Well, it seems your cam creates a file that it claims to contain audio
but forgets to actually put any audio in.
You could try -dumpstream and see if that file has the same issue and
make that available to use.
You could also try -demuxer lavf.
Otherwise you will just have to use -nosound or get your camera
manufacturer to change their code to make it create files that make
sense, i.e. either
1) they claim to have audio and actually have audio or
2) they don't claim to have audio in the file when they actually don't.
