CaptionGo v1.1 Release Notes

CaptionGo v1.1 makes Live Captions work on significantly more video sites and streaming platforms. The speech-to-text engine has been completely rebuilt to detect audio sources more reliably, handle encrypted streams, save bandwidth by downloading only audio data, and render subtitles more cleanly on complex web pages.

• Live Captions on more sites: completely rebuilt speech-to-text engine that automatically detects audio sources from HLS, DASH, and MP4 video streams
• Automatic video stream discovery: detects video manifests and audio URLs by monitoring page network traffic, so Live Captions works even on sites without explicit audio source configuration
• Encrypted video support: Live Captions now works on sites using AES-128 encrypted audio, including more streaming platforms with protected content
• Bandwidth-efficient audio download: extracts and downloads only the audio track from MP4 files instead of the full video, reducing data usage significantly
• TikTok and hotlink-protected sites: automatically adds the correct request headers so audio predownload no longer fails on sites like TikTok that block external requests

• Live Captions no longer shows "downloading…" or "processing…" messages once subtitles have started appearing — only errors are shown
• Improved subtitle style isolation using Shadow DOM, preventing conflicts with complex web page styles
• Audio predownload settings can be updated remotely without requiring an extension update
