video mp4should be used when you have video content in your file  If there is none  but there is audio  you should use audio mp4  If no audio and no video is used  for instance if the file contains only a subtitle track or a metadata track  the MIME should be application mp4  Also  as a server  you should try to include the codecs or profiles parameters as defined in RFC6381  as this will help clients determine if they can play the file  prior to downloading it
