You can use FFmpeg on a Windows PC to send prerecorded video to YouTube Live, but a reliable 24/7 channel takes more than starting an FFmpeg process. You must configure YouTube’s ingest settings, make playback repeat, keep the PC awake, and plan separately for process and network failures. The exact playlist-loop command depends on your FFmpeg build and playlist format, so verify it on your setup rather than relying on an untested copy-and-paste recipe.
What you need to set up
- A Windows PC that can read your video files and sustain the upload bitrate you choose.
- An FFmpeg build whose available demuxers, filters, and encoders you have checked against the method you plan to use.
- A YouTube channel with access to Live Control Room and a configured stream.
- A playlist method that you have tested for repeat behavior, missing files, and media compatibility.
- A plan to keep Windows awake and to restart or monitor FFmpeg if it exits.
These are separate requirements. A playlist that repeats does not automatically recover a dropped YouTube publishing session, and a reconnect option documented for one input protocol does not ensure recovery of an outgoing RTMP or RTMPS stream.
Configure the YouTube Live stream
- Open YouTube Studio and go to Live Control Room. Create or select the stream you intend to use. YouTube’s encoder workflow provides a stream URL and stream key.
- Copy the stream URL into FFmpeg’s server or output URL setting. Use the URL provided for that stream rather than assuming an ingest address.
- Provide the stream key using the method supported by your chosen FFmpeg command. Treat it like a password: do not publish it, include it in screenshots, or share it in logs. If you believe it has been exposed, reset it in Live Control Room and update the encoder configuration.
- Choose the video and audio encoding settings. YouTube recommends RTMPS, H.264, H.265 (HEVC), or AV1 video; AAC or MP3 audio; constant bitrate (CBR); up to 60 fps; and a 2-second keyframe interval that does not exceed 4 seconds. Check current YouTube encoder guidance for the ingest settings applicable to your stream.
- Run a test before relying on the channel. Use motion and audio representative of the actual content, then watch stream health in Live Control Room.
YouTube’s recommended H.264 bitrate examples include 10 Mbps for 1080p at 30 fps and 17 Mbps for 1080p at 60 fps. These are platform recommendations, not guarantees of quality or stability; select settings your PC and internet connection can sustain and verify the result in a test.
Choose and verify a playlist loop
There is no single copy-and-paste command established here for every Windows PC: the right command depends on the FFmpeg build, file formats, playlist type, and whether the source is audio-only or audio-video. Confirm your build and test the playlist behavior before scheduling a long broadcast.

High-speed wireless connection technology, reliable and efficient transmission speed, providing a faster internet experience for browsing and streaming
- Identify the inputs. Record the exact Windows paths, formats, and whether every item has compatible video and audio streams. Resolve spaces and special characters in paths using the quoting rules for the command shell you will use.
- Choose a repeat method supported by your build. Check the FFmpeg documentation and the help output of the installed build for the relevant demuxer, filter, or other playlist approach. Test with a short playlist. Do not assume that an option for repeating one file also handles a multi-file playlist.
- Check the end-of-playlist behavior. Confirm that playback reaches the end and starts again. Watch for a gap, an unexpected stop, or a timestamp/format problem at the transition. Do not describe the result as gapless unless you have tested it.
- Test imperfect inputs. Temporarily remove or rename one playlist file and try a file with different or missing audio/video streams. Note whether FFmpeg stops, skips, or continues, then decide how you will address that condition.
- Confirm the output stream independently. Verify the selected codecs, frame rate, bitrate, and keyframe interval against YouTube’s guidance, then check Live Control Room stream health.
FFmpeg’s protocol documentation includes HTTP input options such as reconnect, reconnect_at_eof, reconnect_streamed, and retry-delay limits. These describe protocol behavior; they are not a general playlist-loop switch and do not guarantee that a YouTube RTMP/RTMPS output session will reconnect successfully.
Keep the Windows PC operating continuously
A 24/7 stream depends on the host remaining awake, powered, connected, and able to read its source files. Configure Windows power settings so the PC does not sleep during operation, and arrange a way to detect and relaunch FFmpeg after an interruption. Windows Task Scheduler or a purpose-built watchdog may be part of that plan, but the exact configuration depends on the Windows version and how the command is launched; test it rather than assuming a scheduled task will restore the YouTube session correctly.

- Keep the media files in a stable location and ensure the account running FFmpeg can access them.
- Test what happens after FFmpeg exits, after the network disconnects, and after the PC restarts. These are distinct recovery cases.
- Monitor both the local FFmpeg process and YouTube Live Control Room. A process that appears to be running does not by itself prove that viewers are receiving a healthy stream.
- Before leaving the setup unattended, run a realistic-duration test and inspect the playlist transitions and recovery behavior.
Plan for YouTube’s archive limit
YouTube Help says streams under 12 hours are automatically archived. That is not a promise that a continuous 24/7 broadcast will produce one complete, intact archive. If you need archived segments, check YouTube’s current live archive guidance and decide whether your publishing plan should end and restart scheduled streams. Do not rely on a single uninterrupted broadcast as a guaranteed complete recording.
Troubleshoot common failures
| Symptom | What to check | Next step |
|---|---|---|
| YouTube does not receive the stream | The stream URL, key, selected Live Control Room stream, and encoder output configuration. | Copy the current URL and key from the selected stream, update the encoder, and check Live Control Room stream health. Reset the key if it may have been exposed. |
| FFmpeg stops at the end of the playlist | Whether the chosen repeat method applies to this playlist type and installed FFmpeg build. | Check that build’s documentation and test the loop with a short playlist. Do not treat protocol reconnection settings as playlist-loop settings. |
| Playback stops on a particular item | Whether the file exists at its listed path, is readable by the running Windows account, and has streams compatible with the output configuration. | Correct the path or replace/normalize the problematic media, then rerun the playlist test. |
| The stream drops after a network interruption | Whether FFmpeg remains running and whether the outgoing YouTube publishing session resumes. | Test reconnection and process relaunch separately. HTTP input reconnection documentation does not establish recovery for RTMP/RTMPS output. |
| The stream ends when no one is using the PC | Sleep, hibernation, power loss, and whether the process is launched again after a restart. | Review Windows power behavior and test the restart plan while monitoring Live Control Room. |
| The live stream looks unstable or unhealthy | Whether the connection can sustain the selected bitrate and whether the codec, frame rate, CBR, and keyframe settings match YouTube guidance. | Test representative motion and audio, adjust to a sustainable configuration, and monitor stream health. |
