  • 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 (...)

    8 mars 2023, par x27x

    I tried with this command :

    


    ffmpeg -i song.mp3 -af pan="stereo|c0=c0|c1=-1*c1" -ac 1 karaoke.mp3

    


    But the output was the music without the singer's voice

    


     :) Is this possible with FFMPEG ?
Is there an alternative ?

    


  • Unsuccessful streaming webm video with ffserver - dimensions not set

    5 juin 2015, par randomuser1

    I configured ffmpeg and ffserver. Now when I type :

    ffmpeg -f dshow -list_devices true -i dummy

    I get the list of video/audio devices :

    [dshow @ 00000000045db680] DirectShow video devices (some may be both video and
    
audio devices)
    
[dshow @ 00000000045db680]  "SF Camera"

    Using that I’m running the ffmpeg command :

    ffmpeg -rtbufsize 1500M -f dshow -i video="SF Camera":audio="Microphone (Realtek High Definition Audio)" http://10.172.180.195:8090/feed1.ffm

    but all I get is :

    Guessed Channel Layout for  Input Stream #0.1 : stereo
    
Input #0, dshow, from 'video=SF Camera:audio=Microphone (Realtek High Definition

http://10.172.180.195:8090/feed1.ffm: Invalid data found when processing input

    as the answer from my ffserver. And on the server console I get the following error :

    [ffm @ 0x7f90f4000750]dimensions not set
    
Error writing output header for stream "/feed1.ffm": Invalid argument
    
10.172.180.109 - - [GET] "/feed1.ffm HTTP/1.1" 200 79

    and that’s all, ffmpeg stops and returns to command line. Does anyone know what can be the problem here ?

    Oh and one more thing that might be helpful - this is my ffserver.conf file :

    <stream>              # Output stream URL definition

  • Requirement to trim video from front-end

    30 octobre 2023, par user20663233

    I have a specific requirement to implement video uploading from the front-end Next Js framework to a third-party application. During this process, it is necessary to trim the first 20 seconds of the video, store the trimmed segment, and subsequently transmit it to the server. While initially considering the utilization of the FFmpeg library for video trimming, I've come to realize that I require server-side support, as hosting FFmpeg locally is not a feasible option. Therefore, I am exploring alternative solutions that would allow me to accomplish video uploads from the front-end while meeting these requirements.
