           Summary: wavenc: bogus header generated
    Classification: Platform
           Product: GStreamer
           Version: git
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: gst-plugins-good
        AssignedTo: gstreamer-bugs at lists.freedesktop.org
        ReportedBy: phil at base-art.net

Before commit db29522a430e44450415ca3676abd1b77ee923d9 the encoder used to
generate a WAVE header with a bogus size and on EOS rewrite it appropriately
(IIUC).

After that commit the wave.data.len attribute value is zero in
gst_wavenc_create_header_buf() instead of... 0x7FFF0000 in the previous state
of the element.

That seems to have bad side effects on the webkit WebAudio playback pipeline.
The wavenc element used there errors out. I can't yet reproduce that issue
outside of WebKit though... But I thought I'd open a bug anyway, even if it
ends up closed INVALID :)
