#define NDEBUG

Definition at line 30 of file internal.h.

#define NULL_IF_CONFIG_SMALL (   x)    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).

Definition at line 191 of file internal.h.

Referenced by mpeg12_class().

#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 Libav 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
typereturn type of function
namename of function
argsargument list of function
verversion 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.
