  • 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" (...)

  • rtmpproto : Pass the ’live’ parameter in the right unit

    3 octobre 2013, par Martin Storsjö
    rtmpproto : Pass the ’live’ parameter in the right unit

    The current magic numbers passed are values in seconds, while the
    
parameter itself should be passed over the wire in milliseconds.
    

    This makes (some/all ?) live streams from Red5 work correctly, that
    
previously returned StreamNotFound even with "-rtmp_live live". After
    
this commit, the default ’any’ also works on these streams.

  • how to optimize x264 for online live education scene？

    21 juillet 2020, par Longshan DU

    I am working on a x264 optimization project for online live education. Often, the teachers are sitting before the camera, and doesn't have big motion, and the background are the same (exception light changes). And is there some papers that I can refer to that can reduce the bit rate or improve the video quality ?

  • Live jpeg sequence image to RTMP fps drop

    6 avril 2021, par m0j1

    I want to encode a sequence of jpg images (captured from my camera in unity) to h264 codec live stream video. I'm using the following command in ffmpeg :

    &#xA;

    -f image2pipe -vcodec mjpeg -r 25 -i  udp://127.0.0.1:6000  -r 25 -preset slow -vcodec libx264 -tune zerolatency -b:v 800k -maxrate 800k -bufsize 400k  -f mpegts udp://127.0.0.1:5701&#xA;

    &#xA;

    On the other side, I playback this live stream using ffplay (ffplay -fflags nobuffer -flags low_delay -framedrop udp ://192.168.189.112:5701) and everything seems to be fine.
    &#xA;After that, I want to use a media server to restream this to other clients so I chose node media server and with the following ffmpeg comment I stream my image sequence to my media server :

    &#xA;

    -f image2pipe -vcodec mjpeg -r 25 -i  udp://127.0.0.1:6000  -r 25 -preset slow -vcodec libx264 -tune zerolatency -b:v 800k -maxrate 800k -bufsize 400k  -f flv rtmp://192.168.189.112/live/STREAM_NAME&#xA;

    &#xA;

    But when I use ffplay to playback this live stream using the following command I get a choppy stream that looks like it is in 5fps :

    &#xA;

    ffplay -fflags nobuffer -flags low_delay -framedroprtmp://192.168.189.112/live/STREAM_NAME&#xA;&#xA; &#xA;

    &#xA;

    I also tried to first record my live stream using node media server and then play it to see if I had received the data right and surprisingly the recorded video is perfect.

    &#xA;I wanted to ask if someone has any tips or experience about this.
