v1.2.1
Audio
- Add WASAPI loopback capture for Windows — auto-captures desktop audio (what's playing through speakers) without requiring Stereo Mix
- WASAPI backend uses
windowscrate COM APIs:IMMDeviceEnumerator→IAudioClient(loopback) →IAudioCaptureClient - Same fallback pattern as Linux: try WASAPI loopback first, fall back to cpal input devices
- Supports float32, int16, and int24 formats with stereo→mono downmix
- Device friendly name shown in status bar (e.g. "Speakers (Realtek Audio)")
Bug Fixes
- Fix webcam "Failed to fulfill requested format" on Windows: cameras that only support raw formats (YUYV/NV12) now work via automatic fallback from MJPEG to any supported format
CI
- Upload debug build artifacts on PRs for all platforms
