* bink: make IDCT take 32-bit inputKostya Shishkov2011-07-27
| | | | | | | | | | | 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>

* dsputil: create 16/32-bit dctcoef versions of some functionsMans Rullgard2011-07-21
| | | | | | | | | | 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>

* Remove h264_lowres_idct_put/add functionsMans Rullgard2011-07-20
| | | | | | | | 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>
* dsputil: fix ff_check_alignment()Mans Rullgard2011-07-19
| | | | | | | | | 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>

| | | | | | | | | | | | | | | | | 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>

* Convert some undefined 1<<31 shifts into 1U<<31.Alex Converse2011-04-11
| | | | | | | | | | | 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.

* Merge libavcore into libavutilReinhard Tartler2011-02-15
| | | | | | | | | | | | 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.

* Make ff_inverse stay with libavutil, and optional copy it to libavcodec.Diego Pettenò2010-07-21
| | | | | | | | | | | | | | | | | | | The ff_inverse table is used by FASTDIV macro, defined in libavutil, but up to now the table was defined only in libavcodec. After this change, the main copy of ff_inverse is part of libavutil (just like FASTDIV), but if CONFIG_SMALL is unset, then a different copy is made available to libavcodec, to avoid the performance penalty of using an external look up table. Dynamic linking works, because the libraries are linked with -Bsymbolic, so the local copy of the symbol has priority over the external; static linking works because the table is on a standalone object file in both libraries, so the linker is able to discard one of the two. Tested on Linux/x86-64 and Mac OS X/x86-64. Originally committed as revision 24383 to svn://svn.ffmpeg.org/ffmpeg/trunk
