2010-03-14Separate DWT from snow and dsputilMåns Rullgård
This moves the DWT functions from snow.c and dsputil.c to a file of their own. A new struct, DWTContext, holds the function pointers previously part of DSPContext. Originally committed as revision 22522 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-03-11snow: remove unused stub functionsMåns Rullgård
w53_32_c() and w97_32_c() are defined as stubs when snow encoder is disabled. In this case, those functions are not referenced at all and do thus not need to be defined. Originally committed as revision 22448 to svn://svn.ffmpeg.org/ffmpeg/trunk

2008-08-31Globally rename the header inclusion guard names.Stefano Sabatini
Consistently apply this rule: the guard name is obtained from the filename by stripping the leading "lib", converting '/' and '.' to '_' and uppercasing the resulting name. Guard names in the root directory have to be prefixed by "FFMPEG_". Originally committed as revision 15120 to svn://svn.ffmpeg.org/ffmpeg/trunk
