* Add codecs to librbcodec.Sean Bartell2012-04-25
| | | | | | | Change-Id: Id7f4717d51ed02d67cb9f9cb3c0ada4a81843f97 Reviewed-on: http://gerrit.rockbox.org/137 Reviewed-by: Nils Wallménius <nils@rockbox.org> Tested-by: Nils Wallménius <nils@rockbox.org>
* FS#12231Nils Wallménius2011-08-18
| | | | | | | | | | | | | | | | | 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
* FS#12141 by Sean BartellNils Wallménius2011-06-02
| | | | | | | | | | | Some of these were found with http://www.samba.org/junkcode/#findstatic. Changes of note: * The old MDCT has been removed. * Makefile.test files that create test programs for libatrac, libcook, and libffmpegFLAC have been removed, as they don't work. My project will have a replacement that works with all codecs. * I've tried not to remove anything useful. CLIP_TO_15 was removed from libtremor because there's another copy (also commented) in codeclib. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@29945 a1c6a512-1295-4272-9138-f99709370657
