Récupération d’informations sur le site maître à l’installation d’une instance
26 novembre 2010, parUtilité
Sur le site principal, une instance de mutualisation est définie par plusieurs choses : Les données dans la table spip_mutus ; Son logo ; Son auteur principal (id_admin dans la table spip_mutus correspondant à un id_auteur de la table spip_auteurs)qui sera le seul à pouvoir créer définitivement l’instance de mutualisation ;
Il peut donc être tout à fait judicieux de vouloir récupérer certaines de ces informations afin de compléter l’installation d’une instance pour, par exemple : récupérer le (...) -
MediaSPIP 0.1 Beta version
25 avril 2011, parMediaSPIP 0.1 beta is the first version of MediaSPIP proclaimed as "usable".
The zip file provided here only contains the sources of MediaSPIP in its standalone version.
To get a working installation, you must manually install all-software dependencies on the server.

JavaCV record video in Android
11 janvier 2017, par wyxI want to record video quiet and without preview in Android. So I choice MediaRecorder but I could record only without preview but what make me crazy is that when MediaRecorder start or stop it will with a sound dee.... I try many methods about that . But I think it perhaps sth related to the OS of the mobile. So I try JavaCV because I also want to have a Live function in my app.
But JavaCV spent me to too much time to solve some strange problems because it’s my first time to do sth about C++ src and video.
Just

TCP connection refused with FFMPEG
2 février 2017, par SamulOFFICIAL EDIT :
I thank you so much for your help but I am still encountering problems.
My ffserver.conf file is like this :
# Port on which the server is listening. You must select a different
# port from your standard HTTP web server if it is running on the same
# computer.
HTTPPort 8090
# Address on which the server is bound. Only useful if you have
# several network interfaces.
HTTPBindAddress 0.0.0.0
# Number of simultaneous HTTP connections that can be handled. It has
# to be defined *before* the MaxClients parameter, since it defines the
# MaxClients maximum limit.
MaxHTTPConnections 2000
# Number of simultaneous requests that can be handled. Since FFServer
# is very fast, it is more likely that you will want to leave this high
# and use MaxBandwidth, below.
MaxClients 1000
# This the maximum amount of kbit/sec that you are prepared to
# consume when streaming to clients.
MaxBandwidth 1000
# Access log file (uses standard Apache log file format)
# '-' is the standard output.

# Definition of the live feeds. Each live feed contains one video
# and/or audio sequence coming from an ffmpeg encoder or another
# ffserver. This sequence may be encoded simultaneously with several
# codecs at several resolutions.
<feed>
# You must use 'ffmpeg' to send a live feed to ffserver. In this
# example, you can type:
#
# ffmpeg http://localhost:8090/feed1.ffm
# ffserver can also do time shifting. It means that it can stream any
# previously recorded live stream. The request should contain:
# "http://xxxx?date=[YYYY-MM-DDT][[HH:]MM:]SS[.m...]".You must specify
# a path where the feed is stored on disk. You also specify the
# maximum size of the feed, where zero means unlimited. Default:
# File=/tmp/feed_name.ffm FileMaxSize=5M
File /tmp/feed1.ffm
FileMaxSize 200K
# You could specify
# ReadOnlyFile /saved/specialvideo.ffm
# This marks the file as readonly and it will not be deleted or updated.
# Specify launch in order to start ffmpeg automatically.
# First ffmpeg must be defined with an appropriate path if needed,
# after that options can follow, but avoid adding the http:// field
#Launch ffmpeg
# Only allow connections from localhost to the feed.

# Format of the stream : you can choose among:
# mpeg : MPEG-1 multiplexed video and audio

# ogg : Ogg format (Vorbis audio codec)
# rm : RealNetworks-compatible stream. Multiplexed audio and video.

Webrtc to rtmp using ffmpeg for live streaming from webcam to browsers and mobile
6 février 2017, par Omar SuleimanI am new in live streaming, and i am working on the website to allows user to broadcasting and visitors can watch and listen the video, I use webrtc from webcam and the url is blob, so I can not find the best way to transcode webrtc to rtmp or hls to show the live streaming in the browsers as a flash and on mobile as hls. I dont know from where can i start.
what is the best way for transcoding (ffmpeg or red5 or nginx or what) - like : 1 broadcaster to 1000 viewers can watch and listen and there is many broadcasters also.
what about CPU usage.
I am used asp.net MVC
your help is very appreciated.
Thanks.
