/**
|
||||
* SECTION:element-progressreport
|
||||
*
|
||||
* 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 #GstCpuReport:update-freq and the
|
||||
* #GstCpuReport:format property.
|
||||
*
|
||||
* Element messages containing a "progress" structure are posted on the bus
|
||||
* whenever progress has been queried (since gst-plugins-good 0.10.6 only).
|
||||
*
|
||||
* 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 #GstCpuReport:silent
|
||||
* property to %TRUE.
|
||||
*
|
||||
* 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).
|
||||
*
|
||||
* Three more things should be pointed out: firstly, the element will only
|
||||
* query progress when data flow happens. If data flow is stalled for some
|
||||
* reason, no progress messages will be posted. Secondly, there are other
|
||||
* elements (like qtdemux, for example) that may also post "progress" element
|
||||
* messages on the bus. Applications should check the source of any element
|
||||
* messages they receive, if needed. Finally, applications should not take
|
||||
* action on receiving notification of progress being 100%, they should only
|
||||
* take action when they receive an EOS message (since the progress reported
|
||||
* is in reference to an internal point of a pipeline and not the pipeline as
|
||||
* a whole).

||||
