  • HTML5 audio and video support

    13 avril 2011, par

    MediaSPIP uses HTML5 video and audio tags to play multimedia files, taking advantage of the latest W3C innovations supported by modern browsers.
    The MediaSPIP player used has been created specifically for MediaSPIP and can be easily adapted to fit in with a specific theme.
    For older browsers the Flowplayer flash fallback is used.
    MediaSPIP allows for media playback on major mobile platforms with the above (...)

  • Support audio et vidéo HTML5

    MediaSPIP utilise les balises HTML5 video et audio pour la lecture de documents multimedia en profitant des dernières innovations du W3C supportées par les navigateurs modernes.
    Pour les navigateurs plus anciens, le lecteur flash Flowplayer est utilisé.
    Le lecteur HTML5 utilisé a été spécifiquement créé pour MediaSPIP : il est complètement modifiable graphiquement pour correspondre à un thème choisi.
    Ces technologies permettent de distribuer vidéo et son à la fois sur des ordinateurs conventionnels (...)

  • De l’upload à la vidéo finale [version standalone]

    31 janvier 2010, par

    Le chemin d’un document audio ou vidéo dans SPIPMotion est divisé en trois étapes distinctes.
    Upload et récupération d’informations de la vidéo source
    Dans un premier temps, il est nécessaire de créer un article SPIP et de lui joindre le document vidéo "source".
    Au moment où ce document est joint à l’article, deux actions supplémentaires au comportement normal sont exécutées : La récupération des informations techniques des flux audio et video du fichier ; La génération d’une vignette : extraction d’une (...)

  • How to combine 2 videos using either NReco ffmpeg ConvertMedia or just ffmpeg command line ?

    11 octobre 2016, par M. Ilchuk

    We have 2 videos : video1.webm and video2.webm.
    How to combine these two and get output.mp4 which contains video from video1.webm and audio from video1 and video2 ?

    Example :

    video1(audio1 in video1) + video2(audio2 in video2) = outputVideo(video1 + audio1 +audio2)

    image example

    The final video is available here, i’m able to read it from Safari on Mac OS, but it doesn’t work on iOS using AVPlayer or Safari.

    I also tried to play it using this sample code provided by Apple, however i get the following error :
    "The decoder required for this media cannot be found"

    Any help is appreciated

    edit 1

    I’ve edit the command line, and now i’m able to play the video using AVPlayer, but there is no sound...

  • How to use v4l2 scrcpy virtual webcam ?

    2 mars 2024, par Emma bundy

    I created a virtual camera v4l2 /dev/video21 and linked it to my notebook's default webcam /dev/video1 and it started working so far ok, then I mirrored the webcam I created in OBS-studio.

    


    and now I want to connect in scrcpy the virtual camera that I created that is active /dev/video21, but I don't know how to do that, what commands to give to use the v4l2 /dev/video21 camera from the computer on my cell phone.

    


    which is already mirrored on the computer screen via wireless

    


    I need help, who can help me I thank you immensely ! This is for my college studies

    


    I tried to do this several times but I couldn't, I use Fedora 37 gnome, I used ffmpeg to link the webcam /dev/video1 + /dev/video21, and I mirrored it in OBS-studio, but I don't know which command to give to send the /dev/video21 video stream to my cell phone, use the virtual camera created on the cell phone.
