YTLiveRecorder 1.3.2

Automatic YouTube livestream recorder (yt-dlp + ffmpeg).

Not affiliated with YouTube or Google.

Which file do I download?

Your computer Download this
Windows YTLiveRecorder-Windows-Setup.exe
Linux YTLiveRecorder-Linux.AppImage

Other files on this page (latest.yml, latest-linux.yml, *.blockmap, checksums) are for automatic updates — you can ignore them for a first install.

Usage

Windows

  1. Download YTLiveRecorder-Windows-Setup.exe and run it.
  2. If Windows protected your PC (SmartScreen): More info → Run anyway.
  3. Allow admin install when asked.
  4. Open YTLiveRecorder.
  5. Browse → pick a folder for finished recordings.
  6. Add channel — handle only (e.g. liquid_cryptid; @ optional).
  7. Start Monitoring. When a channel is live, recording starts.
  8. While Recording, click Stop next to that channel to save the current segment (monitoring continues; a new segment starts if the stream is still live).
  9. Stop Monitoring when done watching entirely — the app saves any active files as normal .mp4 under your folder.

Updates later: green badge next to the title, or Help → Check for Updates…

Linux (AppImage)

chmod +x YTLiveRecorder-Linux.AppImage
./YTLiveRecorder-Linux.AppImage

Same steps as Windows inside the app. AppImage supports in-app updates.

Patch notes (1.3.2)

Changes

  • Let yt-dlp run the live — one CLI-like --live-from-start --continue job on @handle/live. Catch-up vs LIVE is a UI label. A connection drop (yt-dlp dies while /live is still up) restarts yt-dlp on the same file. If the live ends during catch-up, that same file keeps grabbing remaining DVR (UI: ENDED — finishing catch-up). When the live has ended and nothing is written for 60 seconds, the file is saved and the channel goes back on the 20s live-detect loop. A new live is a new from-start job. Per-channel Stop still splits and resumes from the live edge. Cookies unchanged.
  • From-start args match a working CLI — bestvideo[height<=?1080]+bestaudio/best, no -N 8, no forced native dash, no formats=missing_pot unless Firefox cookies are on. Downloads always start at @handle/live.
  • JS runtime matches the installer — Deno is not used even if it is on PATH (npm start used to pick a local Deno). yt-dlp gets --js-runtimes node: with the Electron binary as Node, same as a packaged build. Public lives do not need it.
  • Recording scratch is on disk cache, not /tmp — Linux /tmp is often a small RAM disk (tmpfs). Overnight lives filled it (Errno 28) while the SSD still had space. Scratch is now ~/.cache/yt-live-recorder/YTLiveRecorderTemp (Windows: %LOCALAPPDATA%\yt-live-recorder\YTLiveRecorderTemp). Old /tmp/YTLiveRecorderTemp is not auto-deleted.

Bug fixes

  • Channel stop/restart is not treated as a connection drop — /live offline → wait for yt-dlp (force-save if nothing is written for 60s) → move the file → live detection. If catch-up is still unfinished and yt-dlp drops, --continue that video’s VOD (watch?v=), not /live (which may already be a new stream). Connection-drop resume (@handle/live, same file) only runs while the channel is still live.
  • LIVE label waits for both video and audio — YouTube can report 109/3071 on video while audio is already 3575/3575. Using the lagging total kept the row on Catch-up at live bitrate. Both .ytdl streams within 3 fragments of their totals (or fragment index at live-edge rate for ~12s) flips to LIVE.
  • Failed remux no longer deletes the recording — if ffmpeg cannot produce MP4 (disk full, etc.), leftover parts stay in the temp folder instead of being deleted.
  • On save, extra audio is trimmed if video died early — leftover remux of split DASH can have hours of AAC after VP9 stopped. If audio is ≥15 minutes longer than a real video duration, audio is cut to the video end. Leftover -FragN files are joined when the .part is empty.
