Overview
Product summary
Review the store description, core capabilities, and common use cases.
This extension temporarily increases the playback speed of YouTube live streams with DVR enabled when a delay is detected (i.e., the red "LIVE" indicator turns gray), helping you catch up to real time.
When "Aggressive mode" is enabled in the settings, the extension continues increasing playback speed to catch up to real time as long as there is buffer, even if YouTube has not detected a delay. Aggressive mode also works on YouTube live streams where DVR is disabled.
Additional features include:
- Displaying the current playback speed
- Displaying the number of seconds delayed
- Displaying the remaining buffer size

Great extension. It really helps me stay up to date with my content!
Okay for now. Great idea. Keep updated please.
Shows latency, but doesn't actually work. Playback speed stays at 1x and never catches up.
The UI could be more stylized, but the ext works surprisingly well
Great extension, YouTube streams are faster than Twitch streams now.
もっと早くこの拡張機能に出会いたかったと思える拡張機能です。 再生速度を自動で上げてくれるので、ちょっとのラグならば会話を聞き逃すことなくすぐ最新まで追いつくことができます。YouTube Liveをよく見る方は今すぐ入れるべき。
こういう拡張機能をずっと探していたので大変ありがたいです！YouTube ライブは遅延がよく発生するのでとても助かっています。
一部の配信を見てる時に遅延していたので、この機能のおかげで更新しなおすことが減りました。
これどのくらい遅延が発生したらX倍速するのかわかりませんので、2秒遅延したら、X倍速…みたくしてほしいです！！
