            Bug ID: 164585
           Summary: [GStreamer][OWR] bad video rendering in apprtc
    Classification: Unclassified
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Platform
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: pnormand at igalia.com

The apprtc service uses 3 video elements in total, one for local, one for remote and one called preview. During a call only remote and preview are displayed, preview being linked to the same mediastream as local. The consequence is that 2 OWR video renderers of the same source are created. When gst-gl is enabled this isn't a problem but when it is disabled a performance issue appears and the webkit video sink starts dropping frames.

The solution would be to have the video renderer shared between the 2 media players in this scenario.
