  • 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 (...)

  • nginx-rtmp + ffmpeg move mp4's moov to head on the fly

    14 février 2017, par eddie.xie

    I have the following use case :

    1) Alice publish stream to the nginx-rtmp server

    2) The server convert the stream to mp4 (default is flv if I understand correctly, and a codec transformation is needed)

    3) Bob should be able to do range request to that mp4 file while Alice is still publishing

    However it seems ffmpeg command for converting a flv to mp4 can only be done when the mp4 file is fully generated, and then ffmpeg will do second pass and move "moov" to its new file’s head

    Our use case is to allow Bob use range request to retrive the mp4 file while Alice is still publishing (i.e. watch Alice’s video as soon as possible) from time 0 (i.e. from the second Alice started publishing). Thus with mp4’s moov at its head, it’s simple to do range requests and implement the functionality. Raw RTMP doesn’t seem to solve our problem, since we can’t let Bob watch from time 0 of Alice’s recording.

    The question is :
    1) Is it possible to do it while the flv is not fully generated yet ?
    2) Any other idea how shall we use nginx-rtmp/ffmpeg to achieve the functionality we desire ?

    Thanks a bunch

  • C# streaming drone video

    13 mars 2020, par jasonmacintosh

    I am currently a student and I have a project which require using the drone and the livestream from its camera

    I managed to find a control program http://www.winardrone.com which can control my ar drone 2.0 , but the problem is that the program doesn’t support my drone’s camera live stream method(TCP)due to the fact that the program is more compatible to the ar drone 1.0(older version drone) which uses(UDP)

    so I have encountered a problem of putting the video stream into my program
    ,there are a really simple solution of using ffmpeg player with cmd command "ffplay tcp ://192.168.1.1:5555", but it does mean that my program have to run in multiple windows and I won’t be able to save my frames with my program to do analyzation

    so could anyone tell me how to Stream my TCP video in my visual studio C# program and capture frames at the same time ?
    just like the program in this video

    I wish to get the video image in a program instead of opening a new window

    And sorry for my bad grammar, thanks for your reply
