  • Creating farms of unique websites

    13 avril 2011, par

    MediaSPIP platforms can be installed as a farm, with a single "core" hosted on a dedicated server and used by multiple websites.
    This allows (among other things) : implementation costs to be shared between several different projects / individuals rapid deployment of multiple unique sites creation of groups of like-minded sites, making it possible to browse media in a more controlled and selective environment than the major "open" (...)

  • HTML5 audio and video support

    The MediaSPIP player used has been created specifically for MediaSPIP and can be easily adapted to fit in with a specific theme.
    For older browsers the Flowplayer flash fallback is used.

  • De l’upload à la vidéo finale [version standalone]

    31 janvier 2010, par

    Le chemin d’un document audio ou vidéo dans SPIPMotion est divisé en trois étapes distinctes.
    Upload et récupération d’informations de la vidéo source
    Dans un premier temps, il est nécessaire de créer un article SPIP et de lui joindre le document vidéo "source".
    Au moment où ce document est joint à l’article, deux actions supplémentaires au comportement normal sont exécutées : La récupération des informations techniques des flux audio et video du fichier ; La génération d’une vignette : extraction d’une (...)

  • HlS playlist skip files with ffmpeg

    29 janvier, par tamirg

    I simply downloaded 5 mp3 files from here :
https://samplelib.com/sample-mp3.html

    


    which means i have :

    


    sample-3s.mp3
sample-6s.mp3
sample-9s.mp3
sample-12s.mp3
sample-15s.mp3


    


    and then i create a simple hls playlist sample.m3u8 :

    


    #EXTM3U
#EXT-X-TARGETDURATION:20
#EXT-X-MEDIA-SEQUENCE:0
#EXTINF:3.0,
sample-3s.mp3
#EXTINF:6.0,
sample-6s.mp3
#EXTINF:9.0,
sample-9s.mp3
#EXTINF:12.0,
sample-12s.mp3
#EXTINF:15.0,
sample-15s.mp3


    


    But when i play this playlist :

    


    ffplay sample.m3u8


    


    i get :

    


    [hls @ 0x13703b4d0] Opening 'sample-9s.mp3' for reading

    It starts playing from the file sample-9s, and not sample-3s. So it skips the first two files.
Why does it happen ?

    


  • Ffmpeg RTSP stream with size=N/A bitrate=N/A [closed]

    6 octobre 2024, par Comycos

    When I try to stream a video it seems to work but bitrate and size are N/A frame=  277 fps= 26 q=-1.0 size=N/A time=00:00:11.07 bitrate=N/A speed=1.05x

    


    I run the following command to stream a video to a RTSP server :
ffmpeg -re -stream_loop -1 -i idurre-2024-09-17-12h33m19s.mp4 -c copy -f rtsp -rtsp_transport tcp rtsp://localhost:8554/test

    


    The output ffmpeg is like this :

    But when I try to read it with ffplay nothing is showing...

    


  • FFMpegCore.Exceptions.FFMpegException : 'ffmpeg exited with non-zero exit-code'

    15 octobre 2024, par secretply

    I am looking to retrieve the loudnorm data in JSON format from FFmpeg (using FFMpegCore 5.1.0). This is the code I currently have :

    


    await FFMpegArguments
    .FromPipeInput(new StreamPipeSource(fileStream.OpenReadStream()))
    .OutputToPipe(new StreamPipeSink(outputStream), options => options.WithCustomArgument("-af loudnorm=print_format=json"))
    .ProcessAsynchronously();


    


    This is the exception I get, which is similar to this old GitHub issue.

    


    System.IO.IOException: 'Pipe is broken.'

This exception was originally thrown at this call stack:
    System.IO.Pipes.PipeStream.PipeValueTaskSource.GetResult(short)
    System.IO.Pipes.PipeStream.PipeValueTaskSource.System.Threading.Tasks.Sources.IValueTaskSource.GetResult(short)
    System.IO.Stream.CopyToAsync.__Core|27_0(System.IO.Stream, System.IO.Stream, int, System.Threading.CancellationToken) in Stream.cs
    FFMpegCore.Arguments.InputPipeArgument.ProcessDataAsync(System.Threading.CancellationToken)
    FFMpegCore.Arguments.PipeArgument.During(System.Threading.CancellationToken)
    FFMpegCore.FFMpegArguments.During(System.Threading.CancellationToken)
    FFMpegCore.FFMpegArgumentProcessor.Process(Instances.ProcessArguments, System.Threading.CancellationTokenSource)
    FFMpegCore.FFMpegArgumentProcessor.ProcessAsynchronously(bool, FFMpegCore.FFOptions)


    


    I am trying to replicate the following FFmpeg command and JSON output :

    


    ffmpeg -i "file.flac" -af loudnorm=print_format=json -f null -


    


    {
        "input_i" : "-21.87",
        "input_tp" : "-7.13",
        "input_lra" : "5.00",
        "input_thresh" : "-32.04",
        "output_i" : "-24.76",
        "output_tp" : "-10.36",
        "output_lra" : "4.10",
        "output_thresh" : "-34.84",
        "normalization_type" : "dynamic",
        "target_offset" : "0.76"
}


    


    If I add .ForceFormat("null") to the OutputToPipe options, I do not get the exception but when I read the output stream, it returns an empty string. In the issue mentioned, I know they mentioned a way to get the FFMpegErrorOutput property but I do not know how that can be done. I could not find an example of outputting a stream as JSON. If anyone can point me in the right direction or can provide an alternative solution, I would greatly appreciate it.

    


    Update

    


    I made a change to the StreamPipeSource() method where I copied over the uploaded file to a MemoryStream. With this change, the following FFMpegException is thrown.
