- LCEVC filter - LCEVC filter
- MV-HEVC decoding - MV-HEVC decoding
- minor stream specifier syntax changes:
- when matching by metadata (:m:<key>:<val>), the colon character
in keys or values now has to be backslash-escaped
- in optional maps (-map ....?) with a metadata-matching stream specifier,
the value has to be separated from the question mark by a colon, i.e.
-map ....:m:<key>:<val>:? (otherwise it would be ambiguous whether the
question mark is a part of <val> or not)
- multiple stream types in a single specifier (e.g. :s:s:0) now cause an
error, as such a specifier makes no sense
