Clock sync / CORS issue with Live-Clear DASH stream #16

Closed joeyparrish closed 2 years ago

joeyparrish commented 4 years ago

The Live-Clear DASH stream below has a CORS issue:

https://akamai-axtest.akamaized.net/routes/lapd-v1-acceptance/www_c4/Manifest.mpd

It contains UTCTiming reference to Manifest.mpd, but the necessary date header is inaccessible cross-origin, so a web-based player is unable to use this for clock sync.

  <UTCTiming schemeIdUri="urn:mpeg:dash:utc:http-head:2014" value="Manifest.mpd" />

The server is currently returning the header: Access-Control-Allow-Headers: origin,range,hdntl,hdnts. This should include date as well.

I suspect this is a side-effect if #17 since I do see the header in the configuration file but it is indeed not being emitted. Presumably because the stream is down. Will take another look when the stream is back up.

Thanks for reporting!

Looks like my theory was wrong and this is indeed a defect - the stream is back up and the required header does not have the right value. We will adjust the settings shortly to correct this.

The CDN configuration has been updated to correct the headers. The date header is now part of Access-Control-Expose-Headers. Please feel free to close the issue if it looks good from your end.
