  • 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.

  • Initializing hwaccel_context in libavcodec

    3 January 2018, by dloman

    I am trying to get hardware accelerated video working using libavcodec. I am using the hw_decode.c example as a starting point and am unable to get it to work. both AVCodecContext->hwaccel and AVCodecContext->hwaccel_context are NULL

    I belive some part of the hwaccel is working as I see the output

    libva info: VA-API version 0.39.0
    
libva info: va_getDriverName() returns 0
    
libva info: Trying to open /usr/lib/x86_64-linux-gnu/dri/i965_drv_video.so
    
libva info: Found init function __vaDriverInit_0_39
    
libva info: va_openDriver() returns 0

    Which is the same as when I run

    ffmpeg -hwaccel vaapi -hwaccel_device /dev/dri/renderD128 -hwaccel_output_format vaapi -i input.mpg -f null -

    but immediately after that I get the following error message

    [h264 @ 0x1df2cc0] Hardware acceleration context (hwaccel_context) does not exist.
    
Failed to get HW surface format.
    
[h264 @ 0x1df2cc0] decode_slice_header error
    
[h264 @ 0x1df2cc0] no frame!

    I looked at the similar question and the answer to this shows how to get a AVCodecContext->hwaccel. But even with the AVCodecContext->hwaccel being a valid VAApih264 decoder I still get the same error message.

    How do I initialize a AVCodecContext->hwaccel_context and after that what else do I need to do to get hardware accelerated video working in ffmpeg?

  • FFMPEG Library MP3 Encoder

    13 March 2013, by David Tay

    Does the ffmpeg library come with an MP3 encoder?

    This:

    AVCodec *pCodec = avcodec_find_encoder(AV_CODEC_ID_MP3);

    always returns null. I also tried AV_CODEC_ID_MP3ADU and AV_CODEC_ID_MP3ON4, they too return null. The only encoding codec I've found is AV_CODEC_ID_MP2.

    Any help appreciated
