WHAT IS OGV?
The OGV format is an open video container format, which means it can be implemented by software developers without having to pay royalties. It was created by the Xiph.Org Foundation. If you don’t know how to play an OGV file, you’ll find a list of programs below that support playback of .ogv files. We also provide specifications for the OGV file type.
