+ *
+ * Sets or merges caps on a stream's buffers. That is, a buffer's caps are
+ * updated using (fields of) #GstCapsSetter:caps. Note that this may contain
+ * multiple structures (though not likely recommended), but each of these must
+ * be fixed (or will otherwise be rejected).
+ *
+ * If #GstCapsSetter:join is %TRUE, then the incoming caps' mime-type is
+ * compared to the mime-type(s) of provided caps and only matching structure(s)
+ * are considered for updating.
+ *
+ * If #GstCapsSetter:replace is %TRUE, then any caps update is preceded by
+ * clearing existing fields, making provided fields (as a whole) replace
+ * incoming ones. Otherwise, no clearing is performed, in which case provided
+ * fields are added/merged onto incoming caps
+ *
+ * Although this element might mainly serve as debug helper,
+ * it can also practically be used to correct a faulty pixel-aspect-ratio,
+ * or to modify a yuv fourcc value to effectively swap chroma components or such
+ * alike.

+/**
+ * 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 #GstProgressReport:update-freq and the
+ * #GstProgressReport: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 #GstProgressReport: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).
+ *
+ * <refsect2>
+ * <title>Example launch line</title>

+ * gst-launch-1.0 -m filesrc location=foo.ogg ! decodebin ! progressreport update-freq=1 ! audioconvert ! audioresample ! autoaudiosink
