    Le plugin Chosen permet d’améliorer l’ergonomie des champs de sélection multiple. Voir les deux images suivantes pour comparer.
    Il suffit pour cela d’activer le plugin Chosen (Configuration générale du site > Gestion des plugins), puis de configurer le plugin (Les squelettes > Chosen) en activant l’utilisation de Chosen dans le site public et en spécifiant les éléments de formulaires à améliorer, par exemple select[multiple] pour les listes à sélection multiple (...)

  • Live stream videos on YouTube with ffmpeg?

    30 January 2021, by Manuservus

    What the program should do:

    


    It should download a video from an URL.

    


    Then put the video into a streaming interface (on the right side there should be the live chat from YouTube, in the middle, there should be the downloaded video).

    


    Next stream it live to YouTube.

    


    The process should repeat endless times.

    


    Download video from URL —> Stream it live to YouTube in a streaming interface -> repeat the whole process.

    


    Is this even possible in Python? If yes how?

    


    I would appreciate any help!

    


    PS: The stream should run smoothly without a break. That means: As soon as a video is finished, the next comes straight away.

    


  • Which library does Youtube use to process videos on their server?

    25 January 2020, by Ali Raza

    I want to know which library/component does Youtube use to process videos amazingly fast on their server ? I am using FFMpeg to process my video right now but it takes much time to process and create different qualities using bitrate.

    Are there any better alternatives to FFMpeg that can process videos faster like youtube ?

  • FFMPEG stream video to Youtube Live

    13 June 2022, by BlessedHIT

    I have a mov file and I'm using ffmpeg to stream it to youtube live using the following command,

    


    ffmpeg -re -i "episode.mov" -pix_fmt yuvj420p -x264-params keyint=48:min-keyint=48:scenecut=-1 -b:v 4500k -b:a 128k -ar 44100 -acodec aac -vcodec libx264 -preset medium -crf 28 -threads 4 -f flv "rtmp://a.rtmp.youtube.com/live2/YOUTUBE.LIVESTREAM.KEY"


    


    But im getting the following message on youtube,

    


    YouTube is not receiving enough video to maintain smooth streaming. As such, viewers will experience buffering


    


    My ffmpeg output showed my bitrate being between 800 - 1000 mbps, way lower than what i have specified in my ffmpeg command.

    


    I am using a not so powerful virtual machine, and so i thought this might be why i am not getting the desired bitrate.

    


    To overcome my hardware limitations, I then decided to encode the file for streaming using this command:

    


    ffmpeg -i episode.mov -c:v libx264 -preset medium -b:v 4500k -maxrate 4500k -bufsize 6000k -vf "scale=1280:-1,format=yuv420p" -g 50 -c:a aac -b:a 128k -ac 2 -ar 44100 episode.flv


    


    Then I stream copy the file using:

    


    ffmpeg -re -i episode.flv -c copy -f flv "rtmp://a.rtmp.youtube.com/live2/YOUTUBE.LIVESTREAM.KEY"


    


    And that seems to give me a stream that youtube is happy with.

    


    My question is, is there a way I can rewrite my ffmpeg command to livestream with the desired bitrate without needing to first encode my mov to another file or is adding more memory the only way forward here?
