* Adds 8-, 9- and 10-bit versions of some of the functions used by the h264 ↵Oskar Arvidsson2011-05-10
| | | | | | | | | | | | | | | | | 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.

| | | | | | | | 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>

* 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.

* Remove duplicate definitions of fullpel MC functionsMåns Rullgård2010-08-25
| | | | | | | This removes duplicated definitions of 8x8 and 16x16 fullpel MC functions with various names reducing dsputil.o by 8k on x86_64. Originally committed as revision 24933 to svn://svn.ffmpeg.org/ffmpeg/trunk

* 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

* Move H264 dsputil functions into their own structMåns Rullgård2010-03-16
| | | | | | | | | | | This moves the H264-specific functions from DSPContext to the new H264DSPContext. The code is made conditional on CONFIG_H264DSP which is set by the codecs requiring it. The qpel and chroma MC functions are not moved as these are used by non-h264 code. Originally committed as revision 22565 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Separate DWT from snow and dsputilMåns Rullgård2010-03-14
| | | | | | | | This moves the DWT functions from snow.c and dsputil.c to a file of their own. A new struct, DWTContext, holds the function pointers previously part of DSPContext. Originally committed as revision 22522 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Add some required castsMåns Rullgård2010-03-11
| | | | | | | | These casts are correct and safe. The pointers are guaranteed to have proper alignment, and aliasing is not a problem with character types. Originally committed as revision 22446 to svn://svn.ffmpeg.org/ffmpeg/trunk
