  • Installation en mode ferme

    4 février 2011, par

    Le mode ferme permet d’héberger plusieurs sites de type MediaSPIP en n’installant qu’une seule fois son noyau fonctionnel.
    C’est la méthode que nous utilisons sur cette même plateforme.
    L’utilisation en mode ferme nécessite de connaïtre un peu le mécanisme de SPIP contrairement à la version standalone qui ne nécessite pas réellement de connaissances spécifique puisque l’espace privé habituel de SPIP n’est plus utilisé.
    Dans un premier temps, vous devez avoir installé les mêmes fichiers que l’installation (...)

  • HTML5 icecast stream and pausing stream to add advert

    2 avril 2019, par RussellHarrower

    So I have not found a good solution to add audio advertising to our radio station for users who are not in the stations main area (western Australia).

    So I was wondering is there away that anyone knows of, that would allow a code be it ffmpeg or java/JavaScript to listen for the song that is currently playing (it maybe delayed by 30seconds) and after the song ends start an audio ad from a mongodb database.

    I know how to do the mongodb database part.

    What I need to figure out is how to detect that the song is finishing or other option is to store the stations adverts in the db as raw data or even better we could air a 0.1sec file that is just blank and that filename tells the script to lower audio player ones volume and boost audio two volume.

    When station ads end we play another filename with same length and reverse the process.

    Ok sorry if that’s me thinking out loud but if you have any ideas that would be great.

    The only issue with above is TuneIn app won’t work with an IFrame we need to supply them an audio url.

    So if anyone know how to do this in ffmpeg and only require 1 url which can detect users location that be better solution.

    All ideas welcomed and yes I googled and Bing searched however I don’t have 30,000$ for hardware companies are selling. There has to be an open source solution.

  • How to encode H.264 video using FFmpeg C API and then open the output with a media player ?

    4 avril 2016, par GummiB

    I’m trying to encode a H.264 video with the FFMPEG C API.
    I have successfully compiled and executed the decoding/encoding example provided by FFMPEG.

    The problem I’m facing is that the .mpg file (encoded with AV_CODEC_ID_MPEG1VIDEO) the example creates works. Windows creates a thumbnail and everything. On the other hand the .h264 (encoded with AV_CODEC_ID_H264) file does not. When I try to play the file in VLC the play/pause button just flickers, no thumbnail in windows, no nothing.

    During encoding libx264 reports the following :
