Note the presence of DRC formats on TVHTML5 clients #6
Description
TVHTML5 (and formats derived from it, i.e. TVHTML5_VR, TVHTML5_SIMPLY TVHTML5_SIMPLY_EMBEDDED_PLAYER, etc.) contain duplicate audio itags with isDrc/drc=1 on some videos (e.g. xAaxZwAKgTI, Tq92D6wQ1mg, and some other "non-song" videos?)
credits to @selfisekai for also independently finding this out, and specifically how it affects TVHTML5 and related clients
