Please understand that to the best of my knowledge, 
this simply makes no sense for us, and support is 
therefore very limited.
(People have claimed that every single function of 
FFmpeg is covered by as many "intellectual rights" 
as the Dolby codecs.)

Since this is a regression, I posted a patch 
that you can apply manually until it is

This option has no effect (and often leads to 
misunderstandings), please remove it.

I am very surprised that you fear license issues 
but are using this option...

I don't think this has the effect that you 
believe it has, I suggest you remove it.

For many years, you can use:
--disable-encoder=ac3* --disable-decoder=ac3,eac3
simplifying your configure line

I thought dts has nothing to do with Dolby...
