| <p>GStreamer elements can throw non-fatal warnings and fatal errors. |
| Higher-level elements and applications can programmatically filter |
| the ones they are interested in or can recover from, |
| and have a default handler handle the rest of them.</p> |
| <p>The rest of this section will use the term <span class="quote">“<span class="quote">error</span>”</span> |
| to mean both (non-fatal) warnings and (fatal) errors; they are treated |
| similarly.</p> |
| <p>Errors from elements are the combination of a <a href="https://developer.gnome.org/glib/unstable/glib-Error-Reporting.html#GError"><span class="type">GError</span></a> and a debug string. |
| The <a href="https://developer.gnome.org/glib/unstable/glib-Error-Reporting.html#GError"><span class="type">GError</span></a> contains:</p> |
| <div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; "> |
| <li class="listitem"><p>a domain type: CORE, LIBRARY, RESOURCE or STREAM</p></li> |
| <li class="listitem"><p>a code: an enum value specific to the domain</p></li> |
| <li class="listitem"><p>a translated, human-readable message</p></li> |
| <li class="listitem"><p>a non-translated additional debug string, which also contains</p></li> |
| <li class="listitem"><p>file and line information</p></li> |
| </ul></div> |
| <p>Elements do not have the context required to decide what to do with |
| errors. As such, they should only inform about errors, and stop their |
| processing. In short, an element doesn't know what it is being used for.</p> |
| <p>It is the application or compound element using the given element that |
| has more context about the use of the element. Errors can be received by |
| listening to the <a class="link" href="GstBus.html" title="GstBus"><span class="type">GstBus</span></a> of the element/pipeline for <a class="link" href="GstMessage.html" title="GstMessage"><span class="type">GstMessage</span></a> objects with |
| the type <a class="link" href="GstMessage.html#GST-MESSAGE-ERROR:CAPS"><code class="literal">GST_MESSAGE_ERROR</code></a> or <a class="link" href="GstMessage.html#GST-MESSAGE-WARNING:CAPS"><code class="literal">GST_MESSAGE_WARNING</code></a>. The thrown errors should |
| be inspected, and filtered if appropriate.</p> |
| <p>An application is expected to, by default, present the user with a |
| dialog box (or an equivalent) showing the error message. The dialog |
| should also allow a way to get at the additional debug information, |
| so the user can provide bug reporting information.</p> |
| <p>A compound element is expected to forward errors by default higher up |
| the hierarchy; this is done by default in the same way as for other types |
| of <a class="link" href="GstMessage.html" title="GstMessage"><span class="type">GstMessage</span></a>.</p> |
| <p>When applications or compound elements trigger errors that they can |
| recover from, they can filter out these errors and take appropriate action. |
| For example, an application that gets an error from xvimagesink |
| that indicates all XVideo ports are taken, the application can attempt |
| to use another sink instead.</p> |
| <p>Elements throw errors using the <a class="link" href="GstElement.html#GST-ELEMENT-ERROR:CAPS" title="GST_ELEMENT_ERROR()"><span class="type">GST_ELEMENT_ERROR</span></a> convenience macro:</p> |

| this keeps messages more uniform. Use (<a href="https://developer.gnome.org/glib/unstable/glib-Standard-Macros.html#NULL:CAPS"><code class="literal">NULL</code></a>) - not forgetting the |
| parentheses.</p></li> |
| <li class="listitem"><p>If you do supply a custom message, it should be |

| A user interface will present this message as the first thing a user |
