  • Ajouter notes et légendes aux images

    7 février 2011, par

    Pour pouvoir ajouter notes et légendes aux images, la première étape est d’installer le plugin "Légendes".
    Une fois le plugin activé, vous pouvez le configurer dans l’espace de configuration afin de modifier les droits de création / modification et de suppression des notes. Par défaut seuls les administrateurs du site peuvent ajouter des notes aux images.

  • 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" (...)

  • Emulate radio stream metadata

    17 juin 2018, par IllidanS4

    I work with an application that can connect to an audio stream via HTTP and play the audio. It can also connect to SHOUTcast and Icecast radios and play the streams, but for some radios, when the format is supported, it can read special metadata as well, like the name of the current song.

    I would like to use ffmpeg to produce an MP3 stream that contains the specific metadata this application understands. I know it is probably something specific to SHOUTcast or Icecast and not to the format itself, but I don’t know what exactly it is that the application can decode.

    If ffmpeg cannot produce such a stream (possibly because it is part of the HTTP metadata), I would welcome any details on how the metadata is encoded and how can I generate it (in PHP for example).

  • Discord FFmpegPCMAudio bad audio quality

    17 mars 2021, par Yareyare

    I'm writing a discord music bot in python and encountered some audio quality issue. When I use discord.FFmpegPCMAudio("song.mp3") to play a mp3 file downloaded using youtube_dl in a channel, there're sometimes intermittent background noice and it sounds laggy and broken.
    
I tried to pass {'vbr':5} as an argument, and also tried discord.FFmpegOpusAudio, but doesn't do any better. The file itself is not corrupted, since it sounds normal when I play it using another app. Internet connection also isn't the cause, as each time I play the same file, the exact audio quality issue occurs at the exact same time.
    
I'm quite stuck right now. What other factors may caused this audio quality loss ?

    lavfi : add opencl tonemap filter
    

    This filter does HDR(HDR10/HLG) to SDR conversion with tone-mapping.

    An example command to use this filter with vaapi codecs :
    FFMPEG -init_hw_device vaapi=va :/dev/dri/renderD128 -init_hw_device \
    opencl=ocl@va -hwaccel vaapi -hwaccel_device va -hwaccel_output_format \
    vaapi -i INPUT -filter_hw_device ocl -filter_complex \
    '[0:v]hwmap,tonemap_opencl=t=bt2020:tonemap=linear:format=p010[x1] ; \
    [x1]hwmap=derive_device=vaapi:reverse=1' -c:v hevc_vaapi -profile 2 OUTPUT
