I didn't find anything in the log. Looks like vlc or the underlying libraries failed to detect the hardware. Is this an NVIDIA Optimus-type setup that requires bumblebee to work properly?

I am using the Mesa drivers for both cards, as far as > OpenGL goes. (The proprietary NVidia drivers don't support being an output slave.) For the Intel card that'd be i965-va-driver (or intel-media-va-driver and setting LIBVA_DRIVER_NAME to iHD). You'll probably also need non-free firmware for that. For NVIDIA you'd need the non-free drivers together nvidia-vdpau-driver. As far as I am aware, the hardware decoding experience with nouveau is suboptimal. Cheers -- Sebastian Ramacher
