* | avutil/log: added av_log_format_line2 which returns buffer lengthAndreas Weis2016-04-27
| | | | | | | | | | | | | | | | | | The new function behaves the same as av_log_format_line, but also forwards the return value from the underlying snprintf call. This will allow callers to accurately determine the size requirements for the line buffer.

* | pgssubdec: fix subpicture output colorspace and rangeJan Ekström2016-04-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Functionality used before didn't widen the values from limited to full range. Additionally, now the decoder uses BT.709 where it should be used according to the video resolution. Default for not yet set colorimetry is BT.709 due to most observed HDMV content being HD. BT.709 coefficients were gathered from the first two parts of BT.709 to BT.2020 conversion guide in ARIB STD-B62 (Pt. 1, Chapter 6.2.2). They were additionally confirmed by manually calculating values. Fixes #4637

* | x86inc: Enable AVX emulation in additional casesAnton Mitrofanov2016-04-20
| | | | | | | | | | Allows emulation to work when dst is equal to src2 as long as the instruction is commutative, e.g. `addps m0, m1, m0`.
* | x86inc: Improve handling of %ifid with multi-token parametersAnton Mitrofanov2016-04-20
| | | | | | | | | | | | The yasm/nasm preprocessor only checks the first token, which means that parameters such as `dword [rax]` are treated as identifiers, which is generally not what we want.

* | x86inc: Fix AVX emulation of scalar float instructionsHenrik Gramner2016-04-20
| | | | | | | | | | Those instructions are not commutative since they only change the first element in the vector and leave the rest unmodified.

| | | | | | | | | | | | | | | | | | | | All tests were in the main method which produces a long main. Now, each test is in his own method. I think this produces a more clear code and follows more with the main priority of FFmpeg "simplicity and small code size" Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>
* | 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.
