<p>
This element resizes video frames. By default the element will try to
negotiate to the same size on the source and sinkpad so that no scaling
is needed. It is therefore safe to insert this element in a pipeline to
get more robust behaviour without any cost if no scaling is needed.
</p>
<p>
This element supports a wide range of color spaces including various YUV and
RGB formats and is therefore generally able to operate anywhere in a
pipeline.
</p>
<p>
</p>
<div class="refsect2">
<a name="idp8085176"></a><h3>Example pipelines</h3>
<div class="informalexample"><pre class="programlisting">
gst-launch -v filesrc location=videotestsrc.ogg ! oggdemux ! theoradec ! ffmpegcolorspace ! videoscale ! ximagesink
</pre></div> Decode an Ogg/Theora and display the video using ximagesink. Since
ximagesink cannot perform scaling, the video scaling will be performed by
videoscale when you resize the video window.
To create the test Ogg/Theora file refer to the documentation of theoraenc.
<div class="informalexample"><pre class="programlisting">
gst-launch -v filesrc location=videotestsrc.ogg ! oggdemux ! theoradec ! videoscale ! video/x-raw-yuv, width=50 ! xvimagesink
</pre></div> Decode an Ogg/Theora and display the video using xvimagesink with a width
of 50.
