Mans Rullgard	1b3539d453	dsputil: move a bink-only function to binkdsp Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Kostya Shishkov	2968bedf12	bink: make IDCT take 32-bit input Since IDCT transforming 32-bit input to 8-bit output is unusual and unpractical for most codecs, move Bink IDCT into separate context. Get rid of an additional permutation table while at it since SIMD support for Bink IDCT is unlikely to be implemented in foreseeable future. Quantisation tables also have to change type to signed for proper dequantisation of DCT coefficients. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago

Passing an explicit filename to this command is only necessary if the documentation in the @file block refers to a file different from the one the block resides in.
