Justin Ruggles	ac05f9030e	Convert floating-point MDCT coefficients to 24-bit fixed-point all at once ... instead of doing it separately in 2 different functions. This makes float AC-3 encoding approx. 3-7% faster overall. Also, the coefficient conversion can now be easily SIMD-optimized.

Justin Ruggles	6fd96d1a85	Change the AC-3 encoder to use floating-point. ... Fixed-point AC-3 encoder renamed to ac3_fixed. Regression test acodec-ac3 renamed to acodec-ac3_fixed. Regression test lavf-rm changed to use ac3_fixed encoder. Originally committed as revision 26209 to svn://svn.ffmpeg.org/ffmpeg/trunk	2011-01-04 11:53:44 +00:00
