  • Possibilité de déploiement en ferme

    12 avril 2011, par

    MediaSPIP peut être installé comme une ferme, avec un seul "noyau" hébergé sur un serveur dédié et utilisé par une multitude de sites différents.
    Cela permet, par exemple : de pouvoir partager les frais de mise en œuvre entre plusieurs projets / individus ; de pouvoir déployer rapidement une multitude de sites uniques ; d’éviter d’avoir à mettre l’ensemble des créations dans un fourre-tout numérique comme c’est le cas pour les grandes plate-formes tout public disséminées sur le (...)

  • Using ffmpeg with Flash Media Server and HDS

    20 avril 2012, par Jonathan

    I want to use ffmpeg to encode and publish a live stream to Flash Media Server. In order to support iOS devices, I need to implement HTTP Live Streaming as well. The video needs to be in H.264 format and the audio should be AAC. I don't have much experience working with ffmpeg, and I'm having a hard time getting this to work. This is the command that I've tried (and some variations as well) :

    ffmpeg.exe -threads 15 -f dshow -i video="USB2.0 UVC WebCam":audio="Microphone (Realtek High Defini" \
    
      -map_channel 0.1.1 -r 24 -acodec libvo_aacenc -ar 22050 -ab 128k -vcodec libx264 \
    
      -s vga -vb 100k -f flv "rtmp:///livepkgr/livestream1?adbe-live-event=liveevent" \
    
      -r 24 -acodec libvo_aacenc -ar 22050 -ab 128k -vcodec libx264 -s qvga -vb 200k \
    
      -f flv "rtmp:///livepkgr/livestream2?adbe-live-event=liveevent" \
    
      -r 24 -acodec libvo_aacenc -ar 22050 -ab 128k -vcodec libx264 -s vga -vb 350k 
    
      -f flv "rtmp:///livepkgr/livestream3?adbe-live-event=liveevent"

    When I run this, it appears to connect to FMS, but then I get a lot of error messages about dropped frames - I'm not sure if ANY frames get encoded successfully. My CPU usage is very high as well. I get a 404 error from FMS when I enter the URL of the *.m3u8 file for one of the individual streams (the main livestream.m3u8 file is accessible though). I have also tried outputting to a file instead of FMS, with no success. All I get is some very garbled sound and no video.

    Any suggestions for what options/commands I should use to get this working ? Is anyone using ffmpeg with FMS to do HTTP Dynamic Streaming / HLS with MP4 video ? I've been struggling to get HDS/HLS working for some time now, and any help would be much appreciated ! It shouldn't make a difference, but I'm using FMS on Amazon EC2 with their AMI image.

    Thanks !

  • FFMPEG and HTTPS

    14 juin 2012, par Joel

    ffmpeg lists http as a protocol when I ask : ffmpeg -protocols

    Does this also mean support for a https url ? Do I need to encode this url somehow for the command line. I get "No such file or directory", but with http urls (at least some) it does work.

    A url (created for a Amazon S3 bucket) similar to this one does not seem to work :
    https://mycompany-video-test.s3.amazonaws.com/client/btr/video/xyz0011-x403-snap-n-go-ex/1/video/baby-laugh-ripping-paper.mp4?AWSAccessKeyId=AVIAZL9J6SIRPAA&Expires=1323709667&Signature=pTvS9F2do2t8%3D

    I suspect the format of the url is problematic, I've also tried enclosing in quotes... Yes, this URL does not currently work as it has expired, but even while its valid, its a problem.

    In short :
    1) Should https work ?
    2) Do I need to format the url somehow ?
