In version 19.07 I could see audio sample rates for Ogg files with VP9 video. Now with 19.09 I cannot see that information anymore from Ogg files and VP9 Video.
Missing sample rate: (was 48khz previous versions) We have scripts expecting the old behavior...

This is where it fails, seems to be CentOS builds...

MediaInfo Command line,
MediaInfoLib - v19.09
[centos@ip-10-9-38-54 ~]$ uname -a

Can reproduce on MacOS brew 19.09 upgrade too.
Wonder if this change broke the SampleRate setting for Ogg...

I confirmed reverting that commit fixes the issue.
