           Summary: [GStreamer][1.4] Caps negotiation failure in playback
                    pipeline
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Platform
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: pnormand at igalia.com


** (WebKitWebProcess:14901): WARNING **: Error: 11, Filter caps do not completely specify the output format. Debug output: gstcapsfilter.c(356): gst_capsfilter_prepare_buf (): /GstPipeline:play/WebKitWebAudioSrc:webkitwebaudiosrc0/GstCapsFilter:capsfilter0:
Output caps are unfixed: EMPTY


The webkitwebaudiosrc bin uses interleave with this chain upfront for each mono channel: queue ! capsfilter ! audioconvert ! i.sink but audioconvert only handles interleaved buffers so the capsfilter has to use interleaved layout as well. Right now it's using non-interleaved and it somehow works fine when webkitgtk is built against 1.2.x but not in 1.4.0.

So let's fix this once for all, using interleaved works fine in 1.2.x and 1.4.x.
