โJust a short note on this. Thanks for putting in the effort on applying
the gstreamer update.
The last mention I saw about production environments indicate AOO was going
to CentOS 6.x for the next release. Unfortunately, I can not locate a
bonafide CentOS6.x repo containing gstreamer 1.0 for use directly as part
of the indigenous build environment. So, it may need to be included in the
external downloaded libraries in /main/external_deps.lst.
