arrayBinarySearch void* arrayBinarySearch(void* array, uint numElements, size_t elementSize, GCompareDataFunc searchFunc, GstSearchMode mode, void* searchData, void* userData): Searches inside @array for @search_data by using the comparison function @search_func. @array must be sorted ascending.
doubleToFraction void doubleToFraction(double src, int destN, int destD): Transforms a #gdouble to a fraction and simplifies the result.
dumpMem void dumpMem(char* mem, uint size): Dumps the memory block into a hex representation. Useful for debugging.
fractionAdd bool fractionAdd(int aN, int aD, int bN, int bD, int resN, int resD): Adds the fractions @a_n/@a_d and @b_n/@b_d and stores the result in @res_n and @res_d.
fractionCompare int fractionCompare(int aN, int aD, int bN, int bD): Compares the fractions @a_n/@a_d and @b_n/@b_d and returns -1 if a < b, 0 if a = b and 1 if a > b.
fractionMultiply bool fractionMultiply(int aN, int aD, int bN, int bD, int resN, int resD): Multiplies the fractions @a_n/@a_d and @b_n/@b_d and stores the result in @res_n and @res_d.
fractionToDouble void fractionToDouble(int srcN, int srcD, double dest): Transforms a fraction to a #gdouble.
gdoubleToGuint64 ulong gdoubleToGuint64(double value)
getTimestamp GstClockTime getTimestamp(): Get a timestamp as GstClockTime to be used for interval measurements. The timestamp should not be interpreted in any other way.
greatestCommonDivisor int greatestCommonDivisor(int a, int b): Calculates the greatest common divisor of @a and @b.
greatestCommonDivisorInt64 long greatestCommonDivisorInt64(long a, long b): Calculates the greatest common divisor of @a and @b.
groupIdNext uint groupIdNext(): Return a constantly incrementing group id.
guint64ToGdouble double guint64ToGdouble(ulong value)
seqnumCompare int seqnumCompare(uint s1, uint s2): Compare two sequence numbers, handling wraparound.
seqnumNext uint seqnumNext(): Return a constantly incrementing sequence number.
setObjectArg void setObjectArg(ObjectG object, string name, string value): Converts the string value to the type of the objects argument and sets the argument with it.
setValueFromString void setValueFromString(Value value, string valueStr): Converts the string to the type of the value and sets the value with it.
uint64Scale ulong uint64Scale(ulong val, ulong num, ulong denom): Scale @val by the rational number @num / @denom, avoiding overflows and underflows and without loss of precision.
uint64ScaleCeil ulong uint64ScaleCeil(ulong val, ulong num, ulong denom): Scale @val by the rational number @num / @denom, avoiding overflows and underflows and without loss of precision.
uint64ScaleInt ulong uint64ScaleInt(ulong val, int num, int denom): Scale @val by the rational number @num / @denom, avoiding overflows and underflows and without loss of precision. @num must be non-negative and @denom must be positive.
uint64ScaleIntCeil ulong uint64ScaleIntCeil(ulong val, int num, int denom): Scale @val by the rational number @num / @denom, avoiding overflows and underflows and without loss of precision. @num must be non-negative and @denom must be positive.
uint64ScaleIntRound ulong uint64ScaleIntRound(ulong val, int num, int denom): Scale @val by the rational number @num / @denom, avoiding overflows and underflows and without loss of precision. @num must be non-negative and @denom must be positive.
uint64ScaleRound ulong uint64ScaleRound(ulong val, ulong num, ulong denom): Scale @val by the rational number @num / @denom, avoiding overflows and underflows and without loss of precision.
