#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.

ver | version tag to assign function Returns NULL if a threading library has not been enabled. Used to disable threading functions in AVCodec definitions when not needed. |
