Since Storpia Duo’s web explorer is implemented with standard HTML5, the video file that can be played in web is mp4 file and other formats of video file can’t be played.
Generally, mp4 file is the video file that are combined of the video, which is compressed with MPEG-4 AVC(H.264) codec, and the audio, which is compressed with AAC or mp3 codec. Because of that, even if it is same mp4 extension, it won’t be able to be played, depending on the video or audio codec.
Also, there might be a difference in playing video file by different browser version. So, please check the list below.
