Hey guys,
does anybody know anything about TrueHD headers? I've received some information from Pelican (thanks!), but there's still some information missing for my needs. Basically I want to remove the DialNorm information from TrueHD streams. So I need to know where the DialNorm information is stored in the header. Well, probably I could figure that out myself by trial and error. But when I tried to do so, the Sonic TrueHD decoder refused to play the modified stream. So I suspect that there's a CRC somewhere (just like in AC3 and E-AC3). So what I need to know is where the CRC is stored and how I can recalculate it.
So if anybody can help out, I'd be quite thankful!! :)
