Hi :
    when i use this command
    ffmpeg -hwaccel cuda -hwaccel_output_format cuda -extra_hw_frames 2 -threads 2 -i 333_111017.JPG -pix_fmt yuv420p -f hevc 1.h265 -y
   but  i get this error:
   Impossible to convert between the formats supported by the filter 'Parsed_null_0' and the filter 'auto_scaler_0'
   Error reinitializing filters!
   Failed to inject frame into filter network: Function not implemented
   Error while processing the decoded data for stream #0:0
   How can i get correct result;
