HD Audio Flagging

Uploaded!

Link removed (Jezz_X)

The TrueHD and DD+ files have 2 audio streams each, 1 being the standard Ddolby core and the second being the HD audio. The normal Dolby core is recognized as ac3 by XBMC and displays a standard Dolby Digital flag in Confluence. The DTSMA only has the one audio stream, and is bitstreamed as normal DTS. I believe if you enable HD audio (LPCM) then XBMC will send the uncompressed (DTSMA) audio to the receiver instead of the DTS core.

Let me know if you need further info on this, I've been doing quite a bit of research into retaining quality from my original sources.

I did a quick check on my laptop with your 300 video. It was showing "truehd" as the codec on the video info panel. I tried adding truehd.png to my audio codec folder, but it still showed dolby digital.

I then tried substring(listitem.audiocodec,truehd) just to see if I could get it to show and it didn't either.

Not sure where to go from there. I am sure Jezz has WAY more knowledge on the codec side of things.

thanks got em and removed the links kind a little on the grey area of legal content better safe than sorry

Right your going to have to help me out here I downloaded 3 of them (didn't bother with both TrueHD ones) and the only thing not showing up was the vc1 logo which I will fix

Bare in mind I am using the latest svn (I don't recommend for you) and I got the following

300.HDDVD.TrueHD.Sample.m2ts showed the Dolby Digital Logo for 1 audio stream and the Dolby TrueHD logo for the other


TransformersRevengeoftheFallen.Bluray.DTSMA.Sample.m2ts showed the DTS logo and 5.1 because thats what it is and is the only channel XBMC found and the "o" codec info showed nothing special for it

KingKong.HDDVD.DD+.Sample.m2ts just shows the Dolby Digital Logo whats so + about it ? its just ac3 5.1 for both channels

Ok figured out the difference in this one and what I was doing wrong
will be fixed in the svn soon but again I don't recommend you use the svn version current it has many errors.

Thanks man!! Awesome! You even fixed the VC1 issue! Can't wait for the next stable release

As for the Transformers clip, that's because at the moment XBMC ignores the Master Audio (HD) and only displays the DTS core. That's why I was suggesting using the file-names. But hey this works for now.
