As the title says, the ac3 stream is not always detected when the primary stream is a truehd or an atmos one.

How many discs are affected by this? I am running tests on my library, but can't reproduce this behaviour so far.

nautilus7 commented 6 years ago

Hi, thanks for the reply.

Well, I tested 3 discs that I had in my hard disc and 2 of them had the issue. I will test more and try to find some pattern, so you can reproduce it.

nautilus7 commented 6 years ago

I tried another ~10 discs and none of them has this issue. So I uploaded a sample of the Blade Runner disc that has it, in case that helps. It's the complete bd structure with only a small piece of the main movie m2ts file.

UniqProject commented 6 years ago

Thanks, I could not reproduce it on my discs either. However, with your sample I think I may have fixed this, please try this one: BDInfo_v0.7.3.3b.zip

nautilus7 commented 6 years ago

Yes, actually both of my discs that didn't display the embedded ac3 track work ok now. Thanks for the quick fix!

Awesome!
