Function Documentation

int av_parse_video_rate	(	AVRational *	rate,
		const char *	str
	)

Parse str and store the detected values in *rate.

Parameters:

[in,out]	rate	pointer to the AVRational which will contain the detected frame rate
[in]	str	the string to parse: it has to be a string in the format rate_num / rate_den, a float number or a valid video rate abbreviation

Returns:

>= 0 on success, a negative error code otherwise

int av_parse_video_size	(	int *	width_ptr,
		int *	height_ptr,
		const char *	str
	)

Parse str and put in width_ptr and height_ptr the detected values.

Parameters:

[in,out]	width_ptr	pointer to the variable which will contain the detected width value
[in,out]	height_ptr	pointer to the variable which will contain the detected height value
[in]	str	the string to parse: it has to be a string in the format width x height or a valid video size abbreviation.

Returns:

>= 0 on success, a negative error code otherwise
