  • Les vidéos

    21 avril 2011, par

    Comme les documents de type "audio", Mediaspip affiche dans la mesure du possible les vidéos grâce à la balise html5 .
    Un des inconvénients de cette balise est qu’elle n’est pas reconnue correctement par certains navigateurs (Internet Explorer pour ne pas le nommer) et que chaque navigateur ne gère en natif que certains formats de vidéos.
    Son avantage principal quant à lui est de bénéficier de la prise en charge native de vidéos dans les navigateur et donc de se passer de l’utilisation de Flash et (...)

  • Script d’installation automatique de MediaSPIP

    25 avril 2011, par

    Afin de palier aux difficultés d’installation dues principalement aux dépendances logicielles coté serveur, un script d’installation "tout en un" en bash a été créé afin de faciliter cette étape sur un serveur doté d’une distribution Linux compatible.
    Vous devez bénéficier d’un accès SSH à votre serveur et d’un compte "root" afin de l’utiliser, ce qui permettra d’installer les dépendances. Contactez votre hébergeur si vous ne disposez pas de cela.

  • ffmpeg merge audio of two videos

    19 juillet 2018, par Venom

    i have a couple of videos and i want to make them smaller to save some space... therefore i really would like to merge the audiotracks of file1 into file2
    so that i can later on delete file1 because the picture content of both videos is the same...
    Is there a way to accomplish that with ffmpeg ? With this cmd i would have 2 video/audio tracks in one file so this is NOT what i want.

    ffmpeg -i file1.mp4 -i file2.mp4 -c copy output.mp4

    i only want the audio of file1 and the video and audio of file2 merge into one file...

    Thanks

  • How to record custom videos in Android [on hold]

    27 novembre 2013, par Chirry

    Context :

    Right now I have an App which takes the video from the camera and put some custome bitmaps on the same SurfaceView.

    Question :

    What I'd like is to record a video with the camera view and the custom Bitmaps on it.

    I have heard about AndroidFFmpeg third party codec to record videos, but I don't know how, I mean, is there any function on the AndroidFFmpeg to record videos in Android ?

    Hope you can help me with one this as there is not much information on the internet !

  • Adding cross fade between concatenated videos

    6 novembre 2022, par SyndicatorBBB

    I'm using the following command to concat multiple videos together :

    


    ffmpeg -i 1.mp4 -i 2.mp4 -i 3.mp4 -f lavfi -t 0.1 -i anullsrc -filter_complex "[0:v]scale=3840:2160:force_original_aspect_ratio=decrease,pad=3840:2160:-1:-1,setsar=1,fps=30,format=yuv420p[v0]; [1:v]scale=3840:2160:force_original_aspect_ratio=decrease,pad=3840:2160:-1:-1,setsar=1,fps=30,format=yuv420p[v1]; [2:v]scale=3840:2160:force_original_aspect_ratio=decrease,pad=3840:2160:-1:-1,setsar=1,fps=30,format=yuv420p[v2]; [v0][3:a][v1][3:a][v2][3:a]concat=n=3:v=1:a=1[v][a]" -map "[v]" -map "[a]" -c:v libx264 -c:a aac -movflags +faststart output3.mp4


    


    How can I modify my command so that I can include cross fade transition between each video ? Notice I need a constant duration of fade between all the videos, no need special effect between two videos.
Also I don't care about audio, only care about the transitions between videos.

    


    Is there a generic way that I don't need to specify the exact time when to start the next transition ? Like saying between each video do cross fade transition.
