    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.

  • Android ffmpeg fails on second run

    5 juillet 2017, par Ante Braovic

    I have a problem with https://github.com/WritingMinds/ffmpeg-android-java. It’s Java wrapper lib for ffmpeg on Android and is was working pretty good. But is seems that you can not run two video encodings in a row. Actually it will encode video only once in a lifetime. Every next time you try to encode a video it will freeze. This is the output that I get when it freeze :

    I’m not sure what is going on. It seems like ffmpeg leaves something after the first encoding that locks it for any future encoding. And it will work only if i uninstall and then reinstall application.

    • If you kill an app from background this issue remains.
    • If you kill it and restart the device issue remains.
    • If you use force quit in the settings the issue remains.

    Only reinstall enables me to encode new video once. After that nothing works.

  • Better performance ffmpeg android

    9 mars 2020, par Brbcod1

    I’m running this command on ffmpeg for android :

    -i MYVIDEO -map 0:s:0? -c:v copy -preset veryfast -c:a copy -hls_flags single_file outputFile.m3u8 -frames:v 1 -q:v 2 outImage.jpg -y

    this is the ffmpeg library I’m using
    FFmpeg-Android-Java

    The speed of this command on the device is around 0.0900x (maximum I got is 0.1000x) : I need the speed to increase.

    Is it possible to increase the performance of ffmpeg or it depends on the device ?

    Ideally, I would like the ’time’ parameter that you see in the output to match the elapsed time, so each second elapsed is one second processed (right now, it needs around 15/20 seconds before the ’time’ parameter reaches ’00:00:01.00’).

    What do you suggest ?

    This is the log of ffmpeg when running the command :
