Report extended channel count for audio formats with core/extended channels

[Omertron]

Original issue 2398 created by Omertron on 2012-04-05T00:58:08.000Z:

Using YAMJ 2.6.1 on Popcorn Hour C-200 models.

For a format such as DTS-HD Master Audio in MKV files, YAMJ is populating the XML file with most of the metadata referencing the track as a DTS-HD MA track, but is taking the number of channels from the 'core' channels rather than the 'extended' channels.

This means that DTS-HD MA 7.1 tracks are being flagged as 5.1 (which is the DTS core) rather than 7.1, despite being labelled as DTS-HD MA (which implies the extended track).

The relevant output from mediaInfo for a track like this would be:
Format : DTS
Format/Info : Digital Theater Systems
Format profile : MA / Core
Codec ID : A_DTS
Duration : 1h 40mn
Bit rate mode : Variable
Bit rate : 1 924 Kbps / 1 510 Kbps
Channel(s) : 8 channels / 6 channels
Channel positions : Front: L C R, Side: L R, Back: L R, LFE / Front: L C R, Side: L R, LFE
Sampling rate : 48.0 KHz
Bit depth : 24 bits
Compression mode : Lossless / Lossy

The XML currently contains the following:
<audioCodec>DTS-HD (en)</audioCodec>
<codecs>
<audio count="1">
<codec bitrate="1923" channels="6" codecId="A_DTS" codecIdHint="UNKNOWN" format="DTS"
formatProfile="MA / Core"
formatVersion="UNKNOWN"
language="en"
langugageFull="English">DTS-HD</codec>
</audio>
</codecs>
<audioChannels>6</audioChannels>

Since everything in the XML references the full DTS-HD MA track rather than its DTS core, with the exception of the number of channels, I believe that the <channels> entry and also the channel count in the <codec> entry should both return the extended channel count.

I have found the same behaviour with some DTS-HD High Resolution Audio 6.1 tracks as well.

I guess the same would apply to TrueHD but I don't have any files with >5.1 channels to test and see how these behave.

A 6.1 DTS-HD HRA mediaInfo would look like:
Format : DTS
Format/Info : Digital Theater Systems
Format profile : HRA / Core
Codec ID : A_DTS
Duration : 1h 39mn
Bit rate mode : Constant
Bit rate : 1 510 Kbps
Channel(s) : 7 channels / 6 channels
Channel positions : Front: L C R, Side: L R, Back: C, LFE / Front: L C R, Side: L R, LFE
Sampling rate : 48.0 KHz
Bit depth : 24 bits
Compression mode : Lossy
