Riva FLV Player is a small application that enables you to seamlessly play FLV files.

The interface of the program is very simple and lacks complex functionality. You can add a video by using the file browser or the "drag and drop" method, and it will automatically start playing.

So, you can use basic commands, such as pause, loop and volume adjustment. But you can also set the interface to always be on top, as well as navigate back and forth within a video, and change the language.

The tool uses a low-to-moderate amount of system resources. It doesn't contain a user guide but the program is so simplistic, beginners wouldn't need a help file to get started.

When we said Riva FLV Player lacks complex functionality, we were actually serious. You cannot even switch to full screen mode or create a FLV playlist, let alone configure any kind of settings.

From this point of view, Riva FLV Player loses in front of users, even if they are looking for a simple program. At least it didn't freeze, crash or pop up errors during our tests.

With all these considered, Riva FLV Player is a decent video player for FLV files. But it certainly needs to make some improvements. You should test it for yourself and see if it fits your needs.
