  • 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.

  • libavfilter - reconfigure filter graph using avfilter_graph_parse_ptr returns -22

    16 juillet 2021, par Rahul

    I am using transcode.c sample from ffmpeg examples and it is working as expected. It uses avfilter_graph_parse_ptr to setup filter graph and it works fine.

    &#xA;

    However, I need change filter graph dynamically and there avfilter_graph_parse_ptr fails. It returns -22. I am not certain if it is a valid operation to do (reconfigure) ? If it is possible, does it require more than avfilter_graph_parse_ptr and avfilter_graph_parse_ptr ? libavfilter documentation doesn't say anything about reconfigure or reset existing graph.

    &#xA;

    I can create a new graph but I am avoiding it since it is affecting the existing buffers.

    &#xA;

    Thank you for your insight.

  • FFmpeg av_hwdevice_ctx_create returns ENOMEM

    4 mars 2021, par lnogueir

    I am trying to perform h264 video encoding on a GPU using the ffmpeg's vaapi library.

    &#xA;

    I have been following this example from ffmpeg Github repo.

    &#xA;

    It fails for me here :

    &#xA;

    AVBufferRef* vaapi_encoder;&#xA;int err = av_hwdevice_ctx_create(&amp;vaapi_encoder, AV_HWDEVICE_TYPE_VAAPI,&#xA;                                 NULL, NULL, 0);&#xA;

    &#xA;

    This returns -12, which maps to ENOMEM (out of memory) error, but that doesn't make sense to me because I have plenty of memory.

    &#xA;

    For reference, this is my output after running 'vainfo' :

    &#xA;

    libva info: VA-API version 1.7.0&#xA;libva info: Trying to open /usr/lib/x86_64-linux-gnu/dri/iHD_drv_video.so&#xA;libva info: Found init function __vaDriverInit_1_7&#xA;libva info: va_openDriver() returns 0&#xA;vainfo: VA-API version: 1.7 (libva 2.6.0)&#xA;vainfo: Driver version: Intel iHD driver for Intel(R) Gen Graphics - 20.1.1 ()&#xA;vainfo: Supported profile and entrypoints&#xA;      VAProfileMPEG2Simple            : VAEntrypointVLD&#xA;      VAProfileMPEG2Main              : VAEntrypointVLD&#xA;      VAProfileH264Main               : VAEntrypointVLD&#xA;      VAProfileH264Main               : VAEntrypointEncSliceLP&#xA;      VAProfileH264High               : VAEntrypointVLD&#xA;      VAProfileH264High               : VAEntrypointEncSliceLP&#xA;      VAProfileJPEGBaseline           : VAEntrypointVLD&#xA;      VAProfileJPEGBaseline           : VAEntrypointEncPicture&#xA;      VAProfileH264ConstrainedBaseline: VAEntrypointVLD&#xA;      VAProfileH264ConstrainedBaseline: VAEntrypointEncSliceLP&#xA;      VAProfileVP8Version0_3          : VAEntrypointVLD&#xA;      VAProfileHEVCMain               : VAEntrypointVLD&#xA;      VAProfileHEVCMain10             : VAEntrypointVLD&#xA;      VAProfileVP9Profile0            : VAEntrypointVLD&#xA;      VAProfileVP9Profile2            : VAEntrypointVLD&#xA;
