I am a NEW YOUNG DEVELOPER.I do not know why, but all my mp4 stopped working when loaded with Windows Media Player. I found this out through trying to implement my first Html 5 Video ...
<!-- <video width="248" height="120" controls><source src="/resources/video.mp4" type="video/mp4"></video> -->
... and all I get is a message saying invalid source.
IS THIS AN ISSUE WITH THE CODE, OR THE VIDEO CODEC OR WHAT ????
