  • La sauvegarde automatique de canaux SPIP

    1er avril 2010, par

    Dans le cadre de la mise en place d’une plateforme ouverte, il est important pour les hébergeurs de pouvoir disposer de sauvegardes assez régulières pour parer à tout problème éventuel.
    Pour réaliser cette tâche on se base sur deux plugins SPIP : Saveauto qui permet une sauvegarde régulière de la base de donnée sous la forme d’un dump mysql (utilisable dans phpmyadmin) mes_fichiers_2 qui permet de réaliser une archive au format zip des données importantes du site (les documents, les éléments (...)

  • 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 (...)

  • using ffmpeg to record highest resolution offered by Facetime cameras (mac)

    7 mai 2017, par user1361529

    I am using the following code successfully to record a video feed from my mac

    ./ffmpeg -f avfoundation -framerate 30  -i "default" out.mp4

    This however seems to be recording video at the lowest resolution of 320x200

    My camera supports the following resolutions :

    [avfoundation @ 0x7ff7b2800000] Supported modes:
    
[avfoundation @ 0x7ff7b2800000]   1280x720@[1.000000 30.000000]fps
    
[avfoundation @ 0x7ff7b2800000]   640x480@[1.000000 30.000000]fps
    
[avfoundation @ 0x7ff7b2800000]   320x240@[1.000000 30.000000]fps

    I tried manually specifying the resolution using both -s and -video_size but that seems to just scale up the low res video.

    How do I get ffmpeg to pick my 1280x720 resolution ?

    thanks

  • Webcam with FFmpeg on Mac : Selected framerate (29.970030) is not supported by the device

    24 juillet 2016, par Galaxy

    There was a very strange problem on Mac when I tried to access the webcam using FFmpeg.
    For example :

    ffmpeg -f avfoundation -i "1" -framerate 60 -vcodec libx264 -preset veryfast -f flv rtmp://localhost:1935/hls/test

    No matter what framerate I set, the error was always the same.

1: Input/output error

    I’ve searched for this problem for many days but still can’t find any solution. I’m very confused now.

    I hope someone using Mac could try the similar command to access the webcam in order to see if this is a common problem.

  • Webcam streaming from Mac using FFmpeg

    22 juillet 2016, par Galaxy

    I want to stream my webcam from Mac using FFmpeg.

    First I checked the supported devices using ffmpeg -f avfoundation -list_devices true -i ""

    Output :

    [AVFoundation input device @ 0x7fdf1bd03000] AVFoundation video devices:
    
[AVFoundation input device @ 0x7fdf1bd03000] [0] USB 2.0 Camera #2

[AVFoundation input device @ 0x7fdf1bd03000] AVFoundation audio devices:
    
[AVFoundation input device @ 0x7fdf1bd03000] [0] Built-in Microphone

    The device[0] is the webcam I want to use.

    Then I tried to capture the webcam using ffmpeg -f avfoundation -i "0" out.mpg

    Output :

    [avfoundation @ 0x7fe7f3810600] Selected framerate (29.970030) is not supported by the device

0: Input/output error

    After that, I tried stream this webcam from my Mac using ffmpeg -f avfoundation -framerate 30 -i "0" -f mpeg1video -b 200k -r 30 -vf scale=1920:1080 http://127.0.0.1:8082/

    Output :

    [avfoundation @ 0x7f8515012800] An error occurred: The activeVideoMinFrameDuration passed is not supported by the device.  Use -activeFormat.videoSupportedFrameRateRanges to discover valid ranges.0: Input/output error

    I cannot capture or stream this webcam. However when I used the Facetime camera instead of this webcam, everything was OK. I’ve been searching for this problem for a few days, but still cannot fix it. Does anyone have experience with webcam and FFmpeg on Mac ?
