Support for "real-time" write to shared memory

[wizzar]

I'm just starting out with OBS, the plugins and whatnot.

I'm wondering if it would be possible to output the source to the shared memory region whenever it is updated/repainted instead of doing it every X milleseconds, or lowering the 0.25 limit.

I've looked everywhere for something like streaming to a shared memory, hooking the function that draws the source image, etc... but found nothing. Your plugin is what comes the closest to this.

whenever it is updated/repainted

I would do this by running the plugin every frame and checking for changes (there might be an API or you could use some hash - maybe ask on the OBS discord).
You could change the tick logic that decides whether to capture here

lowering the 0.25 limit

Edit this with your lower limit (and recompile)

The only concern will be that OBS has about 16ms delay for any streaming method expect for game capture (if succeeded)
