## Member Function Documentation

## ◆ create()

static Glib::RefPtr<Gst::MessageStepDone> Gst::MessageStepDone::create | ( | const Glib::RefPtr< Gst::Object >& | src,
|  | Gst::Format | format,
|  | guint64 | amount,
|  | double | rate,
|  | bool | flush,
|  | bool | intermediate,
|  | guint64 | duration,
|  | bool | eos
| ) |  |
| static

This message is posted by elements when they complete a part, when intermediate set to `true`, or a complete step operation.

duration will contain the amount of time (in GST_FORMAT_TIME) of the stepped amount of media in format format.

Parameters

  src | The object originating the message.
  format | The format of amount.
  amount | The amount of stepped data.
  rate | The rate of the stepped amount.
  flush | Is this an flushing step.
  intermediate | Is this an intermediate step.
  duration | The duration of the data.
  eos | The step caused EOS.

Returns
  The new step_done message.

MT safe.

## ◆ parse()

void Gst::MessageStepDone::parse | ( | Gst::Format& | format,
|  | guint64 & | amount,
|  | double & | rate,
|  | bool & | flush,
|  | bool & | intermediate,
|  | guint64 & | duration,
|  | bool & | eos
| ) |  | const

Extract the values of the step done message.

MT safe.

Parameters

  format | Result location for the format.
  amount | Result location for the amount.
  rate | Result location for the rate.
  flush | Result location for the flush flag.
  intermediate | Result location for the intermediate flag.
  duration | Result location for the duration.
  eos | Result location for the EOS flag.

Since 0.10.24.
