 I am using ffmpeg exe to Encode videos and for the files with encoder
 HEVC, the output looks washed out. I did some research and found the
 following -vf parameter would help

  -i C:\test\ffmpeg\input.MOV -vcodec libx264  -vprofile high   -preset
 fast   -minrate 2500k -maxrate 4500k -bufsize 3000k **-vf
 zscale=t=linear,tonemap=tonemap=hable** -map_metadata -1  -threads 0  -ac
 2  -b:a 128k  -r 30  -ar 44100  -pix_fmt yuv420p  -y
 C:\test\ffmpeg\converted.mp4

 For certain files, this does work and for some others, I get the following
 error

 [vf#0:0 @ 0000015cdd304940] Error while filtering: Generic error in an
 external library
 Error while filtering: Generic error in an external library

 Is there anything that wrong on the above parameters?
