Decoding AC-3 (Dolby)/DTS?

Open-source implementations of those, ie liba52 has existed for a long time. Does any code or libraries exist for Microchip chips? The requirement is to read an S/PDIF stream and break it into individual 5.2 or 7.2 channels as I2S or S/PDIF.
 
Is this doable?
 
Yes, I know that there are special chips for this, but all I have seen requires Dolby licensing

    Ping? No one?
     
    I guess porting liba52 to a microchip MCU would suffice.

    It would be interesting. I'm curious so I may search for liba52 as i'm not familiar with it.

    My configuration:
    MacBook Pro (Retina, 15-inch, Mid 2015) with MacOS Mojave (10.14.6) and MPLAB X IDE v5.30
     
    Curiosity PIC32MZ EF 1 & 2, PIC24F Curiosity, XPRESS EVAL BOARD (PIC16F18855), SAMA5D3 Xplained and various custom boards.

    I've spent quite a lot of time playing with MP3 and AAC decoding and have never run across a Dolby decoder library, but then again I wasn't looking...
     
    You could try the hydrogenaud.io website. A lot of audio experts there.
