Want to view mp4 videos with Webview as used in our app(jAlbum). Webview
works very well when viewing jpegs generated by jAlbum. However it does not
display mp4 videos. Those videos are readily displayed by Mozilla Firefox
43.0.3 running on openSUSE Linux v13.2, see screen shot.

jAlbum/Webview fails to play the same video, which is attached.
Webview is invoked through jAlbum, which uses the following version of Java:

:~> java -version
java version "1.8.0_72"
Java(TM) SE Runtime Environment (build 1.8.0_72-b15)
Java HotSpot(TM) 64-Bit Server VM (build 25.72-b15, mixed mode)
:~>

Step to reproduce the problem:

login to a recent Linux distro, and invoke the WebViewDemo.jar(available at
http://jalbum.net/download/WebViewDemo.jar)
as follows and point it to:

Webview aborts with the following error:
