  • Récupération d’informations sur le site maître à l’installation d’une instance

    Utilité
    Sur le site principal, une instance de mutualisation est définie par plusieurs choses : Les données dans la table spip_mutus ; Son logo ; Son auteur principal (id_admin dans la table spip_mutus correspondant à un id_auteur de la table spip_auteurs)qui sera le seul à pouvoir créer définitivement l’instance de mutualisation ;
    Il peut donc être tout à fait judicieux de vouloir récupérer certaines de ces informations afin de compléter l’installation d’une instance pour, par exemple : récupérer le (...)

  • video hosting with PHP api or PHP script for social network project

    17 avril 2014, par al404IT

    I have a project for a small social network where user can upload their videos, video should not be longer than 1 or 2 minutes but they need to be private and related to user that uploaded.

    Since uploaded video may be in many different format I have two options :

    • upload video and use ffmpeg to process them, can i find any PHP script that does that ? PROS I have my files on my server and I'm not dependent from third party CONS I guess is a real intensive task and I may need a quite good noting plan since the beginning of this project

    • use a video hosting service that provide API to upload and process video, i actually find vzaar.com that may seems to do what I need. PROS Scalable CONS I rely on third party for my contents

    since the project is a small social network it may be interesting this too opusphp.com, but i never user or read about

    can Vimeo PRO suite my needs ? Other suggestions ?
    In future it may be necessary to add a basic video editing function to trim uploaded video setting starting and ending point

  • FFmpeg Image to Video command consuming 100% CPU

    23 décembre 2023, par Dishan Verma

    I am working on a project where I need to first extract all the frames of videos and after extracting the frames I need to stitch the frames back again showing 1 frame for exactly 1 seconds i.e I need to create a 1 FPS video from extracted frames.

    


    I am successfully able to extract frames of video using ffmpeg without any issues.

    


    But my FFmpeg command which I am using to convert frames to 1 FPS video is consuming 100% CPU, for example a 40 mb video input is consuming 8 GB of CPU. Below is how my FFmpeg command looks like.

    


    final String ffmpegCommandFormat = "%s -framerate 1 -i %s -c:v libx264 -pix_fmt yuv420p -crf 18 -y %s";
final String ffmpegCommand = String.format(ffmpegCommandFormat, FFMPEG_EXEC_PATH, framesPathRegex, pathToStoreProcessedVideo);


    


    I am creating a service which needs to support around 2 GB sized videos and with the current behaiviour it cannot even support 100 MB of video.

    


    Can anyone please help me here to understand why FFmpeg is consuming too high CPU and how can i resolve this issue ?
Is there any alternate/better/fast/efficient command which I can use to created 1 FPS video wither from extracted frames or directly from input video ?

    


    I am new to ffmpeg so not sure what else to explore.
