* Revert "lavu/atomic: add support for the new memory model aware gcc built-ins"James Almer2017-03-08
| | | | | | | | | | | This reverts commit faa9d2982969c999ab0e443a226eff116f7f8e4b. This change became superfluous when support for C11 atomics was introduced. Reverting it will make the removal of this implementation in an upcoming merge conflict free. Reviewed-by: wm4 <nfxjfg@googlemail.com> Signed-off-by: James Almer <jamrial@gmail.com>

* opus: add a native Opus encoderRostislav Pehlivanov2017-02-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This marks the first time anyone has written an Opus encoder without using any libopus code. The aim of the encoder is to prove how far the format can go by writing the craziest encoder for it. Right now the encoder's basic, it only supports CBR encoding, however internally every single feature the CELT layer has is implemented (except the pitch pre-filter which needs to work well with the rest of whatever gets implemented). Psychoacoustic and rate control systems are under development. The encoder takes in frames of 120 samples and depending on the value of opus_delay the plan is to use the extra buffered frames as lookahead. Right now the encoder will pick the nearest largest legal frame size and won't use the lookahead, but that'll change once there's a psychoacoustic system. Even though its a pretty basic encoder its already outperforming any other native encoder FFmpeg has by a huge amount. The PVQ search algorithm is faster and more accurate than libopus's algorithm so the encoder's performance is close to that of libopus at zero complexity (libopus has more SIMD). The algorithm might be ported to libopus or other codecs using PVQ in the future. The encoder still has a few minor bugs, like desyncs at ultra low bitrates (below 9kbps with 20ms frames).

* configure: use dashes instead of slashes in lib.exe invocationHendrik Leppkes2017-02-06
| | | | | This avoids issues with wrong parameter translation by msys on some systems, and the Windows SDK tools accept both forms equally.
* configure: instruct MSVC 2015 to properly process UTF-8 string literalsHendrik Leppkes2017-02-04
| | | | | | | | | | | Without the /UTF-8 switch, the MSVC compiler treats all files as in the system codepage, instead of in UTF-8, which causes UTF-8 string literals to be interpreted wrong. This switch was only introduced in VS2015 Update 2, and any earlier versions do not have an equivalent solution. Fixes fate-sub-scc on MSVC 2015+
* configure: add nologo switch to invocation of lib.exeHendrik Leppkes2017-02-04
| | | | | This suppresses the startup banner, which is consistent with all other calls to the Windows SDK binaries.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | -pie was added to C flags for ThreadSanitizer in commit 19f251a2882a8d0779b432e63bf282e4d9c443bb. Under clang 3.8.0, the -pie flag causes a compiler warning and a linker error when running configure --toolchain=clang-tsan.
