Hello. I have an issue with using yadif and OpenCL (opencl with the
latest
git updates) in combination.
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 ? Advice welcomed.

never mind. found something that works, only posted here for closure.
eg
.\ffmpeg.exe -hide_banner -v verbose -init_hw_device
