  • 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.

  • Que fait exactement ce script ?

    18 janvier 2011, par

    Ce script est écrit en bash. Il est donc facilement utilisable sur n’importe quel serveur.

  • Need to install ffmpeg (non static) for my discord bot (node.js) hosted on Heroku

    23 mars 2023, par febkosq8

    I host my Discord Bot on Heroku.

    


    I was using the static ffmpeg buildpack by jonathanong until now.

    


    Due to some issues with Discord-Player package that I use to play music, I will have to use non static version of ffmpeg (See Issue #1639 for more info).

    


    I tried using the aptFile buildpack to install ffmpeg directly.
The build process takes place without any issues. See build log (Pastebin Logs).

    


    But after deploy, I am not able to access ffmpeg.

    


    I keep getting
ffmpeg: error while loading shared libraries: libusb-1.0.so.0: cannot open shared object file: No such file or directory when i try to run ffmpeg thro heroku run command. The bot is also not able to pickup ffmpeg.

    


    ffmpeg fails to run

    


    I am using heroku stack-20 because it was a workaround to the github issue mentioned earlier. The issue exists in stack-22 also.

    


    Need help to figure out a solution for this problem or a way to install non static versions of ffmpeg

    


  • Can't get GCC's -static-libgcc working with DYLIB libraries on Mac OS X

    15 novembre 2024, par Synthetix

    I've installed GCC 4.6.3 into a non-system path on a Mac system and it works fine. However, GCC wants to use code from libgcc for all the binaries I compile, and running otool -L shows that these compiled programs look for libgcc_s.1.dylib in GCC's install path. I can override this by passing -static-libgcc, which just compiles the stuff needed into the binary and that's fine. The problem is this only seems to work with executables, not shared libraries. If I use GCC to compile some third-party lib I want to use in one of my programs as a .dylib, these libraries still look for libgcc_s.1.dylib in the local GCC install path even if I specify -static-libgcc ! Needless to say, this is a problem as there's no guarantee that those libraries will find libgcc when run on some other system.

    



    I tried this with ffmpeg. If I look at config.log, the -static-libgcc is most certainly being used. GCC is just not linking libgcc statically with the resulting dylibs. I even tried the -nostdlib, -nostartfiles and -nodefaultlibs options but they were ignored. Again, I checked config.log and they're definitely there !

    


  • webm local udp streaming using FFMPEG

    1er octobre 2013, par siniv

    I was just started to use ffmpeg recently and stumbled on this streaming problem.
    Scenario : i want to live stream a webcam in local network. Both server and client will be using windows platform.

    Current feasible solution : using ffmpeg simple command line

    to test it quickly i tried to locally stream it (the input doesn't really matter btw in this question).

     On server -> ffmpeg -f dshow -i video="cam1":audio="mic1" -r 30 -g 0 -vcodec h264 -acodec libmp3lame -tune zerolatency -preset ultrafast -f mpegts udp://localhost:6789
    
 On client(the same computer) -> ffplay udp://localhost:6789

    The above works just fine, except for the latency, which i'm getting at about 1-2 second delay.

    Now i want to try to change the encoder to use libvpx (vp8) for video and vorbis for audio (i changed the input to a pre-recorded h264 video, but it really doesn't matter)

     On server 
    
    >ffmpeg -i "suits.mp4" -r 30 -g 0 -vcodec libvpx -acodec vorbis -strict -2 -f webm -f mpegts udp://localhost:6789
    
     On client(the same computer) -> ffplay udp://localhost:6789
    
However this doesn't work... And below are console outputs:

    So does the point to point streaming for ffmpeg just doesn't work for vp8 or am i missing something ? Btw, the end goal is to create a similar video chat based framework and i'll appreciate any suggestion. I'm reading up on webRTC now.
