1) Ubuntu 16.04 delivers Qt 5.5.1
2) I am using Qt 5.6.0 official release (Linux x64). Not some PPA, nor Ubuntu stuff.

+  -gstreamer <version>  Enable GStreamer support
    With no parameter, this will attempt to auto-detect GStreamer 0.10 and 
1.0. GStreamer 1.0 is used by default when available. Use 0.10 or 1.0 for 
<version> to override auto-detection.

1.0 is the default since Qt 5.6, so it's probably an Ubuntu issue.
