* 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. Bultje <rsbultje@gmail.com> Signed-off-by: Ganesh Ajjanagadde <gajjanag@gmail.com>
* 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The new syntax is preferred since it allows backward syntax compatibility with libswr when switching to the new option handling code with AV_OPT_TYPE_CHANNEL_LAYOUT. With the new parser the string: 1234 is interpreted as a channel layout mask, rather than as a number of channels, and thus it's compatible with the current way to set a channel layout as an integer (e.g. for the icl and ocl options) making use of integer option values. ff_get_channel_layout() with compat=0 will be used in the AV_OPT_TYPE_CHANNEL handler code. The user is encouraged to switch to the new forward compatible syntax, which requires to put a trailing "c" when specifying a layout as a number of channels.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add one copy of the function into each of the libraries, similarly to what we do for log2_tab. When using static libs, only one copy of the file_open.o object file gets included, while when using shared libraries, each of them get a copy of its own. This fixes DLL builds with a statically linked C runtime, where each DLL effectively has got its own instance of the C runtime, where file descriptors can't be shared across runtimes. On systems not using msvcrt, the function is not duplicated. Signed-off-by: Martin Storsjö <martin@martin.st>
