Timecode class

Some parts have been copied / inspired by the pytimecode library by Joshua Banton

Notes: *There is a 24 hour SMPTE Timecode limit, so if your time exceeds that limit, it will roll over.

Timecode Does all the calculation over frames, so the main data it holds is frames, then when required it converts the frames to a timecode by using the frame rate setting.

Note: Drop frame timecodes operate by reporting higher frame numbers than really exist so that 29.97 timecodes stay in sync with 30 fps ones, etc.

Drop Frame Example:

at 29.97 fps, the next frame after 00:00:59;29 will be 00:01:00;02 (skipping 0 & 1) See the document here: https://www.connect.ecuad.ca/~mrose/pdf_documents/timecode.pdf

Drop Frame Calculations are done by implementing code found here:

Constructors

Timecode({TimecodeFramerate? framerate, int startFrames = 0}): Creates a new Timecode instance.
Timecode.atSeconds(double seconds, {TimecodeFramerate? framerate}): Creates a timecode at a specific number of seconds with a specified framerate.
factory
Timecode.atTimecode(String timecodeString, {TimecodeFramerate? framerate}): Creates a timecode with a specific timecode string and framerate.
factory

Methods

addFrames(int n) → void
back() → void
divFrames(int n) → void
multFrames(int n) → void
next() → void
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
subFrames(int n) → void
toString() → String: A string representation of this object.
override

Operators

operator *(int multiplier) → Timecode
operator +(Timecode other) → Timecode
operator -(Timecode other) → Timecode
operator /(int divisor) → Timecode
operator <(Timecode other) → dynamic
operator ==(Object other) → bool: The equality operator.
override
operator >(Timecode other) → dynamic

Static Methods

parseToFrames(String timecodeString, {TimecodeFramerate? framerate}) → int: The default format for a timecodeString is HH:MM:SS:FF where FF stands for the number of frames after the current second and may be 0 <= FF < fps.
