  • Multilang : améliorer l’interface pour les blocs multilingues

    18 février 2011, par

    Multilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
    Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela.

  • Ajouter des informations spécifiques aux utilisateurs et autres modifications de comportement liées aux auteurs

    La manière la plus simple d’ajouter des informations aux auteurs est d’installer le plugin Inscription3. Il permet également de modifier certains comportements liés aux utilisateurs (référez-vous à sa documentation pour plus d’informations).
    Il est également possible d’ajouter des champs aux auteurs en installant les plugins champs extras 2 et Interface pour champs extras.

  • Escape character "|" error (Linux command)

    22 mars 2013, par user1812668

    I'm trying to run a Linux command in Java.

    This is the command :

    "ffmpeg -i rtmp ://192.168.1.112/garage/stream26g -f mpegts -acodec libmp3lame -ar 48000 -ab 64000 -s 480x320 -r 30 -vcodec libx264 -b 544k -flags +loop -cmp +chroma -partitions +parti4x4+partp8x8+partb8x8 -subq 5 -trellis 2 -refs 0 -coder 0 -me_range 16 -keyint_min 25 -sc_threshold 40 -i_qfactor 0.71 -bt 200k -maxrate 544k -bufsize 544k -rc_eq 'blurCplx^(1-qComp)' -qcomp 0.6 -qmin 10 -qmax 30 -qdiff 4 -level 30 -aspect 480:320 -g 30 -async 2 - | vod - 10 stream/stream26g/sample stream/stream26g/stream.m3u8 http://www.tshizerbia.com//video/ 5" ;

    But it gives me an error :

    Unable to find a suitable output format for |

    And I don't know what is the problem

    I used this to run the command

    Process p = Runtime.getRuntime().exec(command);

    If I put \\| in the string the message error is :

    Unable to find a suitable output format for |

    How can I escape this character ? Any ideas ?

  • ffmpeg says : "option framerate not found"

    16 juillet 2013, par Jason

    Good afternoon.

    I've been trying to use ffmpeg to split a .mpeg into a sequence of .jpeg images. Please note that this is the inverse problem of the one specified here, but the problem I'm facing is not the same as the problem the author of that thread is facing.

    Specifically, I have tried all the following mpeg codecs available in my ffmpeg installation :

    DEV D  ffv1            FFmpeg video codec #1
    
DEVSD  ffvhuff         Huffyuv FFmpeg variant
    
DEVSDT mpeg1video      MPEG-1 video
    
D V DT mpeg1video_vdpau MPEG-1 video (VDPAU acceleration)
    
D V D  mpeg2_crystalhd MPEG-2 Video (CrystalHD acceleration)
    
DEVSDT mpeg2video      MPEG-2 video
    
DEVSDT mpeg4           MPEG-4 part 2
    
D V D  mpeg4_crystalhd MPEG-4 Part 2 (CrystalHD acceleration)
    
D V DT mpeg4_vdpau     MPEG-4 part 2 (VDPAU)
    
D VSDT mpegvideo       MPEG-1 video
    
D V DT mpegvideo_vdpau MPEG-1/2 video (VDPAU acceleration)
    
D VSDT mpegvideo_xvmc  MPEG-1/2 video XvMC (X-Video Motion Compensation)
    
DEVSD  msmpeg4         MPEG-4 part 2 Microsoft variant version 3
    
D V D  msmpeg4_crystalhd MPEG-4 Part 2 Microsoft variant version 3 (CrystalHD acceleration)
    
D VSD  msmpeg4v1       MPEG-4 part 2 Microsoft variant version 1
    
DEVSD  msmpeg4v2       MPEG-4 part 2 Microsoft variant version 2

    I've tried supplying ffmpeg with all different codecs to try to split an input .mpeg video file with 2548 frames into 2548 .jpegs, by using the -vcodec option :

    ffmpeg -r 2548 -i frames.mpeg frames_%06d.jpg -vcodec $codec

    where $codec is any codec among the ones listed above, e.g. ffv1, mpeg4, etc. However, all my efforts result in the following error :

    [NULL @ 0x1948f20] Value 4707126720094797824.000000 for parameter 'probesize' out of range

[NULL @ 0x1948f20] Value 4607182418800017408.000000 for parameter 'err_detect' out of range
    
Option framerate not found.  

    Which is weird, because I've actually specified the frame rate parameter through the -r switch. I googled a bit and it appears that this error was mentioned approximately a year and a half ago on the ffmpeg bug tracker but that information makes little sense to me because it's relevant to the devs. Curiously, if I interchange the position of the parameters and put -r after -i or even after -vcodec, the error message changes to :
