As its name implies, MP4 Player is an application that allows you to load videos with the MP4 format. But the lightweight tool also supports FLV, AAC and MP3 files.
The interface of the program is based on a standard window with a familiar layout. Media files can be imported by using either the file browser or 'drag and drop' method. Unfortunately, you cannot import multiple items to create a playlist.
So, you can use some basic media player functions, such as pause, adjust the volume, navigate back and forth within the clip, switch to full screen mode and stretch the image on the screen.
Additionally, you can open the right-click menu and configure Adobe Flash Player settings (e.g. hardware acceleration, privacy, local storage) along with global options.
The simple-to-use media player runs on a moderate amount of CPU and system memory, has a good response time and supports keyboard shortcuts. We have not encountered any problems in our tests; MP4 Player did not freeze, crash or pop up error dialogs.
On the other hand, the app has some limited features. For example, you cannot enable loop mode or set MP4 Player to automatically exit when the playback is over. Nevertheless, MP4 Player is a pretty straightforward tool for playing audio tracks and video clips.
