@paramin graph the filter graph where to link the parsed graph context
@paramin filters string to be parsed
@paramout inputs a linked list of all free (unlinked) inputs of the
parsed graph will be returned here. It is to be freed
by the caller using avfilter_inout_free().
@paramout outputs a linked list of all free (unlinked) outputs of the
parsed graph will be returned here. It is to be freed by the
caller using avfilter_inout_free().
@return zero on success, a negative AVERROR code on error
@note This function returns the inputs and outputs that are left
unlinked after parsing the graph and the caller then deals with
them.
@note This function makes no reference whatsoever to already
existing parts of the graph and the inputs parameter will on return
contain inputs of the newly parsed part of the graph. Analogously
the outputs parameter will contain outputs of the newly created
filters.
Add a graph described by a string to a graph.
