I wonder if use of -itsoffset is incompatible with -vcodec copy?
Your source material is long GOP mpeg and you wish to start with an
offset, I can see why that might be an issue. What happens if you try
the command without the -itsoffset?
What happens if you specify an output codec?
what happens if you specify both an audio and video codec?

Try changing one thing at a time and see what effect that has.
