public static String millisecondsToString(long milliseconds)

Deprecated.

please use #toTimecode() instead.

Convert milliseconds to "hh:mm:ss.ms" String representation.

Parameters:

milliseconds - time duration in milliseconds

Returns:

time duration in human-readable format

toTimecode

public static String toTimecode(long duration,
 TimeUnit units)

Convert the duration to "hh:mm:ss" timecode representation, where ss (seconds) can be decimal.

Parameters:

duration - the duration.

units - the unit the duration is in.

Returns:

the timecode representation.

millisToSeconds

public static String millisToSeconds(long millis)

Converts milliseconds to a seconds string representation. Uses integer format when there are no fractional seconds, otherwise uses decimal format with up to 3 decimal places and trailing zeros removed.

Parameters:

millis - duration in milliseconds

Returns:

seconds as a string (e.g. "5", "0.005", "1.5")

fromTimecode

public static long fromTimecode(String time)

Returns the number of nanoseconds this timecode represents. The string is expected to be in the format "hour:minute:second", where second can be a decimal number.

Parameters:

time - the timecode to parse.

Returns:

the number of nanoseconds or -1 if time is 'N/A'

parseBitrate

public static long parseBitrate(String bitrate)

Converts a string representation of bitrate to a long of bits per second.

Parameters:

bitrate - in the form of 12.3kbits/s

Returns:

the bitrate in bits per second or -1 if bitrate is 'N/A'
