Removed

• Drop Python 3.6 support.

Fixed

• Linux: Close opened devices if device is not given (#59)

Removed

• RGBA support has been removed. Use RGB instead.

0.5.0

Added

• Linux: multiple camera support (#37).
• If print_fps=True and Camera.sleep_until_next_frame() is used, the percentage of time spent in computation is printed in addition to fps.

Changed

• macOS/Windows: raise error if OBS virtual camera is not installed.

Fixed

• macOS: camera was not correctly cleaned up after use (#39).
• macOS: an error is now raised if the camera is already in use outside of the current process (#39).

Fixed

• Sending a frame with incorrect width or height now raises an exception instead of crashing (#17).
