  • 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 (...)

  • Media conversion on AWS

    27 juin 2022, par Gurmeet Singh

    I have an API written in nodeJS (/api/uploadS3) which is a PUT request and accepts a video file and a URL (AWS s3 URL in this case). Once called its task is to upload the file on the s3 URL.

    


    Now, users are uploading files to this node API in different formats (thanks to the different browsers recording videos in different formats) and I want to convert all these videos to mp4 and then store them in s3.

    


    I wanted to know what is the best approach to do this ?

    


    I have 2 solutions till now

    


    1. Convert on node server using ffmpeg -

    


    The issue with this is that ffmpeg can only execute a single operation at a time. And since I have only one server I will have to implement a queue for multiple requests which can lead to longer waiting times for users who are at the end of the queue. Apart from that, I am worried that during any ongoing video conversion if my node's traffic handling capability will be affected.

    


    Can someone help me understand what will be the effect of other requests coming to my server while video conversion is going on ? How will it impact the RAM, CPU usage and speed of processing other requests ?

    


    2. Using AWS lambda function -

    


    To avoid load on my node server I was thinking of using an AWS lambda server where my node API will upload the file to S3 in the format provided by the user. Once, done s3 will trigger a lambda function which can then take that s3 file and convert it into .mp4 using ffmpeg or AWS MediaConvert and once done it uploads the mp4 file to a new s3 path. Now I don't want the output path to be any s3 path but the path that was received by the node API in the first place.

    


    Moreover, I want the user to wait while all this happens as I have to enable other UI features based on the success or error of this upload.

    


    The query here is that, is it possible to do this using just a single API like /api/uploadS3 which —> uploads to s3 —> triggers lambda —> converts file —> uploads the mp4 version —> returns success or error.

    


    Currently, if I upload to s3 the request ends then and there. So is there a way to defer the API response until and unless all the operations have been completed ?

    


    Also, how will the lambda function access the path of the output s3 bucket which was passed to the node API ?

    


    Any other better approach will be welcomed.

    


    PS - the s3 path received by the node API is different for each user.

    


  • how to display raw ID3D11Texture2D using Direct3D 11 ? [closed]

    4 novembre 2024, par SkillfulElectro

    I’m working on a video decoding project using Ffmpeg and Direct3D 11, where I obtain frames in the format ID3D11Texture2D. My goal is to display these frames directly without transferring data back to the CPU, in order to minimize overhead.

    


    I’ve decided to use Direct3D 11 for rendering, but I’m unsure of the best approach to efficiently display the ID3D11Texture2D textures.

    


    Could someone provide guidance, relevant keywords, or example code on how to render these textures directly to the screen ?

    


    Environment : Ffmpeg, Direct3D 11

    


    What I’ve tried :

    


      

    • I’ve researched methods for rendering textures in Direct3D but haven’t found a clear, CPU-efficient approach.

    Any advice or code samples ?

    


  • Combining a movie file with a text file

    12 décembre 2012, par Hugo

    Current Status : I have a movie I recorded on a microscopy and a .txt file with two columns : time and temperature. This file is synchronous with the video.
    I would like to 'edit' the video so there is a text box with the temperature that would update as the movie plays.

    My approach, for the moment, is to use ffmpeg. I managed to draw some text and it seems all is working as intended.

    The problem is : I can't find any reference on how to update that text dynamically. I am using some Python to read the file and launch ffmpeg with subprocess.

    I would like to ask if anyone knows some workaround for this. Maybe some other approach.
