Initialisation de MediaSPIP (préconfiguration)

Ce plugin sert à préconfigurer de manière correcte chaque instance de MediaSPIP. Il doit donc être placé dans le dossier plugins-dist/ du site ou de la ferme pour être installé par défaut avant de pouvoir utiliser le site.
Dans un premier temps il active ou désactive des options de SPIP qui ne le (...) -

Anomalie #2866 : SPIP sous estime les visites de 30 à 50% par rapport à Google Analytics
16 mai 2013, par cedric -C’est normal d’avoir des fichiers dans tmp/visites/
Ce sont toutes les visites en cours (aka les internautes qui ont vu une page depuis moins de 30min) puisque l’on attend qu’une visite soit finie pour la dépouiller. Cela n’a donc rien à voir avec un écart de mesure.Pour comprendre cet écart de mesure, il faudrait analyser finement les logs apache, peut être instrumenter le code, croiser avec google analytics etc. Quel est le site concerné ?

AppRTC : Google’s WebRTC test app and its parameters
23 juillet 2014, par silviaIf you’ve been interested in WebRTC and haven’t lived under a rock, you will know about Google’s open source testing application for WebRTC : AppRTC.
When you go to the site, a new video conferencing room is automatically created for you and you can share the provided URL with somebody else and thus connect (make sure you’re using Google Chrome, Opera or Mozilla Firefox).
We’ve been using this application forever to check whether any issues with our own WebRTC applications are due to network connectivity issues, firewall issues, or browser bugs, in which case AppRTC breaks down, too. Otherwise we’re pretty sure to have to dig deeper into our own code.
Now, AppRTC creates a pretty poor quality video conference, because the browsers use a 640×480 resolution by default. However, there are many query parameters that can be added to the AppRTC URL through which the connection can be manipulated.
Here are my favourite parameters :
- hd=true : turns on high definition, ie. minWidth=1280,minHeight=720
- stereo=true : turns on stereo audio
- debug=loopback : connect to yourself (great to check your own firewalls)
- tt=60 : by default, the channel is closed after 30min – this gives you 60 (max 1440)
For example, here’s how a stereo, HD loopback test would look like : https://apprtc.appspot.com/?r=82313387&hd=true&stereo=true&debug=loopback .
This is not the limit of the available parameter, though. Here are some others that you may find interesting for some more in-depth geekery :
- ss=[stunserver] : in case you want to test a different STUN server to the default Google ones
- ts=[turnserver] : in case you want to test a different TURN server to the default Google ones
- tp=[password] : password for the TURN server
- audio=true&video=false : audio-only call
- audio=false : video-only call
- audio=googEchoCancellation=false,googAutoGainControl=true : disable echo cancellation and enable gain control
- audio=googNoiseReduction=true : enable noise reduction (more Google-specific parameters)
- asc=ISAC/16000 : preferred audio send codec is ISAC at 16kHz (use on Android)
- arc=opus/48000 : preferred audio receive codec is opus at 48kHz
- dtls=false : disable datagram transport layer security
- dscp=true : enable DSCP
- ipv6=true : enable IPv6
AppRTC’s source code is available here. And here is the file with the parameters (in case you want to check if they have changed).
Have fun playing with the main and always up-to-date WebRTC application : AppRTC.
UPDATE 12 May 2014
AppRTC now also supports the following bitrate controls :
- arbr=[bitrate] : set audio receive bitrate
- asbr=[bitrate] : set audio send bitrate
- vsbr=[bitrate] : set video receive bitrate
- vrbr=[bitrate] : set video send bitrate
Example usage : https://apprtc.appspot.com/?r=&asbr=128&vsbr=4096&hd=true
