recommended, and H.264 1080p60 at a 6 Mbps minimum and 17 Mbps recommended. These are YouTube encoder recommendations, not measurements of the upload capacity available to your VPS.
Compare your command and output with the current YouTube guidance for the exact format you are sending. Check that the codec, resolution, frame rate, bitrate mode and keyframe interval are intentional, rather than inherited from an unrelated sample. YouTube advises testing before an event and monitoring stream health. A short test can reveal a configuration mismatch; a longer observation may be needed to examine a recurring overnight interruption.
Then compare chosen bitrate with sustained outbound capacity from the VPS, allowing for protocol overhead and other traffic. Do not infer capacity from the plan name or a single brief speed test. Measure during the hours when the problem occurs if practical, and note whether other jobs share the same outbound connection. A short-lived capacity dip can matter even if the average looks adequate.
If you change from RTMP to RTMPS or adjust encoder settings, use the same event conditions where practical and record the new health messages. YouTube recommends RTMPS, but selecting it does not diagnose a prior failure or guarantee that the stream will remain connected. Keep the active stream key private in every test report.
Inspect the VPS process and operating environment
Next examine the host at the exact incident times. Check CPU and memory pressure, available disk space, input-file access, process restarts, and the service manager or scheduled tasks that launch FFmpeg. If the process was restarted, find the corresponding reason and timestamp. A restart may restore video, but it also hides whether the original failure came from FFmpeg, the host or the network unless you preserve the earlier evidence.
Review firewall rules that apply to outbound traffic and any recent changes to them. Confirm that the process can reach the configured destination and that a local policy, security tool or custom rule is not closing or blocking the connection. Avoid broad firewall changes as a first test. If a specific rule seems implicated, document the current rule and test a narrowly scoped change that you can reverse.
Check for local input stalls too. A file on a full or unavailable disk, a mounted volume that pauses, or an input process that stops delivering frames can leave the publishing output in a state that looks like a network problem. Compare FFmpeg’s progress and input messages with the moment YouTube reports trouble. The observation should tell you whether the media stopped before the connection did, or the other way round.
A 24/7 stream is also an operating routine: someone needs a way to see a stopped process and distinguish it from a stream that is still sending. If you are comparing a VPS with an always-on computer you control, the second-hand desktop PC guide discusses practical considerations around running a stream continuously. The right choice depends on what you can monitor and maintain, not on an assumption that one type of host cannot disconnect.
Do not attribute the issue to OVHcloud without evidence tied to your actual VPS, region and incident. Check the plan and location, measured host load, relevant firewall rules, route observations and provider status for the relevant time. If you contact support, give them timestamps, affected destination, sanitized logs and the results of your checks. Those details invite a focused investigation; a provider name in an error report does not establish fault.
Consider the network path to the ingest endpoint
Once the process and host checks are in hand, consider the path between the VPS and YouTube’s ingest endpoint. RTMP uses TCP/IP, so a publishing failure can involve the endpoint, a local firewall, an intermediate route or a remote service response. A route test or connection probe can add context, but a successful probe at one moment does not prove the path remained stable during the drop.
Record which endpoint the active event uses and the protocol in the sanitized command. Compare failures across repeated tests, and note whether they occur at similar times or under similar outbound load. If the path changes or the issue stops after a configuration change, that is a clue, not definitive proof of what caused it. Keep the other variables stable long enough to make the comparison useful.
A network test should be interpreted narrowly. A route trace may show the route visible to the test at that time, but intermediate devices may not answer probes and the result does not necessarily show the path of every streaming packet. Similarly, a brief successful connection confirms reachability then, not overnight consistency. Pair these checks with FFmpeg’s error time and YouTube’s health timeline.
If you suspect an endpoint-specific issue, compare only supported endpoint and protocol choices available to your YouTube event. Do not silently switch to an unrelated server address or copy an endpoint from another channel. Keep the key private, and avoid changing firewall policy, protocol and bitrate all at once; otherwise, a better result will not tell you which change mattered.
Test one change and compare results
Make the next test small enough to interpret. Save the original command and configuration first, then change one variable: for example, correct a keyframe interval, adjust an output timeout after confirming its meaning, or test the recommended RTMPS protocol. Note the time, FFmpeg build, exact sanitized command and YouTube health result. Keep the same source file and event conditions where possible.
Compare more than whether the stream appeared to recover. Record connection stability over the same observation period, time to recover if it dropped, media lost or dropped, timestamp continuity, audio/video continuity, CPU and network use, and YouTube’s health messages. A test that reconnects but loses a section or resumes with a timestamp discontinuity may not be an acceptable result for your channel.
If evaluating FIFO output recovery, test it in a controlled window and check that your installed build supports the chosen options. Observe how buffering affects delay, whether packets are dropped, and whether YouTube accepts the stream after a transient interruption. The development-list pattern is not a general guarantee; compare the actual outcome with a simpler baseline command.
Keep an incident log with one row per interruption or test. Include the start and end times, process outcome, key FFmpeg lines, YouTube health message, host readings, route or protocol detail, and the single change under test. After several comparable observations, you may see a pattern worth investigating. Do not turn a single successful night into proof of a fix or a single failed run into proof of provider fault.
For an always-on channel, monitoring should tell you what failed, not only that the screen went dark. YouTube recommends watching stream health; pair that view with a process check and a way to preserve logs. If you are deciding how to operate a prerecorded channel while reducing the need to keep your own computer on, this guide to prerecorded YouTube streams explains a different operating approach. Choose it only if its workflow suits your content and control needs.

FAQ
FFmpeg says it is running, but YouTube shows no picture. What should I check?
A running process does not prove that usable video is reaching ingest. Compare FFmpeg’s output and write messages with YouTube’s health timeline, then confirm the active event, destination and stream key without exposing the key. Check whether the input is still producing media as well as whether the output connection is active.
Should I add HTTP reconnect flags to my RTMP publishing command?
Do not assume so. FFmpeg documents its HTTP reconnect options in the HTTP protocol context, which is not the same as recovering an RTMP publishing output. Verify an option’s applicability against the documentation for your installed build before testing it.
Does using a VPS from OVHcloud mean the provider caused the drop?
No. The available evidence must identify the cause on the particular host and route; a disconnect on a VPS does not by itself establish a provider fault. Compare process logs, host metrics, firewall rules, route observations and provider status at the incident time before drawing a conclusion.
Will RTMPS or FIFO recovery prevent another disconnect?
Neither should be treated as a guarantee. YouTube recommends RTMPS, while FFmpeg’s FIFO muxer provides a recovery strategy to test; actual results depend on the stream, build and failure. Compare continuity, recovery time, dropped media and YouTube health during a controlled test.
