|

* <refsect2>
|
||||
* <para>
|
||||
* The progressreport element can be put into a pipeline to report progress,
|
||||
* which is done by doing upstream duration and position queries in regular
|
||||
* (real-time) intervals. Both the interval and the prefered query format
|
||||
* can be specified via the "update-freq" and the "format" property.
|
||||
* </para>
|
||||
* <para>
|
||||
* Element messages containing a "progress" structure are posted on the bus
|
||||
* whenever progress has been queried (since gst-plugins-good 0.10.6 only).
|
||||
* </para>
|
||||
* <para>
|
||||
* Since the element was originally designed for debugging purposes, it will
|
||||
* by default also print information about the current progress to the
|
||||
* terminal. This can be prevented by setting the "silent" property to TRUE.
|
||||
* </para>
|
||||
* <para>
|
||||
* This element is most useful in transcoding pipelines or other situations
|
||||
* where just querying the pipeline might not lead to the wanted result. For
|
||||
* progress in TIME format, the element is best placed in a 'raw stream'
|
||||
* section of the pipeline (or after any demuxers/decoders/parsers).

||||
