* Minor optimization for musepack codec through moving functions to IRAM on PP ↵Andree Buschmann2010-03-11
| | | | | | processors. Speed ups codec by 0.25 MHzon PP5022. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@25127 a1c6a512-1295-4272-9138-f99709370657
* Major change to musepack decoder: Import v1.3.0 (r458 from svn.musepack.net) ↵Andree Buschmann2010-03-07
| | | | | | to rockbox. Several adaptions in the musepack decoder were made to get the library work and perform fast under rockbox on several targets. With this change mpc sv8 is supported, including seek, replay gain and metadata support. The decoding speed is a 1-4% lower than the last implementation. Reason for this is main restructuring in the bitstream demuxer. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@25056 a1c6a512-1295-4272-9138-f99709370657
* Solve possible glitch after seeking in mpc files. Documented the special ↵Andree Buschmann2008-06-28
| | | | | | treatment after seek. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@17829 a1c6a512-1295-4272-9138-f99709370657
* Further changes in mpc buffered seek. Remove magical number and replace it ↵Andree Buschmann2008-06-04
| | | | | | with a better commented #define. Use shift and bit mask instead of division and modulo operations when using the seek buffer. Saves some binary size for the codec. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@17686 a1c6a512-1295-4272-9138-f99709370657
* Fix for FS#9054. MPC-playback stopped after 3:34min caused by out-of-bounds ↵Andree Buschmann2008-05-31

* Fixes backward seeking on resumed files and backward seeking to positions to ↵Andree Buschmann2008-05-22
| | | | | | which formerly was seeked forward to (sounds complicated and it is). git-svn-id: svn://svn.rockbox.org/rockbox/trunk@17606 a1c6a512-1295-4272-9138-f99709370657
* Commit FS#9015. Rework of musepack buffered seek. Now a static seek buffer ↵Andree Buschmann2008-05-22
| | | | | | of 8192 entries is used. The seeking precision is adapted to the length of the file (e.g. 26ms for files <=3.5min and 0.4s for files ~60min). git-svn-id: svn://svn.rockbox.org/rockbox/trunk@17604 a1c6a512-1295-4272-9138-f99709370657
* Musepack seek hotfix. Do not dynamically allocate seek buffer but use a ↵Andree Buschmann2008-05-19
| | | | | | buffer of constant size (~28.5min). Files larger than this will still not seek properly. Some additional rework has to be done for the seek buffer. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@17584 a1c6a512-1295-4272-9138-f99709370657
* Musepack performance optimization for PP5022/PP5024/MCF5250 targets. Use ↵Andree Buschmann2008-05-14
| | | | | | IRAM for internal sample buffers and lookup tables. Speeds up decoding by ~7% on PP5022/PP5024 (Sansa: c200, e200 + iPod mini2G, nano, video) and by ~27% on MCF5250 (iaudio m5, x5). git-svn-id: svn://svn.rockbox.org/rockbox/trunk@17507 a1c6a512-1295-4272-9138-f99709370657

* Some changes for musepack: Disable SV4-SV6 support (I guess I am the only ↵Andree Buschmann2008-05-10
| | | | | | one who oned such). Remove tabs, perform some minor code beautification and add ICONST_ATTR to some requantization constants. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@17438 a1c6a512-1295-4272-9138-f99709370657

Note that this should not fix the track change *pop* because there still seems to be a problem decoding the first and last several hundred samples of MPC files. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@8306 a1c6a512-1295-4272-9138-f99709370657
