Synchronised with opus repo on github (https://github.com/freqmod/rockbox-opus) Status: * Seeking ported from speex, but fails on some cases (e.g. seek to granule 0) * ReplayGain parsing needs to be reworked, we do vorbis-style replaygain now. http://wiki.xiph.org/OggOpus#Comment_Header explicitly forbids these in favour of R128_TRACK_GAIN tag. * No optimisation yet, source files still nearly identical to opus upstream * Multi-stream opus files may not be parsed correctly Change-Id: Ia66f1027dc1d288083e3c57b2816700078376f9a Reviewed-on: http://gerrit.rockbox.org/300 Reviewed-by: Bertrik Sikken <bertrik@sikken.nl> Tested-by: Bertrik Sikken <bertrik@sikken.nl>
