I found gstreamer offcial have just announced 1.8.2 version. (“gstreamer.freedesktop.org”)
But CentOS 6 only support gstreamer 0.10. When will CentOS 6 support gstreamer 1.8?
When rhel6 does. That means: probably never.
I’ve no idea, but my CentOS7 system has both gstreamer (ver. 0.10) and gstreamer1 (ver. 1.4.5).
