  • Le plugin : Podcasts.

    14 juillet 2010, par

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

  • avcodec/mpeg12dec : Limit maximum A53 CC size

    21 septembre 2020, par Michael Niedermayer
    avcodec/mpeg12dec : Limit maximum A53 CC size

    This is more than 10 times the size of the largest i found. And also alot more
    
than our encoder could handle (our encoder is limited to max 31)
    
Without any limit megabyte+ sized blocks can be reallocated millions of times.
    
Sadly the SCTE-20 spec does not seem to contain any hard limit directly, so this limit here
    
is arbitrary
    

    Fixes : Timeout (25sec -> 152ms)

  • How do hot switch video files in ffmpeg ? [closed]

  • How can I apply complex filters more than once with different parameters while avoiding "too many inputs" errors

    15 mai 2019, par Hugh Walxet

    I’m trying to apply the displace complex filter more than once in a video, at specific intervals with no proportional relationship. In each instance, I want to apply the displace filter with slightly different parameters. If I list it twice in the commands for the complex_filter, I get an error saying I have too many inputs.

    I might as well ask, separately, how I could apply the same filter with the same parameters more than once in a video, without re-iterating the same filter more than once in the command line. Put differently, how do I run a filter as specific times without writing the command several times sequentially, each with a different trigger time ?
