You can send a local video file to YouTube Live from Ubuntu with FFmpeg by enabling live streaming on your channel, copying the event’s RTMPS ingest URL and stream key from YouTube Studio, then running FFmpeg with real-time input, compatible encoding, and the correct destination. For a scheduled event, starting FFmpeg is not enough: check the preview in Live Control Room and click Go live.
Before you start
- Your YouTube channel must be verified and must not have had live-streaming restrictions in the previous 90 days. YouTube’s eligibility and setup guidance is in its live streaming help.
- Have the video file and a working internet connection on the Ubuntu computer. This method runs FFmpeg locally, so the computer and connection need to remain available for the stream’s duration.
- Install an FFmpeg build that includes the encoders, muxer, and RTMPS support you intend to use. Availability depends on the build; check
ffmpeg -versionandffmpeg -protocols, and inspect available encoders withffmpeg -encoders. - Keep the stream key private. Treat it like a password: do not put it in a shared script, screenshot, public log, or command history. Reset it in YouTube’s stream settings if you think it has been exposed.
Create the YouTube Live event and get its ingest details
- Open YouTube Studio and go to Create > Go live to open Live Control Room. Create an immediate stream or schedule one for later.
- In the stream or encoder settings, copy the stream URL and the stream key for that event. Use the RTMPS address where available. YouTube describes RTMPS as an encrypted extension of RTMP in its RTMPS setup guide.
- Use the endpoint currently displayed in your account. Do not copy a hostname from an online command example: YouTube’s ingest address and the key are tied to your setup and event.
A scheduled event can be promoted and can offer reminders. Its public start is still a separate action: after the encoder connects, inspect the Live Control Room preview and click Go live when you are ready.
Choose settings that fit the source and connection
YouTube’s current encoder settings list RTMP/RTMPS ingest, recommend RTMPS, and support H.264, H.265/HEVC, or AV1 video. Recommendations can change, so consult that page before a real event, especially if you are using a codec other than H.264.
- Frame rate and keyframes: YouTube supports up to 60 fps, recommends a two-second keyframe interval, and says not to exceed four seconds. Set the GOP length to twice the source frame rate for a two-second interval: for 30 fps, 60 frames; for 60 fps, 120 frames.
- Rate control and bitrate: use constant bitrate (CBR). For H.264, YouTube lists recommended ranges of 5–14 Mbps at 1080p30, 6–17 Mbps at 1080p60, 3–8 Mbps at 720p30, and 3–8 Mbps at 720p60. Choose a rate your upload connection can sustain; these are ingest recommendations, not a guarantee of stable delivery.
- Audio: YouTube lists AAC or MP3 for RTMP/RTMPS. For stereo, its recommendations specify 44.1 kHz and 128 Kbps; for 5.1 audio, 48 kHz and 384 Kbps, with AAC required for 5.1 over RTMP/RTMPS.
- Color: for SDR, YouTube recommends Rec. 709. Match the output to your source rather than assuming every file has the same resolution, frame rate, audio streams, or color characteristics.
These settings govern the encoded feed, not necessarily the existing file as-is. If the source’s frame rate, resolution, codec, or audio layout differs, FFmpeg may need to convert it. YouTube recommends checking upload capacity and testing with representative movement and audio.

- Compact & Travel-Friendly: The ultra-compact design allows the adapter to stay plugged into your device without blocking adjacent ports or adding bulk, reducing wear and tear on your original USB ports.
- 12-Month Warranty: Backed by a 12-month manufacturer warranty for peace of mind. Designed to meet strict quality control standards for reliable everyday performance.
Run FFmpeg to send the video
The following is an illustrative H.264/AAC command pattern, not a tested command for every Ubuntu FFmpeg build, input file, or YouTube endpoint. Replace the placeholders, adapt the frame rate and GOP, and verify that your build supports libx264 and RTMPS before relying on it.
ffmpeg -re -stream_loop -1 -i input.mp4
-c:v libx264 -preset veryfast -b:v 6000k -maxrate 6000k -bufsize 12000k
-g 60 -keyint_min 60 -sc_threshold 0
-c:a aac -b:a 128k -ar 44100
-f flv 'rtmps://CURRENT_INGEST_URL/STREAM_KEY'- Replace
input.mp4with the local file path.-rereads the file at approximately its native playback rate instead of sending it as fast as the machine can process it. - Keep
-stream_loop -1only if you want continuous repeat playback. Remove it for one pass. A loop repeats the file; it does not create new material or change YouTube’s content policies. - Adjust
-gand-keyint_minfor the source frame rate. The example’s value of 60 corresponds to a two-second interval only for 30 fps. For 60 fps, use 120. The command’s 6000 Kbps video bitrate is an example, not a universal setting; choose a value within YouTube’s current range for your resolution and frame rate that your connection can sustain. - Replace the destination with the RTMPS URL and key copied from Live Control Room. Avoid pasting a real key into a shared script or a shell command that will be saved in history. Use a protected secret-handling method appropriate to your setup.
FFmpeg options and supported encoders vary by version and build. If an option or encoder is unavailable, check the local FFmpeg help and build details rather than assuming Ubuntu packages all include the same features.

Preview, go live, monitor, and stop
- For a scheduled stream, start FFmpeg at least 15 minutes before the scheduled time, as YouTube recommends, and wait for the event preview in Live Control Room. For an immediate stream, monitor the incoming feed there as well.
- Check YouTube’s stream-health messages, confirm the expected video and audio, and verify the event is accessible from its watch page or channel page. A running FFmpeg process alone does not confirm a good or public stream.
- For a scheduled event, click Go live in Live Control Room when the preview is ready. YouTube also recommends setting up the encoder well ahead of time, testing the expected kind of motion and audio, and continuing to monitor quality.
- When finished, end the event in Live Control Room where applicable, then stop FFmpeg. YouTube says streams under 12 hours are automatically archived; do not assume that statement applies to longer sessions.
Troubleshooting
- No connection or a timeout: confirm the event’s current RTMPS URL and key, check that the destination uses the right scheme and server, and verify RTMPS support in your installed FFmpeg build.
- TLS or SSL error: make sure you copied the RTMPS address rather than an RTMP one. If the endpoint otherwise appears correct, YouTube’s guidance suggests trying port 443 where appropriate; use the current account-provided endpoint rather than constructing a server address from memory.
- No preview in Live Control Room: check that FFmpeg is sending to the URL and key for the selected event, inspect FFmpeg’s output for errors, and check YouTube’s control-room messages.
- Buffering or unstable ingest: test upload capacity, lower resolution or bitrate to a sustainable level, and test using representative motion. The chosen bitrate must fit the available upstream connection.
- Missing or unsupported audio: inspect the input’s audio streams and FFmpeg mapping, then use an audio codec and sample rate supported by the selected ingest settings. YouTube currently lists AAC or MP3 for RTMP/RTMPS.
- FFmpeg rejects an option or encoder: inspect
ffmpeg -version,ffmpeg -encoders, andffmpeg -protocols. The installed build may not include the requested encoder or protocol support. - Stream runs but viewers cannot watch it: verify preview, stream health, the event’s public status, and audio/video playback on the watch page. A process that has not exited can still be sending a feed with a wrong key, poor quality, or the wrong event state.
Copyright and YouTube channel rules
Using a prerecorded file does not grant permission to stream its music, gameplay footage, or other included material. Make sure you have the rights or permissions needed for the video and audio, and review YouTube’s applicable copyright rules before broadcasting. A continuously repeated video also remains subject to YouTube’s channel and monetization policies; looping it with FFmpeg does not guarantee eligibility or monetization.
