  • Support de tous types de médias

    10 avril 2011

    Contrairement à beaucoup de logiciels et autres plate-formes modernes de partage de documents, MediaSPIP a l’ambition de gérer un maximum de formats de documents différents qu’ils soient de type : images (png, gif, jpg, bmp et autres...) ; audio (MP3, Ogg, Wav et autres...) ; vidéo (Avi, MP4, Ogv, mpg, mov, wmv et autres...) ; contenu textuel, code ou autres (open office, microsoft office (tableur, présentation), web (html, css), LaTeX, Google Earth) (...)

  • 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.

  • Support audio et vidéo HTML5

    10 avril 2011

    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 (...)

  • Use Windows ffmpeg to record audio output without using the StereoMix

    2 septembre 2016, par DevtelSoftware

    I am looking for a way to record the audio output (speakers) using Windows ffmpeg.
    I need to do this WITHOUT installing any extra dshow filters and without having the StereoMix input enabled (since this is not available on many computers).

    I have read in the ffmpeg documentation that the -map would allow redirecting an audio output so that ffmpeg sees it as an audio input but I can’t find any example of how to do that.

    In Linux I managed to do it like this :

    ffmpeg -f pulse -ac 2 -ar 44100 -i alsa_output.pci-0000_00_1f.4.analog-stereo.monitor -f pulse -ac 2 -ar 44100 -i alsa_input.pci-0000_00_1f.4.analog-stereo -filter_complex amix=inputs=2 test.mp4

    However I can’t find a similar way to do it in Windows and MacOSX.

    So in short, is it possible with the Windows ffmpeg to record audio from the speakers without extra dshow filters (out-of-the-box) ? Same question goes for MacOSX.

    Thanks !

  • FFmpeg file size while recording multiple windows at same time

    29 août 2021, par RuanS

    I'm currently recording 3 windows at once, and placing them next to each other, windows dimensions are : 400x500, 830x500, 830x500, using -c:v h264_nvenc to reduce the use of CPU.

    


    The first and second windows have very low frames change, the third window does change frames frequently.

    


    ffmpeg -f gdigrab -framerate 30 -i title="" -f gdigrab -framerate 30 -i title="" -f gdigrab -framerate 30 -i title="" -c:v h264_nvenc -qp 0 -c:a copy -vsync vfr -filter_complex hstack=inputs=3 output.mp4


    


    Doesn't need to be great quality, 'normal/medium' quality is enough, also, I'm recording only video, no audio.

    


    After 3min the file size was over 340MB, would like to ask if there are any better options in which I could be used to reduce the file size also CPU use (if possible).
