Code

For IETF draft

• Multi-channel signalling (done, needs more testing)
• Make opus-compare fail for single seriously trashed frames?

Later

• Usable command-line tools (opus is a major regression from libcelt right now)
• Smart automatic mode decision
• psymodel based VBR
• Remove copy in inverse MDCT
• Save some float<->int conversions

Spec

• Finish codec draft
• Ogg mapping (including multi-channel). See: OggOpus
• RTP payload format

Other

• Logo See: Mozilla bug 689261 for some discussion
• Test vectors
• Listening tests
• Documentation (at a minimum every exported symbol should have complete and accurate documentation)
• Add content to opus-codec.org
  • The above documentation
  • Presentations
  • Examples and test results (hyperlink to Monty's demo, gmaxwell's HA results page, etc)
• Oggz-validate (should also validate opus toc)

Opus-tools

• Build infrastructure (e.g. autotools)
• A simple real time streaming example tool
• Multichannel support doneish.
• Replaygain (half done— needs a gain tool)
• Testing (incl. jenkins automation) doneish
