* Add ff_ prefix to data symbols of encoders, decoders, hwaccel, parsers, bsf.Diego Elio Pettenò2011-01-26
| | | | | | | None of these symbols should be accessed directly, so declare them as hidden. Signed-off-by: Mans Rullgard <mans@mansr.com>

* Convert floating-point MDCT coefficients to 24-bit fixed-point all at onceJustin Ruggles2011-01-05
| | | | | | | | 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
* Change the AC-3 encoder to use floating-point.Justin Ruggles2011-01-04
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
