Merge r155104 - [Qt][WK1] REGRESSION(r154988): compositing/video/vide…

…o-with-invalid-source.html

https://bugs.webkit.org/show_bug.cgi?id=120683

Patch by Andre Moreira Magalhaes <andre.magalhaes@collabora.co.uk> on 2013-09-05
Reviewed by Philippe Normand.

Do not set pipeline state to NULL on MediaPlayerPrivateGStreamer::loadingFailed()
otherwise the bus is flushed and we never get a GST_MESSAGE_ERROR when failing to
load uris.
Also restore previous behaviour (before r154988) of not invoking loadingFailed() for
all failed manual state change attempts.

* platform/graphics/gstreamer/MediaPlayerPrivateGStreamer.cpp:
(WebCore::MediaPlayerPrivateGStreamer::changePipelineState):
Do not call loadingFailed() if state change fails as all manual state changes are
now done with changePipelineState().
(WebCore::MediaPlayerPrivateGStreamer::play):
(WebCore::MediaPlayerPrivateGStreamer::pause):
(WebCore::MediaPlayerPrivateGStreamer::seek):
(WebCore::MediaPlayerPrivateGStreamer::handleMessage):
Restore previous behaviour (before changeset r154988) when calling changePipelineState().
(WebCore::MediaPlayerPrivateGStreamer::updateStates):
Do nothing if changing to READY on EOS (same behaviour as setting to NULL as it was before
changeset r154988).
(WebCore::MediaPlayerPrivateGStreamer::loadingFailed):
Do not set pipeline state to NULL so we properly get GST_MESSAGE_ERROR on loading failures.
