            Bug ID: 282228
           Summary: [MediaRecorder] Encoding H264 content is broken
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebRTC
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: jean-yves.avenard at apple.com
                CC: youennf at gmail.com

Testing https://jyavenard.github.io/htmltests/tests/MediaRecorder/


Generating a MP4 recording with H264 creates invalid content. 

It appears that the H264 VideoEncoder is generating errors
