            Bug ID: 142577
           Summary: [CMake][GStreamer] Building EFL or GTK with
                    ENABLE_VIDEO and without ENABLE_WEB_AUDIO is broken.
    Classification: Unclassified
           Product: WebKit
           Version: 528+ (Nightly build)
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebKit Gtk

Building EFL or GTK with -DENABLE_WEB_AUDIO=OFF is broken (ENABLE_VIDEO is by default on) because the linker needs the flag -lgstaudio-1.0 due to the included functions of gst_stream_volume_get_volume/gst_stream_volume_set_volume/gst_stream_volume_get_type on MediaPlayerPrivateGStreamerBase.cpp when ENABLE_VIDEO is active, and this flag is only used when WEB_AUDIO is also enabled (the default).

This is the error:

$ Tools/Scripts/build-webkit --gtk --release --cmakeargs='-DENABLE_WEB_AUDIO=OFF'

The commit that added that functions to MediaPlayerPrivateGStreamerBase.cpp is r142005 <http://trac.webkit.org/r142005>.
