Hum, it does indeed have a similar use case, but -skip_initial_bytes works
by discarding bytes before starting reading the file: it will only work with
files that are read sequentially. That excludes formats that have an index
at the end, and that excludes seeking.
With this protocol, you could open an AVI file in the middle of an TAR
archive and play it, including seeking.
