* 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.
* swscale: fix YUV420P 9/10bit support.Ronald S. Bultje2011-05-11
| | | | | | | Fix handling of input if not in native endianness, and add support for 9/10-bit output. This allows us to force endianness of YUV420P 9/10bit in the H264/10bit fate tests, which should fix them on big-endian systems.

* Remove unused softfloat implementation.Diego Biurrun2011-05-11
| | | | | | The softfloat functionality is unused, not installed and incomplete. On platforms without floating point units, the compiler provides a softfloat implementation so there is no point in carrying this code around locally.
* AVOptions: make default_val a union, as proposed in AVOption2.Anton Khirnov2011-05-10
| | | | This breaks API and ABI.
* Add pixel formats for 9- and 10-bit yuv420p.Oskar Arvidsson2011-05-10
| | | | | | | | Also add support for these formats in libswscale. Needed for high bit depth h264 decoding. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>

* lavc: deprecate FF_*_TYPE macros in favor of AV_PICTURE_TYPE_* enumsStefano Sabatini2011-04-26
| | | | | | | | | | | | Also deprecate av_get_pict_type_char() in favor of av_get_picture_type_char(). The new enum and av_get_picture_type_char() are defined in libavutil. This allows the use in libavfilter without the need to link against libavcodec. Signed-off-by: Stefano Sabatini <stefano.sabatini-lala@poste.it> Signed-off-by: Anton Khirnov <anton@khirnov.net>
* bswap: use native types for av_bwap16().Jason Garrett-Glaser2011-04-22
| | | | | | | | | | This prevents a call to bytestream_get_be16() using a movzwl both before and after the ror instruction, which is obviously inefficient. Arm uses the same trick also. Sintel decoding goes from (avg+SD) 9.856 +/- 0.003 to 9.797 +/- 0.003 sec. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>

* error: change AVERROR_EOF valueAnton Khirnov2011-04-21
| | | | | | | | | | The current value is masking the POSIX error code EPIPE, which has a different semantics. This breaks API. Signed-off-by: Stefano Sabatini <stefano.sabatini-lala@poste.it> Signed-off-by: Anton Khirnov <anton@khirnov.net>
* error: remove AVERROR_NUMEXPECTEDStefano Sabatini2011-04-21
| | | | | | | | | | | AVERROR_NUMEXPECTED is used only in the image muxer and demuxer, and has a too much specific meaning, which is better explained through a log message. Thus it can be replaced by AVERROR(EINVAL). This breaks API. Signed-off-by: Stefano Sabatini <stefano.sabatini-lala@poste.it> Signed-off-by: Anton Khirnov <anton@khirnov.net>
* error: add error code AVERROR_OPTION_NOT_FOUND, and use it in opt.cStefano Sabatini2011-04-21
| | | | | | | | The new error code is better than AVERROR(ENOENT), which has a completely different semantics ("No such file or directory"). Signed-off-by: Stefano Sabatini <stefano.sabatini-lala@poste.it> Signed-off-by: Anton Khirnov <anton@khirnov.net>

* Add a CPU flag for the Atom processor.Justin Ruggles2011-03-22
| | | | | | | The Atom has SSSE3 support, which is useful in many cases, but sometimes the SSSE3 version is slower than the SSE2 equivalent on the Atom, but is generally faster on other processors supporting SSSE3. This flag allows for selectively disabling certain SSSE3 functions on the Atom.

* x86: use raw opcode for xgetbv instructionMans Rullgard2011-02-20
| | | | | | | | | | This allows the CPU detection to work with assemblers not supporting the xgetbv mnemonic. These include clang and some BSD versions. All AVX code will be written for yasm, where the main assembler is not involved. Signed-off-by: Mans Rullgard <mans@mansr.com>

* Force inlining of avutil common routinesJason Garrett-Glaser2011-02-17
| | | | | | On some versions of gcc, these weren't always getting inlined due to hitting the inline cap limit in some files. This is generally bad, as most of these functions are smaller inlined than not.

* 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.
