So, this nice program send AV stream to ffmpeg via pipe? And this is
known to have problems when you have to stream
1080p (it is about 1GBps of raw data).

This is why I'm speaking about ffmpeg internal code.

It wouldn't be that hard to add support to ffmpeg, though I'd write it with a threaded input driver.
libavdevice would be enough if you didn't care about fancy features like ancillary data.
There's already support for the v210 packing that the cards use in 10-bit mode.
