ffmpeg ... "Impossible to convert between the formats supported by the filter"

Using the latest ffmpeg master built as at 2017.11.26, I'm having trouble deciphering what the error messages means and, more importantly, what to do about them.

Changing from -vf to -filter_complex did nothing (I had to try). The main error message seems to be 

Impossible to convert between the formats supported by the filter

I have tried to insert "format=" and "scale" before/between/after yadif and unsharp_opencl but to no avail.

I wonder, could it be something to do with needing hwupload/hwdownload/hwmap or is that a red herring ?

What am I doing wrong ?

never mind. found something that works. eg

.\ffmpeg.exe -hide_banner -v verbose -init_hw_device 
opencl=ocl:1.0 -filter_hw_device ocl -i 
".\test_01.mpg" -an -map_metadata -1 -sws_flags 
lanczos+accurate_rnd+full_chroma_int+full_chroma_inp -filter_complex 
"[0:v]yadif=0:0:0,hwupload,unsharp_opencl=lx=3:ly=3:la=0.5:cx=3:cy=3:ca=0.5,hwdownload,setdar=dar=16/9" 
 -r 25 -c:v h264_nvenc -preset slow -bf 2 -g 50 -refs 3 -rc:v 
vbr_hq -rc-lookahead:v 32 -cq 22 -qmin 16 -qmax 26 -coder cabac -movflags 
+faststart -profile:v high -level 4.1 -pixel_format yuv420p -y 
".\test_01.newest.MP4"

Why not ... your device id (eg "1.0" above) can be found by looking at these

.\ffmpeg.exe -hide_banner -v verbose -init_hw_device list
.\ffmpeg.exe -hide_banner -v verbose -init_hw_device opencl
.\ffmpeg.exe -hide_banner -v verbose -init_hw_device opencl:1.0

And you can get a flavour of whats in these from their options :-

.\ffmpeg.exe -hide_banner -v verbose -h encoder=h264_nvenc 
.\ffmpeg.exe -hide_banner -v verbose -h filter=yadif 
.\ffmpeg.exe -hide_banner -v verbose -h filter=unsharp_opencl
