    Le problème du podcasting est à nouveau un problème révélateur de la normalisation des transports de données sur Internet.
    Deux formats intéressants existent : Celui développé par Apple, très axé sur l’utilisation d’iTunes dont la SPEC est ici ; Le format "Media RSS Module" qui est plus "libre" notamment soutenu par Yahoo et le logiciel Miro ;

    Le format d’Apple n’autorise que les formats suivants dans ses flux : .mp3 audio/mpeg .m4a audio/x-m4a .mp4 (...)

  • How can I make sure trimming in ffmpeg with -c:v copy is accurate

    9 avril 2020, par Angelo

    I looked at many things online and I understand it's better to re-encode if you want precision.

    



    But for instance, I have the following command :

    



    -ss 00:00:09 -i "input.mp4" -c:v copy -c:a copy -vframes 600 "output.mp4


    



    Where 600 is calculated using the video's FPS and duration, in this case 10 seconds from an 60FPS video. Can I expect to get something accurate with this all the time ? I tested many variants but this seems to be doing ok for the couple videos I tested for.. And if not, can I really ever get complete ACCURACY with copying, or must I stick to H264 for instance ?

  • Where to place the fontfile for the FFmpeg Android drawtext-Filter ?

    13 juin 2018, par jpGerhard

    I’m using the precompiled FFmpeg-Android by Bravobit (via gradle : implementation 'nl.bravobit:android-ffmpeg:1.1.5' ; based on WritingMind’s) with the intention of drawing the current timestamp/location onto a .mp4 file. I am completely new to FFmpeg and have started with Android Studio a few months ago.

    Information :

    • IDE : Android Studio
    • OS : OSX 10.13.5

    My problem :

    I don’t know whether the fontfile needs to be in the Application path on my Phone, in the Android Studio directory or just on a location on my MacBook (so it gets compiled when running the application).

    Basic FFmpeg commands (-version, ...) are working, but I can’t seem to figure out where I have to place my fontfile.

    My current command is as follows :

    -i /path/to/video.mp4 -vf drawtext=fontfile=/users/shared/fonts/arial.ttf :text='Hello World' /path/to/output.mp4

    I’ve tried a lot of variations and always received to following errors :

    Fontconfig error : Cannot load default config file
    [Parsed_drawtext_0 @ 0xecbfd420] impossible to init fontconfig
    [AVFilterGraph @ 0xec9cc140] Error initializing filter ’drawtext’ with args ’fontfile=/users/shared/fonts/arial.ttf:text=Hello World’
    Error reinitializing filters !
    Failed to inject frame into filter network : Unknown error occurred
    Error while processing the decoded data for stream #0:0
    Conversion failed !

    Does anyone have a suggestion on how to get this to work ?
