Function Documentation

double av_expr_eval	(	AVExpr *	e,
		const double *	const_values,
		void *	opaque
	)

Evaluate a previously parsed expression.

Parameters

const_values	a zero terminated array of values for the identifiers from av_expr_parse() const_names
opaque	a pointer which will be passed to all functions from funcs1 and funcs2

Returns

the value of the expression

void av_expr_free

(

AVExpr *

e

)

Free a parsed expression previously created with av_expr_parse().

int av_expr_parse	(	AVExpr **	expr,
		const char *	s,
		const char *const *	const_names,
		const char *const *	func1_names,
		double(**)(void *, double)	funcs1,
		const char *const *	func2_names,
		double(**)(void *, double, double)	funcs2,
		int	log_offset,
		void *	log_ctx
	)

Parse an expression.

Parameters

expr	a pointer where is put an AVExpr containing the parsed value in case of successful parsing, or NULL otherwise. The pointed to AVExpr must be freed with av_expr_free() by the user when it is not needed anymore.
s	expression as a zero terminated string, for example "1+2^3+5*5+sin(2/3)"
const_names	NULL terminated array of zero terminated strings of constant identifiers, for example {"PI", "E", 0}
func1_names	NULL terminated array of zero terminated strings of funcs1 identifiers
funcs1	NULL terminated array of function pointers for functions which take 1 argument
func2_names	NULL terminated array of zero terminated strings of funcs2 identifiers
funcs2	NULL terminated array of function pointers for functions which take 2 arguments
log_ctx	parent logging context

Returns

0 in case of success, a negative value corresponding to an AVERROR code otherwise

int av_expr_parse_and_eval	(	double *	res,
		const char *	s,
		const char *const *	const_names,
		const double *	const_values,
		const char *const *	func1_names,
		double(**)(void *, double)	funcs1,
		const char *const *	func2_names,
		double(**)(void *, double, double)	funcs2,
		void *	opaque,
		int	log_offset,
		void *	log_ctx
	)

Parse and evaluate an expression.

Note, this is significantly slower than av_expr_eval().

Parameters

res	a pointer to a double where is put the result value of the expression, or NAN in case of error
s	expression as a zero terminated string, for example "1+2^3+5*5+sin(2/3)"
const_names	NULL terminated array of zero terminated strings of constant identifiers, for example {"PI", "E", 0}
const_values	a zero terminated array of values for the identifiers from const_names
func1_names	NULL terminated array of zero terminated strings of funcs1 identifiers
funcs1	NULL terminated array of function pointers for functions which take 1 argument
func2_names	NULL terminated array of zero terminated strings of funcs2 identifiers
funcs2	NULL terminated array of function pointers for functions which take 2 arguments
opaque	a pointer which will be passed to all functions from funcs1 and funcs2
log_ctx	parent logging context

Returns

0 in case of success, a negative value corresponding to an AVERROR code otherwise

double av_strtod	(	const char *	numstr,
		char **	tail
	)

Parse the string in numstr and return its value as a double.

If the string is empty, contains only whitespaces, or does not contain an initial substring that has the expected syntax for a floating-point number, no conversion is performed. In this case, returns a value of zero and the value returned in tail is the value of numstr.

Parameters

numstr	a string representing a number, may contain one of the International System number postfixes, for example 'K', 'M', 'G'. If 'i' is appended after the postfix, powers of 2 are used instead of powers of 10. The 'B' postfix multiplies the value for 8, and can be appended after another postfix or used alone. This allows using for example 'KB', 'MiB', 'G' and 'B' as postfix.
tail	if non-NULL puts here the pointer to the char next after the last parsed character
