  • 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.

    This allows (among other things) : implementation costs to be shared between several different projects / individuals rapid deployment of multiple unique sites creation of groups of like-minded sites, making it possible to browse media in a more controlled and selective environment than the major "open" (...)

  • convert code which uses javax.sound.sampled in android

    6 avril 2013, par adityag

    I want to mix two audio files in android. First a song from library and second a sound recorded from mic.

    To begin with, I tried doing it on desktop using JS Resources Audio concat Program

    Using this code, I can mix/merge/overlap 2 sound wav files on desktop when i use float mix mode (-f).

    Now I was trying to do this in android environment. But found that javax.sound.sampled.* ; used in this code is not supported by android.

    Can anyone guide me how to deal with this situation ?

    Thanks,

    -Aditya.

    PS : other approach i tried is trying to use some ffmpg. But frankly, I couldnt understand how to make it work to suit my requirement :(

  • avfilter : Add tonemap vaapi filter for H2S

    2 décembre 2019, par Xinpeng Sun
    avfilter : Add tonemap vaapi filter for H2S

    It performs HDR(High Dynamic Range) to SDR(Standard Dynamic Range) conversion
    
with tone-mapping. It only supports HDR10 as input temporarily.
    

    An example command to use this filter with vaapi codecs :
    
FFMPEG -hwaccel vaapi -vaapi_device /dev/dri/renderD128 -hwaccel_output_format vaapi \

    - i INPUT -vf 'tonemap_vaapi=format=p010' -c:v hevc_vaapi -profile 2 OUTPUT

  • FFMpeg takes up the whole cpu and spams log on bug encounter

    16 octobre 2017, par Robert Vangor

    I have FFMpeg working on backend of website converting image + music to video. Every once in a while (probably 1/200 files), someone uploads something and cpu is always at 100% spamming error into log and filling up the whole space on drive, making the app unusable.

    I have literally at least a bilion lines of this in log

    [png @ 0x50f0700] Invalid PNG signature 0x2020202020202020.
    
Error while decoding stream #0:0: Invalid data found when processing input

    Here is an example of command that caused it this time :

    ffmpeg -y -v error -loop 1 -r 1 -i image.png -i song.mp3 -vcodec libx264 -acodec copy -vf scale=trunc(iw/2)*2:trunc(ih/2)*2 -preset ultrafast -r 1 -shortest output.mp4

    What can I do if I don’t have a control over files that get converted ?
