    6767See [http://ffmpeg.org/ffmpeg.html#dshow here] for a list of more dshow options you can specify, for instance you can decrease latency on audio devices, specify a video by "index" if 2 have the same name displayed, etc.

     71If you have a video capture card (ex: !BlackMagic), it may not work (yet) out of the box with !FFmpeg, as it lacks crossbar support.  The work around currently is to install the AmerecTV software, which presents the capture card as directshow devices, then input the AmerecTV devices into your FFmpeg instance.  See [http://www.ffsplit.com/forums/showthread.php?422-Filter-How-to-use-a-capture-card-with-AmarecTV here].

     75== !AviSynth Input == 
    7076 
    7177FFmpeg can also take !DirectShow input by creating an avisynth file (.avs file) that itself gets input from a graphedit file, which graphedit file exposes a pin of your capture source or any filter really, ex ("yo.avs"):

     82 
     83ffdshow tryouts is a separate project that basically wraps FFmpeg's core source (libavcodec, etc.) and then presents them as filter wrappers that your normal Windows applications can use for decoding video, etc.  It's not related to "ffmpeg.exe" directly, at all.
