From 7d485f165f7f6313002da1fe67c2742f0fbb16c9 Mon Sep 17 00:00:00 2001 From: Siarhei Siamashka Date: Sat, 16 May 2009 14:17:08 +0000 Subject: Support for getting (i)MDCT output multiplied by a constant scaling factor. Scaling (i)MDCT output has no runtime overhead and can be used to improve performance of audio codecs. All the changes are only needed in 'ff_mdct_init' function and slow down initialization a bit.
