  • Other interesting software

    13 avril 2011, par

    We don’t claim to be the only ones doing what we do ... and especially not to assert claims to be the best either ... What we do, we just try to do it well and getting better ...
    The following list represents softwares that tend to be more or less as MediaSPIP or that MediaSPIP tries more or less to do the same, whatever ...
    We don’t know them, we didn’t try them, but you can take a peek.

  • script ubuntu lucid : x264

    4 mars 2012

    Dans le log du script d’installation j’ai cette erreur :

    Téléchargement, compilation et installation de x264

    1. Initialized empty Git repository in /usr/local/src/x264/.git/
    2. Package x264 was not found in the pkg-config search path.
    3. Perhaps you should add the directory containing `x264.pc’
    4. to the PKG_CONFIG_PATH environment variable
    5. No package ’x264’ found
    Télécharger

    si je tape "echo $PKG_CONFIG_PATH" j’ai une ligne vide

    je suppose que la suite est en rapport :

    1. Makefile :3 : config.mak : Aucun fichier ou dossier de ce type
    2. cat : config.h : Aucun fichier ou dossier de ce type
    3. ./configure
    4. Found yasm 0.8.0.2194
    5. Minimum version is yasm-1.0.0
    6. If you really want to compile without asm, configure with —disable-asm.
    7. make : *** [config.mak] Erreur 1

  • Using ffmpeg with Python3 subprocess to convert multiple PNGs to a video

    17 décembre 2016, par ylnor

    I am using Python3, subprocess and ffmpeg to convert multiple PNG images into a single video.

    I have 400 PNG numbered as "00001.png".

    This call for one single specific image to a a one-frame-video works :

    subprocess.call(["ffmpeg","-y","-r","24","-i", "00300.png","-vcodec","mpeg4", "-qscale","5", "-r", "24", "video.mp4"])

    However, when I try some methods seen online for calling all of my images formated as "#####.png" using "%05d.png" as below, it does not work anymore :

    subprocess.call(["ffmpeg","-y","-r","24","-i", "%05d.png","-vcodec","mpeg4", "-qscale","5", "-r", "24", "video.mp4"])

    I receive the error : "%05d.png: No such file or directory".

    I have the feelling that the above syntax is proper to Python2 and not working on my python3 but can’t find the correct python3 syntax anywhere.

    Thanks in advance for your help

  • How to run ffmpeg command from the client side ?

    12 janvier 2017, par Debraj Biswas

    I am trying to make an online examination portal. When students start the exam, their webcam will start automatically and record the stream live and store in the server. Invigilators will either watch the students live or they can watch the saved live streams later.

    After many research on various technologies I came across this link. It uses Node JS with websockets and ffmpeg. I ran the ffmpeg command and it streamed the live video successfully.

    But the problem is, in order to live stream, the students have to have ffmpeg installed in their system and they should run the command directly from the terminal. So how can I change this ? The students will live stream from their browser, because this is a web portal. If we put this command in a PHP script, then the command will run at the server side. But client side command should run in this case. How can I run command from client side ?

    Any suggestions will be helpful.
