Is there any way to get the frequency data of the stream?
I want to read the frequency data to make an audio response visualizer.
Can I link somehow the audio src to the stream video element with Web Audio API?
An extension does not have access to the stream running on the same page.
To get audio information you would need/want to run something on the Streamers computer itself and relay that information to your extension.
Thanks for your help!
And then I use the hlsLatencyBroadcaster to sync the data right? Or is there any other value that I need to have consideration?
That value tells you the delay for the user using your extension. (ignoring manually set stream delay or OBS delay)
