We really need at least two periods: with only one period we could hit
a buffer underrun after a buffer overrun (a REALLY dumb failure...).
Then we have a favorite buffer size. Then we pick the least number of
periods to reduce wakeups (but at least 2 anyway).

If set_format() fails, the parameters are unrecoverable.
Use test_format() instead.

It is good enough for normal people with only half the CPU usage of
medium quality SinC.

If GCC -ffast-math is not supported, some floating point optimizations
are still possible through more standard means:

"FP_CONTRACT on" is a subset of -funsafe-math-optimizations.

"FENV_ACCESS off" corresponds to -frounding-math.

"CX_LIMITED_RANGE on" corresponds to -fcx-limited-range, but is not
included as VLC does not use complex numbers anywhere yet.

macosx: disable the libsamplerate plugin by default to save 5 to 11 per cent of CPU load on an i5 when playing ordinary stereo audio (AAC, 128kb/s)

the performance impact is even more noticeble on older CPUs of course

Don't assume IV has 32 digits (leading zeroes are not mentioned in the
spec)

Also don't use a temporary buffer to read the key

The check would only reset the output if the sample rate or the
bandwidth changed. For example a switch from 16-bits stereo to
32-bits mono would be undetected. Fortunately, this probably never
happened in practice.

They are mainly for audio_format_t which is also defined there. Many
files included <vlc_aout.h> only for these.

This avoids extraneous libraries when libmodplug is a dynamic library.

pkg-config is unable to autodetect whether a package is linked
statically or not. This helper just moves Libs.private into Libs
manually in case only a static library is built. Most if not all of
contribs are built that way.

Some people actually use it.

macosx: added additional artwork for the single fullscreen button in the detached video output window

derived from previous artwork for other single buttons

macosx: fixed aspect ratio and crop commands by removing a no longer needed hack (close #5921, close #6080)

code needs factorization with the main window

Using str*() on a bytestream is a bad idea.
