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. All the best, Dee
Looks incredibly useful, will check it out. Later, z!

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! Dee

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. Use Shit - A to auto add sinks, so you do not need to do that quite boring task over and over again.

Super, that did the trick! I found some things while playing with lavfi-preview, I'll post issues in your repo. All the best, Dee
