  68 dvdec decodes DV video into raw video. The element expects a full DV frame
  69 as input, which is 120000 bytes for NTSC and 144000 for PAL video.

  72 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>
