  • 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 (...)

  • Installation en mode ferme

    4 février 2011, par

    Le mode ferme permet d’héberger plusieurs sites de type MediaSPIP en n’installant qu’une seule fois son noyau fonctionnel.
    C’est la méthode que nous utilisons sur cette même plateforme.
    L’utilisation en mode ferme nécessite de connaïtre un peu le mécanisme de SPIP contrairement à la version standalone qui ne nécessite pas réellement de connaissances spécifique puisque l’espace privé habituel de SPIP n’est plus utilisé.
    Dans un premier temps, vous devez avoir installé les mêmes fichiers que l’installation (...)

  • ffmpeg converted .mp4 videos are not playing on windows

    17 mai 2017, par Hemant Kumar

    I am converting videos with extension "flv","avi","mp4","mkv", "mpg", "wmv", "asf", "webm","mov","3gp","3gpp" into "mp4" for a better quality.

    Command I am using :

    ffmpeg -i /g9zyy2qg54qp1l5spo2-mergedFile.webm -strict -2 -vcodec libx264 -preset slow -vb 500k -maxrate 500k -bufsize 1000k -vf 'scale=-1:480 ' -threads 0 -ab 64k -s 640x480 -movflags faststart -metadata:s:v:0 rotate=0 /g9zyy2qg54qp1l5spo2-mergedFile7.mp4

    Videos are working fine everywhere except on Windows. No Video is working on window platform. I tried playing them on firefox, opera, even downloaded them and played on media player software but didn’t work at all.

    Can you please tell me codecs I should use that make the videos play on windows as well ?

  • Queuing up videos for live stream

    5 avril 2014, par Abdul Ali

    Would first like to tell that am new to streaming and ffmpeg.

    Would try to explain scenario as much as possible.

    A web service is intended to receive chunks of video from a user. those chunks need to be simultaneously sent to the web for live streaming for a seamless viewing.

    So the videos need to be queued up for streaming to the web so that it looks like a long single video. and the strict requirement is not to make any temp file on disk.

    Did read something about pipes but am completely alien to that concept as well.

    Kindly tell how / whether this can be achieved from FFMPEG or any other free tool .

    Language used is PHP . The received videos also need to be saved to disk in parallel for new users to see from start.

  • FFmpeg - Concat Videos with different rotations

    13 janvier 2024, par diadamalol

    I want to concat two Videos that have different Rotations 90 and 270.

    



    Here is the command that I used :

    



    ffmpeg -f concat -safe 0 -i list.txt -c copy output.mp4

    



    In list.txt are the paths to both videos.

    



    What I found out is that the Output Video gets the Rotation of the Video that is listed first in list.txt. So when the Video with Rotation 90 is first, the output video gets the Rotation 90. In the Output Video the second Video will be upside down.

    



    I tried the Flag -noautorotate, but nothing changed.

    



    How do I keep the rotation of all Videos, so that the rotation of the first isnt forced onto the others ?
