  • 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.

    ./configure --prefix=/home/jjh/software/ffmpeg --enable-shared

  • FFMpeg, rtsp cameras and series of bad framses

    21 avril 2022, par Denis Gottardello

    I have a problem with ffmpeg and rtsp cameras.
As you can see in the screenshot below

    


    enter image description here

    


    sometimes a serie of damaged frames come.
It is not a problem related to camera. The date and time is unreadable and the problem happens with different vendors of camera, with differen pcs and in different places.With the official software the live is perfect.
I'm trying with the lates ffmpeg source (5.0.1) in a Debian 11 machine.
I'm particolar intertested in this problem because I have written a software based on ffpmeg library and I have the same problem (using ffmpeg as library), in bouth Windows and Linux.

    


    This is the command line to record

    


    

    

    ./ffmpeg -i rtsp://192.168.1.11:554/onvif1  a.avi

    


    


    



    What can I do to resolve ?

    


  • ONVIF Device Manager API and Decoder

    10 juillet 2023, par spiderelite

    I'm working on the source code of the onvif device manager software and I want to find the Api and decoder it uses.

    


    I first separated the odm.player part of the code into another solution and built it separately. the separated part contains these parts from the source code (in order of execution) :

    


    utils.linq
utils.diagnostics
utils.common
odm.player.lib
odm.player.media
live555
odm.player.net
utils.xml
utils.bootstrapping
odm.player.host


    


    Im tring to find the decoder and Api it uses(in the above parts) to decode the media. i need to find the specific part of the program to contain some information from a decoder.

    


    I know the source code is using ffmpeg and live555 libraries but I need to find their use and API in the odm.player part.

    


    I checked odm.player.host because it is the last project and depends on previous ones, but didn't find anything.

    


    what should i do next ? is there any official documentation of the API ? is there any important keyword related to ffmpeg that can I search it in the code ?
