Code
For IETF draft
- Code cleanup (any left?)
- Multi-channel signalling (done, needs more testing)
SILK issues
- PLC buffer not fully initialized (fix needs verifying)
- Mid and side using different sampling rates (fix needs verifying)
LLBR stereo issue (has a proposed fix)Introduces prefill bug (fixed on greg's tree)
- Artefacts on SILK mono<->stereo switching
- Artefacts on SILK frame size switching (e.g. 960,480 glitches)
Use of signed overflow (undefined in C), intentionally and otherwise.- Encoder triggers DTX randomly (even if not enabled) for 40/60 ms stereo frames
- 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
- Same in NSQ.c: line 408
- Same in decode_core.c: line 152
- Review Tim's "LSB with no pulses" fix
Later
Exposed CELT constrained VBRFixed-point buildFix 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)
