I need a console-based Python application that will: • Open the computer’s webcam, capture exactly 15 seconds of footage, and save the result as an MP4 in the working directory. • Immediately play the freshly recorded clip in a lightweight window while a second window renders a live decibel-level graph of the same audio track. • Treat either window as a play/pause toggle—mouse click or a simple keypress should pause and resume both streams in perfect sync. Because the interface must stay console-friendly, I do not want a full desktop GUI. Using OpenCV, ffmpeg-python, moviepy, pyaudio, matplotlib, curses, or any mix you prefer is fine as long as the final script runs cross-platform with a clean requirements.txt. Deliverables • main.py (self-contained, clear functions) • Any companion modules or assets • requirements.txt with pinned versions • README with setup and usage steps Acceptance test: after running `python main.py`, the webcam starts, an MP4 appears when recording ends, two playback windows open side-by-side, and either window pauses/resumes both video and graph on demand.
