  • 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.

  • rtmp : Allocate the prev_pkt arrays dynamically

    11 octobre 2013, par Martin Storsjö
    rtmp : Allocate the prev_pkt arrays dynamically

    Normally, all channel ids are between 0 and 10, while they in
    
uncommon cases can have values up to 64k.
    

    This avoids allocating two arrays for up to 64k entries (at a total
    
of over 6 MB in size) each when most of them aren’t used at all.

  • How do you set up carrierwave-video with ffmpeg ?

    24 septembre 2013, par Maleckai

    This has been doing my head in for the past 2 days, and I just cannot seem to get it working.

    I am building a simple Rails app with the sole purpose of uploading & processing images and videos. I'm working on Ubuntu Linux.

    Here's the relevant gems in my Gemfile :

    gem &#39;delayed_job_active_record&#39;
    
gem &#39;carrierwave&#39;
    
gem &#39;carrierwave-video&#39;
    
gem &#39;carrierwave_backgrounder&#39;
    
gem &#39;mini_magick&#39;
    
gem &#39;streamio-ffmpeg&#39;

    At first I was having problems with ffmpeg complaining about certain arguments (I determined this by taking the command the rails app attempted to run when it was to convert a video, and running it manually outside rails), which I discovered was because the version of ffmpeg I was using was 'too new'. So I downgraded to 1.2.1, which is what streamio-ffmpeg says is the only version of ffmpeg they're tested against.

    After that, I could run the command manually, fine. But whenever I tried to convert through the app, I'd get the error :

    Failed to transcode with FFmpeg. Check ffmpeg install and verify video is not corrupt or cut short. Original error: nil is not a symbol

    I did a bit of Googling on the error, and only came up with one relevant result, but nothing in there has helped my situation.

    I'm at a total loss at this point, and am not sure where I can go from here. I assume many of people have tried this before, so I'm hoping someone can guide me on the exact steps they took to get carrierwave-video & ffmpeg working together.

  • Defining moment of the audio attenuation through ffmpeg

    23 août 2016, par riki-tik

    There are audio tracks of different lengths in m4a format. And there’s ffmpeg library for working with the media. Many of the tracks have the effect of "decay" in the end, and it is necessary to determine at what point it occurs (determined once and the value entered in the database along with other information about the track). Those. we must somehow determine that the track begins to fade, and its volume reached 30% compared to the total volume of the song. Is it possible to solve by means of ffmpeg, and if so, how ?
