When I right click a source, and select Filters, it brings up a window that only shows "Effect" filters. How do I bring up async filters?

There is no such thing as a "async filters" category. Some video sources such as video capture device have an additional category called "Audio/Video filters", and if you right-click an audio source in the audio mixer window and choose Filters, you get a category "Audio filters".

Async filters are in the source code, and they are mentioned in this thread:

https://obsproject.com/forum/threads/grabbing-frame-from-source-video-capture-device.48967/

I am having a problem right now where they are not appearing in the GUI anywhere and I'm unable to use them, even though the source code has two specific categories for "async" and "effect" filters

I had another thread on this topic but it was moved to the development forum:

https://obsproject.com/forum/threads/a-filter-that-can-read-pixel-data.110995/

However, right now I'm just trying to figure out where this feature is in the GUI in general

The filter you mention is available for video capture device sources, media sources, vlc media sources in the category "Audio/Video filters". It is called "Video Delay (async)" in the GUI. For most other capture sources, this category is not available and you can only use effect filters with them.

So if I just want to capture from my screen, then async filters are unavailable?

I just want to write a filter, or edit something in the source code somewhere, where I can get the per frame pixel data. I was trying to follow that post about async filters as a place to start

Hi, I'm just stumbling upon the same problem. Did you find any solution to this? I need realtime access to frame data on the gpu.
