Notes

Support refers to this format's use in the audio element, not other conditions.

For Opera the Linux version may be able to play it when the GStreamer module is up to date and the served mime-type is 'audio/ogg'.

1. Supported only when packaged in a CAF file and on macOS High Sierra/iOS 11 or later.
