[FFmpeg-devel] [PATCH 15/15] lavu, lavfi, ffmpeg: Remove experimental OpenCL API
Mark Thompson
sw at jkqxz.net
Tue Nov 14 21:47:30 EET 2017
This was added in early 2013 and abandoned several months later; as far as
I can tell, there are no external users. Future OpenCL use will be via
hwcontext, which requires neither special OpenCL-only API nor global state
in libavutil.
All internal users are also deleted - this is just the unsharp filter
(replaced by unsharp_opencl, which is more flexible) and the deshake filter
(no replacement).

As suggested several times on IRC.
