           Summary: [iOS] WebM video does not display
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal

WebM video playback on iOS only displays as a black screen. The same videos work fine in Mac Safari. Note that audio playback works fine.

Steps To Reproduce:
1. Play a WebM video. For example: https://www.webmfiles.org/demo-files/ or https://en.wikipedia.org/wiki/File:NORWAY_TRIP_(4K).webm (tap on “Original File”)
2. Video should be displayed but it is not.
