Add stereo rematrixing support to the AC-3 encoders.
This improves the audio quality significantly for stereo source with both the fixed-point and floating-point AC-3 encoders. Update acodec-ac3_fixed and seek-ac3_rm test references. Originally committed as revision 26271 to svn://svn.ffmpeg.org/ffmpeg/trunk |

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. Originally committed as revision 26232 to svn://svn.ffmpeg.org/ffmpeg/trunk |
