Description
Opus is a totally open, royalty-free, highly versatile audio codec.
It is standardized by the Internet Engineering Task Force (IETF)
as RFC 6716 which incorporated technology from Skype's SILK codec
and Xiph.Org's CELT codec.

Opus is designed to handle a wide range of interactive audio
applications, including Voice over IP, videoconferencing, in-game
chat, and even live, distributed music performances. It scales from
low bitrate narrowband speech at 6 kbit/s to very high quality
stereo music at 510 kbit/s. Opus uses both Linear Prediction (LP)
and the Modified Discrete Cosine Transform (MDCT) to achieve good
compression of both speech and music.

Log message:
Update to 1.1.4: A specially-crafted Opus packet could cause an
integer wrap-around in the SILK LSF stabilization code.
Reported as CVE-2017-0381, but upstream does not believe that any
remote code execution is possible.

Don't enable audio/opus' fixed-point code on arm; in the current version
the asm code requires EABI. Retain as a commented-out section as a hint
for future review. Problem reported by Jan Stary, ok naddy@
