Bug 117736 – [GStreamer] Potential race condition when getting the video sink caps.

• Component: WebKit Misc.
• Status: RESOLVED FIXED

[Víctor M. Jáquez L.]

There is a potential race condition with the pad setting caps, as the buffer and the caps won't match when renegotiation happens, and might cause a crash.

Ok, just a couple of nitpicks:

> Source/WebCore/platform/graphics/gstreamer/VideoSinkGStreamer.cpp:302
> +static void webkitVideoSinkGetProperty(GObject *object, guint propId, GValue *value, GParamSpec *pspec)

The stars are misplaced, we also prefer to use longer names, like propertyId and parameterSpec

> Source/WebCore/platform/graphics/gstreamer/VideoSinkGStreamer.cpp:492
> +    GstCaps* currentCaps;

Please move this just before the g_object_get() call
