Overview

Product summary

Review the store description, core capabilities, and common use cases.

Allows synchronisation of 2 HTML5 video and audio streams even on different tabs. Just click the popup to scan each page and press the "Sync" button to generate sync buttons next to the video/audio, then click them (preferably when both are paused at the right times) to synchronise. Press the "Flush" button to remove synchronisation.

The streams will pause, play, change playback rate and seek together.

You can check the Developer tools console for information.

N.B. You may have to go to "chrome://extensions/" and click the reload icon for this extension if the delay does not show up on the green sync button.

Changes:

15/01/2023 - More efficient code used when finding streams.
