| <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="/usr/share/gtk-doc/html/glibglib-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="/usr/share/gtk-doc/html/glibglib-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> |
