<span>I'm working on making decklinksrc work on Windows, and can stream
to disk fine (at normal framerates, using composite NTSC source), but if i display to the screen (e.g. using dshowvideosink) the framerate drops to
something like 1fps. <br><br>What might be the cause of this?<br><br>FYI, DeckLink provides a COM interface, and I've copied the relevant bits from dshowvideosink for handling this.<br><br>Thanks,<br>-Josh<br></span>
