# 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 preferred query format can be specified via the update-freq and the 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 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).

## Example launch line

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

This shows a progress query where a duration is available.

     gst-launch-1.0 -m audiotestsrc ! progressreport update-freq=1 ! audioconvert ! autoaudiosink

This shows a progress query where no duration is available.
