Before I raise an issue on Bugzilla, I would like confirmation of the following 
problem:

Using AOO 4.1.3 running on Xubuntu 16.04.1 I am not able to get Impress to play embedded 
videos.  Any attempt to embed an .avi or an .mpg file is blocked by "The format of 
the selected file is not supported" message and the file will not insert on the 
slide.  The .avi and .mpg files play perfectly using the system video player (Parole) or 
VLC.  From memory this problem occurred with AOO 4.0.0 - I have older presentations 
prepared in 2008 in which these embeddings worked correctly, but such presentations do 
not play in current AOO 4.1.3.  I have tried a number of different .avi and .mpg files, 
all to no avail within Impress.

I have checked using the same multimedia files on AOO 4,1.3 running on Windows 
XP - they work correctly

My workaround is to insert a hyperlink to the .avi/.mpg files, which calls the 
system video player.  This is a bit clunky, but at least the videos get shown.

Would other users please confirm if this problem shows up on other linux 
versions (please indicate linux distro and version) so that I can post as 
detailed an issue as possible on Bugzilla.

IMHO it's the old Java Media Framework issue. In former Sun times the JMF [1] was choosen for Linux-based OS to manage multimedia files. Maybe it was decided to use a Java-based implementation instead of a Linux-native one like gstreamer. But at the end I don't know why. At the moment it is as it is.

I don't know if the JMF functions are still part of a current JRE. If not then we have a possible root cause that it is no longer working.

PS:
If you want to know, I'm working on Fedora 25 and AOO 4.1.3.
