VideoStreamPerf

Here’s an App Store-style English app description:

VideoStreamPerf is a professional macOS utility for evaluating real-time camera and video stream performance with clear, practical metrics.

Designed for developers, QA engineers, hardware testers, and video workflow teams, the app helps you measure how different cameras and streaming configurations behave under real conditions. You can monitor real-time FPS, average FPS, 1% Low FPS, frame interval stability, and smoothness to quickly identify dropped frames, jitter, and performance bottlenecks.

Create and compare multiple test scenes with different devices, resolutions, formats, and frame rate settings. Built-in visual charts make it easy to understand performance trends over time, while export features let you save detailed results as PDF or CSV for reporting, analysis, or team collaboration.

Key features:

Measure real-time camera stream performance on macOS
Track FPS, frame intervals, and smoothness metrics
Compare devices and streaming configurations side by side
Visualize live and recorded performance data with charts
Export test reports in PDF and CSV formats
Focus on analysis only, with no video recording or storage
Whether you are validating hardware performance, tuning a capture pipeline, or investigating stream quality issues, MacVideoStreamPerf provides a fast and focused way to turn live camera data into actionable insights.
