vimeo video in shadowbox now fails

[jjon]

Hello Michael et alia,
Here's a js invocation of shadowbox that used to work and now fails.

function sbInteriorVideo(clipId){
    var clipID = clipId

    $("#sb-body, #sb-loading").css({"background-color": "black"});
    $("#sb-loading-inner span").css({"color": "white"});

    Shadowbox.open({
        options: {
            flashVars:{clip_id:clipID, autoplay:'true', fullscreen: 'true'},
            enableKeys: false,
            overlayColor: '#505',
            overlayOpacity: 0.3,
            resizeDuration: 0.5,
            onClose: function(){
                $("#sb-body, #sb-loading").css({"background-color": "white"});
                $("#sb-loading-inner span").css({"color": "#800"});
            }
        },
        player: 'swf',
        width: 853,
        height: 480,
        content: 'http://vimeo.com/moogaloop.swf'
    });
};

Vimeo's familiar video box appears in a shadowbox, but no video stream, and my console reports:
GET https://11-lvl3-hls.vimeocdn.com/1458682415-0da4e690a70c1a438ada4a889dd0e17dfbb749dd/01/3106/0/15530602/29638816.mp4.m3u8 404 (Not Found)

even though I've verified that there is a video at vimeo with that clipID
shadowbox-js.com seems to be down and I'm fumbling around trying to figure out a fix; any clues?
