  • Multilang : améliorer l’interface pour les blocs multilingues

    18 February 2011, by

    Multilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
    Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela.

  • Les tâches Cron régulières de la ferme

    1 December 2010, by

    La gestion de la ferme passe par l’exécution à intervalle régulier de plusieurs tâches répétitives dites Cron.
    Le super Cron (gestion_mutu_super_cron)
    Cette tâche, planifiée chaque minute, a pour simple effet d’appeler le Cron de l’ensemble des instances de la mutualisation régulièrement. Couplée avec un Cron système sur le site central de la mutualisation, cela permet de simplement générer des visites régulières sur les différents sites et éviter que les tâches des sites peu visités soient trop (...)

  • lavc/qsvenc_hevc: restore the default gop size

    lavc/qsvenc_hevc: restore the default gop size

    commit a3c0a3e changed the default settings and expected the runtime can
    
choose a best value. However the runtime doesn't set a valid gop size
    
for hevc encoder, hence the output steam is non-seekable, which is
    
inconvenient to user [1][2]

    vaapi_encode: Destroy output buffer pool before VA context

    The buffers are created associated with the context, so they should be
    
destroyed before the context is.  This is enforced by the iHD driver.

  • Use ffmpeg to extract/remix audio from/into video

    2 December 2023, by user37143

    Working on a Mac, I have a bunch of .mkv files that I want to extract the audio from, then use an ML model I have in order to translate them and then mix them back into the video.

    &#xA;

    For the extraction phase, I am running:&#xA;ffmpeg -i {input_video}.mkv -map 0:a -c copy {output_audio}.aac&#xA;however I am getting these errors:

    &#xA;

    [adts @ 0x130708b30] Only AAC streams can be muxed by the ADTS muxer&#xA;[out#0/adts @ 0x6000031943c0] Could not write header (incorrect codec parameters ?): Invalid argument&#xA;[aost#0:1/copy @ 0x13070a050] Error initializing output stream: &#xA;

    &#xA;

    which I suspect are because of subtitles, seeing these warnings earlier in the output:

    &#xA;

    [matroska,webm @ 0x130704260] Could not find codec parameters for stream 4 (Subtitle: (pgssub)): unspecified size&#xA;Consider increasing the value for the &#x27;analyzeduration&#x27; (0) and &#x27;probesize&#x27; (5000000) options&#xA;[matroska,webm @ 0x130704260] Could not find codec parameters for stream 5 (Subtitle:  (pgssub)): unspecified size&#xA;Consider increasing the value for the &#x27;analyzeduration&#x27; (0) and &#x27;probesize&#x27; (5000000) options&#xA;[matroska,webm @ 0x130704260] Could not find codec parameters for stream 6 (Attachment: none): unknown codec&#xA;Consider increasing the value for the &#x27;analyzeduration&#x27; (0) and &#x27;probesize&#x27; (5000000) options&#xA;

    &#xA;

    The only command that has worked for me so far is&#xA;ffmpeg -i {input_video}.mkv -vn -c:a aac {output_aduio}.wav which however created a completely empty audio file.

    &#xA;

    Any help would be greatly appreciated
