  • Script d’installation automatique de MediaSPIP

    25 avril 2011, par

    Afin de palier aux difficultés d’installation dues principalement aux dépendances logicielles coté serveur, un script d’installation "tout en un" en bash a été créé afin de faciliter cette étape sur un serveur doté d’une distribution Linux compatible.
    Vous devez bénéficier d’un accès SSH à votre serveur et d’un compte "root" afin de l’utiliser, ce qui permettra d’installer les dépendances. Contactez votre hébergeur si vous ne disposez pas de cela.

  • Merging RGB Channels in FFMPEG [migrated]

    14 octobre 2016, par Draconis

    I have three grayscale videos, representing the red, green, and blue channels from a video. I extracted them using the extractplanes filter, and sent them through different pipelines.

    Now I would like to combine them again. But while extractplanes is working perfectly, mergeplanes is not. My initial attempt was this :

    [r][g][b] mergeplanes=0x001020 [output]

    This interprets my RGB channels as YUV, which is not what I want. My next attempt was this :

    [r][g][b] mergeplanes=0x001020:rgb24 [output]

    But according to the error message, Only planar formats with more than one component are supported. (Same for all other RGB and RGBA pixel formats I tried.)

    Is there another way to put these channels back together ? Or some way to convince mergeplanes to output RGB ?

  • DISABLE post processing(ffmpeg) in youtube-dl(2020.01.24)

    1er février 2020, par user3515562

    I want to disbale post process in youtube-dl(2020.01.24).
    My batch file contains

    set /p ytlink=Enter the link of Youtube Video:-    
    youtube-dl -x -o D:\%%(title)s.%%(ext)s %ytlink%  
    pause  

    The youtube-dl first downloads webm file or any other file than use post process ffmpeg.exe to convert it.
    I want to disable post process.Their must be no post process happening after youtube-dl download.

    - x is the option to only download audio file of the YouTube video in webm format .There is no post processing involved.But youtube-dl by default tries to convert the webm file to some other format, which is post processing.Post processing of audio file by default is one that i want to disable

  • Video size streaming to YouTube with FFMPEG on Raspberry Pi 4

    14 juillet 2023, par mysterons

    I'm using FFMPEG to stream video to YouTube with my Raspberry Pi 4. It used to work well, but just recently YouTube has started displaying the video smaller than it should be with a black surround as pictured.
preview in YouTube studio

    


    The command I am using is :

    


    ffmpeg -re -i $path -r 24 -g 48 -pix_fmt yuv420p -x264-params kiyint=48:min-keyint=48:scenecut=-1 -video_size 1280x720 -b:v 2000k -b:a 128k -ar 44100 -acodec aac -vcodec h264_v4l2m2m -preset superfast -bufsize 960k -crf 28 -threads 4 -f flv rtmp://a.rtmp.youtube.com/live2/$key

    


    I thought -video_size 1280x720 should set the resolution that FFMPEG is outputting, but it's still displaying as in the picture. The videos themselves are 720p.

    


    I can't work out how to get YouTube and FFMPEG to understand the resolution of the video from one another and have it fill the frame.
