USBCam v1.1.2

Fixed

• Update check no longer shows a false "new version available" message. The app now reads its version from the APK manifest (matches Settings > Apps), so it always matches what GitHub reports.
• The Download button in the update dialog now opens the latest APK file directly instead of the releases page.
• AndroidManifest versionName/versionCode are now kept in sync (1.1.2 / 3).

Download

• Android: usbcam.apk below (Android 8.0+)
• Windows: use USBCam.exe from v1.0.0 (unchanged)

USBCam v1.1.1 - stable 30 fps

New in v1.1.1

• Stable 30 fps: the camera sensor is now pinned to a constant 30 fps range, so the frame rate no longer drops in low light (was 10-15 fps on some devices, now a steady 30)
• Smarter JPEG quality: quality scales with resolution - 4K frames shrank ~2.3 MB to ~1 MB, freeing USB bandwidth for a higher frame rate
