  • 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.

  • Encode flv video with no audio with ffmpeg

    15 avril 2012, par David Bengoa

    I'm making an application that needs to convert videos to webm or mp4, it works great with all videos I've tried, but it fails if I use a flv file with no audio channels.

    $ ffmpeg -i 0986229665-339108519108-86498841039-6078455325.flv out.webm

    If I pass the -an option, it works, but I can't do that because then all videos wouldn't have audio.

    Any ideas ?

  • FFmpeg : Read profile level information from mp4

    31 mars 2016, par Martin

    I have a mp4 file and need the profile level of it. FFmpeg says, it has baseline profile, which is what I need, but I need also the level.

    Here is what I get from FFmpeg :

At least one output file must be specified

    Is there any option other than -i I can use to get the level information ?

  • FFmpeg : Remux f4v cutted from stream to mp4

    10 mai 2012, par Penthi

    I have a mp4 file cutted from a H.264/AAC stream with Wowza Media Server.
    After the cutting, the file was forced to mp4 format with the following command :

    ffmpeg -i wowza_output_file -vcodec copy -acodec copy -f mp4 -y wowza_output_file_copy

    From there I renamed it to test_f4v.mp4 and took ffprobe, to take a look at the file :

    Now there is a problem. I need a file, which has the following meta data :

    major_brand     : mp42
    
compatible_brands: isom

    Is there a way to remux the mp4 file to get the major_brand and compatible_brands to the described values with ffmpeg ?
