I didn't find any official mention of ObjectusVideo being used for volleyball. As far as I can see, the application has a demo version, so you can try it out and see if it works before spending your money.
In case you need an alternative solution, Hudl is one of the best services when it comes to video analysis for sports like Volleyball, Handball, etc. To use it, you'll also need the Hudl Mercury client in order upload your videos to the service.
