    31 mai 2013, par

    Lorsque l’on gère plusieurs (voir plusieurs dizaines) de MediaSPIP sur la même installation, il peut être très pratique d’obtenir d’un coup d’oeil certaines informations.
    Cet article a pour but de documenter les scripts de monitoring Munin développés avec l’aide d’Infini.
    Ces scripts sont installés automatiquement par le script d’installation automatique si une installation de munin est détectée.

  • 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.

  • libavfilter : vf_scale : Properly take in->color_range into account

    23 février 2022, par Martin Storsjö
    libavfilter : vf_scale : Properly take in->color_range into account

    While swscale can be reconfigured with sws_setColorspaceDetails,
    
the in/out ranges also need to be set before calling
    
sws_init_context, otherwise the initialization might choose
    
fastpaths that don't take the ranges into account.
    

    Therefore, look at in->color_range too, when deciding on whether
    
the scaler needs to be reconfigured.
    

    Add a new member variable for keeping track of this, for being
    
able to differentiate between whether the scale filter parameter
    
"in_range" has been set (which should override whatever the input
    
frame has set) or whether it has been configured based on the
    
latest frame (which should trigger reconfiguring the scaler if
    
the input frame ranges change).

  • Vcpkg building FFmpeg with libxml2

    15 décembre 2019, par Subestima

    First off all im a newbie in this area so if im asking something really stupid or non sense im sorry in advance, so lets get right to the point... im trying to add features to the ffmpeg, and by what i know i have to modify CONTROL file and portfile.cmake but as it seems its not enough i dont understand the errors and i cant get more info about this in the internet so if you could give me some info how to do it properly it would allready mean a lot to me ! i will leave the portions of code and error file

  • Cannot play local RTP stream

    24 janvier 2020, par gdogg371

    I have been struggling along with this issue now for a while, but am making good progress. I now have a 4k transport stream running using the below command line arguments for VLC :

    vlc --ffmpeg-hw --avcodec-hw=any dshow:// :dshow-vdev="Video (00 Pro Capture HDMI 4K+)" :dshow-adev="Audio (2- 00 Pro Capture HDMI 4K+)" :dshow-threads=8 :dshow-aspect-ratio=16\:9 :dshow-size="3840x2160" :dshow-pixel_format=yuv444p16le :dshow-tune=film :dshow-preset=lossless :dshow-profile=main10 show-vcodec=hevc_nvenc :dshow-fps=50 :dshow-crf=0 :dshow-acodec=mp4a :dshow-stereo-mode=5 :dshow-force-surround-sound=0 :dshow-ab=128 :dshow-samplerate=44100 :no-dshow-config :live-caching=3000 --sout "#transcode{venc=ffmpeg,vcodec=mpgv,threads=8,aspect=16:9,width=3840,height=2160,fps=50,acodec=a52,ab=1500,channels=6,samplerate=48000,soverlay}:rtp{dst=239.255.0.1,port=5004,mux=ts}"

    I can access the rtp stream on the same PC as I am running the stream from with the below :

    vlc -vvv rtp://@239.255.0.1:5004

    However, if I try the same commands on a different computer, connected via Ethernet to the same network, the client VLC session just hangs. I have included the log below with the verbosity set to debug. Can anyone spot anything in here suggesting why the stream won’t play ?
