  • MediaSPIP Player : problèmes potentiels

    Le lecteur ne fonctionne pas sur Internet Explorer
    Sur Internet Explorer (8 et 7 au moins), le plugin utilise le lecteur Flash flowplayer pour lire vidéos et son. Si le lecteur ne semble pas fonctionner, cela peut venir de la configuration du mod_deflate d’Apache.

  • 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) (...)

  • Alternatives to Facebook 360 Encoder for Spatial + Headlock Encoding ?

    31 juillet 2023, par Robert N

    Unfortunately FB 360 Encoder is no longer being worked on with no alternatives that I can find & right now I cannot get it to work on mac.

    


    I am looking to combine two stems as per the tutorial here - 1 spatial audio (16channel) with 1 headlock audio (stereo) for a 180 stereo (side by side) video in the highest quality allowed for a Meta Quest 2 headset.

    


    FFMPEG recipes are preferred but paid alternatives are welcome. So far the best I could find for encoding was "use the old software" but even if it worked, I do not trust out of date/dead software for production : Facebook 360 Encoder Error - FFmpeg libavdevice.57.dylib (not a mach-o file)

    


  • FFMpeg : How to stream to Facebook Live ? [closed]

    22 mars 2024, par Thomas Carlton

    I have ffmpeg on Windows.

    


    I would like to stream an mp4 file to Facebook Live. The video has an audio track.

    


    I am running the following command :

    


        ffmpeg 
    -re -i video.mp4 
    -acodec libmp3lame 
    -b:a 128k 
    -pix_fmt yuv420p 
    -profile:v baseline 
    -bufsize 6000k 
    -maxrate 1500k 
    -deinterlace 
    -vcodec libx264 
    -preset veryfast 
    -g 30 
    -r 30 
    -f flv 
    -flvflags no_duration_filesize 
    "rtmps://live-api-s.facebook.com:443/rtmp/mykey"


    


    This command works for exactly 14 frames and then it stops.

    


    enter image description here

    


    Then, I'm getting the following error saying "Conversion failed".

    


    enter image description here

    


    I tried to stream to AWS IVS. But I'm getting the exact same error.

    


    What is wrong with my command ?

    


  • avio_open2 fails randomly for RTMPS Facebook live streaming

    3 janvier, par Usama

    I am trying to re stream a video to Facebook RTMPS endpoint and , facing an issue specifically with Facebook's RTMPS endpoint . I have tried with linkedin RTMPS endpoint and its working fine , but Facebook end point some times works and fails some times its totally random . The avio_open2 call sometimes fails randomly, returning a -5 error. This only seems to happen with the Facebook endpoint .on ffmpeg log side I see that the handshake was successful , I don't understand the reason for failure here. (i am running in multithreaded environment )

    


    int ret = avformat.avio_open2(pb, url , AVIO_FLAG_WRITE, null, getOptionDictionary()) ;
