Diego Biurrun	aaf47bcde7	Drop ALT_ prefix from BITSTREAM_READER_LE name. The prefix is a historic remnant that probably meant "alternative". Now that the A32 bitstream reader has been dropped it makes no sense anymore.	13 years ago

Reimar Döffinger	0e29c4f761	Revert bink dequantization hack that is no longer necessary. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>	14 years ago
Anton Khirnov	ec6402b7c5	lavc: use designated initialisers for all codecs. It's more readable and less prone to breakage.	14 years ago
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
Reimar Döffinger	47b71eea09	Bink: clip AC coefficients during dequantization. Fixes artefacts with Neverwinter Nights WOTCLogo.bik (http://drmccoy.de/zeugs/WOTCLogo.bik). Fixes trac ticket #352. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>	14 years ago

Reinhard Tartler	7ffe76e540	Merge libavcore into libavutil Done to keep ABI compatible. Otherwise this is just silly	14 years ago
Reinhard Tartler	737eb5976f	Merge libavcore into libavutil It is pretty hopeless that other considerable projects will adopt libavutil alone in other projects. Projects that need small footprint are better off with more specialized libraries such as gnulib or rather just copy the necessary parts that they need. With this in mind, nobody is helped by having libavutil and libavcore split. In order to ease maintenance inside and around FFmpeg and to reduce confusion where to put common code, avcore's functionality is merged (back) to avutil.

Peter Ross	f20886e464	bink: permute Bink version 'b' quant matrices by inverse scan order This fixes visual glitches in Bink version 'b' files, as the quantization tables were not being permuted. Signed-off-by: Mans Rullgard <mans@mansr.com> (cherry picked from commit `2315392174`)	14 years ago

Vitor Sessak	0a18b64585	Make tables generation insensitive to floating-point implementation Using doubles make the double -> int cast well defined for all the values used, with the exception of when s[i]==1.0, which is special-cased.

Kostya Shishkov	03ec42aa1c	Change some band size calculations in Bink decoder to use width in blocks instead of real width, this fixes decoding of some Bink files with odd width. Originally committed as revision 26364 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
