- Enable camera at startup with error handling (was never called) - Add missing return in camera.get_frame() success path (was returning None, causing black screen) - Wrap PyAudio init in whitenoise with try/except to prevent hangs - Add 15s timeout to quick_speed_test() to prevent startup blockage - Fix whitenoise __close method (recursion and attribute bugs) - Create media/audio directory if missing
pip install pyaudio from source requires portaudio.h (from portaudio19-dev). Also add python3-dev for build tools and enable --system-site-packages in the venv so system-installed packages (picamera2, etc.) are accessible.

Summary
Fixes camera not showing live feed, startup hangs on headless systems, and missing build dependencies for ARM64.
Changes
🎥 Camera: Enable at startup + fix black screen
Files:
src/main.py,src/controllers/camera.pyCameraControllerwas instantiated butenable()was never called —get_frame()always returned a noise/black fallback frame. Addedcamera.enable()with error handling at startup.get_frame()had noreturnin the success path of the try/except block. Whencapture_array()succeeded, the function returnedNoneimplicitly, causing a black screen in the WebRTC video track.🔊 WhiteNoisePlayer: Handle missing audio hardware
File:
src/controllers/whitenoise.pypyaudio.PyAudio()called without error handling hangs indefinitely on systems without working audio (e.g. headless Raspberry Pi). Wrapped in try/except soself.pisNoneon failure.hasattr(self, 'stream')guards to preventAttributeErrorwhen__openSpeaker()was never called or failed.__close()method that had infinite recursion (stop()→__close()→stop()) and accessedself.streamafter closing.⏱ Speed test: Add timeout to prevent startup hang
File:
src/utils.pyquick_speed_test()usesspeedtest-cliwhich can hang indefinitely on networks with no internet or poor connectivity. Wrapped the test in aThreadPoolExecutorwith a 15-second timeout so the server starts regardless.📦 packages.txt: Add build deps for ARM64
File:
src/packages.txtpyaudiofails topip installon aarch64 becauseportaudio.his missing. Addedportaudio19-dev(headers) andpython3-dev(build tools) so the C extension compiles successfully.
