I use HE4.6.1 to compile an (IE)ebook file with HTML5 video tag on a windows8.1 notebook.
The video in the ebook file can be run on win7, win8, win8.1 notebook verywell.
However, the video in the ebook file cannot be run on win10 notebook.
I get the error “Error: Unsupported video type or invalid file path”
My code sample (I add “blank” after “<”, so that you may see my code) :
< div class=“p_video” >
< video width=“320” height=“240” controls>
< source src=“media.mp4” type=“video/mp4”>
Your browser does not support HTML5 video.
< /video>
< /div>
