    Ce plugin vise à gérer des sites de mise en ligne de documents de tous types.
    Il crée des "médias", à savoir : un "média" est un article au sens SPIP créé automatiquement lors du téléversement d’un document qu’il soit audio, vidéo, image ou textuel ; un seul document ne peut être lié à un article dit "média" ;

  • Anomalie #3875 : Impossible de voir les sous-rubriques

    9 février 2017, par denis -

    Juste pour préciser /158 donne en fait l’url complète /prog/2017/158/ qui pointe bien vers une rubrique.

    Et ça ne semble pas lié aux chiffres, si je crée une rubrique qui donne comme url coucou-coucou, j’ai bien accès à un article prog/2017/coucou-coucou/bonjour, si je la renomme en coucou l’url prog/2017/coucou/bonjour donne une erreur.

    C’est sans doute très marginal de se retrouver avec 2 urls /xxx et /xxx-xxx

  • ffmpeg output separate channel from an input with multiple channels

    16 février 2017, par tiras muturi

    i run this command to be able to stream a udp live stream to a http live stream that is playable using a mobile application that am building.
    its just a stream with audio streams only.

    i really want a way i can be able to map every input stream to have an output stream that can be accessed separately from the other like maybe if i need the first stream maybe i will just

    ffplay http://localhost:8090/feed1.ffm

    and if i need the 7th stream i will just

    ffplay http://localhost:8090/feed7.ffm

    Please can someone help me crack this issue. FFmpeg dont have complex examples for my current situation.

    this is my header information

  • Demultiplex UDP live stream to multiple single live stream outputs using FFMPEG & FFSERVE

    17 février 2017, par tiras muturi

    i have a problem with ffmpeg. i have an input live stream that has 8 inputs and i want to use ffmpeg to convert it from udp live steram to tcp livestream and then extract each of the 8 input stream differently.

    i have been reading about the ffmpeg documentation at they havent provided a clear way of solving my problem.

    am running

    ffmpeg version 3.2.4-1~16.04.york0 Copyright (c) 2000-2017 the FFmpeg developers built with gcc 5.4.1 (Ubuntu 5.4.1-5ubuntu2~16.04.york1) 20170210 configuration: --prefix=/usr --extra-version='1~16.04.york0' --toolchain=hardened --libdir=/usr/lib/x86_64-linux-gnu --incdir=/usr/include/x86_64-linux-gnu --enable-gpl --disable-stripping --enable-avresample --enable-avisynth --enable-gnutls --enable-ladspa --enable-libass --enable-libbluray --enable-libbs2b --enable-libcaca --enable-libcdio --enable-libebur128 --enable-libflite --enable-libfontconfig --enable-libfreetype --enable-libfribidi --enable-libgme --enable-libgsm --enable-libmp3lame --enable-libopenjpeg --enable-libopenmpt --enable-libopus --enable-libpulse --enable-librubberband --enable-libshine --enable-libsnappy --enable-libsoxr --enable-libspeex --enable-libssh --enable-libtheora --enable-libtwolame --enable-libvorbis --enable-libvpx --enable-libwavpack --enable-libwebp --enable-libx265 --enable-libxvid --enable-libzmq --enable-libzvbi --enable-omx --enable-openal --enable-opengl --enable-sdl2 --enable-libdc1394 --enable-libiec61883 --enable-chromaprint --enable-frei0r --enable-libopencv --enable-libx264 --enable-shared libavutil 55. 34.101 / 55. 34.101 libavcodec 57. 64.101 / 57. 64.101 libavformat 57. 56.101 / 57. 56.101 libavdevice 57. 1.100 / 57. 1.100 libavfilter 6. 65.100 / 6. 65.100 libavresample 3. 1. 0 / 3. 1. 0 libswscale 4. 2.100 / 4. 2.100 libswresample 2. 3.100 / 2. 3.100 libpostproc 54. 1.100 / 54. 1.100
