FFmpeg cannot read an ordinary CSV as a playlist. First parse the CSV and turn its validated file paths into an FFmpeg concat list; then send that sequence to the stream URL and key for a YouTube Live event. This guide shows the workflow, the compatibility checks that determine whether stream copying is safe, and how to preview and monitor the broadcast.
What you need before starting
- An eligible YouTube channel and a scheduled or created event in YouTube Studio’s Live Control Room.
- FFmpeg installed on the computer that will run the broadcast. The exact commands can vary by operating system and FFmpeg build.
- A CSV playlist and the sermon video files it refers to, stored in a stable location for the event.
- Permission to publicly stream every sermon, including any music, readings, or other material covered by third-party rights.
- A reliable upload connection with capacity beyond the stream’s total bitrate, plus someone available to watch the preview and respond if the process stalls or exits.
YouTube’s current eligibility guidance says a channel must be verified and must not have had a live-streaming restriction in the preceding 90 days. It also states that the minimum age to live stream is 16. Confirm eligibility on the channel before scheduling a service: YouTube’s live-streaming eligibility guidance.

Inspect the CSV and sermon files
Check the playlist’s actual format
CSV does not define one fixed set of column names or rules. Inspect your file to identify its header, delimiter, quoting conventions, path column, and whether paths are relative to the CSV’s folder or absolute. The examples below assume the path column contains one video path per row; adapt them to your file rather than assuming a church-specific schema.
Check that every listed file exists, is readable, and appears in the intended order. Keep the CSV and media in a stable location while the event runs. If filenames contain commas, quotes, apostrophes, or other unusual characters, use a real CSV parser and correctly escape paths for FFmpeg’s concat-list syntax; do not build a shell command by interpolating raw CSV cells.

Confirm streaming rights
Having a recording does not necessarily mean the church has permission to broadcast every element in it. Check that the church has rights for public live streaming of the sermon and any embedded music, slides, video clips, or readings. YouTube may interrupt or restrict a stream when content-rights rules are triggered.
Convert the CSV into an FFmpeg concat list
FFmpeg’s concat demuxer reads a text file in its own format, not a comma-separated spreadsheet. After parsing and validating the CSV, generate a separate text file such as sermons.ffconcat. For two compatible videos, it can look like this:
ffconcat version 1.0
file 'media/sermon-01.mp4'
file 'media/sermon-02.mp4'The header must be exactly ffconcat version 1.0 on the first line for automatic format recognition. Each file entry names one video; entries play in order. Relative paths are interpreted from the process’s working directory, so run FFmpeg from a predictable directory or generate paths with that in mind.

Keep FFmpeg’s safe-path handling enabled when practical. Its concat demuxer rejects certain unsafe paths by default. Setting -safe 0 allows any filename and can expose files beyond the intended media folder if untrusted CSV content reaches the list. Use it only when a trusted workflow genuinely requires paths rejected by safe mode, and validate and constrain every input first. See FFmpeg’s concat demuxer documentation.
Check whether the videos can be concatenated without re-encoding
Stream copying avoids decoding and encoding the video again, but it is not a universal fix for a mixed folder of recordings. FFmpeg’s concat demuxer expects the files to have compatible streams, codecs, and time bases. Compare representative files before choosing the output method; inspect stream details with a media probe such as ffprobe, which is distributed with many FFmpeg builds.
Use the concat demuxer for compatible sources
If the inputs have matching stream layouts and compatible codecs and time bases, the concat demuxer can feed them consecutively without re-encoding. Later timestamps are adjusted using earlier file durations. If a duration is missing or inaccurate, transitions may have gaps, timing problems, or audio/video artifacts. Test the complete playlist or a representative sequence before the service.

Use a re-encoding workflow for incompatible sources
If files differ in resolution, frame rate, codecs, stream layout, or other relevant properties, normalize them to a common format or use FFmpeg’s concat filter and re-encode to consistent output parameters. The filter is the appropriate concat approach when re-encoding is required; it involves more processing and should be tested on the actual recordings. FFmpeg distinguishes these approaches in its concatenation FAQ. Neither method guarantees seamless joins across arbitrary files without checking the results.

Scan for outdated or missing drivers - takes under a minuteDriver Scan →Repair Windows errors before they cause bigger problemsFix Now →Create a YouTube Live event and protect its key
- In YouTube Studio, open Live Control Room and create or schedule the live event.
- Open the event’s stream settings and copy the stream URL and stream key shown there. Use that event’s actual values; do not assume a sample endpoint applies to every account or event.
- Use RTMPS where available. RTMPS is RTMP protected by TLS/SSL, and YouTube recommends it for encoder streams.
- Keep the stream key secret. YouTube describes stream keys as like the stream’s password and address. Do not put a real key in a public script, repository, screenshot, or article.
See YouTube’s encoder setup instructions for the event workflow and current account guidance, and its RTMPS guidance for the protected protocol.
Choose encoder settings for the source and event
For RTMP or RTMPS, YouTube’s current encoder guidance lists H.264, HEVC, and AV1 as supported video codecs, with format-specific conditions; it lists AAC or MP3 audio and supports up to 60 frames per second. For a straightforward SDR sermon feed, H.264 video with AAC audio is a practical example, not a requirement that overrides the event’s format or the current YouTube guidance.

YouTube recommends constant bitrate (CBR) and a 2-second keyframe interval, and says not to exceed 4 seconds. Its guidance gives bitrate recommendations by resolution, so choose a value for the actual output resolution and frame rate rather than treating one bitrate as universal. Match the resolution to the source and the desired viewing quality; avoid upscaling a low-resolution recording merely to select a higher bitrate. Review YouTube’s current live encoder settings and bitrate table before the event, since recommendations can change.
Send the playlist to YouTube with FFmpeg
The command shape below uses stream copying and is only appropriate if the playlist’s media streams are compatible and already meet the selected YouTube output requirements. The environment variables keep the secret out of the command text, but they are not a complete secret-management system: avoid shared accounts and inspect your shell’s history and process visibility. The exact output URL syntax depends on the URL YouTube provides and the installed FFmpeg build.
export YT_URL='paste-the-event-URL-shown-by-YouTube-here'
export YT_KEY='paste-the-event-stream-key-here'
ffmpeg -re -f concat -safe 1 -i sermons.ffconcat
-c copy -f flv "${YT_URL}/${YT_KEY}"This is a shell example for environments such as Linux and macOS; shell syntax differs on Windows. It assumes the event endpoint is suitable for the shown URL form and that the concat list’s relative paths resolve from the current directory. Do not publish the event URL or key. If YouTube supplies an endpoint/key arrangement that does not fit that form, follow the endpoint format shown for the event and the output options supported by your FFmpeg build.

-re reads the files at their native rate rather than sending the entire recording sequence as fast as possible. -f concat selects the concat demuxer, -safe 1 keeps safe-path checks enabled, and -c copy avoids re-encoding. The example does not force a resolution, bitrate, frame rate, or keyframe interval; copied streams retain their existing encoding. If they do not meet the event’s requirements or are incompatible with one another, use a tested re-encoding workflow with explicit video and audio settings instead of assuming this command will work.
Preview, start, and monitor the broadcast
- Start FFmpeg and wait for the event’s Live Control Room preview to show the incoming feed.
- Check video, audio, the first transition, and the sequence order in the preview before making the stream public or starting the event.
- Confirm the live page is accessible as intended, then monitor Live Control Room’s stream health during the broadcast.
- Keep an operator available to investigate a stalled feed, stop or restart FFmpeg, and confirm which sermon should play next if the process exits.
Leave upload headroom beyond the stream’s total bitrate so other network use and connection variation do not consume the whole available capacity. YouTube says streams under 12 hours are automatically archived; confirm current account and event settings, and do not assume an archive will be available for a longer stream.
Plan for a finite playlist, not an automatic 24/7 schedule
The concat demuxer plays the listed files in sequence and then reaches the end of the list. It does not automatically repeat the CSV, watch for new rows, restart itself after a failure, or schedule a new day’s playlist. Continuous unattended operation requires a separately designed wrapper or scheduler that handles looping or playlist updates, process failures, logging, and supervision. The right implementation depends on the church’s operating system and schedule; those details are not specified here.

- FFmpeg says a file cannot be opened: Check the spelling, permissions, working directory, and whether each relative path is based where you expect. If safe mode rejects a path, prefer generating safe relative paths; only consider
-safe 0for validated, trusted inputs. - The list is treated as malformed: Confirm it is a text concat list rather than the original CSV, that the header is exact and on line one, and that every entry uses
file 'path'syntax. Escape unusual path characters correctly. - FFmpeg reports mismatched streams or the joins glitch: Probe the files for differences in streams, codecs, time bases, and durations. Use compatible files with the demuxer, or normalize/re-encode with a concat-filter workflow; test transitions before going live.
- YouTube does not receive a signal: Recheck that the event is live or ready to receive an encoder, that the stream URL and key belong to that event, and that the URL form matches YouTube’s endpoint. Keep the key private while correcting it.
- The feed is rejected or has poor quality: Compare the actual codec, bitrate, resolution, frame rate, audio format, and keyframe interval with YouTube’s current recommendations for that format. A stream-copy command cannot change those properties.
- The stream drops or stops early: Check the upload connection and FFmpeg’s output, then have an operator restart or investigate the process. A finite list ending normally is different from a crashed process; neither behavior creates a repeating schedule by itself.
