  • 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.

  • ffmpeg create screenshots full of artefacts and completly illegible

    17 septembre 2020, par Hekimen

    I am using ffmpeg to create 15 screenshots from video with simple command

    


    ffmpeg -ss 10:00 -y -i 'video.mp4' -f mjpeg -vframes 1 -an 'image.jpg'


    


    command is executed 15x in row with different -ss time. But sometimes, completly randomly, images - all 15, even each of them is created by own process, are basicaly generated full of artefacts and completly illegible :
enter image description here

    


    I believe is not problem with video, as they are almost always different - codecs, bitrate, lenght, quality, resolution, etc. I was trying search similar problem, but only same problem i found was when images was created from real-time stream over UDP (problem with UDP transfer protocol), which is not my case as ffmpeg and videos are installed and stored on same HDD (centos OS). Otuput from ffmpeg command is also without any error. I am also unable reproduce this behavior, when i run process for screenshots again, all screenshots are created properly. My only suspicion is server load, screenshots are created on encoding server which have average load around 50% on CPU : enter image description here
Is it possible that when the CPU is fully loaded, ffmpeg can create broken images ?

    


  • Use FFMPEG without downloading full file

    19 août 2020, par servalex

    I'm generating thumbnails for a videos that are available from s3 and need to minimize traffic.
Frame is going to be from the first couple seconds of the video so the question : is there a way to get frame without passing the full file through network ?

    


    At the moment I'm passing video url to ffmpeg but seems like it downloads the whole file, not only first couple seconds.

    


    ffmpeg -ss 0 -noaccurate_seek -i {srcPresignedUrl} -vframes 1 -q:v 2 {outputFileName}

    


    I tried downloading first 10mb of the file and passing it, this works for some mp4 files, but fails on mov :

    


    ffmpeg.exe -ss 0 -i source.mov -vframes 1 -q:v 2 thumb.jpg

  • How to use FFMPEG for a whole directory ? (Example code i found on a different thesd doesn't work for me) [closed]

    17 juillet 2020, par TrainNutter

    I have discovered that FFMPEG is a thing and I'm wondering how i can compress many files in 1 bat file execution and that the newly compressed filed keep the same name as the Raw files and subsiquently replace the raw file in MP4 format

    


    I am wondering this as i have over 700GB of Raw videos spanning over 3+ years of recording youtube videos (just for fun) and that my 2TB hard drive is now almost full lol

    


    I Tried using this example but it didn't work for some reason

    


    for i in *.mp4;
    do name=`echo "$i" | cut -d'.' -f1`
    echo "$name"
    ffmpeg -i "$i" "${name}.mp4"
done


    


    Edit : I am using Windows 10
