Details

enum GstRTSPRangeUnit

typedef enum
{
  GST_RTSP_RANGE_SMPTE,
  GST_RTSP_RANGE_SMPTE_30_DROP,
  GST_RTSP_RANGE_SMPTE_25,
  GST_RTSP_RANGE_NPT,
  GST_RTSP_RANGE_CLOCK
} GstRTSPRangeUnit;

Different possible time range units.

`GST_RTSP_RANGE_SMPTE`	SMPTE timecode
`GST_RTSP_RANGE_SMPTE_30_DROP`	29.97 frames per second
`GST_RTSP_RANGE_SMPTE_25`	25 frames per second
`GST_RTSP_RANGE_NPT`	Normal play time
`GST_RTSP_RANGE_CLOCK`	Absolute time expressed as ISO 8601 timestamps

struct GstRTSPTimeRange

struct GstRTSPTimeRange {
  GstRTSPRangeUnit unit;

  GstRTSPTime min;
  GstRTSPTime max;
};

A time range.

GstRTSPRangeUnit `unit`;	the time units used
GstRTSPTime `min`;	the minimum interval
GstRTSPTime `max`;	the maximum interval

struct GstRTSPTime

struct GstRTSPTime {
  GstRTSPTimeType type;
  gdouble         seconds;
};

A time indication.

GstRTSPTimeType `type`;	the time of the time
gdouble `seconds`;	seconds when `type` is GST_RTSP_TIME_SECONDS

enum GstRTSPTimeType

typedef enum {
  GST_RTSP_TIME_SECONDS,
  GST_RTSP_TIME_NOW,
  GST_RTSP_TIME_END
} GstRTSPTimeType;

Possible time types.

`GST_RTSP_TIME_SECONDS`	seconds
`GST_RTSP_TIME_NOW`	now
`GST_RTSP_TIME_END`	end

gst_rtsp_range_parse ()

GstRTSPResult       gst_rtsp_range_parse                (const gchar *rangestr,
                                                         GstRTSPTimeRange **range);

Parse rangestr to a GstRTSPTimeRange.

`rangestr` :	a range string to parse
`range` :	location to hold the GstRTSPTimeRange result
Returns :	GST_RTSP_OK on success.

gst_rtsp_range_to_string ()

gchar *             gst_rtsp_range_to_string            (const GstRTSPTimeRange *range);

Convert range into a string representation.

`range` :	a GstRTSPTimeRange
Returns :	The string representation of `range`. `g_free()` after usage.

Since 0.10.23

gst_rtsp_range_free ()

void                gst_rtsp_range_free                 (GstRTSPTimeRange *range);

Free the memory alocated by range.
