10-bit card is connected (screen shot: http://i.imgur.com/olYfm.jpg). And with
latest gst, and decklinksrc is loaded.


1) Problem how it looks: 

10-bit capture looks like this (screen shot): http://i.imgur.com/wR2jx.png

2) Latest gstreamer, by default it capture 8-bit only.

- Frame received [No timecode] - Valid Frame - Size: 1843200 bytes
- Where i was expecting 2488320 bytes.
- Manufacturer has a testing tools, where i can check with the -p option to
tell 8-bit or 10-bit capture. But with decklinksrc there is no -p option, it
always fall-back to 8-bit.


3) How do i capture 10-bit then?

- change bmdFormat8BitYUV to 10 and recompile and run gst-launch -v decklinksrc
... ! xvimagesink

- the line should look like this:

ret = decklinksrc->input->EnableVideoInput (mode->mode, bmdFormat10BitYUV, 0);


Does this gives enough information to render the problem?
