  • Script d’installation automatique de MediaSPIP

    25 avril 2011, par

    Afin de palier aux difficultés d’installation dues principalement aux dépendances logicielles coté serveur, un script d’installation "tout en un" en bash a été créé afin de faciliter cette étape sur un serveur doté d’une distribution Linux compatible.
    Vous devez bénéficier d’un accès SSH à votre serveur et d’un compte "root" afin de l’utiliser, ce qui permettra d’installer les dépendances. Contactez votre hébergeur si vous ne disposez pas de cela.

  • Que fait exactement ce script ?

    18 janvier 2011, par

    Ce script est écrit en bash. Il est donc facilement utilisable sur n’importe quel serveur.
    Il n’est compatible qu’avec une liste de distributions précises (voir Liste des distributions compatibles).
    Installation de dépendances de MediaSPIP
    Son rôle principal est d’installer l’ensemble des dépendances logicielles nécessaires coté serveur à savoir :
    Les outils de base pour pouvoir installer le reste des dépendances Les outils de développements : build-essential (via APT depuis les dépôts officiels) ; (...)

  • Automated installation script of MediaSPIP

    25 avril 2011, par

    To overcome the difficulties mainly due to the installation of server side software dependencies, an "all-in-one" installation script written in bash was created to facilitate this step on a server with a compatible Linux distribution.
    You must have access to your server via SSH and a root account to use it, which will install the dependencies. Contact your provider if you do not have that.
    The documentation of the use of this installation script is available here.

  • Compile ffmpeg for armv7s

    14 août 2014, par user3929400

    I am trying to compile ffmpeg on OSX 10.9. I want to use the ffmpeg framework in an iOS testapplication using xCode.

    I want to link the libfaac to ffmpeg and compile it for armv7s. When I follow the compilation guide (https://trac.ffmpeg.org/wiki/CompilationGuide/MacOSX) on the ffmpeg site, it does not work.

    I used the following configuration :

    ./configure  --prefix=/usr/local --enable-gpl --enable-nonfree --enable-libass --enable-libfdk-aac --enable-libfreetype --enable-libmp3lame --enable-libopus --enable-libtheora --enable-libvorbis --enable-libvpx --enable-libx264 --enable-libxvid --arch=armv7s

    Another configuration I tried is

    ./configure  --prefix=/usr/local --enable-gpl --enable-nonfree --enable-libass --enable-libfdk-aac --enable-libfreetype --enable-libmp3lame --enable-libopus --enable-libtheora --enable-libvorbis --enable-libvpx --enable-libx264 --enable-libxvid --arch=armv7s --enable-cross-compile --target-os=darwin

    The difference between both configuration is the cross compile and target os.

    Both configuration produces the following error message :

    GNU assembler not found, install gas-preprocessor

    Although, I have copied gas-preprocessor.pl into the directories /usr/local/bin and /usr/bin and modified the file read-write props by using chmod +x gas-preprocessor.pl

    Can somebody help me to configure ffmpeg by giving for example an example configuration which does work ?

  • Cannot get JACK Audio/Netjack working over LAN

    19 septembre 2016, par James

    I’m trying to stream low latency audio between 2 raspberry pis. Both gstreamer and ffmpeg induce 2+ second delays for me.

    I’ve played around with Jack Audio and locally on a single pi it seems promising. I can route mic input to a speaker locally and it is almost instantaneous.

    However, I have been having trouble getting it to route between devices using Netjack.

    # ON SERVER
    
jackd -P70 -p16 -t2000 -dalsa -dhw:1 -p128 -n3 -r44100 -s 
    

    
# ON CLIENT
    
jackd -v -R -P70 -dnetone -i1 -o1 -I0 -O0  -r44100 -p128 -n3
    

    
# ON SERVER
    
jack_netsource -H < ip address of client >
    
jack_lsp # list availible connection ports
    

    
>system:capture_1
    
>system:playback_1
    
>system:playback_2
    
>netjack:capture_1
    
>netjack:capture_2
    
>netjack:capture_3
    
>netjack:playback_1
    
>netjack:playback_2
    
>netjack:playback_3
    

    
jack_connect system:capture_1 system:playback_1 # this works
    
jack_connect system:capture_1 netjack:playback_1 # this doesn't work :(

    Most of the launch options I pulled from here http://wiki.linuxaudio.org/wiki/raspberrypi#using_jack. I’ll be honest I don’t really know what they do.

    The client jackd output shows messages like

    Jack: data not valid
    
Jack: data not valid
    
Jack: JackSocketServerChannel::Execute : fPollTable i = 1 fd = 6
    
Jack: JackRequest::Notification
    
Jack: JackEngine::ClientNotify: no callback for notification = 3
    
Jack: JackEngine::ClientNotify: no callback for notification = 3
    
netxruns... duration: 139ms
    
Jack: JackSocketServerChannel::Execute : fPollTable i = 1 fd = 6
    
Jack: JackRequest::Notification
    
Jack: JackEngine::ClientNotify: no callback for notification = 3
    
Jack: JackEngine::ClientNotify: no callback for notification = 3

    And the server jack_netsource output looks like

    current latency 114
    
current latency 20
    
current latency 27
    
current latency 29
    
current latency 48
    
current latency 23
    
current latency 33
    
current latency 28
    
current latency 41
    
current latency 84
    
current latency 44

    and the server jackd output looks like

    JackAudioDriver::ProcessGraphAsyncMaster: Process error
    
JackAudioDriver::ProcessGraphAsyncMaster: Process error
    
JackAudioDriver::ProcessGraphAsyncMaster: Process error
    
JackAudioDriver::ProcessGraphAsyncMaster: Process error
    
JackEngine::XRun: client = netjack was not finished, state = Triggered
    
JackAudioDriver::ProcessGraphAsyncMaster: Process error
    
JackAudioDriver::ProcessGraphAsyncMaster: Process error
    
JackEngine::XRun: client = netjack was not finished, state = Triggered
    
JackEngine::XRun: client = netjack was not finished, state = Triggered

    I believe the -dnetone flag indicates to use Netjack2. Netjack 1, which I’ve tried with the -dnet flag results in a single Not Connected message from jack_netsource and :

    Jack: CatchHost fd = 5 err = Resource temporarily unavailable
    
Jack: CatchHost fd = 5 err = Resource temporarily unavailable
    
Jack: CatchHost fd = 5 err = Resource temporarily unavailable
    
Jack: CatchHost fd = 5 err = Resource temporarily unavailable
    
Jack: CatchHost fd = 5 err = Resource temporarily unavailable
    
Jack: JackSocketServerChannel::Execute : fPollTable i = 1 fd = 6

    from the client jackd.
