2008-06-28Solve possible glitch after seeking in mpc files. Documented the special ↵Andree Buschmann
treatment after seek. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@17829 a1c6a512-1295-4272-9138-f99709370657
2008-06-04Further changes in mpc buffered seek. Remove magical number and replace it ↵Andree Buschmann
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
2008-05-31Fix for FS#9054. MPC-playback stopped after 3:34min caused by out-of-bounds ↵Andree Buschmann
access. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@17671 a1c6a512-1295-4272-9138-f99709370657
2008-05-22Fixes backward seeking on resumed files and backward seeking to positions to ↵Andree Buschmann
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
2008-05-22Commit FS#9015. Rework of musepack buffered seek. Now a static seek buffer ↵Andree Buschmann
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
2008-05-19Musepack seek hotfix. Do not dynamically allocate seek buffer but use a ↵Andree Buschmann
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
2008-05-14Musepack performance optimization for PP5022/PP5024/MCF5250 targets. Use ↵Andree Buschmann
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

2008-05-10Some changes for musepack: Disable SV4-SV6 support (I guess I am the only ↵Andree Buschmann
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

2006-04-29Fix the first-frame memmove from pretending the data is interleaved, which ↵Thom Johansen
it isn't anymore. This should fix all remaining gapless problems with Musepack. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@9827 a1c6a512-1295-4272-9138-f99709370657

2006-01-08I figured out what was *really* causing the MPC track-change noise, so IDave Bryant
backed out Thom's change and made the appropriate change. 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
