Contents

Code

For IETF draft

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

SILK issues

  • PLC buffer not fully initialized (fix needs verifying)
  • Mid and side using different sampling rates (fix needs verifying)
  • Reduce SILK bandwidth switching artefacts
  • CLANG ARITHMETIC UNDEFINED at <silk/silk_NSQ_del_dec.c, (652:33)> : Op: *, Reason : Signed Multiplication Overflow, BINARY OPERATION: left (int32): 90005 right (int32): -25578

  • Find_poly improvements
  • silk warning: comparison is always true due to limited range of data type with assert
  • Fatal (internal) error in silk/encode_indices.c, line 189: assertion failed: ( psIndices->contourIndex < 34 && psEncC->fs_kHz > 8 && psEncC->nb_subfr == 4 ) || ( psIndices->contourIndex < 11 && psEncC->fs_kHz == 8 && psEncC->nb_subfr == 4 ) || ( psIndices->contourIndex < 12 && psEncC->fs_kHz > 8 && psEncC->nb_subfr == 2 ) || ( psIndices->contourIndex < 3 && psEncC->fs_kHz == 8 && psEncC->nb_subfr == 2 )
  • Fatal (internal) error in silk/encode_indices.c, line 130: assertion failed: psEncC->useInterpolatedNLSFs == 1 || psIndices->NLSFInterpCoef_Q2 == ( 1 << 2 )
  • Fatal (internal) error in silk/encode_indices.c, line 209: assertion failed: psIndices->LTPIndex[ k ] >= 0 && psIndices->LTPIndex[ k ] < ( 8 << psIndices->PERIndex )
  • Activity interface / silk_toc (currently unreachable)

Later

  • Exposed CELT constrained VBR
  • Fixed-point build
  • Fix build system (right now it fails to build shared libraries, drops .o files all over)
  • Floating point API
  • 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
  • Test vectors
  • Listening tests
  • Documentation (at a minimum every exported symbol should have complete and accurate documentation)
  • Add content to opus-codec.org
  • Oggz-validate (should also validate opus toc)
    • The above documentation
    • Presentations
    • Examples and test results (hyperlink to Monty's demo, gmaxwell's HA results page, etc)
  • Useful example software (e.g. streaming software that works correctly) (opus-tools in xiph git)
    • Support for resampling in tools

Third party software

  • Support in ekiga
  • Support in mumble
  • Support in asterisk
  • Support in firefox (rtcweb and in ogg)
  • Support in VLC
  • Support in ogg123
  • Support in ffmpeg
  • Support in rockbox
  • Support in foobar2000
  • Support in gstreamer
