OK and thank you, these do work fine and produce handy results and the
documentation you linked works.
".\ffmpeg_3.latest_master.exe" -v verbose -init_hw_device list
".\ffmpeg_3.latest_master.exe" -v verbose -init_hw_device opencl
I'll head over to ffmpeg-user (and do some reading) to find out what
concepts/knowledge
I'm missing in regard to specifying parameters for hardware acceleration
and why the below didn't work with
"Impossible to convert between the formats supported by the filter
'Parsed_yadif_0' and the filter 'auto_scaler_0'"
"Failed to inject frame into filter network: Function not implemented"
P.S. really nice work !!
