  • Creating farms of unique websites

    13 avril 2011, par

    MediaSPIP platforms can be installed as a farm, with a single "core" hosted on a dedicated server and used by multiple websites.
    This allows (among other things) : implementation costs to be shared between several different projects / individuals rapid deployment of multiple unique sites creation of groups of like-minded sites, making it possible to browse media in a more controlled and selective environment than the major "open" (...)

  • Jerky Video from Jpgs encoded with ffmpeg [closed]

    16 février 2012, par Glstunna

    I have a bunch of jpg snapshots taken from a 3d program at perfect time frames.
    But when I have the videos compiled/encoded into a video by ffmpeg, I notice an annoying jerkiness. The jerkiness is not that pronounced, but enough to be annoying, especially during slow camera pans.

    This is what I use :

    "ffmpeg-lgpl.exe" -y  -r 29.97 -i "C:\vidsnaps\vid_%d.jpg" -b 8000k "C:\Users\peki.ICE\Documents\macbattle.mpg"

    I chose mpg (mpeg1video) because that is the format readily available in all end-user systems like XP without downloading extra codecs. The video images are guaranteed to match that framerate 29.97 as the camera in the 3d program pretty much waits for each frame to be dumped to file before moving to the next one.

    What other fancy ffmpeg flags do I have to set for this thing to stop being jerky.

    EDIT : see video example here and notice the light jerk/stuttering.

  • Streaming RTMP to JANUS-Gateway only showing bitrate but no video

    14 avril 2021, par Ilyas OUMNIH

    I'm currently using the streaming plugin as follows
Fancy artchitecture here

    



    OBS--------RTMP--------->NGINX-Server------FFMPEG(input RTMP output RTP)--------->JANUS---------webrtc-------->Client

    



    When using the ffmpeg command (bellow), on the Janus streaming interface, we only see the bitrate that corresponds to that of the ffmpeg output in the console but we don't see any video.

    



    ffmpeg -i rtmp://localhost/live/test -an -c:v copy -flags global_header -bsf dump_extra -f rtp rtp://localhost:8004 


    



    


    (using "-c:v copy" so that no encoding is used and hence reducing the
 latency)

    


    



    The video shows fine if I use "-c:v libx264", the only issue is that it is CPU intensive and adds latency.

    



    Previously I had tried using RTSP as input for FFMPEG and in this case the video show fine with almost no latency even though I use "-c:v copy".

    



    So I don't realy get why for RTSP the copy works fine, but for RTMP I have to use the libx264 codec. If anyone has an idea about this I am all ears :)

    


  • ffmpeg streaming to youtube becomes slow and starts buffering

    13 août 2022, par Syphax

    I'm using FFmpeg to broadcast to YouTube via rtmp.

    


    I'm using a cloud computing instance.

    


    Whether I put an HD video or low quality to broadcast, at the beginning it says that all is good and connection is Excellent, but after about 3 hours it becomes slow and starts to cut.

    


    I don't understand why this is happening, and if you know guys any tips to fix that.
Thanks...
