Description Antonio Trande 2013-11-20 21:15:13 UTC 
These errors appear by executing snappy:

 (snappy:27349): GLib-GObject-WARNING **: specified class size for type `ClutterGstVideoSink' is smaller than the parent type's `GstBaseSink' class size
(snappy:27349): GLib-GObject-WARNING **: cannot register existing type `GstObject'

(snappy:27349): GStreamer-CRITICAL **: gst_element_register: assertion `g_type_is_a (type, GST_TYPE_ELEMENT)' failed

This type of warnings are caused by conflict between gstreamer-old and gstreamer1 when they are installed together (http://gstreamer.freedesktop.org/data/doc/gstreamer/head/faq/html/chapter-troubleshooting.html#idp55001184) so I tested snappy by using 'clutter-gst2' instead of 'clutter-gst', since 'clutter-gst' needs gstreamer-old in Fedora.

With 'clutter-gst2' those warnings disappearand snappy works.

Could there be other problems if I choose clutter-gst2 to compile snappy ?

Thanks.

Not sure. Let me check and let you know. I will check in a few hours.

Thanks.

I just did a small update in the code upstream and it all works fine with clutter-gst2. It needs this version of clutter-gst2, and won't work with the previous one.
Let me know if you see any compilation warnings.

Here you can see the RPM building log: http://www.fpaste.org/55725/

Thank you.

Antonio,

Have a minute to talk in IRC? I am bit confused by all the warnings in the RPM building log, and by the color coding (a lot of Red).

You can find me in freenode: luisbg @ #gstreamer

Thanks

'snappy-player' package has been validated in Fedora.
It will be an official package in few days.

Best regards.
