2009-08-16	revert r22337 for libwma for now since it broke wma playback on ARM due to ↵	Mohamed Tarek
	alignment issues. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@22347 a1c6a512-1295-4272-9138-f99709370657
2009-08-15	Move bitstream.[ch] to codecs/lib/ffmpeg_bitstream.[ch] to avoid duplicate ↵	Mohamed Tarek
	copies across codecs. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@22337 a1c6a512-1295-4272-9138-f99709370657
2008-09-04	Combine the Vorbis, WMA and AAC IMDCT functions and put them into the ↵	Michael Giacomelli
	codeclib. Combined IMDCT is now based on existing Tremor transform. Reduces CPU for 192k AAC by 21MHz on Coldfire, and 5MHz on PP5024. WMA and Vorbis should have no functional changes since they already used this code. Further optimization is possible and would benefit all 3 codecs. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@18412 a1c6a512-1295-4272-9138-f99709370657
2008-07-17	Use Tremor IMDCT for WMA. Gives a ~20% speedup on ARM and coldfire. All my ↵	Michael Giacomelli
	test samples gave equivilent or better accuracy (>>16 bit), but there may still be problems. Code becomes somewhat less readable since the IMDCT has bits of Vorbis in it, but this is not a serious issue and the old ffmpeg transform remains in SVN if anyone wants it. Also, WMA now passes Vorbis as the fastest transform codec on ARM, although MPC remains the fastest lossy codec overall. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@18084 a1c6a512-1295-4272-9138-f99709370657
2007-09-20	move (i)MDCT and FFT code to separate files	Marcoen Hirschberg
	git-svn-id: svn://svn.rockbox.org/rockbox/trunk@14776 a1c6a512-1295-4272-9138-f99709370657
2007-07-12	Fix the above by including all required files and updating SOURCES.	Michael Giacomelli
	git-svn-id: svn://svn.rockbox.org/rockbox/trunk@13860 a1c6a512-1295-4272-9138-f99709370657
2007-07-12	Sync the bitstream functions with ffmpeg. Switch wmadeci.c over to get_vlc2 ↵	Michael Giacomelli
	which is how ffmpeg now does it and is also slightly faster. Add in defines for later VLC memory usage optization. Kill some header files that weren't needed and update others that were out of sync. We're now much closer to the current ffmpeg codec which should make fixing the remaining issues much easier. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@13859 a1c6a512-1295-4272-9138-f99709370657
2007-07-04	Attempt #2	Michael Giacomelli
	git-svn-id: svn://svn.rockbox.org/rockbox/trunk@13786 a1c6a512-1295-4272-9138-f99709370657
2007-07-04	Code clean up: Move fixed point functions into their own files. Move ↵	Michael Giacomelli
	various lookup tables into header files. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@13784 a1c6a512-1295-4272-9138-f99709370657
2007-07-03	Initial, work-in-progress, version of a WMA codec using Michael Giacomelli's ↵	Dave Chapman
	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
