  • Les tâches Cron régulières de la ferme

    1er décembre 2010, par

    La gestion de la ferme passe par l’exécution à intervalle régulier de plusieurs tâches répétitives dites Cron.
    Le super Cron (gestion_mutu_super_cron)
    Cette tâche, planifiée chaque minute, a pour simple effet d’appeler le Cron de l’ensemble des instances de la mutualisation régulièrement. Couplée avec un Cron système sur le site central de la mutualisation, cela permet de simplement générer des visites régulières sur les différents sites et éviter que les tâches des sites peu visités soient trop (...)

  • FFMpeg Logo Different Sepration [closed]

    9 mai 2024, par unkp

    Simple :

    


    1.Want a logo to be only for specific times on a video,

    


    motivation : reduce length of the process if possible.

    


    the code used for logo is this one :

    


    ffmpeg -i output0.mp4 -vf "movie=logo.png [watermark] ; [watermark]scale=220x220 [watermark2] ;[in][watermark2] overlay=main_w-overlay_w-10:main_h-overlay_h-10 [out]" output0logo0done.mp4

    



    


    Would Want like something like this if possible : keep the logo for 1 minute then 4 minutes later keep the logo again for 1 minute.

    



    


    Tried searching about this request, the answers found were related to ->

    


    split the parts like 1,2,3,4,5 only add the logo to odd parts ->

    


    combine them after, this may be too troublesome

  • C# library for audio resampling that has the same abilities as FFmpeg

    21 avril 2013, par Designation

    I have to use a pure C# solution for resampling audio, which can produce me the exact same results as FFmpeg's audio sampling can.

    FFmpeg first builds some kind of polyphase filter bank, and then uses that for the sampling process (sorry for the vague phrasing, but I'm not too familiar with this topic). According to this brief documentation, the initialization can be customized this way :

    AVResampleContext* av_resample_init(
       int     out_rate,
       int     in_rate,
       int     filter_length,
       int     log2_phase_count,
       int     linear,
       double  cutoff  
       )

    The parameters are :

    • out_rate : output sample rate
    • in_rate : input sample rate
    • filter_length : length of each FIR filter in the filterbank relative to the cutoff freq
    • log2_phase_count : log2 of the number of entries in the polyphase filterbank
    • linear : if 1 then the used FIR filter will be linearly interpolated between the 2 closest, if 0 the closest will be used
    • cutoff : cutoff frequency, 1.0 corresponds to half the output sampling rate

    I'd need to use a C# library that is configurable in the same depth. I've been trying to use NAudio (more specifically, its WaveFormatConversionStream class), but there, I could only set the input and output sample rates, so I didn't get the expected results.

    So, is there a C# lib that could resample with the same settings as FFmpeg can ? Or one that has almost all of these settings or similar ones ? Note : I need a C# solution, not a wrapper !
