IMPORT DETAILS -The decoder is based on ffmpeg-svn r18079. It still uses floating -point math and not suitable to be used in rockbox. +The decoder is based on ffmpeg-svn r18079. +The decoder had been modified to use fixed-point arithmetic. TESTING The test program should compile in any Unix-like environment using the command "make -f Makefile.test". +For ARM targets add -DCPU_ARM to CFLAGS in Makefile.test to make use of +the asm ARM optimisations in rockbox's mdct library. + +For Big-endian targets, change -D"ROCKBOX_LITTLE_ENDIAN=1" +to -D"ROCKBOX_BIG_ENDIAN=1" in Makefile.test. + Running "./atractest file.rm" will decode the
