The opusfile and opusurl libraries provide a high-level API for decoding and seeking within .opus files on disk or over http(s).
opusfile depends on libopus and libogg. opusurl depends on opusfile and openssl.
The library is functional, but there are likely issues we didn't find in our own testing. Please give feedback in #opus on irc.freenode.net or at opus@xiph.org.
Programming documentation is available in tree and online at https://opus-codec.org/docs/
