  • 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.

  • FFMPEG recording in ASP.NET Core mvc application

    19 avril 2020, par Timber

    I'm using ASP.NET Core and ffmpeg to record a live video stream. When the page receives a get request, the stream should begin recording and saving to a folder using ffmpeg. I want to make it so that when visiting the stop endpoint, the ffmpeg process is closed cleanly.

    



    Unfortunately I'm unable to send a 'q' to stdin after leaving the Get method. Using taskkill requires the use of /F making the ffmpeg process (which is not a window) force quit and not save the video properly, resulting in a corrupt file.

    



    I tried using Process.Kill() but that results in a corrupt file as well. Also, I tried Process.CloseMainWindow() which worked, but only when the process is started as a window, and I'm unable to start the process as a window in the server I'm using.

    



    I've include the code I have so far below, so hopefully someone could lead me in the right path.
