So I turned on QSV support and I get this in my log:

21:57:28: QSV version 1.6 using MFX_IMPL_HARDWARE_ANY | MFX_IMPL_VIA_D3D11 (actual: MFX_IMPL_HARDWARE2 | MFX_IMPL_VIA_D3D11)

21:57:29: Error: all encode tasks in use, stalling pipeline

Shortly after that the stream freezes.

Any chance that the R2 release of the 2013 Media SDK fixed this bug?

Please provide the full logfile. Also make sure you're using the latest graphics drivers from Intel.

You may have to setup a monitor for the IGPU, for some reason the DX11 mode doesn't work properly for everyone.
