RedoSan-Authenticity Files

What's new since v1.0-beta.2

🗜️ File Converter

• New browser-side File Converter tool — auto-detects image, audio, video, document, and subtitle files
• Image: PNG, JPEG, WebP, BMP, GIF conversion (Canvas-based)
• Audio: 11 formats — WAV, AIFF, AU, RAW (pure-JS PCM), MP3 (lamejs), OGG, OPUS, M4A, AAC, FLAC, AMR (MediaRecorder)
• Video→Audio: Three-tier fallback (decodeAudioData → capture at 4× speed → ffmpeg.wasm with core-st)
• Document: TXT, HTML, MD, PDF, DOCX, JSON, XML, CSV
• Subtitle: SRT, VTT, ASS, SUB, SBV, TXT, LRC, TTML
• Self-hosted ffmpeg.min.js (same-origin, no CDN dependency for library)
• Progress bar with determinate (ffmpeg) and indeterminate modes
• GPL domain protection

📱 Mobile improvements

• Fixed pull-to-refresh on mode-select page (overscroll-behavior on html/body/overlay)
• Fixed nav bar overcrowding — theme & mode-switch buttons hidden on mobile (accessible via sidebar/mode-select)
• Removed sidebar red warning text

⚡ Performance

• Video→audio: reduce decodeAudioData timeout 15s→5s, skip entirely for known video extensions
• Playback-rate acceleration: try 4×, fall back 2×, then 1×
• captureStream detection hardened
• MediaRecorder → decodeAudioData → re-encode for PCM (faster than ScriptProcessorNode)
• ffmpeg runs on main thread with yield-to-browser before heavy work (UI repaint before freeze)

🔧 Fixes

• convVideoToAudioCapture onloadedmetadata wrapped in try-catch (prevented hanging on mobile)
• ffmpeg.load() has 30-second timeout — gives clear error instead of hanging forever
• Download blob URL hidden from DOM, revoked after 5s
• escAttr escapes < and > (CodeQL alert [#62])
• CSP includes CDN and blob: for media/connect-src
• All 9 video→audio ffmpeg paths tested and produce valid headers
