            Bug ID: 190638
           Summary: Safari is not able to adapt between H264 streams with
                    EditList and without EditList
           Product: WebKit
           Version: Safari 12
          Hardware: Macintosh
                OS: macOS 10.13
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Media Elements
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: kqyang at google.com

To re-pro, 

1. Go to https://shaka-player-demo.appspot.com/demo/#asset=https://storage.googleapis.com/wvtest/shaka-packager/historical/v2.2/misc/ClearPackaged/clear_tears.mpd;lang=en-US;build=uncompiled
2. select Load and Begin playback.
3. Tears begins and after a few seconds into playback responds with: Shaka Error MEDIA.VIDEO_ERROR (3,,) with spinner on screen

The problem occurs when player was trying to adapt to a higher resolution.

It is common to see H264 streams with base profile and main profile in the same AdaptationSet. The H264 stream with base profile will not have EditList while it is common for the H264 stream with main profile to contain an EditList.


The same manifest works in other browsers. I don't see it being disallowed in the spec either.
