  • Les vidéos

    21 avril 2011, par

    Comme les documents de type "audio", Mediaspip affiche dans la mesure du possible les vidéos grâce à la balise html5 .
    Un des inconvénients de cette balise est qu’elle n’est pas reconnue correctement par certains navigateurs (Internet Explorer pour ne pas le nommer) et que chaque navigateur ne gère en natif que certains formats de vidéos.
    Son avantage principal quant à lui est de bénéficier de la prise en charge native de vidéos dans les navigateur et donc de se passer de l’utilisation de Flash et (...)

  • ffmpeg generate video from images timestamped

    11 février 2020, par user3262532

    I have a set of timestamped image as input and I want to generate a output video from it.

    My command is :

    ffmpeg   -f image2 -ts_from_file 1 -i './%*.jpeg'    './video.avi'

    As output I get many errors :

    ....
    
[mjpeg @ 0x5591f1d5f100] bits 121 is invalid
    
Error while decoding stream #0:0: Invalid data found when processing input

    The output video is not properly generates, the video file has the good framerate but visually the video is run too quick.

    I try many commands to get proper output but I can get it.

  • Redact parts of an audio file using python (FFMPEG)

    18 août 2020, par K3rn3l5

    I have a use case where I need to dynamically redact parts of an audio file using python. For example sometimes I may have to remove between timestamps 10 to 15 and other times between 5 to 7, 12 to 16 and 21 to 26 . I have tried looking at FFMPEG and think it may be possible with filters or chaining filters, but I am having trouble figuring out which ones to use and the combination. Any help or pointers will be highly appreciated. TIA !

    


  • Possible to change progress output interval in ffmpeg ?

    12 septembre 2021, par Thorts

    Example output :

    


    frame= 1234 fps= 25 q= 0.0 size= 10321 time = 00:02:12:31 bitrate= 301.1kbits/s speed=7.21x


    


    This output is updated around 4-5 times per second in the terminal.

    


    Is it possible to to change the interval for this status update ? Like once per second or once every 10 seconds.

    


    Reason being better overview when queueing several ffmpeg-jobs in a row.
Searched for 'interval' in the documentation but didn't find anything relevant.
