  • 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 (...)

    We don’t claim to be the only ones doing what we do ... and especially not to assert claims to be the best either ... What we do, we just try to do it well and getting better ...
    The following list represents softwares that tend to be more or less as MediaSPIP or that MediaSPIP tries more or less to do the same, whatever ...
    We don’t know them, we didn’t try them, but you can take a peek.

  • RTMP video streaming client without showing the video just need extensive log

    6 août 2016, par Amir

    I set up an RTMP video streaming server in a cloud environment for research purposes. On another VM in the cloud, I want to use a client to do some experiments. I have tried some different video player like VLC and FFplay but they are keep playing the video in the shell. As it is in the command line environment and to make sure my experiments are not biased with human errors, I need an RTMP video streaming client that just receives the stream as if it wanted to play it and log everything, for instance, if the playback stops due to buffering, average buffer size, etc.

    Thanks

  • How to extract video clip from larger video based on specific time and duration

    26 juillet 2022, par user19019404

    I have video clips that get created. Each video is recorded for 5 minutes and starts at a time e.g. 10:01:20 to 10:06:19 then the next video from 10:06:20 etc. These videos are recorded at a specific frame rate, be it 5 frames or 30 frames (its dependent on the platform making the recording). The net result is NOT a 5 minute video clip but might be a 2 minute video clip (where everyone moves very quickly in the view as a result of the frame rates). I cannot restrict a 1 to 1 recording as these are generated by external systems.

    


    I need to extract specific portions out of the video. For example I need to extract from 10:03:10 to 10:03:35 (25 seconds). This would equate to 10 seconds into the video up to 14 seconds into the video, in those 4 seconds of video, 25 real world seconds are displayed.

    


    My question is do you have any guidance as to how I can calculate that each second of recording actually means 10 or 12 seconds in real life, therefore go to this frame and record to this frame for example.

    


    I have been looking at cv2.CAP_PROP_FPS to get the video frame rates, CAP_PROP_POS_MSEC and CAP_PROP_FRAME_COUNT and believe the answer might lie there, but not sure.

    


    The thinking being if I work out the frame rate of the video, the total frames then I can divide the one by the other to get to how many frames make up real world seconds (this is where I fail). This way I can run from frame to frame as a result.

    


    Thank you

    


  • How can I change the fps of video without restarting the video stream, which is being played by ffmpeg command ?

    7 juin 2018, par Mehta Naisargi Rajeshbhai

    I am playing the video (.mp4) in VLC by this below command in terminal :

    ffmpeg -i input_file.mp4 -crf 18 -c:a copy -r 60 http://localhost:1234/feed1.ffm

    Currently it is 60 fps.

    Now I want to change the fps during the playback of video file, so is it possible to change the fps during runtime without restarting/breaking the video using FFmpeg ? And if it is possible then please guide me.
