How to resolve the error "we can't play the audio for xxxx video. It's encoded in opus format"?
When playing downloaded YouTube videos (*.mp4) in Windows media player, you may encounter the following error:
"We can't play the audio for xxxx video. It's encoded in opus format, which isn't supported."
This error occurs because Windows media player does not support all audio and video encoding formats. In this case, the video's audio track is encoded using the Opus codec, which Windows media player may not be able to decode. To play the mp4 video without any issues, try opening it in VLC media player, which supports a wide range of audio and video codecs, including opus. VLC can play most media files without requiring additional codec installations.
