If the user attempts to use AviSynth 2.5, an error message will
now tell them they need to upgrade.

The demuxer doesn't use these functions, so it shouldn't affect
anything. Investigate whether this can be fixed by how headers
are checked in configure.

This avoids annoying warnings about unused functions. The compatibility
wrapper is designed to provide a complete (stub) API, so some functions
being unused by some files is natural and no reason for a warning.

w32threads: Use newer thread synchronization functions when targeting Vista
Merged-by: Michael Niedermayer <michaelni@gmx.at>
|
|
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.

Work around broken floating point limits on some systems.
Merged-by: Michael Niedermayer <michaelni@gmx.at>
|
|
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
[....]
}

w32threads: Don't use function pointers when linking directly to newer APIs
Merged-by: Michael Niedermayer <michaelni@gmx.at>

This reverts commit 4622f11f9c83db8a2e08408c71ff901826ca652c.
The compiler should be able to do the dead code elimination now
without this when the cond_* names point directly to the real
functions instead of to local function pointers.

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+.

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.
