    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 (...)

  • android ffmpeg concatenate multiple m4a files

    19 janvier 2017, par margie

    I need help in concatenating audio files in android using ffmpeg

    My source of audio files is from recording result (container .m4a, encoder aac).
    When I concat them using ffmpeg, the result file length(duration) is only of the 1st file.

    ie. FileA length = 1:00, FileB length = 0:14. Expected FileResult length = 1:14, but actual result is 1:00).

    I also tried the command I used in desktop ffmpeg and it give the same result.

    This is my command :

     [-i, 
    
concat:storage/emulated/0/Music/Recordings/REC_20170119_162023.m4a|/storage/emulated/0/Music/Recordings/REC_20170119_162042.m4a, 
    
-c, 
    
copy, 
    
/storage/emulated/0/Music/Recordings/REC_20170119_162047.m4a]

    and the ffmpeg result is :

  • VLC - Could someone assist me into improving latency in streaming to web based app ?

    19 janvier 2017, par zyeek

    I have been looking for solutions in which I can stream an IP camera’s stream to HTML 5. Currently as is it doesn’t support RTSP so easily.

    I am trying to be able to view the camera’s stream as live as possible. I was hoping someone could help me achieve that. I have been playing with it to get something workable, but at the moment I get a 5s delay stream. It is smooth, but wish to get it hopefully within <1-2s delay if possible.

    My current setup goes from taking my IP camera’s stream in RTSP and converting it to a webm and streaming it to a url, which then I plan on using that to put else where in a web app.

    What I would like to achieve

    Use a protocol that has low latency with audio was well. Webm was used as test, but I can’t seem to get other commands to get the proper stream to be going.

    I would like to use DASH, but from reading FFMPEG currently doesn’t support it. I was thinking maybe RTMP would be good enough for now, being both low latency and HTTP 5 compatible. I am just unable to figure out how to get FFMPEG to transcode the RTSP to RTMP.

    SETUP :

    I am using ffserver and ffmpeg. Overall scope : trying to pull IP camera stream and put it on a web app.

    Framework I am use is Meteor JS. So, I am trying to few plugins or outside complex setups as I want to be able to deploy this Meteor app on mobile devices as well. So, I want to stay within the boundaries of what HTML 5 can support.

    My current ffserver setup is ffserver.conf (this was taking from bunch of different place :

    HTTPPort 8090                      # Port to bind the server to
    
HTTPBindAddress 0.0.0.0
    
MaxHTTPConnections 2000
    
MaxClients 1000
    
MaxBandwidth 10000             # Maximum bandwidth per client
    
                               # set this high enough to exceed stream bitrate
