  • Initialisation de MediaSPIP (préconfiguration)

    20 février 2010, par

    Lors de l’installation de MediaSPIP, celui-ci est préconfiguré pour les usages les plus fréquents.
    Cette préconfiguration est réalisée par un plugin activé par défaut et non désactivable appelé MediaSPIP Init.
    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.

  • ffserver + ffmpeg, out rtsp stream : why ffplay cannot play the stream, but movie player can

    18 juillet 2014, par user1914692

    Ubuntu 12.04
    I use ffserver + ffmpeg.

    There are a little revision of the original /etc/ffserver.conf :

    RTSPPort 5454
    
RTSPBindAddress 0.0.0.0
    

    
# ...
    

    
<stream>
    
Format rtp
    
# coming from live feed 'feed1'
    
Feed feed1.ffm
    
</stream>

    The command of ffmpeg (Option 1) is :

    ffmpeg -re -i '/usr/share/red5/webapps/oflaDemo/streams/hobbit_vp6.flv'  http://localhost:8090/feed1.ffm

    BTW, if I use Option 2 as below, it does not work :

    ffmpeg -re -i '/usr/share/red5/webapps/oflaDemo/streams/hobbit_vp6.flv'  http://192.168.1.105:8090/feed1.ffm
    
## not work:
    
[http @ 0x21a9c80] HTTP error 404 Not Found
    
http://192.168.1.105:8090/feed1.ffm: Input/output error

    So now I need to display the stream.
    On the other computer :

    (Option 1) ffplay rtsp://192.168.1.105:5454/test2-rtsp.mpg

    Not work. [Output] rtsp UDP timeout, retrying with TCP.
    Why ?

    (Option 2) movie player : Open location : rtsp ://192.168.1.105:5454/test2-rtsp.mpg
    it works !

  • FFServer streaming H.264 from Logitech C920

    23 octobre 2014, par Ricardo Frederico Leote Mota

    I’m having some trouble trying to implement a web live stream from my Logitech C920 webcam w/ H.264 encoding using ffmpeg/ffserver.

    Here is the configuration file I’m using for the ffserver :

    # 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.
    
Port 8090
    

    
# Address on which the server is bound. Only useful if you have
    
# several network interfaces.
    
BindAddress 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.
    
CustomLog -

# 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:
    
#

    And I can’t watch the stream on the web browser side also.

    Could someone give me an hint on this ?
