<a name="gst-plugins-good-plugins-capssetter.description"></a><h2>Description</h2>
<p>Sets or merges caps on a stream's buffers. That is, a buffer's caps are
updated using (fields of) <a class="link" href="gst-plugins-good-plugins-capssetter.html#GstCapsSetter--caps" title="The “caps” property"><span class="type">“caps”</span></a>. Note that this may contain
multiple structures (though not likely recommended), but each of these must
be fixed (or will otherwise be rejected).</p>
<p>If <a class="link" href="gst-plugins-good-plugins-capssetter.html#GstCapsSetter--join" title="The “join” property"><span class="type">“join”</span></a> is <a href="../glib/glib-Standard-Macros.html#TRUE:CAPS"><code class="literal">TRUE</code></a>, 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.</p>
<p>If <a class="link" href="gst-plugins-good-plugins-capssetter.html#GstCapsSetter--replace" title="The “replace” property"><span class="type">“replace”</span></a> is <a href="../glib/glib-Standard-Macros.html#TRUE:CAPS"><code class="literal">TRUE</code></a>, 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</p>
<p>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.</p>
