2011-08-18FS#12231Nils Wallménius
Centralize the selection of codec compilation flags to codec.make to avoid having to duplicate the per cpu selection logic and the build rule in the individual codec lib make files and make tweaking easier. The two special cases, libmad and libspeex were left alone. I plan to introduce a var for arm generation so that appropriate flags can be selected per generation as benchmarking results have shown that different arm arches might have different optimal flags. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@30330 a1c6a512-1295-4272-9138-f99709370657

2010-10-02Finally fix FS#11476 (data abort when playing some sv8 mpc files on lowmem ↵Andree Buschmann
targets like Clip+/Fuzev1/Fuzev2). This fix disables loading of seek tables from the sv8 bitstream. Those table are located at the end of sv8-files. When playing sv8 files this resulted in seek to filebegin, then fileend, then back to filebegin. Such seeking behaviour results in heavy rebuffering when playing files on targets with low RAM. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@28197 a1c6a512-1295-4272-9138-f99709370657

2010-03-07Major change to musepack decoder: Import v1.3.0 (r458 from svn.musepack.net) ↵Andree Buschmann
to rockbox. Several adaptions in the musepack decoder were made to get the library work and perform fast under rockbox on several targets.
