The HTML5 video added in the webpage was playbacking successfully in my developer environment. But, why deployed to client's Azure web app it was not playing at all. I suspected for any script errors but browser's console window was empty. Later I figured out that we need to specify mime type in web.config of the website for this to work.
Below is a quick peek of web.config file.
<configuration><system.webServer><staticContent><remove fileExtension=".mp4" /><mimeMap fileExtension=".mp4" mimeType="video/mp4" /><remove fileExtension=".webm" /><mimeMap fileExtension=".webm" mimeType="video/webm" /><!-- Add your mime type here --></staticContent></system.webServer></configuration>
Hope this helps.
