[FFmpeg-devel] [PATCH 00/15] OpenCL infrastructure, filters

[hydra3333 at gmail.com]

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 !!
