  • Les vidéos

    21 avril 2011, par

    Comme les documents de type "audio", Mediaspip affiche dans la mesure du possible les vidéos grâce à la balise html5 .
    Un des inconvénients de cette balise est qu’elle n’est pas reconnue correctement par certains navigateurs (Internet Explorer pour ne pas le nommer) et que chaque navigateur ne gère en natif que certains formats de vidéos.
    Son avantage principal quant à lui est de bénéficier de la prise en charge native de vidéos dans les navigateur et donc de se passer de l’utilisation de Flash et (...)

  • Live website to video

    25 janvier 2016, par Asaf Nevo

    I have a website which shows a slideshow of pictures using JS.

    The pictures objects are coming from a web service and are being updated from time to time.

    In few days, I doing a test with a potential client to present the pictures slideshow on his big LED screen.

    He’s using BSPlayer for the content on screen, an able to present a website, but it will never be a clean full screen (the X button and such will always be presents).

    He’s the most comfort with presenting a video rather than a website.

    One of my ideas of solutions was to check if there is a way to stream a content of a website.

    Googling it got me to a solution combined ImageMagic and FFMPEG which you can read about here

    My problem is that this solution only creates a slide show out of static pictures - which I can do, but i’m losing the dynamic part of my live slideshow.

    Is there a tool for capturing websites and converting them into a stream of videos ?

    Or maybe a workaround to achieve the same functionality ?

  • FFMpeg - how to encode a F4M manifest file to mp4

    20 novembre 2015, par Roee

    I’m working on a project, where we want to encode flash videos to mp4 (for example, we want to encode a f4v file), and live-stream them (which means we can’t just download all the f4f files, then encode them to a single mp4 and just then stream it. The encoding and streaming has to be done while downloading the files).

    If the format of the flash video is flv for example, FFMpeg can do what I’ve described without any problem. I just give the address of the flv file to FFMpeg, and it encodes and streams it as mp4.

    But, if the format of the flash video is something more complicated as f4v (which gets downloaded as many f4f files), I don’t have a single url to give to FFMpeg as input - I have many addresses of f4f files. I don’t even know how many f4f files the video has before playing it - it looks like the flash player just fetches the next f4f file when needed.

    I read online that there is a manifest file (its extension is f4m), that "describes" to the flash player which f4f files it should download and play, and what’s their playing-order and everything.

    My question is - if I have the url of this f4m file, what should I do in order to encode all its f4f files to mp4 ?
    I’ve tried to give to FFMpeg just the f4m file as input, but it doesn’t know what to do with it...

    I’ll really appreciate any response that might help, as I’ve been working on this issue for few days now and I still haven’t found any answer...

    Thanks,
    Roee.
