[FFmpeg-user] capture via decklink

Hi Guys,

I'm also doing this, but with GStreamer for the capture and ffmpeg for 
editing only.

For instance, to connect a YPbPr component source you can use:

     gst-launch decklinksrc mode=18 connection=3 ! videorate ! 
ffmpegcolorspace ! xvimagesink

     gst-inspect decklinksrc gives the other options.

It works, but it's still a bit problematic because of the variety of 
video standards for component video.

Actually, if you've got the hardware (ie SSD or RAID 0 x6), the HDMI 
connection works well too.  You can drop the video rate to 5fps, but 
that rather spoils the whole point of it.

decklinksrc is in the "ugly" plug-ins of 0.10, and I don't believe it 
has been upgrade to 1.0 yet.
