Diego Biurrun ebc701993f x86: dsputil: Drop some unused function #defines 2013-02-26 23:36:24 +01:00
Diego Biurrun 845cfc92f9 x86: dsputil: Drop aliasing of ff_put_pixels8_mmx to ff_put_pixels8_mmxext 
The external assembly function uses mmxext instructions and should not be
masqueraded as an mmx-only function. Instead, use the mmx-only inline
assembly function.

Luca Barbato 23bd9ef4b2 vorbisdec: Accept 0 amplitude_bits 
The specification does not prevent an encoder to write the amplitude 0
as 0 amplitude_bits.

Our get_bits() implementation might not support a zero sized read
properly, thus the additional branch.

Luca Barbato 5b47c19bfd vorbisdec: Add missing checks 
Rate and order must not be 0 even if the specification does not say that
explicitly.

Michael Niedermayer 11dcecfcca vorbisdec: Error on bark_map_size equal to 0. 
The value is used to calculate output LSP curve and a division by zero
