  • Automated installation script of MediaSPIP

    25 avril 2011, par

    To overcome the difficulties mainly due to the installation of server side software dependencies, an "all-in-one" installation script written in bash was created to facilitate this step on a server with a compatible Linux distribution.
    You must have access to your server via SSH and a root account to use it, which will install the dependencies. Contact your provider if you do not have that.
    The documentation of the use of this installation script is available here.

  • Youtube stream of looping JPG stops randomly

    6 juillet 2021, par timw99

    Hi I'm fairly new at ffmpeg.

    


    I'm currently trying to get a low FPS Youtube stream working over RTMP using a JPG on loop which content gets changed using a NodeJS script periodically. I'm using the following command to stream (variable 3 is my stream key) :

    


    ffmpeg -re -loop 1 -pix_fmt bgr24 -framerate 5 -i img/now.jpg -re -stream_loop -1 -i output.mp3 -f flv -vcodec libx264 -profile:v main -g 60 -keyint_min 30 -b:v 400k -minrate 400k -maxrate 400k -preset ultrafast -tune zerolatency -bufsize 2000k rtmp://a.rtmp.youtube.com/live2/$3


    


    There's multiple things wrong here. The bitrate doesn't actually stay at 400k/s. It just goes to around 200-1000k and then just starts decreasing until the stream stops (usually at around 200-300k bitrate). It still seems like data is being sent (bitrate and current FPS are still updated (though they're very low) and speed goes parabolic. The frame counter itself just stops and Youtube doesn't continue streaming. See example :

    I'm using a Digital Ocean VPS to run it, but the same happens on my own desktop which definitely has the hardware for a simple stream like this. Could it have something to do with me replacing the JPG content while trying to stream it ? I get this error every once in a while, but it seems like it fixes itself judging by the info :

    


    [mjpeg @ 0x562824d1fb40] overread 8
[mjpeg @ 0x562824d1fb40] EOI missing, emulating


    


    I can provide more information if it's needed. Thanks in advance.

  • 2 GB Should Be Enough For Me

    31 août 2010, par Multimedia Mike — General

    My new EeePC 1201PN netbook has 2 GB of RAM. Call me shortsighted but I feel like “that ought to be enough for me”. I’m not trying to claim that it ought to be enough for everyone. I am, however, questioning the utility of swap space for those skilled in the art of computing.



    Technology marches on : This ancient 128 MB RAM module is larger than my digital camera’s battery charger… and I just realized that comparison doesn’t make any sense

    Does anyone else have this issue ? It has gotten to the point where I deliberately disable swap partitions on Linux desktops I’m using ('swapoff -a'), and try not to allocate a swap partition during install time. I’m encountering Linux installers that seem to be making it tougher to do this, essentially pleading with you to create a swap partition– “Seriously, you might need 8 total gigabytes of virtual memory one day.” I’m of the opinion that if 2 GB of physical memory isn’t enough for my normal operation, I might need to re-examine my processes.

    In the course of my normal computer usage (which is definitely not normal by the standard of a normal computer user), swap space is just another way for the software to screw things up behind the scenes. In this case, the mistake is performance-related as the software makes poor decisions about what needs to be kept in RAM.

    And then there are the netbook-oriented Linux distributions that insisted upon setting aside as swap 1/2 gigabyte of the already constrained 4 gigabytes of my Eee PC 701′s on-board flash memory, never offering the choice to opt out of swap space during installation. Earmarking flash memory for swap space is generally regarded as exceptionally poor form. To be fair, I don’t know that SSD has been all that prevalent in netbooks since the very earliest units in the netbook epoch.

    Am I alone in this ? Does anyone else prefer to keep all of their memory physical in this day and age ?
