Comment (by tkalliom):

 The option -hwaccel nvdec works without errors. However, something is off,
 as decoding (e.g. throwing rawvideo to /dev/null) is actually ~15%
 _slower_ than on CPU...

 Also, the documentation seems to be lacking. ffmpeg -hwaccels gives cuvid
 but no nvdec, the manpage mentions only vdpau, and hwaccel_output_format
 is only mentioned on wikipages regarding VAAPI.
