Bug 66936 – [GStreamer] fullscreen video pause/play fails

• Component: WebKitGTK
• Status: RESOLVED FIXED

[Philippe Normand]

In fullscreen the webkitsink goes to PAUSE asynchronously whereas autovideosink goes to PAUSE just fine. Then if we want to resume playback webkitsink tries to go to PLAYING again and is starved because buffers are blocked by the identity element upstream :(

I think we can just avoid the use of identity and in the webkitsink skip rendering of the buffers if we're fullscreen already.

Clearing r?, I'll provide a LayoutTest for this patch

Hum I failed to come up with a test showing the issue, in fact it's pretty internal to the MediaPlayerPrivate, the video appears freezed but the MediaPlayer continues to issue timeupdate events.

That's a different issue, bug 58548 is related to the segment handling and seeking. I need to get back to that one :)

Yes, please try on Qt!

View in context: https://bugs.webkit.org/attachment.cgi?id=105342&action=review

This looks sane to me.

> Source/WebCore/platform/graphics/gstreamer/VideoSinkGStreamer.cpp:377
>  GstElement*
> -webkit_video_sink_new(void)
> +webkit_video_sink_new(WebCore::GStreamerGWorld* gstGWorld)

This should be one line.

> Source/WebCore/platform/graphics/gstreamer/VideoSinkGStreamer.cpp:379
> +    GstElement* element = (GstElement*)g_object_new(WEBKIT_TYPE_VIDEO_SINK, 0);

Please use a C++-style cast or if GST_ELMENT is available, use that.

> Source/WebCore/platform/graphics/gstreamer/VideoSinkGStreamer.cpp:381
> +    WebKitVideoSink* sink = WEBKIT_VIDEO_SINK(element);
> +    sink->priv->gstGWorld = gstGWorld;

This should be one line.
