Abstract class for global clocks

## NAME

GStreamer::Clock -  Abstract class for global clocks

## HIERARCHY

```
  Glib::Object
  +----GStreamer::Object
       +----GStreamer::Clock
```

## METHODS

### clockid = $clock-\>new\_periodic\_id ($start\_time, $interval)

- •

  `$start_time` (unsigned integer)

- •

  `$interval` (unsigned integer)

### clockid = $clock-\>new\_single\_shot\_id ($time)

- •

  `$time` (unsigned integer)

### list = $clock-\>add\_observation ($slave, $master)

- •

  `$slave` (unsigned integer)

- •

  `$master` (unsigned integer)

### unsigned integer = $clock-\>adjust\_unlocked ($internal)

- •

  `$internal` (unsigned integer)

### (internal, external, rate\_num, rate\_denom) = $clock-\>get\_calibration

### $clock-\>set\_calibration ($internal, $external, $rate\_num, $rate\_denom)

- •

  `$internal` (unsigned integer)

- •

  `$external` (unsigned integer)

- •

  `$rate_num` (unsigned integer)

- •

  `$rate_denom` (unsigned integer)

### unsigned integer = $clock-\>get\_internal\_time

### clock or undef = $clock-\>get\_master

### boolean = $clock-\>set\_master ($master)

- •

  `$master` (GStreamer::Clock)

### 64 bit unsigned = $clock-\>get\_resolution

### 64 bit unsigned = $clock-\>set\_resolution ($resolution)

- •

  `$resolution` (64 bit unsigned)

### unsigned integer = $clock-\>get\_time

## PROPERTIES

- 'stats' (boolean : default false : readable / writable / private)

  Enable clock stats (unimplemented)

- 'timeout' (Glib::UInt64 : default 100000000 : readable / writable / private)

  The amount of time, in nanoseconds, to sample master and slave clocks

- 'window-size' (integer : default 32 : readable / writable / private)

  The size of the window used to calculate rate and offset

- 'window-threshold' (integer : default 4 : readable / writable / private)

  The threshold to start calculating rate and offset
