aacsbr: Turnoff in the event of over read. Aliased compressed AAC bytes are almost certainly not meaningful SBR data. In the wild this causes harsh artifacts switching HE-AAC streams that don't have SBR headers aligned with segment boundaries. Turning off SBR falls back to a default set of upsampling parameters that can function as a sort of error concealment. This is consistent with how the decoder handles other sorts of errors.
