| * w32pthreads: fix mingw build on x86 with -msse2 or higherHendrik Leppkes2015-10-16
| | | | | | | | | | | | | | | | When SSE2 or higher compiler optimizations are used, mingw uses the _mm_mfence intrinsic for MemoryBarrier, however it doesn't include the appropriate headers automatically. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>

| * build: add Solaris symbol versioningSean McGovern2015-10-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The versioning facility in the Solaris linker differs from Linux in 3 ways: 1. It does not support globs in linker scripts for symbol versioning -- this is a GNU extension. 2. The linker argument is '-M', instead of '--version-script'. 3. It is picky about line endings. Each symbol or directive must be on a line of it's own. Let's use make_sunver.pl from GCC to generate a version script that works correctly with the Solaris linker. It's function is to correctly expand the globs in the original generated version script. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>

| * w32threads: Use newer thread synchronization functions when targeting VistaMartin Storsjö2014-08-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When explicitly targeting Vista or newer (which only happens if the caller explicitly sets _WIN32_WINNT to a high enough value via the extra cflags option - otherwise configure script sets -D_WIN32_WINNT=0x0502), we already unconditionally link to the ConditionVariable functions, since 4622f11f9. Similarly use the newer -Ex versions of CreateEvent, CreateSemaphore, InitializeCriticalSection and WaitForSingleObject, that all appeared in Vista. When building Windows Store applications, the older versions of these functions aren't available, only the -Ex functions. When doing such a build, the user can set -D_WIN32_WINNT=0x0600 to forcibly use the newer functions instead. Signed-off-by: Martin Storsjö <martin@martin.st>

| | | | | | | | | | | | | | | | | | | | | | | | | | The values of {FLT,DBL}_{MAX,MIN} macros on some systems (older musl libc, some BSD flavours) are not exactly representable, i.e. (double)DBL_MAX == DBL_MAX is false This violates (at least some interpretations of) the C99 standard and breaks code (e.g. in vf_fps) like double f = DBL_MAX; [...] if (f == DBL_MAX) { // f has not been changed yet [....] }

| | | | | | | | | | | | | | | | | | | | | | | | This reduces the call overhead slightly. More noticeably, it restores the earlier (unintended?) feature that condition variable functions work just fine even if w32thread_init() hasn't been called. This was broken as a side effect of 4622f11f9, if explicitly targeting Vista+. This makes w32threading work in VP8 again, if targeting Vista+. Signed-off-by: Martin Storsjö <martin@martin.st>

* | avisynth: Support video input from AviSynth 2.5 properly.Stephen Hutchinson2013-08-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Uses the 2.5 compatibility header included with the variant of FFMS2 that uses AviSynth's C-interface. A copy of this header is now provided in compat/avisynth. avs_get_row_size_p and avs_get_height_p changed between versions 2.5 and 2.6. Since the avisynth_c.h header that avformat uses assumes AviSynth 2.6, it would cause 2.5 to crash if given any kind of real video (the Version() function was known to work, though). AvxSynth was unaffected by this issue because, despite being based on AviSynth 2.5.8 and using 2.5.8's interface version number of 3, it actually uses 2.6's versions of these functions.
