Priority: medium
Bug ID: 58824
Assignee: spice-bugs at lists.freedesktop.org
Summary: Replace Celt with Opus
Severity: normal
Classification: Unclassified
OS: All
Reporter: bugs at kerrickstaley.com
Hardware: Other
Status: NEW
Version: unspecified
Component: protocol
Product: Spice
Spice depends on Celt 0.5.1, which is very old (0.5.2 came out almost 5 years
ago [1]). Opus [2] is an IETF-standardized codec that supersedes Celt. It's
annoying for package maintainers to support Celt 0.5.1 alongside later versions
of Celt and Opus, and this is helping to prevent Arch Linux from including
Spice in its official repositories [3].
I'm guessing libopus doesn't support Celt 0.5.1's older bitstream format, so
this fix isn't quite trivial: something will have to be done to address older
clients interacting with newer servers and vice versa.
