  • 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.

  • Convert FLV video with alpha channel to PNGs with transparency

    8 octobre 2012, par AZAR

    I have some FLV videos with alpha channels, and I want to convert each of them to PNG images using ffmpeg but keep the transparency.

    So far, I've tried this :

    ffmpeg -i input.flv -an -y %d.png

    But this outputs the PNG files with black background.

    Is there any way to do this ?

    Alternate acceptable solution : If I can output the images and give the alpha channel a certain color of my choice. I can then remove it later via imagemagick and convert that color to transparency.

  • Which FFmpeg codec should be used for video streams with single byte pixel format ?

    2 décembre 2011, par Gearoid Murphy

    I've got a black and white video stream coming off a Firewire astronomy camera, I'd like to use FFmpeg to compress the video stream but it will not accept single byte pixel formats for the MPEG1VIDEO codecs. I've been trying random codecs for the last hour without much success, could anyone give me some sage advise on how to achieve my goal ? :) thx

  • How can I use the blackframe filter in ffmpeg to only encode images above a certain threshold ?

    8 août 2012, par andyroo

    I am using ffmpeg to make timelapse movies from still images.

    I see that I can use the blackframe filter to get a list of dark frames in a video, but I would like to skip encoding those frames all together.

    Is there a way that I can use the blackframe filter to avoid encoding frames below the blackframe threshold ? Ideally I would be able to do this on a Win7 machine using batch/powershell/python.

    Using another open source program to remove/delete black frames first would be acceptable too.
