1. A method comprising:
creating one or more prefix indications in or along a bitstream;
including, in the one or more prefix indications, an initial part of an information message, wherein the information message describes one or more post-filtering operations or related information, and wherein the initial part describes one or more post-filter properties;
using the one or more prefix indications to declare the one or more post-filter properties of the bitstream so as to enable selection of the bitstream to be received or decoded;
making the one or more prefix indications accessible through a media description describing the bitstream, wherein the one or more prefix indications are contained in at least one of the following:
one or more media parameters in the media description; or
one or more syntax elements or one or more syntax structures in a file encapsulating the bitstream, wherein the file is accessible via the media description.
