  • Le plugin : Gestion de la mutualisation

    2 mars 2010, par

    Le plugin de Gestion de mutualisation permet de gérer les différents canaux de mediaspip depuis un site maître. Il a pour but de fournir une solution pure SPIP afin de remplacer cette ancienne solution.
    Installation basique
    On installe les fichiers de SPIP sur le serveur.
    On ajoute ensuite le plugin "mutualisation" à la racine du site comme décrit ici.
    On customise le fichier mes_options.php central comme on le souhaite. Voilà pour l’exemple celui de la plateforme mediaspip.net :

  • How to configure B-frames (no leading P-frames) in x265

    5 mars 2020, par Alearner

    I have been rolling around with my studies in x265 encoder for days. Guess now I get better click on how x265 works than my first day. I usually use the HEVC reference software, and so think I am too comfortable with its environment because now I cannot figure out how to set the x265 encoder to code only I- and B-frames as if the Random Access or Low-Delay-B configurations in HEVC.

    I set my encoder with this CLI option to encode 500 frames of BasketballPass sequence :

    --input BasketballPass_416x240_50.yuv --input-res 416x240 --fps 50 --frames 500 --rd 4 --no-lossless --csv-log-level 2 --csv infoQP37.csv --no-wpp --psnr --ssim -b 16 --b-pyramid 0 --b-adapt 0 --keyint 48

    Instead of get only I- and B-frames encoded, P-frames also show up in my log file :

    Enc.order Type      POC
    
0         I-SLICE   0
    
**1       P-SLICE   17**

35        i-SLICE   48
    
......

    My question is, can the x265 configure encoder as in RA or LDB of HEVC ? If yes, I’d appreciate any guidance to do it. Or How can we encode only I- and B-frame only (without P-frame) in x265 ?

  • Difference between MPEG-TS and RTP for H.264 (.mp4) video streaming ?

    6 avril 2022, par Candy

    So I am trying to stream a H.264 (.mp4) video over ETHERNET using the ffmpeg tool. I have read a little about transport of H.264 video over ethernet and have learnt that there are two methods ; mpeg-ts and RTP (both over UDP). I have been able to stream the .mp4 video through both methods in ffmpeg (over localhost) and haven't noticed any difference in quality or latency as such. What is the difference in concept and efficiency between the two protocols for transportation of video ? Or am I mixing two different concepts ? Any help is appreciated !

  • gathering images and streaming to user as video from memory (ffmpeg)

    29 novembre 2013, par Abdul Ali

    apologies if this has been asked before but cannot find something for a beginner.

    purpose it to fetch ongoing stream of images and keep them combining into a video. That video should be sent to users from within the memory and not saved physically to a disk (the video should keep on streaming till the images are coming).

    have read somethings about FFMPED and pipes . am new to both these concepts :) (furtherfmore , am also new to the concept of streaming).

    kindly assist if this can be achieved. if so, then please provide some guideline and which language out of PHP & C# may be more suitable (also whether it is achieveable in linux and windows).

    regards,
