Description Enrique Ocaña 2017-10-25 11:40:24 PDT
A deadlock may occur when UI thread tries to clear pipeline in AppendPipeline::clearPlayerPrivate() while parser thread tries to change pipeline state to pause holding the stream lock in AppendPipeline::connectDemuxerSrcPadToAppsinkFromAnyThread().

This issue has been fixed downstream in https://github.com/WebPlatformForEmbedded/WPEWebKit/pull/392
