◆ parse_key_value_pair()

static int parse_key_value_pair	(	void *	ctx,
		const char **	buf,
		const char *	key_val_sep,
		const char *	pairs_sep
	)

static

Store the value in the field in ctx that is named like key.

ctx must be an AVClass context, storing is done using AVOptions.

Parameters

buf	the string to parse, buf will be updated to point at the separator just after the parsed key/value pair
key_val_sep	a 0-terminated list of characters used to separate key from value
pairs_sep	a 0-terminated list of characters used to separate two pairs from each other

Returns: 0 if the key/value pair has been successfully parsed and set, or a negative value corresponding to an AVERROR code in case of error: AVERROR(EINVAL) if the key/value pair cannot be parsed, the error code issued by av_opt_set() if the key/value pair cannot be set

◆ get_key()

static int get_key	(	const char **	ropts,
		const char *	delim,
		char **	rkey
	)

static

Read a key from a string.

The key consists of is_key_char characters and must be terminated by a character from the delim string; spaces are ignored.

Returns: 0 for success (even with ellipsis), <0 for failure
