v29.2.0

Highlights

• Redesigned WebRTC webcam studio: it opens with a local camera and microphone preview that only the broadcaster sees. The channel goes live only after Start broadcast, and End broadcast returns to the preview. (c4c7bee, 9c72190, 6f8f47e)
• Stripe duplicate-charge protection: single wallet payments and subscriptions now reuse idempotency keys and use per-user locks, so retries, timeouts and double clicks do not create a second charge or customer. (1561d42, 27a6822, 8d760a1)
• AI Companion subtitles: the Companion transcript of a video can be copied to the player as a SubtitleSwitcher subtitle. This happens automatically after processing, or manually. (f1627ea)
• Category list cache: adding, editing or deleting a category is reflected immediately, instead of a stale cached list being served. Related to WWBN/AVideo#10600. (d2f0f70)

New features

• WebRTC studio (c4c7bee, 9c72190, 6f8f47e):
  • Camera and microphone selectors, including front and rear camera options. The selected devices are remembered for future visits.
  • Detects devices being connected or disconnected during a session, and shows clear messages for permission and device errors.
  • Screen sharing is under advanced settings.
  • A chat panel that does not cover the preview, a guided help tour, and pt_BR translations.
  • Status labels (Connecting, Starting broadcast, You are live, Ending broadcast) reflect what the server confirms. A lost connection keeps End broadcast available instead of assuming the broadcast ended.
• Companion subtitles in the AI plugin (f1627ea, 32ac611):
  • The transcript is saved as a SubtitleSwitcher track once processing ends. A scheduled task also covers videos whose tab was closed.
  • The automatic copy never replaces a subtitle in the same language that it did not create, such as a manual upload or an ai.ypt.me transcription.
  • The Copy subtitle to player button asks before replacing one.
  • The Companion widget icons were updated.
• Stripe single payments (plugin/StripeYPT/getIntent.json.php, YPTWallet Stripe button) (1561d42, 27a6822):
  • The PaymentIntent idempotency key is saved and replayed after timeouts.
  • A per-user guard blocks duplicate payments, timed by when Stripe recorded the charge.
  • A different amount or an expired attempt cancels the old client secret before a new one is created.
  • A repeated click only checks the existing payment's status.
  • Error responses are clearer. A definite validation error, such as an amount below Stripe's minimum, can be corrected and retried.
  • The wallet is still credited by the charge.succeeded webhook.
• Stripe subscriptions (8d760a1):
  • Subscription creation uses idempotency keys and an advisory lock across PHP workers.
  • Every Stripe customer already linked locally is checked before a new one is created.
  • Local rows whose customer was canceled, deleted or is missing are relinked to the new customer.

Fixes

• Category cache (d2f0f70):
  • The category list cache key now includes a fingerprint of the categories table, so a change shows up without waiting for cache deletion. With the Cache plugin, deletion only happens on the per-minute cron.
  • objects/categories.json.php no longer returns broken JSON when PHP prints warnings.
  • DataTables-style search[value] parameters are handled.
  • Cached directory paths are reset after cache directories are removed.
• Restreamer: plugin/Live/standAloneFiles/restreamer.json.php no longer starts a PHP session, and closes a session only if one is active. (2ad80db)

  • aws/aws-sdk-php 3.395.6 → 3.398.0 (4fcc6b4, ee791fa)

Other changes

• The Dependabot auto-merge workflow now handles errors, and its token setup is documented in .github/DEPENDABOT_AUTOMERGE.md. (62e4f8b)
• Added regression tests for the WebRTC studio, Companion subtitles, Stripe checkout and category caching. Contributor guidance now covers Stripe payments, the per-request SQL read cache and delayed cache invalidation. (c4c7bee, f1627ea, 1561d42, 27a6822, 8d760a1, d2f0f70)

Upgrade notes

• Stripe restricted keys: the single-payment duplicate guard reads the charge time from Stripe, which needs the Charges: Read permission on a restricted key. The rest of the flow only needs PaymentIntents. Without that permission, the guard logs a warning and falls back to a 5-minute observation window. (27a6822)
• Single-payment state is stored under videos/stripe-payment-locks/. It is not cache, and it is meant to survive cache cleanup. (1561d42, 27a6822)
• Companion subtitles require the SubtitleSwitcher plugin to be enabled. Otherwise the Companion tab asks you to enable it. (f1627ea)
