This is a short note for myself (also for the search engines).
- Download LibreOffice tarballs from https://www.libreoffice.org/download/
- Extract the RPMs and install the RPMs as per instructions here
- Delete or move libstdc++.so.6 in /opt/libreoffice3.4/ure/lib
The RPMs from LibreOffice install to /opt and it has its own copy of libstdc++.so.6. Unfortunately, this version is unable to link(?) to the GStreamer / FFMPEG libraries. By removing the libstdc++.so.6 file from /opt LibreOffice is forced to use the system libstdc++.so.6. Now, LibreOffice can use video files in Impress with no problem.
I don't know what instabilities this may introduce LibreOffice, use at your own risk.
