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

but i want read video and audio simultanuously in a mp4 file, and videofilereader dont support, have other method ?

"The VideoFileReader object reads video frames, images, and audio samples from a video file. The object can also read image files."

"[I,AUDIO] = step(videoFReader) outputs the next video frame, I, and one frame of audio samples, AUDIO. This syntax requires that you set the AudioOutputPort property to true."

Considering that it is documented that it can read both video frames and audio samples, I do not understand why you indicate that it cannot do that?

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

[Walter Roberson]

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.
