  • 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 (...)

  • How to create a video thumbnail without ffmpeg or HTML5 video canvas ? [duplicate]

    14 mai 2014, par user3631926

    This question already has an answer here :

    I need to create a thumbnail from a video, I have tried the below options but they didn’t work for my case. I am using S3 and CloudFront.

    1. ffmpeg is not supported via my hosting because I am using a shared hosting and I need to upgrade to VPS or dedicated server if I want to use ffmpeg.

    2. I tried taking a screenshot from the video using HTML5 drawImage and toDataURL functions, but it is throwing SecurityError because my video file is located on Amazon CloudFront and my code is hosted somewhere else.

    Is there any other option or a workaround to the second option ? I don’t want to upgrade my server for just the thumbnail issue.

  • Is it advisable to use FFMpeg on my local server for video conversion ?

    7 juin 2019, par Yash Desai

    We are starting a video sharing website where users will be able to upload videos in their native formats. However, since video streaming on the web generally is in the FLV format, we need to convert the videos to FLV.

    Also, the site will be hosted on Amazon EC2 and storage using S3.

    Can i run FFMpeg on amazon EC2 ? Is this the best way to go ? Are there other alternatives to video encoding rather than doing conversion on our own server ? I also came across www.transloadit.com which seems to do the same but they are charging a bomb. Are there cheaper and more intelligent alternatives ?

    We are planning to make this website as one of top 10 biggest niche video streaming websites on the internet.

  • FFMpeg HLS streaming stutters

    18 juin 2022, par Peter Hammi

    I'm using FFmpeg to encode a video to HLS format. The problem is that it seems that on playback of the stream, I'm always missing a half frame, which leads to the problem that the picture visually seems to micro stutter every second for a half frame, so it's very little but still visible.

    


    The actual FFmpeg command put together by my app looks like this :

    


    [Command] /usr/bin/ffmpeg -i "/tmp/VODProcessing/testclip.m4v" -map 0:0 -c:v libx264 -b:v 6291456 -maxrate:v 6606028 -bufsize 25165824 -vf zscale=width=1920:height=1080 -profile:v baseline -level 4.1 -pix_fmt yuv420p -sc_threshold 0 -keyint_min 48 -g 48 -bf 0 -crf 15 -preset medium -r 25 -map_metadata -1 -map_chapters -1 -f hls -hls_time 6 -hls_list_size 0 -hls_segment_filename "/tmp/VODProcessing/output/testclip/v-h264-1080p-avc1.640029/f-%04d.m4s" -hls_fmp4_init_filename "init-v-h264-1080p-avc1.640029.m4s" -hls_segment_type fmp4 -movflags frag_keyframe -hls_flags independent_segments "/tmp/VODProcessing/output/testclip/v-h264-1080p-avc1.640029/master.m3u8"


    


    Is it possible that -keyint_min 48 -g 48 is simply wrong, and I've got dropped frames ?

    


    Thanks in advance
