int av_parse_color | ( | uint8_t * | rgba_color, | |
const char * | color_string, | |||
int | slen, | |||
void * | log_ctx | |||
) |
Put the RGBA values that correspond to color_string in rgba_color.
color_string | a string specifying a color. It can be the name of a color (case insensitive match) or a [0x|#]RRGGBB[AA] sequence, possibly followed by "@" and a string representing the alpha component. The alpha component may be a string composed by "0x" followed by an hexadecimal number or a decimal number between 0.0 and 1.0, which represents the opacity value (0x00/0.0 means completely transparent, 0xff/1.0 completely opaque). If the alpha component is not specified then 0xff is assumed. The string "random" will result in a random color. | |
slen | length of the initial part of color_string containing the color. It can be set to -1 if color_string is a null terminated string containing nothing else than the color. |

int av_parse_time | ( | int64_t * | timeval, | |
const char * | timestr, | |||
int | duration | |||
) |
Parses timestr and returns in *time a corresponding number of microseconds.
timeval | puts here the number of microseconds corresponding to the string in timestr. If the string represents a duration, it is the number of microseconds contained in the time interval. If the string is a date, is the number of microseconds since 1st of January, 1970 up to the time of the parsed date. If timestr cannot be successfully parsed, set *time to INT64_MIN. | |
datestr | a string representing a date or a duration.
| |
duration | flag which tells how to interpret timestr, if not zero timestr is interpreted as a duration, otherwise as a date |

int av_parse_video_rate | ( | AVRational * | rate, | |

Parse str and store the detected values in *rate.
[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 |
