VidTransDub

The latest version of the plugin now supports Udemy in addition to YouTube, allowing you to watch Udemy's online courses using the plugin.

VidTransDub is a browser plugin designed for watching foreign videos online. Unlike traditional subtitle plugins, it translates subtitles and directly plays the translated content, eliminating the hassle of reading subtitles while watching videos and improving viewing efficiency.

Currently supported features:

One-click translation and video playback by clicking the play button.
Multiple browser support (Chrome-based browsers, Firefox, Safari iOS version).
Multi-site support: Currently supports youtube.com and udemy.com.
Multiple voices: Switch between different voices during playback. Selecting different target languages will trigger different voice libraries.
Playback speed support: Adjust the speed directly on the video being watched, and the plugin will adapt.
Adjustment of original and target audio volume (not supported due to iOS system limitations).
