"clamp-chroma" gboolean : Read / Write "clamp-luma" gboolean : Read / Write "drop-factor" gint : Read / Write "quality" GstDVDecQualityEnum : Read / Write
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.
