Ok I just built the echoprint-codegen binary and ran it against a few TV show recordings. It works as expected but I get no match against the song/identify API servers. The other album mp3 songs that came back correctly using ENMFP (codegen.Darwin) are no longer returning results either.
Originally I steered away from echoprint because I was under the impression that I would not be able to match against as many songs as ENMFP but now I see I'm using the same API end points in both scenarios, so is echoprint querying the same data as ENMFP?
