* Call rdft by function pointerMåns Rullgård2010-03-201-1/+6
| | | | | | | | | Call the RDFT by a function pointer like other FFT related transforms. This makes instruction set optimized versions possible. Based on patch by Alex Converse. Originally committed as revision 22609 to svn://svn.ffmpeg.org/ffmpeg/trunk
