Method Details

compareUnsigned

public static int compareUnsigned(long x,
 long y)

TODO replace with Long.compareUnsigned(long, long)

Method is a copy of Long.compareUnsigned(long, long), which is available only since 1.8

Compares two long values numerically treating the values as unsigned.

Parameters:

x - the first long to compare

y - the second long to compare

Returns:

the value 0 if x == y; a value less than 0 if x < y as unsigned values; and a value greater than 0 if x > y as unsigned values

convertTimestamp

public static long convertTimestamp(long pts,
 Rational timeBaseFrom,
 Rational timeBaseTo)

Converts passed in PTS from one timebase to another.

This method is equivalent to (ln*sn)/(d1*d2)

Parameters:

pts - pts in timeBaseFrom

timeBaseFrom - pts timebase

timeBaseTo - timebase to switch to

Returns:

converted PTS
