Mybb Premium Plugin DF Live Theater v2.0.0 — Portable, opt-in YouTube Theater

Verification record: DFV-AUDIT-20261021
Repair wave 2 — DF Live Theater 2.0.0
21 October 2026 · Sir-Vigu · Scoped staging checks passed

New standalone implementation replacing the non-loading recovered 1.4 package. This is a versioned repair/rebuild, not a recovered original archive. No production activation was performed.


Actual isolated MyBB test capture. Sample data; not a production install or a real payment/broadcast claim.

What changed

• Independent Theater page plus opt-in embeds for bare supported YouTube links in visible posts.
  
• Strict video-host/ID validation; no server-side URL fetcher.
  
• No YouTube player request until a reader chooses Load. Privacy-enhanced embed origin.
  
• Responsive player block, Cinema layout toggle and actual clipboard feedback.
  
• Broadcast labels are explicitly manual, not claims that YouTube is currently live.
  

Requirements
MyBB 1.8.40 tested; PHP 8.1+ intended (runtime tests on 8.4.26); MySQL/MariaDB; modern browser. Custom themes, external authentication, mail and provider integrations require their own staging checks.

Installation and upgrade
Back up first. Upload inc/ and jscripts/ into the MyBB root. Back up first; deactivate 1.4 without uninstalling. Upload inc/plugins/dflive.php and jscripts/dflive/, then activate 2.0. Existing compatible URL/title values are retained; replace channel handles with explicit video URLs. Legacy templates/modules are ignored, not used as dependencies.

Settings
ACP → Settings → DF Live Theater: video URL, title, manual broadcast label and post-link conversion. A valid exact video ID or supported video URL is required; a channel @handle is not a video ID.

Usage

Code:

Set a valid video URL, then open misc.php?action=dflive. Post a bare YouTube watch URL to test conversion. Named links are left alone.

Test evidence
Actual MyBB route, bare-link conversion, no request before consent, one request after consent, strict URL cases, Cinema state, clipboard contents, mobile component bounds and lifecycle routines.
The eight-release wave passed 117 scoped assertions across PHP/MyBB, browser, HTTP and lifecycle checks. Some tests used a combined plugin context; this is not a universal compatibility certificate or an independent security audit.

Limitations / breaking changes
2.0 is a breaking rebuild: no channel live-status probes, auto announcements, automatic wake-up or legacy Theater template overrides. UI is English. Browser tests used an isolated iframe response, NOT verified YouTube playback or a real live broadcast. Loading the actual player sends a request to YouTube.

Deactivate / uninstall
Deactivate stops hooks. Uninstall removes settings in the dflive group. Old 1.x template rows are left unused for cautious manual cleanup/rollback. No threads are deleted.

Original release notes
🎬 DF Live Theater v1.4 — Luxe + Full Auto
YouTube theater embeds + your live streams, merged right into the forum — fully automatic. Premium plugin.

✨ What it does

• Paste any bare YouTube link in a post → it becomes a cinematic 16:9 theater player
  
• Theater Mode merges the channel live stream into a premium on-site page
  
• Live Sense: the 🔴 LIVE pill only appears when the channel is actually streaming (auto-detected from YouTube)
  
• Auto Watch-Party Threads: when the stream goes live, a party thread auto-posts with the stream embedded — and auto-closes with an ⚫ ENDED note when the stream ends
  
• Auto-wakes — the player shows the broadcast the moment the channel goes live
  
• Cinema fullscreen (press F) + Copy invite link (press C)
  
• Every external link opens a new tab — members never lose the forum
  

🤖 The full automation

1. Streamer goes live on YouTube
   
2. Within ~2 minutes: 🔴 pill appears site-wide + the watch-party thread posts itself
   
3. Members tap the pill → watch inside the Theater, right here
   
4. Stream ends → thread auto-closes as ⚫ ENDED
   

🎥 Proof — this bare link in this post became a theater player:
