## Description

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.

This element can perform simple frame dropping with the “drop-factor” property. Setting this property to a value N > 1 will only decode every Nth frame.

### Example launch line

    1
    gst-launch-1.0 filesrc location=test.dv ! dvdemux name=demux ! dvdec ! xvimagesink

This pipeline decodes and renders the raw DV stream to a videosink.
