Parallelize FrameSource initialization with ThreadPoolExecutor#961
Conversation
Each FrameSource runs a keyframe scan on init, which is I/O-bound. With multiple cameras this was sequential, taking N × scan_time. Now all cameras initialize in parallel threads, reducing wall time to roughly the cost of the slowest single camera.
