#define NULL_IF_CONFIG_SMALL

)

x

Return NULL if CONFIG_SMALL is true, otherwise the argument without modification.

Used to disable the definition of strings (for example AVCodec long_names).

#define ONLY_IF_THREADS_ENABLED

x

NULL

Define a function with only the non-default version specified.

On systems with ELF shared libraries, all symbols exported from FFmpeg libraries are tagged with the name and major version of the library to which they belong. If a function is moved from one library to another, a wrapper must be retained in the original location to preserve binary compatibility.

Functions defined with this macro will never be used to resolve symbols by the build-time linker.

Parameters

type	return type of function
name	name of function
args	argument list of function
ver	version tag to assign function Return NULL if a threading library has not been enabled. Used to disable threading functions in AVCodec definitions when not needed.

static av_always_inline av_const int64_t ff_rint64_clip ( double  a, int64_t  amin, int64_t  amax  )

static

Clip and convert a double value into the long long amin-amax range.

This function is needed because conversion of floating point to integers when it does not fit in the integer's representation does not necessarily saturate correctly (usually converted to a cvttsd2si on x86) which saturates numbers

INT64_MAX to INT64_MIN. The standard marks such conversions as undefined

behavior, allowing this sort of mathematically bogus conversions. This provides a safe alternative that is slower obviously but assures safety and better mathematical behavior.

Parameters

a	value to clip
amin	minimum value of the clip range
amax	maximum value of the clip range

Returns

clipped value

Definition at line 274 of file internal.h.

static av_always_inline double ff_exp10 ( double  x )

static

Compute 10^x for floating point values.

Note: this function is by no means "correctly rounded", and is meant as a fast, reasonably accurate approximation. For instance, maximum relative error for the double precision variant is ~ 1e-13 for very small and very large values. This is ~2x faster than GNU libm's approach, which is still off by 2ulp on some inputs.

Parameters

x

exponent

Returns

10^x
