    I’m a beginer in ffmpep, I did my first simple project as this tutorial

  • FFMPEG hevc_nvenc "No NVENC capable devices found" with NVidia GTX950M

    5 juillet 2018, par NaturalBornCamper

    I get the error "No NVENC capable devices found" when trying a simple encoding like this, even skipping audio to make sure it’s not an audio problem :

    ffmpeg.exe -i input.mp4 -c:v hevc_nvenc -an out.mp4

    I also tried with more details, like setting the pixel format, the preset, the rate-control, the format.

    On the documentation page there :
    https://trac.ffmpeg.org/wiki/HWAccelIntro
    it says that if we get this error we should check for the pixel format. The video has yuv420p here and even specifying the format results in the same error.

    i also checked the NVidia supported cards and it says GeForce, but no details about the models :
    https://developer.nvidia.com/video-encode-decode-gpu-support-matrix#Encoder

    I tried h264_nvenc and it works perfectly however, the problem is only with hevc_nvenc
    Has anyone encountered this problem ?

    Complete console output :
