I noticed that VLC could not display the sound of videos that used AOMedia's AV1 codec, or AOM-AV1 in short. When I tried to play videos in that specific codec, I could only hear the sound of the video. This did not occur in other codecs such as H.264 and H.265. I ran video players in terminal, hoping to catch error messages.

The videos play just fine on VLC on Windows so the videos aren't corrupted. What packages need to be fixed here?
