  • Creating farms of unique websites

    13 avril 2011, par

    MediaSPIP platforms can be installed as a farm, with a single "core" hosted on a dedicated server and used by multiple websites.

  • Les vidéos

    21 avril 2011, par

    Comme les documents de type "audio", Mediaspip affiche dans la mesure du possible les vidéos grâce à la balise html5 .
    Un des inconvénients de cette balise est qu’elle n’est pas reconnue correctement par certains navigateurs (Internet Explorer pour ne pas le nommer) et que chaque navigateur ne gère en natif que certains formats de vidéos.
    Son avantage principal quant à lui est de bénéficier de la prise en charge native de vidéos dans les navigateur et donc de se passer de l’utilisation de Flash et (...)

  • ffmpeg : record 1 hour segment, right on the hour, no/little frame lost [closed]

    2 septembre 2024, par Jean-Michel

    I need to record 24/7 an incoming SRT stream into 1 hour chunks, starting right on the hour.
The start needs to be as close as XX:00:00.000 as possible and little to no frame lost between the recordings.

    


    For now I am using a systemd service with that ExecStart command :

    


    /usr/bin/ffmpeg -fflags +discardcorrupt -i 'srt://:4010?pkt_size=1316&mode=listener' -c copy -map 0:v:0 -map 0:a? -f segment -strftime 1 -segment_time 3600 -reset_timestamps 1 -segment_format ts '/somefolder/recording_%%d%%m%%Y_%%H%%M00.ts'


    


    And using a crontab to restart the service on the hour to insure the next file properly starts at the expected time.

    


    0 * * * * cd /etc/systemd/system && systemctl restart srt_recorder_4010.service


    


    Unfortunately, the restart of the service takes 5 to 10 seconds and we are loosing that duration in the recorded file.
If I'm not using the crontab, I get 1 hour files but I have no control on the start time.

    


    Any suggestion to get something more accurate ?
Could there be a way to combine ffmpeg internal ability to exactly segment 1 hour file but enforce to do it on the hour ?
Or externally, if there was a way to send a "next file" command (api, signal) to a perpetual running ffmpeg to change recording file ?

    


    Thanks

    


  • How do I convert a 3D SBS dual-fisheye image to 3D SBS dual-equirectangular with only open-source tools ? [closed]

    21 octobre 2024, par Ethan T

    Canon has released a new 3D VR lens for their RF mount and I recently rented it to see what it's like to work with. Unfortunately, they charge a subscription fee for their conversion software, which I've also found to be inconveniently limited in real-world use cases. Thus I'm interested in an open-source approach to converting the video captured by this lens using something like ffmpeg.

    


    The video is dual-fisheye and the Canon tool produces dual-equirectangular side-by-side video. I would like to perform this same conversion in ffmpeg or a similarly-powerful open-source tool.

    


    Related questions exist but aren't quite correct. Most dual-fisheye input seems to be used to create 360-degree 2D video, not 3D SBS.
