M2TS remux of original BD only video and TrueHD with AC3 core... not working to output the AC3 core... (yes i need a new receiver but until then...)
trying to playback via MPCHC, tried ffdshow, tried LAV splitter, decoder ... no go
tried to do the graphstudio file -- lav spitter -- lav audio decoder -- output ... no go
firstly ...the LAV splitter was actually not loading ! aka it didnt show the separate tracks truehd, core
and then ... LAV audio would not load (mpchc set as ffdshow blocked and lav audio as preferred) ... so i set ffdshow also preferred ... and uhm ... LAV audio loads ... zomg :X
Only Blu-ray TrueHD files have the embedded AC3 track (so a MKV with TrueHD would not, it may however contain a completely separate track if it was created that way), and as far as i know, only LAV Splitter can properly split it and offer it as a separate stream, Haali cannot.
In my experience, its present on all TrueHD Blu-ray discs, but i cannot guarantee that.
nifty thanks for the info guys. strange thing was that I was actually starting to look around for a solution to this last night. most of my bluray discs have dts-ma, so thats easy to deal with when i make an mkv. this explains why I get 5.1 DD when i play a bluray disc but not an mkv.
for my hd-dvds and small number of bluray discs with truehd in the old days I just converted DD+ and truehd to ac3. When I came to my senses and realized that sooner or later I'd have a new receiver capable of hd audio I started putting both in the mkv file. I guess I will do that until I make a purchase.
so if I were to make m2ts files instead of mkv files, with only a video track and a truehd track, would that work to allow me to output DD? Or would I need to keep something else in there too?
I don't know if any of the commonly used TS muxers can write such a blu-ray compatible track, but if they can, it would work.
On the other hand, i believe MakeMKV can at least split the TrueHD track and the AC3 track, so that you get a MKV with both audio tracks. This would be cleaner and doesn't use any more space either, because all it does is split the track, not add any data.
