[FFmpeg-devel] ffvorbis, inverted output

[Siarhei Siamashka]

Hi,

I tried to do PSNR comparison of libvorbis/ffvorbis/tremor and noticed that
output from ffvorbis is actually inverted (ex. output 0xFFFF in libvorbis
corresponds to 0x0001 in ffvorbis and so on) when compared to the output 
from the other decoders.

Should this be fixed? If yes, what would be the right solution?
Probably just the sign of values in tables in 'vorbis_data.c' could 
be changed.
