Christophe GISQUET	7e1ce6a6ac	dsputil: remove shift parameter from scalarproduct_int16 There is only one caller, which does not need the shifting. Other use cases are situations where different roundings would be needed. The x86 and neon versions are modified accordingly. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago
Ronald S. Bultje	c23acbaed4	Don't use ff_cropTbl[] for IDCT. Results of IDCT can by far outreach the range of ff_cropTbl[], leading to overreads and potentially crashes. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	13 years ago

Diego Biurrun	0144fe6995	Remove Sun medialib glue code. It is obscure, most likely unused and not bit-exact compared to libavcodec due to a different IDCT transform algorithm.	13 years ago
Justin Ruggles	6f1a5e8d6b	dsputil: remove debug message in dsputil_init(). AVCodecContext.bits_per_raw_sample is used for audio too, and values other than 8, 9, and 10 are valid.	13 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
Mans Rullgard	874f1a901d	dsputil: template get_pixels() for different bit depths Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Mans Rullgard	5cc2600964	dsputil: create 16/32-bit dctcoef versions of some functions High bitdepth H.264 needs 32-bit transform coefficients, whereas dnxhd does not. This creates a conflict with the templated functions operating on DCTELEM data. This patch adds a field allowing the caller to choose the element size in dsputil_init() and adds the required functions. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago

Mans Rullgard	7b4ee3a21d	Remove h264_lowres_idct_put/add functions Use of these has been broken ever since the h264 idct was changed to always use transposed inputs. Furthermore, they were only ever used if some other non-default idct was requested. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Mans Rullgard	29b42c66f7	dsputil: fix ff_check_alignment() The change to LOCAL_ALIGNED means the declared object must be an array and the subsequent test should not use the & operator. Noticed by Uoti Urpala. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Diego Biurrun	e463f0e979	dsputil: restore mistakenly removed hunk of disabled code This particular part serves to document the optimized code variant.	14 years ago

Justin Ruggles	6054cd25b4	ac3enc: add int32_t array clipping function to DSPUtil, including x86 versions.	14 years ago
Oskar Arvidsson	19a0729b4c	Adds 8-, 9- and 10-bit versions of some of the functions used by the h264 decoder. This patch lets e.g. dsputil_init chose dsp functions with respect to the bit depth to decode. The naming scheme of bit depth dependent functions is <base name>_<bit depth>[_<prefix>] (i.e. the old clear_blocks_c is now named clear_blocks_8_c). Note: Some of the functions for high bit depth is not dependent on the bit depth, but only on the pixel size. This leaves some room for optimizing binary size. Preparatory patch for high bit depth h264 decoding support. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	14 years ago
Oskar Arvidsson	325eefa2ca	Move some functions in dsputil.c into a new file dsputil_template.c. The functions moved are used when decoding h264. Preparatory patch for high bit depth h264 decoding support. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	14 years ago

Diego Biurrun	6001dad6e2	Replace more FFmpeg references by Libav.	14 years ago
Alex Converse	187a537904	Convert some undefined 1<<31 shifts into 1U<<31. According to ISO 9899:1999 S 6.5.7/4: The result of E1 << E2 is E1 left-shifted E2 bit positions; vacated bits are filled with zeros. If E1 has an unsigned type, the value of the result is E1× 2^E2, reduced modulo one more than the maximum value representable in the result type. If E1 has a signed type and nonnegative value, and E1× 2^E2 is representable in the result type, then that is the resulting value; otherwise, the behavior is undefined.	14 years ago

Mans Rullgard	381d37fda9	dsputil: add bswap16_buf() There are several places where a buffer is byte-swapped in 16-bit units. This allows them to share code which can be optimised for various architectures. Signed-off-by: Mans Rullgard <mans@mansr.com>	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.
