DE: Funktioniert super, auch auf schwächerer Hardware. CPU-Auslastung steigt nur minimal. Youtube-Videos laufen flüssig. EN: Works awesome, even on weaker hardware. CPU usage rises only slightly. Youtube-Videos play smooth.
it just works! now i can watch youtube videos wearing bluetooth headphones without sound delays and with proper lipsync
cool
Works fantastic with Youtube and it's easy to setup, because the video delay can be adjusted in realtime! Perfect for fixing Bluetooth headphones with a noticeable lip sync audio delay! Thanks a lot !!
I got Bluetooth headphones recently, not realizing there are problems like audio lag. I tried another, more popular extension called Frame Sync, and while it did work, it required reloading every time you made an adjustment, and also caused anomalies with poor fps and the subtitles did not load. I tried this extension to see if it would be better - and it is! No need to reload the stream after setting the delay, no jerky video and subs are working as intended. It works perfectly. Thanks!
Needed it for watching F1 TV with wireless audio. Simple. Works like a charm, needed 250 ms for audio through a Mackie Pro DX4 mixer / wireless receiver. Just doubleclick the extension and write the desired delay. Also has a simple off switch for when using with wired audio. Thanks.
Thank you. Unfortunately not working on Netflix. I get a black screen :( Is there a workaround? Youtube working nicely on the other hand
Great extension! I set the video delay to 144 ms, which is suitable for my AirPods Max, and now the video is clear and the audio is not lagging behind. Thank you!
simple, and working
I'm using a 5600g and I have 32gb of ram, I have no dedicated gpu and I can't get it to work well on 1080p even on 60hz. Still does the job really well at lower resolutions.
