  • Multilang : améliorer l’interface pour les blocs multilingues

    18 février 2011, par

    Multilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
    Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela.

  • Video processing / playback with alpha channel in C# or C++ [closed]

    2 avril 2013, par Corylulu

    WHAT I'M AFTER

    I've been exploring the best ways to do this, but seem to keep running into hiccups when trying to playback video and then grab the frame with an alpha channel (ARGB) to then be further manipulated.

    I've gotten everything to work with AForge to then find out that the Alpha gets stripped out during the process. I considered OpenCV, but the Emgu CV has a different license that I can't use and I can't verify that OpenCV can read Alpha channels as well.

    I looked into FFMPEG .NET wrappers, but haven't found any that are out of their alpha phase or have a license I can use them with (since this could be used for commercial purposes and can't be open sourced)

    So I'm looking for a library that is preferably C# or C++ that can play a .MOV or .AVI while preserving it's alpha channel when I make it into a Bitmap.

    SUMMARY [TL ;DR]

    I'm looking for library / sample code

    • Written preferably in C#, C++ as a fallback. Hopefully easy enough to use.
    • Can playback AVI and MOV files
    • Will preserve the alpha channel
    • Will allow me to access each frame's ARGB values directly
    • Preferably something that uses the FFMPEG library since it's able to read most formats I need

  • Android processing a video to CMYK

    28 juillet 2014, par bigben619

    I am working on a project and in that project I need to be able to :

    1. get a frame of a video
    2. change it to a CMYK
    3. try to render that frame

    Do you guys have any suggestions ?

    To get the frames I think I can use ffmpeg.
    I think the person that wrote
    Android processing a video, YCrCb frames to video
    can help me but I’m open to any suggestions.

    I appreciate all the help I can get, thank you

  • On the fly mp4 processing

    26 août 2014, par Max Grigoriev

    Is possible to make such thing ?
    I have mp4 files. Client login and start viewing them. I should add client login name and other information to the video output on the fly. It’s easy to make offline - process all files by ffmpeg and save new mp4 files. But it doesn’t work for me because there’re real time information which can’t be added offline.
    Is it possible to make mp4 processing on the fly ?

    Thanks
