* dct: build dct32 as separate object filesMans Rullgard2011-05-17
| | | | | | | This builds the float and fixed-point versions of dct32 separately instead of #including the file in dct.c and mpegaudiodec.c. Signed-off-by: Mans Rullgard <mans@mansr.com>

* mpegaudio: remove OUT_MIN/MAX macrosMans Rullgard2011-05-16
| | | | | | | | These macros are no longer needed after the s32 output was removed. Change the relevant code to use av_clip_int16() instead of using explicit limits. Signed-off-by: Mans Rullgard <mans@mansr.com>

* dct: bypass table allocation for DCT_II of size 32Mans Rullgard2011-05-16
| | | | | | | | The size-32 DCT_II has a special implementation which doesn't use the normal tables. Skipping allocation of these in this case saves some memory. Signed-off-by: Mans Rullgard <mans@mansr.com>
* h264dsp_mmx: Add #ifdefs around some mmxext functions on x86_64.Gil Pedersen2011-05-16

* tiff: add support for SamplesPerPixel tag in tiff_decode_tag()Stefano Sabatini2011-05-12
| | | | | | | | | | | | | Format detection and internal frame initialization is moved to a separate init_image() function, which is called when all the tags have been read, and so both BitsPerSample and SamplesPerPixel information has been collected. This fixes decoding of the file 11.tiff from roundup issue #1925. Based on a patch by Kostya Shishkov <kostya.shishkov@gmail.com>. Signed-off-by: Diego Biurrun <diego@biurrun.de>
* tiff: Prefer enum TiffCompr over int for TiffContext.compr.Stefano Sabatini2011-05-12

* Replace int_fast integer types with their sized standard posix counterparts.Diego Biurrun2011-05-12
| | | | | The _fast integer types provide no realworld benefits, but may introduce portability issues and are just plain ugly.
* jfdct: Replace sized int_fast integer types with plain int/unsigned.Diego Biurrun2011-05-12
| | | | | | int/unsigned is the natural memory access type for CPUs, using sized types for temporary variables, counters and similar just increases code size and can possibly cause a slowdown.
* configure: Do not unconditionally add -D_POSIX_C_SOURCE to CPPFLAGS.Diego Biurrun2011-05-12
| | | | | | | | | | | | | | | | Adding _POSIX_C_SOURCE to CPPFLAGS globally produces all sorts of problems since it causes certain system functions to be hidden on some (BSD) systems. The solution is to only add the flag on systems that really require it, i.e. glibc-based ones. This change makes BSD systems compile out-of-the-box without the need for adding specific flags manually. It also allows dropping a number of flags set manually on a file-per-file basis, but were only present to work around breakage introduced by the presence of _POSIX_C_SOURCE. Also add _XOPEN_SOURCE to CPPFLAGS for glibc systems. We use XSI extensions in several places already, so it is preferable to define it globally instead of littering source files with individual #defines only needed for glibc.

* aac: workaround for compilation on cygwinReinhard Tartler2011-05-11
| | | | | | | | | On cygwin, math.h needs to be included before float.h because of a bug in the system headers. Including libavutil/libm.h first works around this issue. Longer discussion of the topic: http://thread.gmane.org/gmane.comp.video.ffmpeg.devel/128582

* 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>
* Add support for higher QP values in h264.Oskar Arvidsson2011-05-10
