Les statuts des instances de mutualisation
13 mars 2010, parPour des raisons de compatibilité générale du plugin de gestion de mutualisations avec les fonctions originales de SPIP, les statuts des instances sont les mêmes que pour tout autre objets (articles...), seuls leurs noms dans l’interface change quelque peu.

FFMpeg, rtsp cameras and series of bad framses
21 avril 2022, par Denis GottardelloI have a problem with ffmpeg and rtsp cameras.
As you can see in the screenshot below




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 spidereliteI'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
andlive555
libraries but I need to find their use and API in theodm.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 ?
