mp3 support for HTML5 audio in Windows 7

  • We are running an application that is using HTML5 audio with .mp3 format. This is ok on all browsers except Opera. We are running the latest Opera version available.

  • Forgot to tell that we are running on Windows 7

  • mp3 requires browser vendors to pay fees. Opera is smaller than Google and hence can't provide mp3 playback support.
    But if you are providing video/audio content, you should know about two different formats being required to cover all major browsers. Read that up in just about any tutorial / explanation of HTML5 video/audio tags.

  • Thanks for your quick reply. However I have found that mp3 is working OK with Opera on Windows 8 etc ? Looking up tutorials about HTML5 audio, Opera is marked as supporting mp3.

  • You may have to enable proprietary media types in opera://flags/#proprietary-media-types-playback

  • However I have found that mp3 is working OK with Opera on Windows 8

    As you noticed support depends on what the operating system provides. Opera uses what's present there (if there is any).
    My previous answer holds true. If you want all browsers on all platforms, you need at least two formats.
