What software can I use on 2nd PC to trigger sounds on streamed video?

01/09/2026 06:36 Moinnt#1
I would like to stream game video to a second PC running software which will provide sound cues to help me play the streamed game. I would like to play a sound if a health bar is low, or if a particular icon appears or disappears, or if text appears on the screen. I am not looking for any any communications back to the game PC (no mackcu etc).

Does anyone have a recommendation for existing software or service that can help with this without me creating my own Amazon Rekognition application?

Thanks!

honestly haven't seen any software that does exactly what you're describing out of the box. most of the "game helper" tools are either cheating-related (which you said you're not trying to do) or just not smart enough to read HUD elements like health bars.

your best bet is probably python + opencv. sounds more complicated than it is. you can find scripts online that just watch a specific region of the screen for color changes and play a sound when it happens. like if health bar turns red below 20%, trigger a .wav. no AI needed, just pixel watching.

there's also autoit or autohotkey if you wanna go the macro route. they have pixel search functions so you can check if a certain color appears/disappears and react to it. bit janky but works.

if you really don't wanna code, maybe check if obs + some plugin can do it? like scene changes based on color source? not sure if that exists but worth a look.

either way you're probably gonna have to DIY it a bit. but it's doable without building a whole rekognition app 👍
