| <a name="gst-plugins-good-plugins-progressreport.description"></a><h2>Description</h2> |
| <p>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 <a class="link" href="gst-plugins-good-plugins-progressreport.html#GstProgressReport--update-freq" title="The “update-freq” property"><span class="type">“update-freq”</span></a> and the |
| <a class="link" href="gst-plugins-good-plugins-progressreport.html#GstProgressReport--format" title="The “format” property"><span class="type">“format”</span></a> property.</p> |
| <p>Element messages containing a "progress" structure are posted on the bus |
| whenever progress has been queried (since gst-plugins-good 0.10.6 only).</p> |
| <p>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 <a class="link" href="gst-plugins-good-plugins-progressreport.html#GstProgressReport--silent" title="The “silent” property"><span class="type">“silent”</span></a> |
| property to <a href="/usr/share/gtk-doc/html/glibglib-Standard-Macros.html#TRUE:CAPS"><code class="literal">TRUE</code></a>.</p> |
| <p>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).</p> |
| <p>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).</p> |
