  • 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.

    


    I have been following this example from ffmpeg Github repo.

    


    It fails for me here :

    


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


    


    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.

    


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

    


    libva info: VA-API version 1.7.0
libva info: Trying to open /usr/lib/x86_64-linux-gnu/dri/iHD_drv_video.so
libva info: Found init function __vaDriverInit_1_7
libva info: va_openDriver() returns 0

      VAProfileHEVCMain10             : VAEntrypointVLD
      VAProfileVP9Profile0            : VAEntrypointVLD
      VAProfileVP9Profile2            : VAEntrypointVLD


    


    Thanks !

    


  • ffmpeg and NVIDIA GPU

    14 mars 2021, par Ali Gökkaya

    I want to broadcast only when there is motion from the cameras that I get video from. I have one NVDIA XAVIAR for this, I think this work can be done with ffmpeg.

    


    According to my research, I read an article like NVIDIA does not support FFMPEG. Your information on this subject and the resources you will give me will be very valuable.

    


    Can I run pips for motion event for NVIDIA driver ?
