Opus mp4 surround files cannot be played in VLC

Hi,

Opus multichannel mp4 files cannot be played in vlc. But the same files work fine in mkv container.

Stereo files show no problem in both mp4 and mkv.

It continues as of today in both 4.x and 3.x final nightly versions of VLC.

I am attaching some screenshots and video files I tested.

I tried to open an issue on Gitlab, but it seems to be quite difficult to open an account. If I could, I would have opened the error as an issue there.

Surround MKV: Surround MKV

Surround MP4: Surround MP4

Test Files and bug images: GoogleDrive
