No Building an isolated-source video recording and streaming engine on macOS requires specialized low-level multimedia systems programming and GPU-accelerated video pipelines.
What it would actually take: The architecture requires tight integration with Apple's ScreenCaptureKit, AVFoundation, and VideoToolbox for hardware-accelerated H.264/HEVC encoding, paired with custom Metal shaders for multi-track composition. The primary engineering bottleneck is orchestrating concurrent multi-source (ISO) recording and live RTMP/SRT streaming without frame drops or audio-drift under heavy system load.
