  • 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 (...)

  • Installation en mode ferme

    4 février 2011, par

    Le mode ferme permet d’héberger plusieurs sites de type MediaSPIP en n’installant qu’une seule fois son noyau fonctionnel.
    C’est la méthode que nous utilisons sur cette même plateforme.
    L’utilisation en mode ferme nécessite de connaïtre un peu le mécanisme de SPIP contrairement à la version standalone qui ne nécessite pas réellement de connaissances spécifique puisque l’espace privé habituel de SPIP n’est plus utilisé.
    Dans un premier temps, vous devez avoir installé les mêmes fichiers que l’installation (...)

  • How to optimize the FFMPEG h264/aac conversion while generating HLS segments too

    26 septembre 2014, par Arjun Thakur

    I am generating HLS segments using FFMPEG. Here is the command that I am using :

    ffmpeg -i "rtmp ://localhost/oflaDemo/33/hlsopt3 live=1" -y -c:v libx264 -b:v 1000k -vprofile baseline -preset medium -x264opts level=41 -threads 4 -s 480x360 -map 0:v -c:a libfaac -b:a 160000 -ac 1 -hls_time 3 -hls_list_size 3 -hls_wrap 10 -start_number 1 hlsopt3.m3u8

    I am working on Ubuntu 12.04 and using RED5 1.0.2 as my streaming server and I want to stream videos on android and ios devices. But the playback on devices is very jerky, they do not play video smoothly. Also my server’s CPU utilization goes to more than 100%.

    After so much research I have found that the CPU utilization is due to the H264/mpeg-4 aac conversion, But without doing conversion it wont play on Ios and android devices.

    So please suggest me any solution. How I can play it smoothly on mobile devices and also save the CPU utilization.

    Please help me I have almost waisted 10 days on this.

    Any help would be really appreciated.

  • Encode h264 automatically on nginx server

    18 février 2017, par Thinh Pham

    I have installed and configured my own streaming server using Nginx with rtmp module base on this tutorial https://www.vultr.com/docs/setup-nginx-on-ubuntu-to-stream-live-hls-video. I only use live application and record stream into flv file. And now I want to encode any new flv files in my VOD directory automatically to play it on my website. Is it possible to config it in my nginx.conf ? I have tried set record_suffix .mp4; in order to play it without encode but failed.
    Additional, exec ffmpeg -i is not work for me when I want to restream into mobile application.
