+ If a codec spec defines dts in a way incompatible to this then the decoder
+ dts shall be considered to be entirely outside the nut spec. In this case

+ purely based on the pts values stored in a nut file.
+ Such nut files MUST NOT contain non standard fields conveying these codec
+ dts as this would break remuxing, spliting, merging and time scaling by
