Create a new duration message.
This message is posted by elements that know the duration of a stream in a specific format. This message is received by bins and is used to calculate the total duration of a pipeline. Elements may post a duration message with a duration of Gst::CLOCK_TIME_NONE to indicate that the duration has changed and the cached duration should be discarded. The new duration can then be retrieved via a query.
| src | The object originating the message. | 
| format | The format of the duration. | 
| duration | The new duration. | 
| void Gst::MessageDuration::parse | ( | Format& | format, | 
| gint64 & | duration | ||
| ) | const | 
Extracts the duration and format from the duration message.
The duration might be Gst::CLOCK_TIME_NONE, which indicates that the duration has changed. Applications should always use a query to retrieve the duration of a pipeline.
