    7878If you have a video capture card (ex: !AverMedia, possibly some !BlackMagic, though it may be a separate unrelated problem, and also some !BlackMagic cards don't have the right inputs set up ask on the forum), it may not work (yet) out of the box with FFmpeg, as it lacks crossbar support presently.  The work around currently is to install the AmerecTV software, which presents the capture card as directshow devices, then input the AmerecTV directshow devices into your FFmpeg.  See [http://www.ffsplit.com/forums/showthread.php?422-Filter-How-to-use-a-capture-card-with-AmarecTV here].
