  • 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.

    La gestion de la ferme passe par l’exécution à intervalle régulier de plusieurs tâches répétitives dites Cron.

  • Rails 4.2.8 Using Paperclip With Resque

    27 mars 2017, par AntonioMarquis

    My application uploads training videos to a S3 bucket. I need the transcoding videos to be processed in the background so they don’t tie up the application. I want to use Resque on my dev machine and Heroku. But my jobs continue to fail.

  • Normalize samples with ffmpeg

    5 avril 2017, par Steva

    I am writing application for music analysis. I wrote resampling module relying on ffmpeg. Currently, I have AV_SAMPLE_FMT_S16 but later I have converting to float, which can be time consuming.

    Because I need samples to be in some reasonable interval I need to do some kind of normalization, for AV_SAMPLE_FMT_FLT samples.

    So, how I can normalize samples which I get when I select AV_SAMPLE_FMT_FLT. Ideal interval would be -n to n, where n is greater than equal of 1.f

  • vlc runtime frame manipulation

    9 avril 2017, par RonTLV

    Regarding VLC, where is the best place to hook on each video frame ?

    I’ve cloned VLC and compiled successfully, and I understand that VLC has modules that it loads. I also noticed that VLC downloads ffmpeg and compile it.

    Should I write a VLC Module or ffmpeg filter ?

    Help is appreciated
