Missing value audioChannelConfiguration

Created by: jakubfrydrych

Hi, I am solving a problem where some sources that have multiple audio tracks do not contain the number of audio channels in MediaInfo.audioChannelConfiguration[]. The difference is probably the immersion of an element containing information about the number of channels in the manifest. Alternatively, is there any other place to obtain this information?

The behavior can be reproduced in the dashjs 3.0 demo player for example on these resources. dashjs demo player

Manifest to test missing values https://media.axprod.net/TestVectors/v8-MultiContent/Clear/Manifest.mpd https://media.axprod.net/TestVectors/v7-Clear/Manifest_1080p.mpd

Manifest to test contains values http://rdmedia.bbc.co.uk/dash/ondemand/testcard/1/client_manifest-audio.mpd

player.getCurrentTrackFor('audio'); // audioChannelConfiguration

Thanks for any advice
