Function Documentation

◆ avutil_version()

unsigned avutil_version ( void  )

Return the LIBAVUTIL_VERSION_INT constant.

Definition at line 38 of file utils.c.

◆ av_version_info()

const char* av_version_info ( void  )

Return an informative version string.

This usually is the actual release version number or a git commit description. This string has no fixed format and can change any time. It should never be parsed by code.

◆ avutil_configuration()

const char* avutil_configuration ( void  )

Return the libavutil build-time configuration.

Definition at line 60 of file utils.c.

◆ avutil_license()

const char* avutil_license ( void  )

Return the libavutil license.
