  • 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.

  • How to make multi-stage Docker image but avoid shared libraries conflict ?

    26 mai 2022, par Politechniczny

    I need to make a Docker image that contains the following tools :

    


      

    • janus-pp-rec - video processor from Janus WebRTC

      • 


    • ffmpeg and ffprobe

      • 


    • Java 11 JDK

      • 


    


    So I tried to make multi-stage Docker image :

    


    FROM swmansion/janus-gateway:latest as janus
FROM jrottenberg/ffmpeg:latest as ffmpeg
FROM eclipse-temurin:11 as java

COPY --from=janus /usr /usr
COPY --from=ffmpeg /usr /usr


    


    but still some files were missing so I copied the whole containers :

    


    FROM swmansion/janus-gateway:latest as janus
FROM jrottenberg/ffmpeg:latest as ffmpeg
FROM eclipse-temurin:11 as java

COPY --from=janus / /
COPY --from=ffmpeg / /


    


    but still nor janus-pp-rec, neither ffmpeg is working because I get errors :

    


    $ docker container exec videoprocessing janus-pp-rec

janus-pp-rec: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.28' not found (required by /usr/lib/x86_64-linux-gnu/libglib-2.0.so.0)
janus-pp-rec: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.28' not found (required by /usr/lib/x86_64-linux-gnu/libavutil.so.56)
janus-pp-rec: /lib/x86_64-linux-gnu/libm.so.6: version `GLIBC_2.29' not found (required by /usr/lib/x86_64-linux-gnu/libavutil.so.56)
...
janus-pp-rec: /usr/lib/x86_64-linux-gnu/libstdc++.so.6: version `GLIBCXX_3.4.25' not found (required by /usr/lib/x86_64-linux-gnu/libopenmpt.so.0)
...

$ docker container exec videoprocessing ffmpeg

ffmpeg: error while loading shared libraries: libavdevice.so.58: cannot open shared object file: No such file or directory


    


    Any ideas how to make these tools work in one container ?

    


  • Why RTP doesn't support multiple streams to one port but RTSP does ?

    30 avril 2022, par zenno2

    I use ffmpeg for streaming a video using RTP protocol.
Why I can't send multiple streams to one RTP port, but RTSP that uses RTP can ?
I started a RTSP server that listens 8554 TCP port and 8000/8001 RTP/RTCP. It easily can receive both video and audio streams to one port 8000, I've checked it with wireshark. But when I try to do the same with pure RTP using ffmpeg, it prints me an error

    


    Only one stream supported in the RTP muxer


    


    And if I want to stream a video with sound, I have to split them into two streams and send to different RTP ports. Or maybe I can somehow make it receive multiple streams to one port via RTP ?

    


    Could you explain me, why it happens ?
