  • 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) (...)

    The following list represents softwares that tend to be more or less as MediaSPIP or that MediaSPIP tries more or less to do the same, whatever ...
    We don’t know them, we didn’t try them, but you can take a peek.

  • extract all frames of a video without any chroma subsampling

    8 janvier 2013, par user1444800

    I am looking to extract all frames of a video in jpeg format but in 4:4:4 format i.e. without any chroma sub sampling applied such that MCU is 8x8. I am not sure if there is a way to do this easily but I tried this :

    `ffmpeg -i Video.mpg Pictures%d.jpg`

    but this gives me images in 4:2:0 format. Other options is to convert them to RGB and later save it without any subsampling.

  • Can't access Google Cloud Platform hosted rtsp stream externally

    1er novembre 2023, par Nikos Daskalas

    I have been trying to host a video to rtsp stream on a gcp vm instance.

    


    My steps were :

    


    a) Set up an external ip to my vm, and setup firewall rules to allow traffick.

    


    b)Install mediamtx to my vm and start a server with ./mediamtx

    


    c)install ffmpeg and stream my video with : ffmpeg -i video.mp4 -rtsp_transport tcp -f rtsp rtsp ://externalip:8554/live.stream

    


    The stream runs locally, but when I try to access in with vlc or ffplay rtsp ://externalip:8554/live.stream, I cannot connect. I tried to ping the server from the client side, and it works ok.

    


    What am I missing ? Are there any more configurations I need to do to my project ?

    


  • Improve FFmpeg time ? conversion takes very long

    15 avril 2015, par Rubytastic

    I have several rules to convert a movie to several formats and create a preview image. Problem is the execution of these takes very long.
    Also the outputted quality is very low. I harvested these examples from several sources.

    What could be done to
    * improve speed
    * improve quality ?

     ffmpeg -y -i /file/$1.flv -acodec libmp3lame -ar 44100 -ac 1 -vcodec libx264 /file/$1.mp4
    
 ffmpeg -i /file/$1.mp4 -acodec libvorbis -aq 5 -ac 2 -qmax 25 -threads 2 /file/$1.webm
    
 ffmpeg -r 30 -i /file/$1.mp4  -vcodec libtheora -acodec libvorbis /file/$1.ogv
    
 ffmpeg -i /file/$1.mp4 -ss 3 -f image2 -vframes 1 -s 600x480 /file/$1.png
