The example below loops a prepared video indefinitely at 720p30. Rehearse first, check YouTube’s preview and stream health, and confirm you have permission for every recording and visual you transmit.
Before you start
- YouTube Live access: Open YouTube Studio and choose Create → Go Live. YouTube says first-time live-stream activation can take up to 24 hours, so enable it well before your planned broadcast. Schedule the event if you want to promote it in advance.
- FFmpeg: Install a build that includes the
libx264encoder for the example command. Confirm availability withffmpeg -encoders. - Media you may stream: Prepare an audio-video file with a video stream. An audio-only recording needs a still image or other visual combined with it; the command below applies video filters and will not work unchanged on an audio-only input.
- Stable upload: Choose a bitrate your internet connection can sustain. Test the connection and stream with representative media before the event.
- Rights: Confirm permission for the actual composition, recording, performance, lyrics, and visual assets, including live transmission and any resulting archive. A devotional subject or language does not make a recording public domain or cleared for streaming.
Create the YouTube Live event and protect its key
- In YouTube Studio, select Create → Go Live to open Live Control Room. Create or select the event and choose the encoder workflow.
- Copy the current server URL and stream key shown for that specific event. Prefer the RTMPS address when YouTube offers it. YouTube recommends RTMPS, its secure extension to RTMP.
- Keep the key private. Treat it like a password: do not publish it, expose it in a public script, or include it in screenshots. If it is exposed, replace it in YouTube Studio before streaming.
- Keep the event open in Live Control Room. You will use its preview and stream-health feedback to check the incoming signal before making the broadcast public.
Choose settings for the programme and connection
Tamil devotional content does not require a special YouTube codec or bitrate. Use YouTube’s current encoder guidance and select settings your source and upload connection can sustain. The figures below are YouTube Help recommendations checked in 2026; the page does not state a publication year.

| Setting | Practical starting point | What to consider |
|---|---|---|
| Resolution and frame rate | 1280×720 at 30 fps | A reasonable starting profile for a prepared programme. Higher resolution can require more upload capacity. |
| Video codec and bitrate | H.264; 4 Mbps for 720p30 | YouTube currently lists 4 Mbps for H.264 720p30. Its table lists 5 Mbps minimum and 14 Mbps recommended for H.264 1080p30. These are platform recommendations, not a guarantee of quality. |
| Rate control | Constant bitrate | YouTube recommends constant bitrate. Use a target your connection can maintain consistently. |
| Keyframes | Every 2 seconds | YouTube recommends a two-second keyframe interval and says not to exceed four seconds. |
| Audio | AAC stereo, 128 kb/s, 44.1 kHz | YouTube’s advanced settings recommend 128 kb/s and 44.1 kHz for stereo audio. |
| Transport | RTMPS where offered | Use the address displayed for the event in Studio, rather than assuming a fixed ingest host. |
YouTube supports H.264, H.265, or AV1 video and AAC or MP3 audio over RTMP/RTMPS. This example uses H.264 and AAC, encoded into the FLV output FFmpeg uses for this RTMP-family workflow. Consult the current YouTube encoder settings in Studio if you change codecs or resolution.
Send a prepared programme with FFmpeg
Replace INPUT.mp4 with a file you control. In the environment variable, replace the example address with the complete current RTMPS URL and key shown for your event. Do not paste a real key into a shared script or public terminal log.
export YT_INGEST='rtmps://YOUR_CURRENT_INGEST_ADDRESS/YOUR_STREAM_KEY'
ffmpeg -re -stream_loop -1 -i INPUT.mp4
-vf "scale=1280:720:force_original_aspect_ratio=decrease,pad=1280:720:(ow-iw)/2:(oh-ih)/2,setsar=1"
-r 30 -c:v libx264 -preset veryfast -pix_fmt yuv420p
-b:v 4M -maxrate 4M -bufsize 8M -g 60 -keyint_min 60 -sc_threshold 0
-c:a aac -b:a 128k -ar 44100 -ac 2
-f flv "$YT_INGEST"The example fits the source into a 16:9, 1280×720 frame without stretching it, sends at 30 fps, targets a 4 Mbps video bitrate, and sets a 60-frame GOP (two seconds at 30 fps). It assumes your FFmpeg build has libx264 and the input contains both audio and video. If your source is already compliant, you may not need the scaling and padding filters.
Looping, finite playback, and audio-only files
-repaces a prepared file at its native rate so FFmpeg sends it in real time rather than as fast as it can read it.-stream_loop -1repeats the input indefinitely. It must appear before the input it applies to, as in the example. Remove it for a finite programme; FFmpeg will stop sending when the file ends.- For audio-only devotional material, first combine the audio with a still image or other suitable visual, or build a separate command for the inputs you intend to use. Do not apply the video filter to an input with no video stream.
- If you need to loop audio and video independently, arrange the inputs or filters accordingly and verify synchronization during rehearsal.
Start and verify the broadcast
- Run the command and watch FFmpeg’s output for connection or encoding errors.
- Wait for the incoming signal to appear in the event’s YouTube preview. Check that the image is correctly framed and the devotional audio is audible and synchronized.
- Review YouTube’s stream-health messages. In a scheduled-event workflow, click Go Live in Live Control Room when the preview and health checks are satisfactory.
- Monitor the stream while it is live. YouTube says streams under 12 hours are automatically archived; confirm the archive and its rights suitability for your channel.
Rehearse and troubleshoot common problems
| Symptom | Likely cause | What to check or change |
|---|---|---|
| No preview in Live Control Room | Wrong event URL or key, key copied incorrectly, or encoder has not connected | Use the current URL and key from that event. Check FFmpeg’s output and confirm the key is private and correctly supplied. |
| FFmpeg reports an unknown encoder | The installed build does not include libx264 |
Check ffmpeg -encoders and install or select a build with that encoder, or use a video encoder supported by your build and YouTube. |
| Video-filter or stream errors | The input is audio-only or its streams differ from the command’s assumptions | Inspect the file’s streams, add a visual for audio-only content, and adapt the filter and mapping to the actual inputs. |
| Repeated disconnects or poor stream health | Upload bandwidth is unstable or cannot sustain the selected bitrate | Test the connection and lower the resolution or bitrate to a profile it can hold reliably. Rehearse again before going public. |
| Image is stretched, cropped, or letterboxed unexpectedly | Source aspect ratio differs from the 16:9 output canvas | Check the scale-and-pad filter and preview. The example preserves the source ratio and pads the remaining canvas rather than stretching the image. |
| Programme stops when the file ends | The input is not configured to loop | Use -stream_loop -1 before the relevant input for an indefinite repeat, or retain finite playback if the event should end. |
| Audio is absent, distorted, or out of sync | Missing audio stream, incompatible input, encoding issue, or independently looped inputs | Check the source audio, test AAC output in rehearsal, and verify synchronization if using separate audio and video loops. |
