Haha. It's not that complicated. It's just AAC->decode in ffdshow to format that AC3Filter understands->AC3Filter transcodes to a 6-channel Dolby AC3 stream->receiver sees it as a DVD-spec AC3 stream. My receiver wouldn't know what a DDLive! stream is.
I suppose it's more complicated for me since I don't really know how the information is passed and what controls it to begin with.
I have ffdshow set for all 16 and 32-bit outputs (AC3 output does not work for me). For my external players, it seems as though whatever ffdshow is outputting, AC3Filter is able to grab it instead of my default DirectSound device. I don't know why (lack of know-how here, I'm sure). AC3Filter configuration is set to decode all formats (in 32-bit Float, which is enabled in ffdshow as well), except AAC which is not supported. When I use MP's internal player, it goes straight from ffdshow to the DS device. Are you saying that MP controls the way these files are graphed? If that's the case, then I understand and it's just ignorance on how the lower-level of things play out on my part. I was just expecting for AC3Filter to grab ffdshow's output regardless of the player.
Thanks, it's starting to clear up for me
