Audio Information Not Displaying Properly

My audio bindings aren't displaying the correct details. For example, with the Mediainfo log displaying the following audio details:
The {channels} binding returns 5.1 whereas it is actually 7.1
(The {af} binding does display as 8 ch but I would rather use {channels} to show 7.1)
Also, how can I include Dolby Digital Plus in the renaming (or preferably to show as DD+ )?

Are you using the same version of MediaInfo that FileBot is using internally?
filebot -script fn:sysinfo will tell.
Please copy filebot mediainfo script output, so we can see what FileBot sees:
Code: Select all
filebot -script fn:mediainfo /path/to/file

I am using MediaInfo 19.09. FileBot is using MediaInfo 18.12.
Not sure how to do the script but hopefully the GUI method provides the information needed:
I notice the ChannelPositions/String2 of 3/2/0.1 may be where FileBot is pulling the 5.1 from. What is this information referring to?

ChannelPositions/String2 is used yes
MediaInfo is the problem here.... update it if you can or report the file to MediaInfo
btw: you can test file here:

1.
Indeed,
ChannelPositions/String2 is what is being used here to add up the
{channels} value.
You can try the latest beta, which bundles a more recent libmediainfo, to see if it works better with the latest and greatest:
viewtopic.php?t=1609
Alternatively, you can use
{af} which will give a value of
8ch based on the
Channel(s) field.
2.
I see that
Dolby Digital Plus is available via MediaInfo, so you can access it for Audio Stream #1 like so:
If you wanna tag files with
DD+ if any audio stream matches, then you can do that like so:
Code: Select all
audio.FormatCommercial =~ /Dolby Digital Plus/ ? /DD+/ : null

Unfortunately FileBot 4.9 also is using ChannelPositions/String2 to add up the channels to 5.1.
My logs and the information from
https://mediaarea.net/MediaInfoOnline does not show the ChannelPositions/String2 field at all. Can FileBot ignore ChannelPositions/String2 and pull the information from another field for {channels}?

I made an alternative... using e.g. 'Front: L C R, Side: L R, LFE' instead of '3/2/0.1'
Code: Select all
{ any{ audio.ChannelPositions*.replaceAll(/Front:|Side:|Back:|Wide:|Object Based|,/).findAll()*.replaceAll(/LFE/, '0.1')*.replaceAll(/L|C|R/, '1')*.split().collect{it*.toDouble().sum() }.max() } { audio.Channels*.toDouble().max() } }

Is the information we need available or encoded in some way in another field? If
ChannelPositions contains the information you need then @kim already has a solution for you.

Thanks kim! Your alternative works perfectly! Thanks rednoah for your help as well.

@kim Do you think this approach is better than adding up
ChannelPositions/String2 or are there any pitfalls you can think of that might make it work less well? Because if this approach generally works better, then maybe changing the internal implementation for
{channels} makes sense.

I dont' know how it's generated, but my guess is after looking at this that "ChannelLayout" is the primary (base) for Channel(s), Channel(s)/String, ChannelPositions, ChannelPositions/String2 ?
https://sourceforge.net/p/mediainfo/dis ... /959f2a6b/
You can ask Jerome Martinez how it works:
https://sourceforge.net/u/zenitram/profile/
so maybe this is better ?
Code: Select all
{ any{ audio.ChannelLayout*.replaceAll(/Object Based/)*.split()*.collect{ it.replace(/LFE/, '0.1').replaceFirst(/(\b(?:L|R|C)(?:b+|s+|w+)?\b)/, '1').toDouble() }.findAll()*.sum().max()}{ audio.Channels*.toDouble().max() } }
but then again... WEIRD
Channel(s) 2
Channel(s)/String 2 channels
ChannelPositions Front: L R
ChannelPositions/String2 12/1/0.1
ChannelLayout ? Cb LFE
btw: 2 ch is correct
+
Channel(s) 8
Channel(s)/String 8 channels
Channel(s)_Original Object Based
Channel(s)_Original/String Object Based
ChannelPositions Object Based
ChannelPositions/String2 Object Based
ChannelLayout Object Based

version 2
Code: Select all
{ any{ audio.ChannelLayout*.replaceAll(/Object Based/)*.split()*.collect{ it.replace(/LFE/, '0.1').replaceFirst(/(\b(?:L|R|C)(?:b+|s+|w+)?\b)/, '1').toDouble() }*.sum().collect{ it == null ? audio.findAll{ it.ChannelLayout == /Object Based/ }.Channels*.replace(/8/,'7.1')*.replace(/6/,'5.1')[0] + ' (Objs)' : it }[0] }{ audio.Channels[0].toDouble() } }
e.g. output
7.1 (Objs)
5.1
2.0

e.g. output
7.1 (Objs)
5.1
2.0
This ends up in the any's fallback (audio.Channels[0].toDouble(), result is "8.0") but it should end up being "7.1"

FileBot r6975 will be counting {channels} based on audio.ChannelLayout, but default to {af} is it's all Object Based or plain undefined.

ok then
version 3
just replace the '0' in "def au0 = 0" to change audio channel
Code: Select all
{
def au0 = 0; def ch0 = audio.Channels[au0]?.toInteger();
any{ audio.ChannelLayout*.replaceAll(/Object Based/)*.split()*.collect{ it.replace(/LFE/, '0.1').replaceFirst(/(\b(?:L|R|C)(?:b+|s+|w+)?\b)/, '1').toDouble() }*.sum().collect{ it == null ? audio.findAll{ it.ChannelLayout == /Object Based/ }.Channels*.replace(/8/,'7.1')*.replace(/6/,'5.1')[au0] + ' (Objs)' : it }[au0] }
{audio.Title[au0].match(/\d\.\d/)}
{ ch0 >= 6 ? (ch0 - 1 + 0.1) : ch0.toDouble() }
}
@rednoah
it looks like "audio.Title" often has the channels info
