  • Déploiements possibles

    31 janvier 2010, par

    Deux types de déploiements sont envisageable dépendant de deux aspects : La méthode d’installation envisagée (en standalone ou en ferme) ; Le nombre d’encodages journaliers et la fréquentation envisagés ;
    L’encodage de vidéos est un processus lourd consommant énormément de ressources système (CPU et RAM), il est nécessaire de prendre tout cela en considération. Ce système n’est donc possible que sur un ou plusieurs serveurs dédiés.

  • How to customize the spectrograms generated with ffmpeg or SoX ? [closed]

    6 mai 2024, par Mark I

    I found code to batch generate spectrograms of music files I have with SoX and ffmpeg, and while they work I'd like to customize the spectrograms they generate to make them look "nicer", more like Spek's. Specifically, I want to change the x axis' time format from s to mm:ss, the font, the frequency format, and add some info about the file above the spectrogram. I can't find anything in their documentation, so what parameters would I have to add to the sox or ffmpeg commands to make their output look more like this ?

    


  • FFmpeg, preserve album cover when converting from MP3 to Opus (OGG)

    20 mai 2021, par sampormta

    So basically I'm using FFmpeg Batch AV Converter (which is very good and I recommend) and I'm trying to convert all my music which is stored in FLAC, AAC and MP3 to Opus (OGG).

    


    The problem is that I don't know what should I do so that the album cover is preserved in the conversion. As in, the metadata itself is copied to the Opus file, except the album cover.

    


    Now of course I could add it later with a metadata editor, but it's too much work and it may even be unnecessary if there is a command to do that.

    


    I currently use :

    


    -c:a libopus -b:a 128k -vbr on -compression_level 10 -frame_duration 20 -application audio


    


    Any help will be appreciated.

    


    Thank you !

    


  • ffmpeg images-to-video script anyone ?

    6 juillet 2017, par danja

    I’m wanting to take a bunch of images and make a video slideshow out of them. There’ll be an app for that, right ? Yup, quite a few it seems. The problem is I want the slides synced to a piece of music, and all the apps I’ve seen only allow you to show each slide for a multiple of a whole second. I want them to show for multiples of 1.714285714 seconds to fit with 140 bpm.

    The tools I’ve seen generally seem to have ffmpeg under the hood, so presumably this kind of thing could be done with a script. But ffmpeg has sooo many options...I’m hoping someone will have something close.

    I’ll have up to about 100 slides, the ones that have to show for 3.428571428 secs or whatever I guess I can simply show twice.
