Description Cameron Hutchison 2002-09-01 15:03:16 UTC 
Gstreamer is crashing when I am using threads. The bug can be reproduced
with the command:

$ gst-launch sinesrc ! { queue ! fakesink }

The error reported is:

GStreamer-CRITICAL **: file gstdata.c: line 196 (gst_data_unref): assertion
`GST_DATA_REFCOUNT_VALUE (data) > 0' failed

The amount of time it takes to crash is quite variable. If I pipe the
output of the command to "wc -l", I've got these results:
494, 5286, 4763, 4934, 1506, 19520, 2349

This does not crash if you take out the queue and the thread.

NOTE: this is running on a SMP box. I haven't tried it on a UP box.

Assume this is fixed after SMP patch was commited.

[Gtk] Add WK1 API for snapshot retrieval
        https://bugs.webkit.org/show_bug.cgi?id=92261

        Reviewed by NOBODY (OOPS!).

        Added a method to ChromeClientGtk that paints the webview contents
        into a cairo_surface and add the public API to WebKitWebView for
        this.

        * WebCoreSupport/ChromeClientGtk.cpp:
        (WebKit::ChromeClient::paintWebViewInSurface): Paint
        the ChromeClient in a given cairo_surface.
        * WebCoreSupport/ChromeClientGtk.h:
        (ChromeClient): Ditto.
        * webkit/webkitwebview.cpp:
        (webkit_web_view_get_snapshot): New
        method to paint a webview snapshot.
        * webkit/webkitwebview.h: Ditto.
