[12:10:27 CDT(-0500)] <anastasiac> UIEnhancer stores language preferences as a language code, e.g. "en"
[12:10:42 CDT(-0500)] <anastasiac> the video player stores the language preference as an index into the array of tracks
[12:11:04 CDT(-0500)] <anastasiac> so the transformation function needs to search through the array of tracks for (the first) one that has the specified language code
[12:11:24 CDT(-0500)] <anastasiac> so the question is: how to get the array of tracks to the transformation function?
