No. The default is the VLC for local files, and lavf for the rest.

If neither lavf nor VLC can parse the file, I don't really see how falling back 
would help.

The clean solution is to fix both demuxers, or get the VLC demuxer to support 
non-local files and fix it, or get the lavf demuxer on the feature level of the 
VLC one and fix it. Good luck with that.
