Created attachment 54783 [details] Attachment demonstrates the problem As in previous release, sound effects / music added in custom animation still don't work in the latest version of LibreOffice. Errors such as 'Failed to load plugin '/usr/lib/gstreamer-0.10/libgstffmpeg.so' are shown in terminal, even though the gstreamer ffmpeg package is installed.
Created attachment 55216 [details] Works Fine in this sample Joshua O'Leary: I can reproduce the problem with your sample and all my LibO / OOo versions, but it's not reproducible with a presentation I created "from the scratch" with l Dev-Installation of "LibreOffice 3.5.0 Beta2- WIN7 Home Premium (64bit) German UI [Build-ID : 8589e48-760cc4d-f39cf3d-1b2857e-60db978] or "LibreOffice 3.4.5 RC1 - WIN7 Home Premium (64bit) German UI [Build ID: OOO340m1 (Build:501)]". Linux only? What's your result with my sample?
DUP of or related to "Bug 40780 - Sound fails to play on custom animation"?
I have re-tested both mine and your test-cases under libreoffice dev 3.5.0beta2, and both test cases fail to play custom animation sound. However, sounds and videos imported using Insert>Movie and Sound work perfectly and the sound is played back as it should. It appears that custom animation sound is not properly implemented under Linux. However, I do get these errors when trying a presentation with custom animation sound: (soffice:2078): GStreamer-WARNING **: Failed to load plugin '/usr/lib/gstreamer-0.10/libgstffmpeg.so': /opt/lodev3.5/program/../ure-link/lib/libstdc++.so.6: version `GLIBCXX_3.4.11' not found (required by /usr/lib/libdirac_encoder.so.0)
reproduced in 3.5.1 on Fedora 64 bit. all as in comment 3. But from Gallery sound works.
