Different possible time range units.
struct GstRTSPTimeRange { GstRTSPRangeUnit unit; GstRTSPTime min; GstRTSPTime max; GstRTSPTime2 min2; GstRTSPTime2 max2; };
A time range.
GstRTSPRangeUnit |
the time units used |
GstRTSPTime |
the minimum interval |
GstRTSPTime |
the maximum interval |
GstRTSPTime2 |
extra fields in the minimum interval (Since: 1.2) |
GstRTSPTime2 |
extra fields in the maximum interval (Since: 1.2) |
struct GstRTSPTime { GstRTSPTimeType type; gdouble seconds; };
A time indication.
GstRTSPTimeType |
the time of the time |
seconds when type is GST_RTSP_TIME_SECONDS,
GST_RTSP_TIME_UTC and GST_RTSP_TIME_FRAMES |
struct GstRTSPTime2 { gdouble frames; guint year; guint month; guint day; };
Extra fields for a time indication.
frames and subframes when type in GstRTSPTime is GST_RTSP_TIME_FRAMES | |
year when type is GST_RTSP_TIME_UTC | |
month when type is GST_RTSP_TIME_UTC | |

Since 1.2
typedef enum { GST_RTSP_TIME_SECONDS, GST_RTSP_TIME_NOW, GST_RTSP_TIME_END, GST_RTSP_TIME_FRAMES, GST_RTSP_TIME_UTC } GstRTSPTimeType;
Possible time types.
GstRTSPResult gst_rtsp_range_parse (const gchar *rangestr
,GstRTSPTimeRange **range
);
Parse rangestr
to a GstRTSPTimeRange.
|
a range string to parse |
|
location to hold the GstRTSPTimeRange result |
Returns : |
GST_RTSP_OK on success. |
gboolean gst_rtsp_range_get_times (const GstRTSPTimeRange *range
,GstClockTime *min
,GstClockTime *max
);
Retrieve the minimum and maximum values from range
converted to
GstClockTime in min
and max
.
A value of GST_CLOCK_TIME_NONE
will be used to signal GST_RTSP_TIME_NOW
and GST_RTSP_TIME_END for min
and max
respectively.
UTC times will be converted to nanoseconds since 1900.
|
a GstRTSPTimeRange |
|
result minimum GstClockTime |
|
result maximum GstClockTime |
Returns : |
TRUE on success. |
Since 1.2
gchar * gst_rtsp_range_to_string (const GstRTSPTimeRange *range
);
Convert range
into a string representation.
|
a GstRTSPTimeRange |
Returns : |
The string representation of range . g_free() after usage. |
gboolean gst_rtsp_range_convert_units (GstRTSPTimeRange *range
,GstRTSPRangeUnit unit
);
Converts the range in-place between different types of units. Ranges containing the special value GST_RTSP_TIME_NOW can not be converted as these are only valid for GST_RTSP_RANGE_NPT.
|
a GstRTSPTimeRange |
|
the unit to convert the range into |
Returns : |
TRUE if the range could be converted |
void gst_rtsp_range_free (GstRTSPTimeRange *range
);
Free the memory allocated by range
.
