<a name="gst-plugins-good-plugins-dvdec.description"></a><h2>Description</h2>
<p>dvdec decodes DV video into raw video. The element expects a full DV frame
as input, which is 120000 bytes for NTSC and 144000 for PAL video.</p>
<p>This element can perform simple frame dropping with the <a class="link" href="gst-plugins-good-plugins-dvdec.html#GstDVDec--drop-factor" title="The “drop-factor” property"><span class="type">“drop-factor”</span></a>
property. Setting this property to a value N > 1 will only decode every
Nth frame.</p>
