    Jolie sélection multiple
    Le plugin Chosen permet d’améliorer l’ergonomie des champs de sélection multiple. Voir les deux images suivantes pour comparer.
    Il suffit pour cela d’activer le plugin Chosen (Configuration générale du site > Gestion des plugins), puis de configurer le plugin (Les squelettes > Chosen) en activant l’utilisation de Chosen dans le site public et en spécifiant les éléments de formulaires à améliorer, par exemple select[multiple] pour les listes à sélection multiple (...)

  • split mp4-videos with ffmpeg as acurate as possible

    31 mai 2018, par atticus

    I’m trying to split a mp4-Video (Video-codec : h264 Audio-codec : mp3) with ffmpeg.
    I know there are many other Threads here with similar issues but in my case I’m trying to be as accurate as possible. My first command was ffmpeg -ss <starttime> -i  -to <duration> -c copy </duration></starttime>
    As I lernt about the issue with the Keyframes I created a command like this ffmpeg -ss <starttime> -i  -to <duration> -acodec copy -vcodec h264 </duration></starttime>
    As I’ve seen in some Forums it is possible to handle the keyframe-issue by inserting manually Keyframes but I’ve found nothing about how exactly this could be done and weather it really helps.?
    And how exact could it become if I re-encode the whole thing like in my second command and do I need to re-encode the audio Stream too ?

    EDIT : Or is it better to use the trim filter ?

    PS.:As I’m new to this network I hope not to have created a duplicate and to have it sorted into the right section. (And apologize my English skills)

  • Too many inputs specified for the "split" filter

    3 octobre 2018, par Sasidharan S

    I just tried to stitch 2 files and tried to get multiple outputs parallely :

    ffmpeg -i 1.mp4 -i 2.mp4 -filter_complex "[0:v:0] [0:a:0] [1:v:0] [1:a:0] concat=n=2:v=1:a=1, split=2[out1][out2]" -map '[out1]' -preset ultrafast -vn -b:a 128k -c:a aac  tes45.mp4 -map '[out2]' -preset ultrafast -vn -b:a 128k -c:a aac  tes46.mp4

    But it didn’t work :

    Too many inputs specified for the "split" filter.
    
Error initializing complex filters.
    
Invalid argument
