    No, it isn’t the same as MediaElement player but to have more features, more control and a couple of skinnings, install MediaElement.

    The reason I was installing MediaElement player is to have subtitles feature but then, MP4 video doesn’t work on MediaElement plus it was last updated over a year ago. Not sure if the support for this plugin is discontinued.

    MP4 videos play fine on default wordpress player.

    Gary, thank you for helping! I have been confused on this for a while 🙂 here is my thought about your problem, maybe it is about preparing MP4 file
    1) choose MP4, H264, AAC
    2) use QTIndexSwapper2 ( http://renaun.com/blog/code/qtindexswapper/ )to move the index at the beginning of the file.

    just my thoughts. good luck!

    Indeed, it could be that. I used Handbrake to encode the video to MP4 format but in the end, due to a lack of support (or lack of standard) for subtitles in browsers, I decided to go on the safer route of burning the subtitles into the video with Xvid4psp.

    I have also tried out many media players plugin for wordpress but couldn’t find an ideal one. But wordpress player does a great job of playing mp4 video files well on Firefox and other browsers plus videos loaded quickly so why dig deep beyond wordpress’ own player when I can simply burn the subtitles in videos?

    Anyhow, it seems that I still have some to learn about preparing the videos for the internet, especially with mobile devices.

    Thanks for your advice

    Firefox requires .webm format as an alternative to .mp4 (as far as I know).

    According to wordpress, MediaElements.js is at the core of video functionality in wordpress:

    I’m fighting the same issue as you. Mine appears a little more complex as I get a flash fallback in Moz in windows xp, but just a spinning load screen in Win7 on Moz. By installing the plugin to get subtitle support, you may actually be downgrading the js code to a previous version. Try installing:

    to access and configure your subtitles
