  • Mediabox : ouvrir les images dans l’espace maximal pour l’utilisateur

    8 février 2011, par

    La visualisation des images est restreinte par la largeur accordée par le design du site (dépendant du thème utilisé). Elles sont donc visibles sous un format réduit. Afin de profiter de l’ensemble de la place disponible sur l’écran de l’utilisateur, il est possible d’ajouter une fonctionnalité d’affichage de l’image dans une boite multimedia apparaissant au dessus du reste du contenu.
    Pour ce faire il est nécessaire d’installer le plugin "Mediabox".

  • Rails FFMPEG - convert to webm gives error for encoder 'libvpx-vp9'

    7 mai 2019, par Milind

    I am testing video conversion to convert video file into mp4 and webm.
    I have also setup ffmpeg and compiled properly.Mp4 conversion succeeds but webm breaks always complaining as -

    The encoder 'libvpx-vp9' is experimental but experimental codecs are not enabled, add '-strict -2' if you want to use it.

    its strange as I aready have vp8 present -

  • How to compile ffmpeg to get only mp3 and mp4 support

    19 février 2019, par Enis Jasarovic

    I’m building Electron app and I use ffmpeg to convert m4a or webm files to mp3, and also to merge video only mp4 with m4a audio file to mp4.

    I am able to achieve this using [media-autobuild-suite] (https://github.com/jb-alvarado/media-autobuild_suite), using light build option, but the size of static files is arround 20mb and I’would like to shrink it a little bit more. I’ve compiled ffmpeg and ffprobe with this configuration.

  • FFmpeg error : Unable to find a suitable output format for ''

    11 juillet 2020, par Benjamin Basmaci

    I'm new to ffmpeg as well as Android programming. I'm trying to load a video from a URL and crop it with ffmpeg. I want to save that video to a file. This is the command I found online :

    &#xA;

    "-i " &#x2B; videoUrl &#x2B; "-filter:v crop=240:120:100:100 -c:a copy test.mp4"&#xA;

    &#xA;

    I have tried it and got the error Unable to find a suitable output format for &#x27;&#x27;

    &#xA;

    So I tried to narrow the possible cause down and tried these commands as well :

    &#xA;

    "-i " &#x2B; videoUrl &#x2B; " -c:v copy -c:a copy test.mp4"&#xA;"-i " &#x2B; videoUrl &#x2B; " -c:v copy test.mp4"&#xA;"-i " &#x2B; videoUrl &#x2B; " -c:a copy test.mp4"&#xA;"-i " &#x2B; videoUrl &#x2B; " test.mp4"&#xA;

    &#xA;

    So with that last one I basically boiled it down to the bare minimum of what a comment needs, as far as I know. But still, same result.

    &#xA;

    All of them give me the same error. Here is the full output I got via FFmpeg.getLatestOutput()

    &#xA;

    Why does ffmpeg assume that I have given it no output format and what I need to do to make this work ?

    I'm using implementation &#x27;com.arthenica:mobile-ffmpeg-full:4.2&#x27;.
