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~~
Review Tim's "LSB with no pulses" fix

~~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

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~~
