  • MediaSPIP 0.1 Beta version

    25 avril 2011, par

    MediaSPIP 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.
    If you want to use this archive for an installation in "farm mode", you will also need to proceed to other manual (...)

  • Multilang : améliorer l’interface pour les blocs multilingues

    18 février 2011, par

    Multilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
    Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela.

  • Use, discuss, criticize

  • How to measure delay in video streaming (RTMP) from NGinX server to video player in web browser ?

    2 mars 2020, par Padfoot

    I am streaming a MP4 file from AWS NGinX server (using FFMPEG) to a video player (currently using flowplayer in web page).
    I am trying to identify how long the player will take to get the first packet of frames from the server. Is there any utility or method to measure.

    I have already checked few previous questions in stackoverflow, and found out about webrtc chrome://webrtc-internals/.

  • Measure volume using ffmpeg ?

    20 septembre 2018, par Bill Greer

    Is it possible to measure decibels using ffmpeg or some other command line utility ? It does not exactly need to be decibels I just need peaks and values, etc. Some arbitrary measurement where I can tell when the decibel level has increased x% or something close.

  • How can I quantitatively measure gstreamer H264 latency between source and display ?

    16 décembre 2014, par KevinM

    I have a project where we are using gstreamer , x264, etc, to multicast a video stream over a local network to multiple receivers (dedicated computers attached to monitors). We’re using gstreamer on both the video source (camera) systems and the display monitors.

    We’re using RTP, payload 96, and libx264 to encode the video stream (no audio).

    But now I need to quantify the latency between (as close as possible to) frame acquisition and display.

    Does anyone have suggestions that use the existing software ?

    Ideally I’d like to be able to run the testing software for a few hours to generate enough statistics to quantify the system. Meaning that I can’t do one-off tests like point the source camera at the receiving display monitor displaying a high resolution and manually calculate the difference...

    I do realise that using a pure software-only solution, I will not be able to quantify the video acquisition delay (i.e. CCD to framebuffer).

    I can arrange that the system clocks on the source and display systems are synchronised to a high accuracy (using PTP), so I will be able to trust the system clocks (else I will use some software to track the difference between the system clocks and remove this from the test results).

    In case it helps, the project applications are written in C++, so I can use C event callbacks, if they’re available, to consider embedding system time in a custom header (e.g. frame xyz, encoded at time TTT - and use the same information on the receiver to calculate a difference).
