Issue: Low FPS when running OpenCV inference through WebSockets in Electron

[johnraivenolazo]

What I tried

Initially, I sent the OpenCV camera frames and inference results from Python → FastAPI → Electron using WebSockets.

Problem

The FPS dropped massively (video feed was barely moving).

The stream had noticeable lag/delay, making real-time inference unusable.

It seems WebSockets added too much overhead for continuous high-frame-rate video data.

Logs and small data still work fine through WebSockets, but video frames choke the pipeline.

Decision / Workaround

To fix this, I’m switching the real-time OpenCV inference to run directly via a child_process (Electron spawning Python).

im leaving this issue open for others who might run into the same bottleneck. WebSockets are great for events and small data, but not for continuous real-time video inference.
