1* implement A/52a downmix extensions 2* use restrict pointers where appropriate 3* reduce size of delay buffer by 50% 4 5* get rid of globals in bitstream parsing 6* get rid of statics in imdct.c 7* avoid overflows, including reading the a52 stream !!! 8* make dither code faster (generate dither table in advance ?) 9* redo all bit allocation if previous frame had zero_snr_offsets 10* make dynrng work in dual-channel streams 11 12* update bitstream code 13
