[Libav-user] Do we need license from Dolby to use ac3, eac-3 decoding in FFmpeg

[drwho]

Is this going in a product that you sell?

If the product or it's advertising has a Dolby Logo or the word Dolby or 
any Dolby trademark....

   --> You will most likely need a license to use the Logo and trademarks.

   --> You will need to pass Dolby certification to meet the 
requirements for the license.  Dolby will probably require you to use 
their decoder.  I've got different responses from them about this over 
the years.
