It seems like there are some conflict happening when you try to add sample_convert(..). I haven't found out specifically what causes the conflict, but can look into it if you don't figure it out. I have attached an example where I have modified your project by commenting out the code not needed for sample conversion

I am currently looking into your case, and will try to give you an answer by today or tomorrow
