    initial v2  
    1 I believe ffmpeg can encode DPLII, but not decode it. There are ''a lot'' of old matrix'd movie soundtracks that have never been released in proper multichannel format, and modern AVRs don't support this technology. It would therefore be highly beneficial if ffmpeg could decode them, to ensure they remain playable forever.

    3 I don't know much about coding, but I found this thread on DPLII, which may be helpful for implementing the decoder: https://stackoverflow.com/questions/23713626/correctly-implementing-dolby-pro-logic-ii/23713627
