Media flags – Where to get data for Infolabels (broken since 17)

Hello,

I am used to media flags, gathered through Infolabels, especially:
ListItem.AudioChannels
ListItem.AudioCodec
ListItem.VideoCodec
ListItem.VideoResolution

However, from Kodi 17 beyond, those are not correctly displayed, contrary to Kodi 16, where those parameters are visible.

Can anyone help me, where Kodi gather (through what, filename, file command, or whatever) those information? Something definitivelly changed, I need to figure this out, before bump to 17 Smile

Thanks in advance
