  • Ajouter notes et légendes aux images

    7 février 2011, par

    Pour pouvoir ajouter notes et légendes aux images, la première étape est d’installer le plugin "Légendes".
    Une fois le plugin activé, vous pouvez le configurer dans l’espace de configuration afin de modifier les droits de création / modification et de suppression des notes. Par défaut seuls les administrateurs du site peuvent ajouter des notes aux images.

  • Use FFMPEG to create video from jpeg, and index using vlc

    16 novembre 2011, par Greg

    OpenSuse 11.4
    FFMEG 0.8.5

    I'm using FFMPEG to create a 5 minute mpeg from about 2100 individual jpegs (7fps). I've been using the following command (OpenSuse 11.4)
    /usr/bin/ffmpeg -y -r 7.01 -i %03d-capture.jpg -s 800x600 -r 25 Event-3692-r1-s1-3.mpg

    Now I Try to open the file (In windows XP with VLC 1.1.11 Player).
    Media->AdvancedFileOpen
    *I select "Show more options" and set StartTime to 5s. I expect that the video should start 5 seconds in, but instead it starts at a seemingling random (although consistent) time of 30 seconds in.

    I also tried changing ffmpeg command to :
    /usr/bin/ffmpeg -sameq -y -r 7.01 -i %03d-capture.jpg -s 800x600 -r 25 Event-3692-r1-s1-3.mpg
    *This result in about a constant 2x offset (5sec => 10sec) (10s => 20s) etc. But filesize is also about 6x larger, which is a strain on my storage.

    I also tried
    /usr/bin/ffmpeg -y -r 7.01 -i %03d-capture.jpg -s 800x600 -r 25 -f mpegts Event-3692-r1-s1-3.mpg
    *This result in vlc not indexing at all into my video. Also not desired. Anybody have any clues what is going on here. It is very important for me to be able to use this VLC feature and have it work correctly.

    Thanks in advance

    checkasm : af_afir : Use a dynamic tolerance depending on values

    As the values generated by av_bmg_get can be arbitrarily large
    
(only the stddev is specified), we can't use a fixed tolerance.
    
Calculate a dynamic tolerance (like in float_dsp from 38f966b2222db),
    
based on the individual steps of the calculation.
    

    This fixes running this test with certain seeds, when built with
    
clang for mingw/x86_32.

    avformat/utils : Discard huge timestamps which would cause overflows if used in basic computations

    Allowing larger timestamps makes it impossible to calculate basic things like the
    
difference of 2 timestamps or their sum without checking each individual computation for
    
overflow.
    
This should avoid a significant number of overflow checks
    

    Fixes Ticket5136
