Expected Behavior

The video should be playing like avPlayer, ExoPlayer or MediaPlayer in windows

Actual Behavior

It will report demuxer errors like this. The reason is the file-exts in this hls do not match the their content. So in order to play, maybe we have to tell Mpv to ignore file-exts and content-types returned by http server. And force it using content sampling to detect file types.
