  • 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 (...)

  • Emballe médias : à quoi cela sert ?

    4 février 2011, par

    Ce plugin vise à gérer des sites de mise en ligne de documents de tous types.
    Il crée des "médias", à savoir : un "média" est un article au sens SPIP créé automatiquement lors du téléversement d’un document qu’il soit audio, vidéo, image ou textuel ; un seul document ne peut être lié à un article dit "média" ;

  • Configuration spécifique d’Apache

    4 février 2011, par

    Modules spécifiques
    Pour la configuration d’Apache, il est conseillé d’activer certains modules non spécifiques à MediaSPIP, mais permettant d’améliorer les performances : mod_deflate et mod_headers pour compresser automatiquement via Apache les pages. Cf ce tutoriel ; mode_expires pour gérer correctement l’expiration des hits. Cf ce tutoriel ;
    Il est également conseillé d’ajouter la prise en charge par apache du mime-type pour les fichiers WebM comme indiqué dans ce tutoriel.

  • using ffmpeg -f ffmetadata to get metadata for a stream [on hold]

    23 avril 2014, par user645402

    I have a stream that I can get the metadata for using ffmpeg :

    ffmpeg -i <stream url="url"> -f ffmetadata -
    </stream>

    This works great for the first song, but then returns. The issue is that the stream is from a radio station which plays song after song - i.e. the metadata is changing as time goes on. However, this command will only give metadata for the song currently playing and then exit.

    I would like it to keep flowing the metadata as it updates in the stream.

  • Error Converting MOV to MP4 (avconv/ffmpeg)

    29 avril 2014, par user3584988

    I use :

    avconv -i '/INPUT.MOV' -vcodec libx264 -vprofile baseline -acodec aac -strict experimental -r 24 -b 255k -ar 44100 -ab 59k 'OUTPUT.mp4'

    The conversion is done correctly and smoothly plays PC / MAC, but the video does not play on mobile devices.
    Does anyone have the same problem ? How to solve it ?

    Thanks in advance

  • ffmpeg HLS creation and segmentation results in "cannot decode" on iPad

    5 mai 2014, par jt_dylan

    I have the following code that plays on Mac Safari :

       
         
         
         

       <video controls="controls" width="480" height="270">
       
       <source src="http://d1ckv7o9k6o3x9.cloudfront.net/d54cfa01-eff2-4e86-946e-dc8b2ee4a7e8/media/  hls/MVI_5927.m3u8">
       </source></video>

    The url can be cut/pasted into the browser and works also but neither this code nor the url works in Windows Safari or iPad. Specifically on iPad I receive a cannot decode error. On Mac I have Quicktime installed so I tried that on Windows with no luck. The link that can be play on Mac is below.

    http://d1ckv7o9k6o3x9.cloudfront.net/d54cfa01-eff2-4e86-946e-dc8b2ee4a7e8/media/hls/MVI_5927.m3u8

    Browser Versions of software :
    Mac Safari : Version 7.0.3 (9537.75.14) (works)
    Windows Safari : Version 5.1.7 (7534.7.2) (doesn’t work - blank screen)
    iPad Safari : ios Version 7.1.1 (doesn’t work - cannot decode)

    Here is how I’m creating my mp4 (lgpl)
    I’m creating an mp4 with this command :
    ffmpeg -i input.mov c:v mpeg4 q:v 1 test.mp4

    I’m creating the hls using ffmpeg lpgl with this command :

    ffmpegcmd -re -y -i test.mp4 -map 0 -f segment -segment_list test.m3u8 -segment_list_flags +live -segment_time 1 -segment_list_type m3u8 test%05d.ts 2>&amp;1

    Now this works in Mac Safari with Quicktime installed but results in "cannot decode" if I try the url from ipad Safari.

    I then tried with libx264 to create the mp4 as h.264 with aac and then copy to mpeg2 container as follows :

    ffmpeg -i test.mov  -c:v libx264 -c:a libfdk_aac -preset slower -b:a 240k test.slower.mp4
    ffmpeg -i test.slower.mp4 -vcodec copy -f mpegts -bsf h264_mp4toannexb test.slower.ts
    ffmpeg -re -y -i test.slower.ts -map 0 -f segment -segment_list test.slower.m3u8 -segment_list_flags +live -segment_time 1 -segment_list_type m3u8 test.slower.%05d.ts

    This still produces the same results. Any idea what is wrong here ?

    Any help is much appreciated.

    Regards,
    jt_dylan

    Output from libx264 commands below :

    ffmpeg -i test.mov  -c:v libx264 -c:a libfdk_aac -preset slower -b:a 240k test.slower.mp4
