This source is pretty much necessary for me if i want to stream high quality video, since window capture in OSX is too taxing on the CPU. It's pretty limited in term of functionality though. You can pretty much just start a clip, pause/play until it ends. The latest patch made it possible to assign hotkeys to VLC Video Source which is cool, but for long clips it's pretty key to be able to jump to specific parts imo. I found this old thread talking about video controls for the VLC Video Source and I'm curious if there's any updates regarding this feature: https://obsproject.com/forum/threads/control-media-source-playback.27804/
