- svq1enc: remove stale altivec-related hack · 0e55edcb
  Mans Rullgard authored Nov 26, 2011
```
altivec.h is no longer (indirectly) included, so this hack is not
needed.

- adx: rename ff_adx_decode_header() to avpriv_adx_decode_header() · 9d2dd356
  Justin Ruggles authored Nov 26, 2011
```
It is used by the ADX decoder, and therefore needs to be exported in order to
work with shared libs.

- adx: add an ADX parser. · 27360ccc
  Justin Ruggles authored Nov 21, 2011
```
This simplifies the decoder so it doesn't have to process an in-packet header
or handle arbitrary-sized packets. It also fixes decoding of files with large
headers.

- adx: calculate correct LPC coeffs · b237248e
  Justin Ruggles authored Nov 20, 2011
```
Instead of using fixed coefficients, the correct way is to calculate the
coefficients using the highpass cutoff frequency from the ADX stream header
and the sample rate.

This multiplication can overflow the signed range but not the
unsigned.  After right-shifting it will thus fit in the signed
range again.
