* Reorganise the wma_decode_superframe() function - split into a separate init ↵Dave Chapman2007-07-09

Each call to the decode function now decodes a single frame (2048 samples) instead of an entire superframe (which typically contained about 7 or 8 frames and can in theory contain up to 16 frames). This allows us to replace the 256KB output buffer with a 8KB buffer, and also perform more yields in the main decoding loop. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@13833 a1c6a512-1295-4272-9138-f99709370657

fixed-point and malloc-less WMA decoder (based on the ffmpeg WMA decoder from early 2006, and also building on the work started by Paul Jones). The codec itself and the ASF parsing code were written by me, inspired by the ASF parser in libasf. Current performance is around 400% realtime on gigabeat, 100% realtime on PP and 20% realtime on Coldfire. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@13769 a1c6a512-1295-4272-9138-f99709370657
