OBS crash (log included)

[llvs]

Hi all,

in order to help the devs, I want to post my crash log here.

I set everything up to capture my (single) display on the laptop (Win 8.1, nVidia 840M graphics) together with a webcam picture (Microsoft Lifecam HD) embedded on the top right.

Before the crash I had successfully recorded video and audio and OBS was stable. Between this and the crash I only changed two things:
- Canvas changed from 1280 to FullHD (display native resolution)
- Cropped the Webcam output using Alt+mouse drag on the edges

Recording is set to AAC LC audio and AVC video using nVidia NVENC.
