@param graph the filter graph where to link the parsed graph context
@param filters string to be parsed
@param inputs pointer to a linked list to the inputs of the graph, may be NULL.
If non-NULL, *inputs is updated to contain the list of open inputs
after the parsing, should be freed with avfilter_inout_free().
@param outputs pointer to a linked list to the outputs of the graph, may be NULL.
If non-NULL, *outputs is updated to contain the list of open outputs
after the parsing, should be freed with avfilter_inout_free().
@return non negative on success, a negative AVERROR code on error
@deprecated Use avfilter_graph_parse_ptr() instead.
