HE4.7.1 can't play HTML5 video - SOLVED

I have used HE4.6 to publish a .exe file which can play HTML5 video well for years.
However, when I switch to HE4.7.1(I used same code), I get an error message:
Unsupported video type or invalid file path (when trying to play mp4)

My sample code:


Your browser does not support the video tag.

If I change path of mp4 file to specific local path (see below), it works fine too.

    <video width="320" height="240" controls>
        <source src="c:\myvideo.mp4"   type="video/mp4">
        Your browser does not support the video tag.
    </video>

Is there any one can help?

Or tell me how to get the heserver path and display on screen so that I can figure out what the virtual path is.

I have cheked the
VideoURL = http://heserver/myvideo.mp4
HE4.6 exe file and HE4.7.1 exe file both have same path.
HE4.6 exe file work fine, but the HE4.7.1 exe file show up an error message:
Unsupported video type or invalid file path.

Please help!

On which Windows version are you trying the code?

I used HE4.6 on Windows 8.1, and HE4.7.1 on Windows 10.

Even HE 4.6 shouldn’t be able to play HTML5 video on Windows 10 because Microsoft changed some things.
HE 4.8 will be able to play HTML5 audio and video fine.

When will you release HE4.8?

This month if everything is still OK

Great! Thank you!
And what’s the upgrade fee for HE4.6 to HE4.8 ?

To upgrade, make sure your maintenance is active. If it isn’t, go to http://www.htmlexe.com/accountrenew to get the discount price.

HTML Executable 4.8 can now play HTML5 video on Windows 10 successfully:
