Good you attached the full log, because you cut the most relevant message:
[vdpau] Creating H264 hardware decoder for 4 reference frames.
[vdpau] Failed creating VDPAU decoder: The display was pre-empted, or a fatal error occurred.
So no, that is unlikely to be an out-of-memory issue, and you should create a log file with the VDPAU debug environment variables set as described in one of the stickies, because this is one for NVidia to look into IMO.
