  • Changer son thème graphique

    22 février 2011, par

    Le thème graphique ne touche pas à la disposition à proprement dite des éléments dans la page. Il ne fait que modifier l’apparence des éléments.

  • Initialisation de MediaSPIP (préconfiguration)

    20 février 2010, par

    Lors de l’installation de MediaSPIP, celui-ci est préconfiguré pour les usages les plus fréquents.
    Cette préconfiguration est réalisée par un plugin activé par défaut et non désactivable appelé MediaSPIP Init.
    Ce plugin sert à préconfigurer de manière correcte chaque instance de MediaSPIP. Il doit donc être placé dans le dossier plugins-dist/ du site ou de la ferme pour être installé par défaut avant de pouvoir utiliser le site.

  • ffmpeg use gpu to encode mpeg4 to ts/m3u8 [closed]

    14 novembre 2024, par danielRICADO

    using ffmpeg I want to trim and transcode a mpeg4 from ts / m3u8

    


    std::string ffmpeg_command = "ffmpeg -hwaccel drm -i " + output_dir + input_file +
                         " -ss 00:00:00.00 -t 31 -c:v " + codec + " -b:v " + std::to_string(bitrate) +
                         " -vf scale=" + std::to_string(width) + "x" + std::to_string(height) +
                         " -hls_time " + std::to_string(30) + " -hls_list_size 0 -hls_segment_filename " +
                         ts_file_pattern + " -f hls " + m3u8_file;


    


    I wanted to choose between codecs based on the system, if gpu is avaiable I'd like to opt to use it, right now I just check if the codec is available

    


    bool is_h264_v4l2m2m_available() {
    std::string result = exec_command("ffmpeg -encoders 2>&1");
    return result.find("h264_v4l2m2m") != std::string::npos;
}


    


    if it is a I wanted to move that process over to the gpu, not just use libx264. Here is the error log. Studying hard on the solution but wold super apperciate any expert advice.

    


    other considerations are - runs in a docker container on a pi5, pibian on the host apline on in the container, container runs in privledged mode

  • FFMPEG update from 5.0 to 6.0 out_0_0 buffer queued [closed]

    16 mai 2023, par Kevitto

    I've been using ffmpeg 5.0 for some time, encoding an audio stream to an rtp server, but since I updated to ffmpeg 6.0 I get this :

    


    [out_0_0 @ 0x55ac187b60] 100 buffers queued in out_0_0, something may be wrong.


    


    Below is the ffmpeg call :

    


    ffmpeg -re -f alsa -i default:CARD:card1 -ac 2 -af aresample=async=1 -acodec libopus -b:a 48000 -f rtp "rtp://127.0.0.1:5002"

    I tried changing the output to -f null /dev/null to see if the rtp was the issue, but I get the same thing. I made sure the user running it was a member to the "audio" group and arecord -l and aplay -l both show the card with the right name and information. I even tried to use its hw code instead of the default name, and same issue.
