    4 février 2011, par

    Ce plugin vise à gérer des sites de mise en ligne de documents de tous types.
    Il crée des "médias", à savoir : un "média" est un article au sens SPIP créé automatiquement lors du téléversement d’un document qu’il soit audio, vidéo, image ou textuel ; un seul document ne peut être lié à un article dit "média" ;

  • Inputing a List of Files for Concatenation with Node.js Module fluent-ffmpeg

    26 juin 2018, par carpiediem

    Version information

    • fluent-ffmpeg version : 2.1.2
    • ffmpeg version : 3.4.2
    • OS : Windows 10

    Code to reproduce

    ffmpeg('C:/path/to/list.txt').mergeToFile('C:/path/to/out.mp4', 'C:/path/to/temp');

    list.txt :

    file 'C:/path/to/chunk01.ts'
    
file 'C:/path/to/chunk02.ts'
    
file 'C:/path/to/chunk03.ts'
    
file 'C:/path/to/chunk04.ts'

    Note : I’ve tried both absolute and relative paths, with the same result.

    Expected results

    A video file at C:/path/to/out.mp4 that matches the 4 files in list.txt, concatenated end-to-end.

    Observed results

    An empty file at C:/path/to/out.mp4 with 0 duration and only 15kB in size. No errors were thrown.

    This is the command that I’m trying to duplicate (it works as expected, with relative paths in list.txt) :

    C:/path/to> ffmpeg -f concat -i list.txt -c copy out.ts

    stdout & stderr

    stdout was empty. stderr is copied below (with file names modified to match the ones above) :

  • How to generate m3u8 file and list of TS segment files using ffmpeg for wmv and avi video files

    26 avril 2018, par Sat

    I am able to generate m3u8 and list of segment(.ts) files from mp4 video file using following ffmpeg command

    ffmpeg -i Bee_Free.mp4 -codec copy -vbsf h264_mp4toannexb -map 0 -f segment -segment_list free.m3u8 -segment_time 10 free%03d.ts

    I am using the same command to generate m3u8 and ts files from .wmv and .avi files

    command for .avi file

    ffmpeg -i PalivalaBadraVatakam.avi -codec copy -vbsf h264_mp4toannexb -map 0 -f segment -segment_list palivaala.m3u8 -segment_time 10 palivaala%03d.ts

  • Choose download resolution in m3u8 list with ffmpeg

    31 mars 2024, par Bruno Andrade

    I'm trying to download video from a m3u8 playlist using ffmpeg but I do not know how to choose the resolution to download. Currently the command is downloading the highest version

    



    the command I am using is :

    



    /home/user/bin/ffmpeg -user_agent "Mozilla/5.0 (Windows NT 10.0; WOW64; rv:49.0) Gecko/20100101 Firefox/49.0" -i "https://sitevideo.com/list.m3u8" -c copy "/home/file/video.ts"


    



    My list is this

    



    #EXTM3U
#EXT-X-VERSION:3
#EXT-X-STREAM-INF:BANDWIDTH=400000,NAME="low"
size1.m3u8
#EXT-X-STREAM-INF:BANDWIDTH=800000,NAME="med"
size2.m3u8
#EXT-X-STREAM-INF:BANDWIDTH=1900000,NAME="best"
size3.m3u8
