Description (last modified by )
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.
I believe ffmpeg can encode DPLII, but not decode it. 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

I would be very interested in seeing this feature too, perhaps with options to decode to 4, 5, or 5.1 channels.
