Patch notes (1.3.4)

Bug fixes

• Stream-end save is not dropped while the monitor loop is running — yt-dlp exit 1 (live ended, Did not get any data blocks) starts an async “still live?” check before save. hasActiveRecording treated the dead process as a stale slot and deleted it, so the close handler returned without copying the MP4. The check is now read-only; only save/retry paths clear the slot.
• Help → About no longer opens the logs folder when you close the window with X — Windows maps the title-bar close button to cancel. That was hitting Open Logs Folder (the second button). Esc and X now just dismiss the dialog.
• Log timestamps and daily log files use local time — line stamps and yt-live-recorder-YYYY-MM-DD.log follow the computer’s clock (and roll at local midnight), not UTC. Recording filename prefixes were already local.

Patch notes (1.3.3)

Bug fixes

• LIVE size and speed after per-channel Stop — Stop restarts from the live edge (--no-live-from-start). The 1s size/speed ticker only sampled --live-from-start jobs, so the LIVE row came back with no KiB/s. The ticker now samples every active recording; live-edge segments are LIVE from the first byte and use disk size/rate (HLS/ffmpeg rarely fills yt-dlp progress.speed).
• Stop leaves other people’s yt-dlp alone — never taskkill /IM / pkill -x. Stop kills the spawned PID tree, then only yt-dlp/ffmpeg/ffprobe whose command line includes this app’s YTLiveRecorderTemp scratch and that segment’s rec-… folder. PyInstaller can exit the wrapper while a child keeps writing; that leftover is now stopped so remux is not EBUSY. A yt-dlp you started yourself is not matched.
• Linux Stop leftover kill matches Windows — the bundled yt-dlp is also PyInstaller: SIGKILL of the wrapper left the child running (reparented to init). Stop/resume snapshot-kill that tree (Linux /T) and session-sweep leftovers. Distro python3 …/yt-dlp is matched too; unrelated yt-dlp is not.

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.

Patch notes (1.3.1)

Bug fixes

• Long from-start recordings are no longer truncated on save — killing yt-dlp at stream end leaves .f248.mp4.part + .f140.mp4.part. ffmpeg remux used -shortest and discardcorrupt, so a YouTube DASH timestamp gap (common on multi-hour lives) stopped the copy at the first A/V overlap. Overnight jobs saved minutes (or seconds) of an 8-hour stream. Remux now copies the full parts (-max_interleave_delta 0, no -shortest) and retries a two-pass remux if the output is much smaller than the inputs. Auto-end waits ~20s for yt-dlp to close those parts (was 5s).
• LIVE DASH hang after catch-up was invisible — the ~75s “no new bytes” failover only ran during catch-up. Once the row said LIVE, a hung googlevideo URL sat there until /live went offline, then remuxed whatever tiny prefix existed. The same stall now saves and switches to the live edge. Size is logged every 5 minutes while LIVE so this shows up in the log.
• In-progress yt-dlp merge is not treated as a finished file — title.temp.mp4 has no moov yet (killed mid-merge). Finalize skipped the real .fXXX parts and published a broken .temp.mp4. Those temp merges are ignored; leftovers are remuxed instead.

Patch notes (1.3.0)

Security

• UI process is isolated — yt-dlp/ffmpeg spawn, kill, and file save run in the main process. The window uses nodeIntegration: false, contextIsolation: true, a sandboxed preload, and a frozen window.ytlr allowlist (no free-form argv, no temp-folder access from the page). Closing the app still saves recordings if the UI process has crashed. Closing/reloading the window no longer kills other programs’ yt-dlp (unchanged: PID tree only).

Tools

• yt-dlp nightly 2026.08.20.234504 (was 2026.07.23.234303)

Features

• YouTube --live-from-start — recordings start from the beginning of the stream (YouTube DVR) using yt-dlp’s native dash/m3u8 downloader (fixed upstream 2026.03.17 / #16254, in our 2026.08.20 nightly). If from-start is unavailable, real 403s before any bytes, or “no data blocks” at start, the app retries from the live edge. Per-channel Stop always resumes from the live edge. While catching up, auto-end does not kill the job just because /live looks offline (stalls after 3 minutes still save).
• Finished files are always .mp4 — Stop, stream-end, and a clean yt-dlp merge used to leave .mkv, .mp4, or .f247.mkv depending on how the job ended. Every published file is now MP4 (--merge-output-format mp4 / --remux-video mp4, ffmpeg remux of leftovers with +faststart). Premiere, Resolve, Final Cut, and similar NLEs import MP4; MKV is a common reject. Codecs are still whatever YouTube served (often VP9/Opus or H.264/AAC); this is a remux, not a re-encode.
• Per-channel Stop no longer saves a broken .f247.mkv — from-start writes separate video/audio fragments; a hard kill left a truncated video-only .part. Stop now asks yt-dlp to exit (Windows: taskkill without /F, 8s grace) then ffmpeg remuxes leftovers (-c copy, discardcorrupt, +faststart) into a closed .mp4 with audio when the audio part exists.
• YouTube player clients — without cookies, yt-dlp’s default clients (formats=missing_pot only). With Firefox cookies: tv,web_safari,mweb,web_creator. Forcing android,ios,tv on public lives skipped SABR URLs. A PO-token warning that mentions HTTP 403 is no longer treated as a from-start crash.
• Firefox cookies checkbox — Chrome/Edge cookie options are removed. Check Use cookies from Firefox for members-only / age-restricted streams. You must be signed in to YouTube in Firefox; Firefox does not need to stay open. On Start Monitoring the app copies Firefox cookies to %APPDATA%\yt-live-recorder\cookies.from-browser.txt. A warning appears if those cookies are missing or out of date (open Firefox, sign in, Start Monitoring again).
• Download status shows stream title, size, and speed — Catch-up / LIVE rows show the stream name with downloaded size and rate (e.g. 123.6 MiB · 76.3 KiB/s). Fragment current/total is not shown (yt-dlp’s .ytdl index only moves when a DASH fragment finishes, so it looked stuck while the file was still growing). Catch-up closes and the row is LIVE once DVR catch-up finishes. After Stop, the next segment is LIVE only.
• Catch-up continues after the live ends — if /live goes offline while DVR catch-up is still running, the job keeps grabbing remaining fragments (UI: ENDED — finishing catch-up). Auto-stop only if the VOD is private/removed/members-only, or catch-up stalls for 3 minutes with no new fragments.
• Stuck catch-up fails over to LIVE — only if the fragment index and disk size are frozen ~75s (a real googlevideo hang). .ytdl current_fragment.index does not move until a DASH fragment finishes; 1080p frags can take over a minute while the .part still grows, which used to look stuck and abort a healthy catch-up.
• Catch-up downloads 8 DASH fragments at a time (--concurrent-fragments 8). Do not pass --throttled-rate (that aborts slow DVR fragments). Live-edge stays sequential.
• Live channel no longer sits idle for 10 minutes after “No video formats found” — if live-check already confirmed the stream, a miss retries in ~30s (Start Monitoring also clears that cooldown). Age-restricted lives wait 5 minutes and show a cookies hint instead of looping.
• Public lives do not need Firefox — cookies stay opt-in for members-only / age-restricted only. Without cookies the app uses yt-dlp’s default clients (visionos + webpage), which return 1080 DVR (399+140 / 248+140). Forcing android,ios,tv skipped SABR URLs and broke catch-up on every public live. Age-restricted lives still need Firefox cookies — the row shows AGE RESTRICTED: REQUIRES COOKIES in red. Checking that box retries only those blocked streams and never stops recordings that are already working.

Bug fixes

• Catch-up no longer aborts when the live ends — the ~75s DASH-hang failover (save + switch to live edge) was firing after /live went offline (log: Did not get any data blocks → “continuing catch-up of remaining DVR” → then “stuck — switching to LIVE”). There is no live edge then, so the partial file was saved and catch-up stopped. Failover now re-checks liveness; if the stream has ended, the job keeps going and, if the DVR URL is dead, resumes the same file from the VOD (watch?v=). Auto-save still happens if the VOD is gone or nothing arrives for 3 minutes.
• Catch-up matches CLI --live-from-start speed — dropped --throttled-rate 100K (that flag is not a cap; it aborts a DASH fragment after 3s below 100 KiB/s and re-extracts the live, which is a VOD HTTP workaround). Slow DVR catch-up sat under 100 KiB/s for a long stretch, so the tripwire kept interrupting. Concurrent fragments for catch-up went from 3 to 8. Live-edge recordings stay sequential. There is still no --limit-rate.
• Catch-up row switches to LIVE without a fragment total — YouTube live DVR almost never reports fragment_count, so the old “within 3 fragments of total for 5s” check never fired. A catch-up that had already reached live cadence (~15 frags / 30s, live bitrate) stayed on the Catch-up row. When the count is missing, catch-up is treated as done if fragments arrive at live-edge rate (not a burst) for ~12s.
• No 15-minute sit-out after a stream ends — auto-end used to set a 900s cooldown, so a channel that dropped and came right back (tech issue, BRB) was ignored. After save, the next 20s check (or the immediate resume probe) can start a new file if they are live again.
• Stop Monitoring / stream end no longer kill other programs’ yt-dlp — 1.2.5 stopped taskkill /IM while this app still had sibling recordings, but when the last channel in the app stopped (or on startup temp purge) it still ran taskkill /IM yt-dlp.exe / pkill -x yt-dlp, which aborted every yt-dlp on the machine. Stop now kills only that job’s PID tree; leftover lock cleanup only targets processes whose command line includes YTLiveRecorderTemp.
• Cookie file on the live probe hid live channels — sending .google.com cookies to youtube.com/@handle/live redirected to Google CookieMismatch / sign-in, which has no LIVE markers, so the probe reported not live and never ran yt-dlp (e.g. @SekturVision). Probe Cookie header is YouTube-only; sign-in pages fall back to yt-dlp.
• Chrome/Edge cookies no longer abort recordings — --cookies-from-browser on Windows often fails with “Could not copy Chrome cookie database” (browser lock / Chromium encryption). The app now detects that, records without browser cookies, and retries immediately so public lives still save. Members-only still needs Firefox, a closed browser, or cookies.txt.
• Firefox cookies recorded no formats — cookie-safe YouTube clients need yt-dlp’s JS challenge solver. The app now passes --js-runtimes node:<path> (system Node, or Electron as Node) so n-challenge solving works and members/restricted lives can get playable formats.

Reliability

• Recording logs now include extractor clients, yt-dlp pid, YouTube video id, cooldown remaining, and a warning when live-check says LIVE but yt-dlp listed no formats (so a silent sit-out is visible in Help → Open Logs Folder).

Patch notes (1.2.10)

Bug fixes

• Long-run Chromium FD / shared-memory leak while monitoring — live probes and yt-dlp status checks no longer run inside the UI renderer. Multi-MB YouTube page fetches used Chromium Mojo shared memory and left deleted /dev/shm FDs growing for hours (often ~1k+ FDs after a day of 20s polls). Probes now use Node fetch + a queued yt-dlp status print in the main process (lib/live-check.js); the renderer only receives yes/no via IPC. Recording spawn is unchanged for this release (still nodeIntegration in the UI process).

Reliability

• Probe HTML body capped at 3 MiB in main (markers appear earlier; less peak memory)
• Live-check helper processes are killed from main on Stop Monitoring and quit

Notes

• After upgrading, multi-hour monitoring should keep the UI process open file-descriptor count roughly flat (dozens), not climbing into the thousands
• Concurrent recordings still use ~100 MB RAM each (yt-dlp + ffmpeg); that is expected, not this leak

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/.mkv under your folder.

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

Patch notes (1.2.8)

Bug fixes

• Scheduled / upcoming streams no longer flash Recording then idle — pages like @channel/live for a not-yet-started stream often still contain "style":"LIVE" and "isLive":true while "isLiveNow":false / "isUpcoming":true. The HTTP probe no longer treats weak LIVE chrome as live when the stream is offline-now, and yt-dlp is_upcoming is treated as not live (so we do not start a download that immediately fails with “No video formats found”).
• Cooldown skips the live check — channels waiting out a no-formats / error cooldown no longer re-run probe + yt-dlp every 20s (was spamming “starting record anyway” in the log).

Full history: see CHANGELOG.md in the project repository.

Patch notes (1.2.7)

Features

• Faster live detection — two-phase check: cheap page probe first, then yt-dlp only when needed; fixed 20s check interval (no longer user-configurable)
• Smarter end detection while recording — probe first; full yt-dlp only when the page looks offline (less hammering YouTube mid-stream)
• Reliable app close (X) — shows a please-wait status window, stops downloads, moves files to your recordings folder, then exits
• Best quality lives — bestvideo*+bestaudio/best with format sorting suited to live HLS; bundled yt-dlp 2026.07.23 nightly for current YouTube
• Cleaner filenames — YYYY-MM-DD-HH-MM - Stream Title.mkv (strips YouTube’s trailing clock from titles; no random suffix)

UX

• Cookies hint: only needed for members-only / age-restricted streams
• Separator between settings and Start/Stop Monitoring
• Remove channel mid-recording still saves the segment, then drops that channel (no auto-resume)
• Progress line shows the file name only (not full Destination: path)

Reliability

• Hybrid save path so Stop/close does not double-copy the same segment to the NAS
• Live-check queue, monitor re-entrancy guard, log prune on day roll, clearer WARN/ERROR text for testers
• FFmpeg live HLS fix (allowed_extensions) for current stream URLs

Notes

• Prefer Stop Monitoring or wait for the close status window to finish before force-killing the process
• If a save fails, use Help → Open Logs Folder and look for WARN/ERROR lines
