HTML 5 Video tag don't play mp4 videos



  • Hello from Germany, i use the 32bit Version on Windows 8.1 64bit System and the video with mp4 on follow side can't be run. What is the problem or can't Vivaldi play html 5 video tags with mp4? All other Browser can play the file. http://broscheid.com/css/videos/VideoSnippet/VideoSnippet.html Greetings



  • Vivaldi as modern browser can play MPEG-4 in HTML5 element video. In your case it is not the browsers fault.

    The webserver of the page Microsoft-IIS/7.5 is broken. I hope it is not your own misconfigured server.

    Please Inspect this in Vivaldi:
    Open webpage in Vivaldi
    Open Developer tools with Ctrl Shift I
    Select the tab Network
    Reload Page with Ctrl F5
    Select in left pane the Name SnippetServer.mp4
    Select in right pane Headers

    See Response header:

    It sends the wrong MIME type!
    video/x-mp4 is not a correct mimetype for a MPEG-4 Video!
    See for correct types at http://www.iana.org/assignments/media-types/media-types.xhtml#video

    Please inform the admin of the server for setting the correct MIME type to video/mp4 and all is fine.



  • That was it! Thx a lot.

    No isn't my own Server, it is from my Provider 1&1. But i have admin rights to this Server. I have change the entry in the web.config and now it runs.

    But i wonder how it could runs under chrome firefox and ie… So what it goes.

    I like Vivaldi for his performans, faster than the other!

    Good job you make there!! Thanks and Greetings



  • It is better to use the correct MIME types than forcing browsers to guess or sniff, because that may result to security problems.

    That is the job of a person who owns a server: to do the right work. ;)

    PS: Freut mich, dass es klappt.
