asf.h Initial, work-in-progress, version of a WMA codec using Michael Giacomelli's 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. 2007-07-03 09:25:36 +00:00
bitstream.c Fix warnings. 2007-07-13 01:41:31 +00:00
bitstream.h WMA codec: Coldfire is capable of unaligned memory accesses, so lets make use of it. ~1.5% speedup. 2007-07-12 22:12:25 +00:00
bswap.h WMA codec: Coldfire is capable of unaligned memory accesses, so lets make use of it. ~1.5% speedup. 2007-07-12 22:12:25 +00:00
ffmpeg_config.h WMA codec: Coldfire is capable of unaligned memory accesses, so lets make use of it. ~1.5% speedup. 2007-07-12 22:12:25 +00:00
Makefile WMA codec: Coldfire is capable of unaligned memory accesses, so lets make use of it. ~1.5% speedup. 2007-07-12 22:12:25 +00:00
SOURCES Fix the above by including all required files and updating SOURCES. 2007-07-12 03:26:20 +00:00
wmadata.h Add incomplete support for files using noise coding but not LSP. In practice, this means files >= 20kbps will probably work, and those below will probably not. 2007-07-20 21:36:54 +00:00
wmadec.h Add incomplete support for files using noise coding but not LSP. In practice, this means files >= 20kbps will probably work, and those below will probably not. 2007-07-20 21:36:54 +00:00
wmadeci.c Fix overflow in noise coding. Greatly improves sound quality of some low bitrate files 2007-07-25 02:34:21 +00:00
wmafixed.c Sync the bitstream functions with ffmpeg. Switch wmadeci.c over to get_vlc2 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. 2007-07-12 03:17:19 +00:00
