Can Roku Play MP4? It All Depends!

As you may know, Roku Media Player is able to directly play videos stored on a USB drive which is formatted with the FAT16, FAT32, NTFS, EXT2, EXT3, and HFS+ file systems. But oddly, many people complained that Roku could display the MP4 files but refused to play them. How come the problem happened?

In fact, although different Roku devices support different formats based on firmware updates, MP4 format is undoubtedly supported as stated on Roku official webpage. What you need to know is that MP4 is just a container format that can encapsulate data compressed by various video and audio codecs. Once the certain codec used within the MP4 container is not recognized by Roku, the MP4 file will fail to play. Fortunately, however, this issue can be simply fixed through a process of video transcoding.
