However, you will not be able to meet your goal of supporting "any format file multimedia".

I want read, play MP4 file (include video and audio data), but VideoFileReader cant read audio from this file. (dont support read audio in mp4 file, this note from matlab document) Do you have any other method for read, play mp4 file with video and audio the same time

The limitation is not on all .mp4, it is on compressed .mp4

"Do you have any other method for read, play mp4 file with video and audio the same time"

No. VideoFileReader is the only supported method, and as best I can recall at the moment there are no relevant methods in the File Exchange.
