Can't play mp4 video using html5 video tag

Question

I am trying to present an mp4 video (h264) using html5:

<video width="320" controls>
            <source src="/home/nabil/FWork/hikvision/ch01_00000100068000101.mp4" type="video/mp4">
</video>

analyzing video codec with ffmpeg gives the following:

a possible relevant detail is that playing the video using ubuntu's default video reader (ffmpeg in the background) doesn't show any video controls

Your file is named .mp4, but ffmpeg thinks it is actually .mpg. It might be right.

Remux:

ffmpeg -i input.mp4 -c copy -movflags +faststart output.mp4

But before you do that get a modern ffmpeg. Yours is ancient. For Linux you can either download or compile.
