.. continuing from osg-users list:
Hi Robert,
I don't fully understand how plugins works in OSG but at least I figured
out that Registry.cpp has no section for ffmpeg att all like other plugins
has.
I added this to Registry.cpp:
addFileExtensionAlias("ogv", "ffmpeg");
and then I was able to show videos with osgmovie and my own application
without explicitly loading ffmpeg plugin.
There is no USE_FFMPEG flag in cmake files and I don't know cmake well
enough to add it.
I don't know if this helps at all or is even correct analysis but this is
best I can think of :)
Regards,
Ari
