Method Detail

av_malloc

com.sun.jna.Pointer av_malloc(int size)

av_realloc

com.sun.jna.Pointer av_realloc(com.sun.jna.Pointer ptr,
                               int size)

av_free

void av_free(com.sun.jna.Pointer ptr)

av_mallocz

com.sun.jna.Pointer av_mallocz(int size)

av_strdup

com.sun.jna.Pointer av_strdup(com.sun.jna.Pointer s)

av_freep

void av_freep(com.sun.jna.Pointer ptr)

av_rescale

long av_rescale(long a,
                long b,
                long c)

rescale a 64bit integer with rounding to nearest. a simple a*b/c isn't possible as it can overflow

av_rescale_rnd

long av_rescale_rnd(long a,
                    long b,
                    long c,
                    int rounding)

rescale a 64bit integer with specified rounding. a simple a*b/c isn't possible as it can overflow

av_reduce

int av_reduce(com.sun.jna.Pointer dst_nom,
              com.sun.jna.Pointer dst_den,
              long nom,
              long den,
              long max)

Reduce a fraction. This is useful for framerate calculations.

Parameters:

dst_nom - destination numerator

dst_den - destination denominator

nom - source numerator

den - source denominator

max - the maximum allowed for dst_nom & dst_den

Returns:

1 if exact, 0 otherwise

av_d2q

long av_d2q(double d,
            int max)

Converts a double precision floating point number to a rational.

Parameters:

d - double to convert

max - the maximum allowed numerator and denominator

Returns:

(AVRational) d.
