    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) (...)

  • Automated installation script of MediaSPIP

    25 avril 2011, par

    To overcome the difficulties mainly due to the installation of server side software dependencies, an "all-in-one" installation script written in bash was created to facilitate this step on a server with a compatible Linux distribution.
    You must have access to your server via SSH and a root account to use it, which will install the dependencies. Contact your provider if you do not have that.
    The documentation of the use of this installation script is available here.

  • Is it possible to use CSA decryption with FFMPEG ?

    11 mai 2020, par Sezertt

    First of all I am sorry if I ask the wrong questions.

    



    I am currently using vlc (libdvbcsa) to encrypt and decrypt live streams and save it to a ts file just by giving

    



    csa-ck= key

    



    on server side and

    



    :ts-csa-ck= key

    



    on client side. It works as expected.

    



    But I want to use ffmpeg to decrypt ts file and show(I can show normal ts files but not the ones with csa encryption). I tried many input options for ffmpeg with no success and then I realized that ffmpeg has nothing to do with csa and most of them are for aes.

    



    Am I wrong ? Can you lead me to a direction ?

    


  • Is the output ts file size when using ffmpeg convert rtmp to hls with adaptive bitrate too large ?

    21 juillet 2022, par bui the vuong

    I want to convert rtmp to hls that supports adaptive bitrate , when referencing in many sources I use this configuration , but I found the ts file size of 240 to 720 bitrates is larger than I thought , I thought src will have to be the maximum size or 720p , please explain to me why , and is it possible to reduce the file size ( does any option in ffmpeg increase it ) ? Thanks everyone.

    


    My ffmpeg command :

    


    ffmpeg -i rtmp://localhost:1935/$app/$name -async 1 -vsync -1
                    -c:v libx264 -c:a aac -b:v 256k -b:a 64k -g 2 -vf "scale=426:trunc(ow/a/2)*2" -tune zerolatency -preset ultrafast -crf 23 -f flv rtmp://localhost:1935/show/$name_240
                    -c:v libx264 -c:a aac -b:v 768k -b:a 128k -g 2 -vf "scale=720:trunc(ow/a/2)*2" -tune zerolatency -preset ultrafast -crf 23 -f flv rtmp://localhost:1935/show/$name_360
                    -c:v libx264 -c:a aac -b:v 1024k -b:a 128k -g 2 -vf "scale=960:trunc(ow/a/2)*2" -tune zerolatency -preset ultrafast -crf 23 -f flv rtmp://localhost:1935/show/$name_480
                    -c:v libx264 -c:a aac -b:v 1920k -b:a 128k -g 2 -vf "scale=1280:trunc(ow/a/2)*2" -tune zerolatency -preset ultrafast -crf 23 -f flv rtmp://localhost:1935/show/$name_720
                    -c copy -f flv rtmp://localhost:1935/show/$name_src;


    


  • converting a UYVY FFmpeg

    19 février 2013, par Engine

    I want to read and show a video using opencv. I've recorded with Direct-show, the Video has UYVY (4:2:2) codec, since opencv can't read that format, I want to convert the codec to an RGB color model, I readed about ffmpeg and I want to know if it's possible to get this done with it ? if not if you a suggestion I'll be thankful.
