| | 1 | = Proposed roadmap for Musepack = |
| | 2 | |
| | 3 | == 1. Code cleanup and restructuration == |
| | 4 | a. Split mppenc in 3 parts :[[br]] no nead to be able to compile mppenc, but libs must compile and have clear entry points and structs |
| | 5 | * libmpcpsy (name ?) for the psyco-acoustic model |
| | 6 | * libmpcenc for qmf filtering, quantization , entropy coding and stream formating |
| | 7 | * mppenc (mpcenc ? name ?) for command line utility |
| | 8 | b. Make a minimal mppenc using libmpcenc and lipmpcpsy and .wav input (from another lib ?). Encoding must be the same as 1.15w bit for bit (without tags). |
| | 9 | c. Code cleanup : |
| | 10 | * rewrite mppenc from old code and use libs as much as possible (taglib, ...) |
| | 11 | * code cleanup : remove all unused / commented code, look for duplicated code, use fftw lib for libmpcpsy |
| | 12 | |
| | 13 | == 2. First sv8 steps == |
| | 14 | * write sv8 needs and start a specification |
| | 15 | * add sv8 to libmpcenc / libmpcdec |
| | 16 | * create an utility to convert sv7 => sv8 using libmpcdec / libmpcenc |
| | 17 | * maybe release sv8.0 at this point |
| | 18 | * put sv8 frames into other containers (mkv) |
| | 19 | * try to improve entropy coding of current stream. release sv8.1 if successful, update the convert utility |
| | 20 | |
| | 21 | == 3. Improving sv8, the incompatible way == |
| | 22 | untill this point, conversion from from sv7 to sv8 was lossless. |
| | 23 | * Improve lipmpcpsy if possible (doesn't break compatibility, but make old encodes obsolete) |
| | 24 | * Change core compression : make use of transform, state of the art compression tools. This time compatibility is totaly broken. Once done release sv8.2 ? |
