  • Script d’installation automatique de MediaSPIP

    25 avril 2011, par

    Afin de palier aux difficultés d’installation dues principalement aux dépendances logicielles coté serveur, un script d’installation "tout en un" en bash a été créé afin de faciliter cette étape sur un serveur doté d’une distribution Linux compatible.
    Vous devez bénéficier d’un accès SSH à votre serveur et d’un compte "root" afin de l’utiliser, ce qui permettra d’installer les dépendances. Contactez votre hébergeur si vous ne disposez pas de cela.

  • Dash JS Player Cross Browser Compatibility

    21 mai 2015, par JJ The Second

    I am conducting a research for my company streaming service. I found dash.js for adaptive streaming which is a perfect solution along with ffMpeg for transcoding.

    So how this solution works is to create bunch of files served in .mpd format. Now the questions I have :

    1. Do you think this a early stage and I should wait before start using DASH.JS ? Do you think there is a better solution for safe and fast streaming ?

    2. Player options : So far the only player I found was this http://dashif.org/reference/players/javascript/1.0.0/

      I have no idea how compatible it is with browsers and what limits I’ll be facing if I chose it. Is there any other solid solution for this ?

    3. Do you guys think I’m going wrong direction for this ?

    4. What are my server requirements to run these technologies ? I have a 500MBs, 64GB Ram, 24 Core, 2TB beast, does this do the job ?

  • Using ffmpeg to encode web dash and audio drift

    1er octobre 2016, par John Joske

    I’m trying to use ffmpeg to create webm-dash encoded files from a usb web cam. Adapted from this example http://wiki.webmproject.org/adaptive-streaming/instructions-to-do-webm-live-streaming-via-dash

    I have managed to get something nearly works with the following command :

    ffmpeg -f video4linux2 -framerate 30 -s 640x360 -i /dev/video0
    -thread_queue_size 512 -f alsa -ar 44100 -ac 2 -i hw:2 -map 0:0 -pix_fmt yuv420p -c:v libvpx-vp9 -s 640x360 -keyint_min 60 -g 60 -speed 6 -tile-columns 4 -frame-parallel
    1 -threads 8 -static-thresh 0 -max-intra-rate 300 -deadline realtime
    -lag-in-frames 0 -error-resilient 1 -f webm_chunk -header video_360.hdr" -chunk_start_index 1 video_360_%d.chk -map 1:0 -c:a libvorbis -b:a 128k -ar 44100
    -f webm_chunk -copytb 1 -audio_chunk_duration 2000 -header video_171.hdr -chunk_start_index 1 video_171_%d.chk

    However over a period of time the audio chunks slowly get behind the video chunks, can anyone suggest a way to ensure they stay the same.

  • Is it possible to pipe an ffmpeg output with multiple files (HLS or DASH)

    29 août 2020, par New Dev

    I'm using FFmpeg to generate fragmented MP4s in a dash and HLS format.

    


    ffmpeg -i input.mov -f dash -seg_duration 6 -hls_playlist true output.mbd


    


    The above (simplified) command outputs multiple files, in addition to output.mdb (e.g. actual segments, master.m3u8, etc...)

    


    Is there a way to get each produced file into their individual and separate output streams ?

    


    


    Broader context :

    


    I'm trying to build a transcoder in Node.js running in Google Cloud, with the idea being that it writes directly to a Google Storage through a writable stream. I can only create a stream per file, but since the number of files is dynamic, I'm not sure how to obtain a stream from each file.
