Firefox won't play video unless you move the timeline cursor forward (2 posts)

    Hello!

    I'm trying to convert a podcast that we use for iTunes from PodPress to PowerPress, and so far, it's been going well, except that now I'm running into an issue with Firefox (I'm using version 28.0).

    Here's the video I'm trying to get working so that I can update the rest of them:

    http://vlog.winesensetv.com/australian-riesling-and-food-pairing/

    The first issue I had was that Firefox wasn't even showing the player, but we only have the m4v version of the video, so I converted and added a webm version. I seem to be able to play it if I move the cursor further along the timeline, but not if I just hit the play button.

    The video seems to work without issues on IE 11 as well as Chrome 33.0.1750.154, but they also worked fine before I added the webm version of the video.

    Am I missing something? Do you have any tips you can give me, or have you seen this before at all? I've already updated the .htaccess file with this just in case:

    # MIME types for Video
    AddType video/mp4 mp4 m4v f4v f4p
    AddType video/ogg ogv
    AddType video/x-flv flv
    AddType video/webm webm

    I don't know what else to try, though...

    Thanks in advance for your help!

    Take care!

    The following links should help you with tweaking your video and web hosting to work optimally for podcasting.

    and

    Firefox does not natively play H.264 video but as of recent it does support H.264 if the operating system supports it (aka Windows and Firefox may work). But your mileage may vary, it hasn't worked all that well for me either.

    In PowerPress we provide a webm option in addition to mp4/m4v, which almost solves the problem. The new problem is if Firefox things it can play m4v based on the OS but then the computer still cannot play it. There's no 100% silver bullet when it comes to video.

    Next thing is in PowerPress > Video player, make sure you're using the MediaElement.js player, it does the best job of getting the media to play depending on the browser and media file format.

    Now my advice. Go to PowerPress settings > basic settings, enable the option to provide your own embed in the episode entry box. Then post your video on YouTube in addition to distributing as a podcast. You can use the YouTube embed (solves the Firefox issues as of recent) and has a positive side effect on your SEO. You will see in these settings that you can use the embed in place of the default player in PowerPress, as well as provide it in addition.

    Check out the PowerPress podcast channels feature if you're thinking about distributing both video and audio.

    Lastly, what ever you do, do not host large files (audio or video) on the same server as your web site. Your site will come to a crawl when multiple folks download your video, which will make play back on the web impossible (if the file cannot be downloaded as fast as it's duration).
