I do not see how to access ISRC in the documentation. Inferring from the "link_coverart" sample which is the only LINK library example, and because of this thread pointing out that ISRC is contained in the enriched metadata of LINK, i've made this :
The process seems to be good (there is no error on the option_set) but in the content_retrieve call, there is an error on the gnsdk_link_content_unknown. Problem is there is no matching content in the gnsdk_link_content_type_t enum from include/gnsdk_link.h
Any help or resource would be greatly appreciated.
