La sauvegarde automatique de canaux SPIP
1er avril 2010, parDans le cadre de la mise en place d’une plateforme ouverte, il est important pour les hébergeurs de pouvoir disposer de sauvegardes assez régulières pour parer à tout problème éventuel.
Pour réaliser cette tâche on se base sur deux plugins SPIP : Saveauto qui permet une sauvegarde régulière de la base de donnée sous la forme d’un dump mysql (utilisable dans phpmyadmin) mes_fichiers_2 qui permet de réaliser une archive au format zip des données importantes du site (les documents, les éléments (...) -
Publier sur MédiaSpip

The final lib was created successfully, no error message in log file,
but when I import the lib to my Xcode Project,
the linker give me tons of errors(missing symbols like :
Undefined symbol: _pjsua_vid_codec_set_priority).
I found thepjsua_vid.ois very small(200Bytes) compare to my pjsip+openh264 build file(was 47KB), perhaps this is the reason cause the link error.

Here is my build log :

Cannot use Mobile FFmpeg and LibVLCSharp together in Xamarin.Forms project
26 février 2021, par Travis PI am adding video stream capture functionality to a Xamarin Forms project. I am trying to use VLC's LibVLCSharp.Forms (https://github.com/videolan/libvlcsharp) package and the Mobile ffmpeg Xamarin wrapper package, Laerdal.Xamarin.FFmpeg.* (https://github.com/Laerdal/Laerdal.Xamarin.FFmpeg.iOS). However, the internal ffmpeg library from VLC is conflicting with the ffmpeg wrapper and is built with different flags which exclude functionality that I need.


For native development, it looks like you can configure a preferred library with the
OTHER_LDFLAGSflag in thePods-<your app="app">.debug.xcconfig</your>file but I don't see where to do that with Xamarin.Forms.
Source : https://github.com/tanersener/mobile-ffmpeg/wiki/Using-Multiple-FFmpeg-Implementations-In-The-Same-iOS-Application

How can I configure Xamarin iOS builds to prefer the mobile ffmpeg library over the VLC ffmpeg library ? If I am able to use the mobile ffmpeg library, will it cause issues with VLC ?


Here is a log message when I try to run commands with ffmpeg. As you can see, ffmpeg's internal library paths reference "vlc" :
