What did you do?

I tried to play the video with a duration of over 1h on the Xbox One. In our case, our manifests include SegmentTimeline tag.

What did you expect to happen? The video will start playback.

What actually happened?

Player throws an error when we try to play the video:

Can not load manifest: shaka.util.Error { "severity": 2, "category": 4, "code": 4001, "data": [ "https://example-site.com/master.mpd" ], "handled": false }

Which is DASH_INVALID_XML, 4001, The DASH Manifest contained invalid XML markup.

It works well on v2.5.2 and it does not on v2.5.3. We looked deeper and found that it’s playing fine if we change string utility fromCharCode back to the implementation of what it was in v2.5.2. Also, we found that this issue is only reproducible with Compiled (Release) code, it’s playing fine in the Compiled (Debug) and Uncompiled modes.

I’ll make the arbitrary decision to start assembling the v2.5.9 release on Monday Feb 3. 😃 It isn’t always completed in the same day, but you can expect it some time next week.

Cherry-picked to v2.5.9.
