Subject: [PATCH] [GStreamer] Buffering ranges are reported incorrectly with GStreamer 1.0

https://bugs.webkit.org/show_bug.cgi?id=105319

Patch by Xabier Rodriguez Calvar <calvaris@igalia.com> on 2012-12-21
Reviewed by Philippe Normand.

We add the gPercentMax constant to select between 100 and
GST_FORMAT_PERCENT_MAX depending if we are compiling against
GStreamer 0.10 or 1.0 and we use that in the corresponding method.

Current tests should suffice.

* platform/graphics/gstreamer/MediaPlayerPrivateGStreamer.cpp:
(WebCore::MediaPlayerPrivateGStreamer::buffered): Added the use of
gPercentMax constant instead of 100 to have the different code
paths for GStreamer 0.10 and 1.0.
