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

    • The above documentation
    • Presentations
    • Examples and test results (hyperlink to Monty's demo, gmaxwell's HA results page, etc)
