Set metadata information of the next output file from @var{infile}. Note that
those are file indices (zero-based), not filenames.
Optional @var{metadata_type} parameters specify, which metadata to copy - (g)lobal
(i.e. metadata that applies to the whole file), per-(s)tream, per-(c)hapter or
per-(p)rogram. All metadata specifiers other than global must be followed by the
stream/chapter/program index. If metadata specifier is omitted, it defaults to
global.
Optional @var{metadata_spec_in/out} parameters specify, which metadata to copy.
A metadata specifier can have the following forms:
