Coming from https://bugs.webkit.org/show_bug.cgi?id=162366#c44 I'd like to describe my use case: I am trying to create a video sampler where musicians or musically interested people can create short video loops (in the gist of audio loops in a traditional sampler) and share this with their peers. To achieve this, WebKit needs to be able to play simultaneous clips in a group of video elements. I don't think this needs to synced on a per frame base but that would be great of course. Thanks for looking into this. Best regards, Dirk
