            Bug ID: 218388
           Summary: Add feature detection support for FLAC in HLS
           Product: WebKit
           Version: Safari 14
          Hardware: Macintosh
                OS: Other
            Status: NEW
          Severity: Critical
          Priority: P2
         Component: Media
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: jeremy.karlsson at tidal.com

With the new support for FLAC in HLS we intend to finally get FLAC support out on Safari at TIDAL. I have however not find a way to feature detetect the capabilities to know if I can play FLAC or not.

FLAC in HLS only works in Safari 14 on Big Sur. But Safari on El Capitan returns the same values when running these methods;


document.createElement('video').canPlayType('audio/mp4; codecs="flac"');
document.createElement('video').canPlayType('application/vnd.apple.mpegurl; codecs="flac"');
window.WebKitMediaKeys.isTypeSupported('com.apple.fps.1_0', 'video/mp4; codec="flac"')';
