2014-06-02COMMON: Use float constants in DCT code.Johannes Schickel
Makes the DCT code use constants of type float in expressions which only use type float values otherwise. This silences some floating point conversion warnings in the DCT code.
2014-02-18COMMON: Make GPL headers consistent in themselves.Johannes Schickel
2012-04-17COMMON: Update DCT & RDFT to avoid dynamic allocation of Sine/Cos Tables.D G Turner
2012-04-14COMMON: Replaced static Sine and Cosine tables with dynamic generated.D G Turner
This removes the large static tables from the binary (which saves 500K to 1Mb of binary size) and replaced them with a class which generates the required tables as needed in RAM. This has been tested with QDM2 and shows no obvious performance degredation and Memprof shows no significant rise in RAM usage.
2011-07-19COMMON: Fix some formattingMatthew Hoops
2011-07-19COMMON: Move cosine/sine tables out of header filesMatthew Hoops
Access is now restricted to using the getSineTable()/getCosineTable() helper functions.
2011-07-02COMMON: Add DCT math codeMatthew Hoops
Based on eos' code which is based on FFmpeg's code
