This might be https://bugzilla.gnome.org/show_bug.cgi?id=757285

Also try with glimagesink instead of an appsink for starters, and check
if 720p30 or 1080p30 shows the same behaviour.

Also try sync=false on the sink to see if you also see the same
behaviour I mentioned in the bug report.


Once we got those parts working, we can take a look at appsink :)
