stdin: parse error before `r?f?rence': French not supported

You need to add -lavutil to the link command.

Another thing: you shouldn't use -lpthread.  You should compile and
link all code that uses pthreads with the -pthread flag to gcc, which
will then do whatever is needed.  For instance, on some platforms it
might link with a different C library to get reentrant versions of
functions that otherwise would be non-reentrant.
