24 * SECTION:element-progressreport
26 * The progressreport element can be put into a pipeline to report progress,
27 * which is done by doing upstream duration and position queries in regular
28 * (real-time) intervals. Both the interval and the prefered query format
29 * can be specified via the #GstProgressReport:update-freq and the
30 * #GstProgressReport:format property.
32 * Element messages containing a "progress" structure are posted on the bus
33 * whenever progress has been queried (since gst-plugins-good 0.10.6 only).
35 * Since the element was originally designed for debugging purposes, it will
36 * by default also print information about the current progress to the
37 * terminal. This can be prevented by setting the #GstProgressReport:silent
40 * This element is most useful in transcoding pipelines or other situations
41 * where just querying the pipeline might not lead to the wanted result. For
42 * progress in TIME format, the element is best placed in a 'raw stream'
43 * section of the pipeline (or after any demuxers/decoders/parsers).
45 * Three more things should be pointed out: firstly, the element will only
46 * query progress when data flow happens. If data flow is stalled for some
47 * reason, no progress messages will be posted. Secondly, there are other
48 * elements (like qtdemux, for example) that may also post "progress" element
49 * messages on the bus. Applications should check the source of any element
50 * messages they receive, if needed. Finally, applications should not take
51 * action on receiving notification of progress being 100%, they should only
52 * take action when they receive an EOS message (since the progress reported
53 * is in reference to an internal point of a pipeline and not the pipeline as
