|\ | | | | | | | | | | | | * commit '3152058bf1dca318898550efacf0286f4836cae6': libavcodec: Don't use dllexport, only dllimport when building DLLs Merged-by: James Almer <jamrial@gmail.com>
* | Avoid corrupting diagnostic state with _Pragma changes.Dale Curtis2017-11-14
| | | | | | | | | | | | | | | | | | | | | | The macros for ICC and MSVC correctly push and pop the diagnostic state of the compiler when disabling deprecation warnings. The ones for clang/gcc should do the same. Without this, if a blanket deprecation warning is applied to the code base it'll be flipped back on incorrectly with FF_ENABLE_DEPRECATION_WARNINGS.

| * msvc: Properly specify dllexport for data symbols shared across dll boundariesMartin Storsjö2017-08-31
| | | | | | | | | | | | | | | | | | We currently only have exported data symbols within libavcodec, but the concept is easy to extend to other libraries if necessary. The attribute declaration needs to be in a private header though, since we can't use CONFIG_SHARED in public installed headers. Signed-off-by: Martin Storsjö <martin@martin.st>

* | all: move ff_exp10, ff_exp10f, ff_fast_powf to lavu/ffmath.hGanesh Ajjanagadde2016-03-22
| | | | | | | | | | | | | | | | | | | | | | The idea is to use ffmath.h for internal implementations of math functions. Currently, it is used for variants of libm functions, but is by no means limited to such things. Note that this is not exported; use lavu/mathematics for such purposes. Reviewed-by: Ronald S.

* | lavc/aacenc_utils: replace powf(x,y) by expf(logf(x), y)Ganesh Ajjanagadde2016-03-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is ~2x faster for y not an integer on Haswell+GCC, and should generally be faster due to the fact that anyway powf essentially does this under the hood. Made an inline function in lavu/internal.h for this purpose. Note that there are some accuracy differences, that should generally be negligible. In particular, FATE still passes on this platform. Results in ~ 7% speedup in aac encoding with -march=native, Haswell+GCC. before: ffmpeg -i sin.flac -acodec aac -y sin_new.aac 6.05s user 0.06s system 104% cpu 5.821 total after: ffmpeg -i sin.flac -acodec aac -y sin_new.aac 5.67s user 0.03s system 105% cpu 5.416 total This is also faster than an alternative approach that pulls in powf, gets rid of the crufty NaN checks and other special cases, exploits knowledge about the intervals, etc. This of course does not exclude smarter approaches; just suggests that there would need to be significant work on this front of lower utility than searches for hotspots elsewhere.

| * libavutil: move FFALIGN macro from common.h to macros.hJanne Grunau2015-12-14
| | | | | | | | | | | | | | | | | | Include macros.h explicitly in common.h so that external code using FFALIGN does not break. It was already implicitly included through version.h. Include macros.h in lls.h and internal.h for FFALIGN. lls.h was including common.h only for FFALIGN and internal.h was missing the include for FFALIGN. `make checkheaders` did not catch it because it's an internal header.
* | lavu/internal: add ff_exp10Ganesh Ajjanagadde2015-12-25
| | | | | | | | | | | | | | | | | | | | | | | | | | Fast, reasonably accurate 10^x. Alternative of detection of libm exp10 at configure time is not worth the trouble, since it is anyway not POSIX or ISO C, and currently only the GNU libm has it. Furthermore, GNU libm's variant is ~ 2x slower, and is ironically not correctly rounded (2 ulp off) to justify all that slowdown.
