  • La file d’attente de SPIPmotion

    28 novembre 2010, par

    Une file d’attente stockée dans la base de donnée
    Lors de son installation, SPIPmotion crée une nouvelle table dans la base de donnée intitulée spip_spipmotion_attentes.
    Cette nouvelle table est constituée des champs suivants : id_spipmotion_attente, l’identifiant numérique unique de la tâche à traiter ; id_document, l’identifiant numérique du document original à encoder ; id_objet l’identifiant unique de l’objet auquel le document encodé devra être attaché automatiquement ; objet, le type d’objet auquel (...)

  • La sauvegarde automatique de canaux SPIP

    1er avril 2010, par

    Dans le cadre de la mise en place d’une plateforme ouverte, il est important pour les hébergeurs de pouvoir disposer de sauvegardes assez régulières pour parer à tout problème éventuel.
    Pour réaliser cette tâche on se base sur deux plugins SPIP : Saveauto qui permet une sauvegarde régulière de la base de donnée sous la forme d’un dump mysql (utilisable dans phpmyadmin) mes_fichiers_2 qui permet de réaliser une archive au format zip des données importantes du site (les documents, les éléments (...)

    12 avril 2022, par ThePrime

    I'm using the https://www.npmjs.com/package/live-stream-radio module, but a few times i get this error using it. How could i solve it ? My code :

    


    const NodeMediaServer = require('node-media-server');

  • How to specify streams by pid with ffmpeg, If the value of pid is duplicated ?

    22 novembre 2019, par Bo Wang

    I have a nice m2ts file and I would like to demux specific audio streams from it. Of important, this specification is needed to use PID as identifier.
    The exemplified m2ts file has 7 audio streams, which is detected by eac3to and shown below

    eac3to.exe F:\xxx 1)
    
M2TS, 1 video track, 7 audio tracks, 5 subtitle tracks, 1:40:03
    
1: Chapters, 34 chapters
    
2: h265/HEVC, 2160p24 /1.001 (16:9), 10 bits
    
3: TrueHD/AC3 (Atmos), English, 7.1 channels, 48kHz, dialnorm: -28dB
    
   (embedded: AC3, 5.1 channels, 640kbps, 48kHz, dialnorm: -27dB)
    
4: E-AC3, English, 7.1 channels, 1024kbps, 48kHz, dialnorm: -28dB
    
   (core: AC3, 5.1 channels, 576kbps, 48kHz, dialnorm: -28dB)
    
5: AC3, English, 5.1 channels, 640kbps, 48kHz, dialnorm: -27dB
    
6: AC3, English, 2.0 channels, 320kbps, 48kHz, dialnorm: -27dB
    
7: AC3, English, 2.0 channels, 320kbps, 48kHz, dialnorm: -27dB
    
8: AC3, Chinese, 2.0 channels, 448kbps, 48kHz
    
9: AC3, Chinese, 5.1 channels, 384kbps, 48kHz, 300ms

11: Subtitle (PGS), Chinese

    However, if I run
    ffmpeg.exe -hide_banner -i "F:\xxx\BDMV\STREAM\00055.m2ts", ffmpeg shows an additional audio stream as it recognizes the embedded 5.1 AC3 stream inside the 7.1 TrueHD audio stream, as independent :
