<a name="gst-plugins-bad-plugins-jpegparse.description"></a><h2>Description</h2>
<p>Parses a JPEG stream into JPEG images. It looks for EOI boundaries to
split a continuous stream into single-frame buffers. Also reads the
image header searching for image properties such as width and height
among others. Jpegparse can also extract metadata (e.g. xmp).</p>

<div class="informalexample"><pre class="programlisting">
gst-launch -v souphttpsrc location=... ! jpegparse ! matroskamux ! filesink location=...
</pre></div>
The above pipeline fetches a motion JPEG stream from an IP camera over
HTTP and stores it in a matroska file.
