If it played out and video is gone, just press Ctrl+Enter again and after that Shift + Q to quit output. To remove links between nodes use X to remove and also to remove node Shift+X. First need to select node/link with mouse. You can select more links/nodes at once in editor too.

This is super! Really nice to play with. I have trouble understanding one thing (perhaps I'm just not seeing it). Let me describe what i do, in case i am misunderstanding something. 1. Add a movie source and a buffersink. 2. set filename of movie source 3. control enter to configure, now a pad shows up at the movie source. 4. connect out pad of movie source to in pad of buffer sink 5. control enter to configure again, now a preview window shows up. 6. i play my file, things work. Great! 7. Now i want to add an actual filter in between. How do i do that? I can't seem to edit anything anymore once its configured/played, almost all options are grayed out. I tried exporting the filtergraph, restarting lavfi-preview and then importing the filter graph. This however directly brings me to the state after step 5 above, so again can't edit anything, only play. So more generally, how to preview and then edit the filter graph? Thanks!

This is super cool! It would be great if this becomes a sort of library/ImGui component. I (and i'm sure i'm not alone) have an application using ffmpeg libraries and already using ImGUI for the GUI, I'd love to be able to integrate this into it.
