Bug Fix

GuaranteedVideoWriter was joining a daemon - now changed to a normal thread.

GuaranteedVideoWriter

Added GuaranteedVideoWriter class for writing video with a guaranteed framerate that responds to the input/processing framerate. Repeats frames when input is too slow, and skips frames when input is too fast.

Package Bug Fix

Added __init__.py to pcv.examples to ensure the examples get included correctly when installed.

Organisation

• Bug fix when playing a video with unknown fps
• Refactored advanced examples to examples folder for cleaner navigation
• Added the cam_video_switcher example for multi-video reading with looping and webcam control.

VideoReader Convenience

• made verbose mode more meaningful (can now actually turn off messages about initial fps, etc)
• added a reset_delay function so external callbacks that pause playback can avoid rapid frame swapping/frame skipping on resume
• added a default callback for b to continue playback from the beginning (respects user-set start if set at initialisation)

Bug Fixes, Better Defaults

• removed a bug causing Camera instances to close on initialisation (#6)
• added exception handler for unsuccessful window close on context exit (doesn't really matter, so no need to end program)
• other minor internal changes

Timing + Module Naming

• Changed time.time to time.perf_counter for timing precision and cross-platform consistency
• Changed helpers.py to process.py to better reflect the intent of the functions

Restructure

Same functionality, but restructured into a few modules to make it easier to understand what comes from where, instead of everything coming from a generic pcv module. Introducing vidIO, interact, and helpers!

Functioning Pip

Pip-installable, and also runnable.
